[PMID: 38714452 DOI: 10.1016/j.fas.2024.04.012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/26/2023] [Revised: 04/03/2024] [Accepted: 04/28/2024] [Indexed: 05/09/2024]
Abstract
PURPOSE A lateral ankle sprain is the most common musculoskeletal injury in the physically active population. However, it is unclear how the clinical condition evolves during the period after the injury and what proportion of patients develops chronic symptoms. Therefore, the purpose of this study is to assess the evolution of patient-reported outcome measures after a first time lateral ankle sprain. METHODS A prospective clinical study assessed the patient-reported outcome measures (PROMs) of a consecutive group of 100 patients during 1 year after a first lateral ankle sprain. The Karlsson score and Foot and Ankle Outcome Score (FAOS) were assessed at 6 weeks, 3 months, 6 months, 9 months and 1 year. The Cumberland Ankle Instability Tool (CAIT)-score was assessed at 6 months, 9 months and 1 year. The difference between the time points of all scores was analysed using the positive change over time (binomial test versus 50%) and the difference in score (signed rank test). The time to sustained excellent level was also assessed overall and in several subgroups: age, gender, degree of injury (2 or 3), avulsion fracture, use of crutches, use of cast. Differences between subgroups were assessed by a generalized log-rank test. RESULTS All clinical scores demonstrated an improvement up to 12 months after the sprain. The median Karlsson score (interquartile range) improved from 62 (50-80) at 6 weeks to 90 (72-100) at 3 months, to 97 (82-100) at 6 months to 100 (90-100) at 9 months, to 100 (100-100) at 1 year. The analysis of positive change over time demonstrated a significant positive change (P-value <.0005) between all time points except between 6 weeks and 12 weeks when using the FAOS quality score. The difference in score demonstrated a significant change (P-value <.01) between all time points except between 36 weeks and 48 weeks when using the FAOS pain and FAOS sports score. Age and presence of an avulsion fracture were correlated with a slower recovery and worse results. At 1 year, in total 13 patients (13%) had a worse outcome corresponding to a Karlsson score < 81 or CAIT score < 24. CONCLUSION The clinical condition after a first ankle sprain demonstrated a significant improvement in PROMs between the different time points in the first year. Twelve months after a first lateral ankle sprain 13% had a fair or poor outcome. Higher age and presence of an avulsion fracture were correlated with a slower recovery and worse results. This information is useful in clinical practice to predict further progression and inform patients. Moreover, it is valuable to improve treatment strategies. LEVEL OF EVIDENCE Level II (prospective cohort study).

Exploring biomechanical variations in ankle joint injuries among Latin dancers with different stance patterns: utilizing OpenSim musculoskeletal models. Front Bioeng Biotechnol 2024; 12:1359337. [PMID: 38659647 PMCID: PMC11039862 DOI: 10.3389/fbioe.2024.1359337] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2023] [Accepted: 03/22/2024] [Indexed: 04/26/2024] Open
Abstract
Background: Dancers represent the primary demographic affected by ankle joint injuries. In certain movements, some Latin dancers prefer landing on the Forefoot (FT), while others prefer landing on the Entire foot (ET). Different stance patterns can have varying impacts on dancers' risk of ankle joint injuries. The purpose of this study is to investigate the differences in lower limb biomechanics between Forefoot (FT) dancers and Entire foot (ET) dancers. Method: A group of 21 FT dancers (mean age 23.50 (S.D. 1.12) years) was compared to a group of 21 ET dancers (mean age 23.33 (S.D. 0.94) years), performing the kicking movements of the Jive in response to the corresponding music. We import data collected from Vicon and force plates into OpenSim to establish musculoskeletal models for computing kinematics, dynamics, muscle forces, and muscle co-activation. Result: In the sagittal plane: ankle angle (0%-100%, p < 0.001), In the coronal plane: ankle angle (0%-9.83%, p = 0.001) (44.34%-79.52%, p = 0.003), (88.56%-100%, p = 0.037), ankle velocity (3.73%-11.65%, p = 0.017) (94.72-100%, p = 0.031); SPM analysis revealed that FT dancers exhibited significantly smaller muscle force than ET dancers around the ankle joint during the stance phase. Furthermore, FT dancers displayed reduced co-activation compared to ET dancers around the ankle joint during the descending phase, while demonstrating higher co-activation around the knee joint than ET dancers. Conclusion: This study biomechanically demonstrates that in various stance patterns within Latin dance, a reduction in lower limb stance area leads to weakened muscle strength and reduced co-activation around the ankle joint, and results in increased ankle inversion angles and velocities, thereby heightening the risk of ankle sprains. Nevertheless, the increased co-activation around the knee joint in FT dancers may be a compensatory response for reducing the lower limb stance area in order to maintain stability.

Front Physiol 2024; 15:1324924. [PMID: 38645693 PMCID: PMC11026675 DOI: 10.3389/fphys.2024.1324924] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/12/2023] [Accepted: 03/20/2024] [Indexed: 04/23/2024] Open
Abstract
Purpose: The effects of the combination of strength training and acupuncture on chronic ankle instability have not been studied. This study examined effects of strength training combined with acupuncture on balance ability, ankle motion perception, and muscle strength in chronic ankle instability among college students. Methods: Forty-six chronic ankle instability college students were randomly categorized into the experimental group (n = 24, strength training + acupuncture) and the control group (n = 22, strength training) for an 8-week intervention. Results: For the results at 8 weeks, compared with the baseline, in the experimental group, the chronic Ankle Instability Tool (CAIT) score, ankle dorsiflexion, plantar flex, eversion peak torque (60°/s), and plantar flex peak torque (180°/s) increased by 13.7%, 39.4%, 13.7%, 14.2%, and 12.3%, respectively. Dorsiflexion, plantar flexion, inversion, and eversion kinesthetic sensation test angles decreased by 17.4%, 20.6%, 15.0%, and 17.2%, respectively. Anterior-posterior and medial-lateral displacement, and anterior-posterior and medial-lateral velocity decreased by 28.9%, 31.6%, 33.3%, and 12.4%, respectively. Anterior-posterior and medial-lateral displacement, and anterior-posterior and medial-lateral mean velocity decreased by 28.9%, 31.6%, 33.3%, and 12.4%, respectively. In the control group, the Cumberland Ankle Instability Tool score and the ankle dorsiflexion peak torque (60°/s) increased by 13.8% and 17.9%, respectively. The inversion kinesthetic sensation test angle decreased by 15.2%, whereas anterior-posterior and medial-lateral displacement, and anterior-posterior and medial-lateral mean velocity decreased by 17.1%, 29.4%, 12.3%, and 16.8%, respectively. 2) For the comparison between the groups after 8 weeks, the values of ankle dorsiflexion and plantar flex peak torque (60°/s) in the experimental group were greater than those in the control group. The values of ankle plantar flex kinesthetic sensation test angle, the anterior-posterior displacement, and anterior-posterior mean velocity in the experimental group were lower than those in the control group. Conclusion: Acupuncture treatment in conjunction with muscle strength training can further improve the balance ability of anterior-posterior, ankle dorsiflexion, and plantar flex strength and plantar flex motion perception in chronic ankle instability participants.

[PMID: 38582141 DOI: 10.1053/j.jfas.2024.03.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/22/2023] [Revised: 03/28/2024] [Accepted: 03/29/2024] [Indexed: 04/08/2024]
Abstract
The aim of the study was to compare the intermediate-term (>24 months) clinical outcomes between anterior talofibular ligament repair using Broström operation with and without an internal brace. Nineteen patients underwent surgery using an arthroscopic traditional Broström repair with an internal brace technique (IB) and Eighteen patients underwent surgery using an arthroscopic traditional Broström repair without an internal brace technique (TB) . All patients were evaluated clinically using the Foot and Ankle Outcome Score (FAOS) and Foot and Ankle Ability Measure (FAAM). According to FAAM, sports activity scores of TB and IB groups were 83.33 ± 5.66 and 90.63 ± 6.21 at the final follow-up (p = .02). There were no significant differences in preoperative and postoperative stress radiographs between the two groups. Total medical expense was more in the IB group (p < .001). It also has a significant superiority in the terms of FAAM scores at sports activity. However, there was no difference during daily life.

Chronic lateral ankle instability using anterior tibiofibular ligament distal fascicle transfer augmentation repair: an anatomical, biomechanical, and histological study. Front Bioeng Biotechnol 2024; 12:1326036. [PMID: 38515619 PMCID: PMC10955350 DOI: 10.3389/fbioe.2024.1326036] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/22/2023] [Accepted: 02/22/2024] [Indexed: 03/23/2024] Open
Abstract
Background: The transfer of the anterior tibiofibular ligament distal fascicle (ATiFL-DF) for the augmentation repair of the anterior talofibular ligament (ATFL) shows potential as a surgical technique. However, evidences on the benefits and disadvantages of this method in relation to ankle joint function are lacking. Purpose: This study aimed to provide comprehensive experimental data to validate the feasibility of ATiFL-DF transfer augmentation repair of the ATFL. Methods: This study included 50 embalmed ankle specimens to measure various morphological features, such as length, width, thickness, and angle, for evaluating similarities between the ATiFL-DF and ATFL. Furthermore, 24 fresh-frozen ankle specimens were examined for biomechanical testing of the ATiFL-DF transfer augmented repair of the ATFL. Finally, 12 pairs of ATiFL-DF and ATFL tissues from fresh-frozen ankle specimens were treated with gold chloride staining to analyze mechanoreceptor densities. Results: Anatomical studies found that the lengths and thicknesses of the ATFL and ATiFL-DF are similar. Biomechanical outcomes showed that performing ATiFL-DF transfer for ATFL repair can improve the stability of the talus and ankle joints. This is evident from the results of the anterior drawer, axial load, and ultimate failure load tests. However, performing ATiFL-DF transfer may compromise the stability of the distal tibiofibular joint, based on the Cotton and axial load tests at an external rotation of 5°. Analysis of the histological findings revealed that mechanoreceptor densities for four types of mechanoreceptors were comparable between the ATiFL-DF and ATFL groups. Conclusion: ATiFL-DF transfer is a viable method for augmenting ATFL repair. This technique helps to improve the stability of the talus and ankle joints while compensating for proprioception loss. Although ATiFL-DF transfer augmented repair of the ATFL may negatively affect the stability of the distal tibiofibular joint, this procedure can enhance the stability of the talus and ankle joints.

Abstract
Lateral ligament injuries are the most common injuries of the ankle joint and are usually treated with early weight bearing after a short period of immobilization. If the clinical presentation is suspicious, additional injuries to the deltoid ligament complex and the syndesmosis should be considered. The indications for additional diagnostics should be generously applied. Injuries to the deltoid ligament usually occur as part of a complex ankle injury and should also be addressed in the surgical treatment of accompanying injuries. Chronic instability in this area necessitates complex bony and soft tissue procedures. Syndesmotic injuries with insufficiency of the capsule-ligament apparatus are frequent in ankle fractures and are stabilized during fracture treatment. Isolated syndesmotic instability should also be surgically treated as chronic injuries are usually associated with poor clinical results and early osteoarthritis.

Clinical Outcomes and Return to Preinjury Sports After Anatomic Reconstruction With a Gracilis Autograft Versus the Modified Broström Procedure in Patients With Generalized Joint Laxity. Orthop J Sports Med 2024; 12:23259671241229443. [PMID: 38455150 PMCID: PMC10919140 DOI: 10.1177/23259671241229443] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/15/2023] [Accepted: 08/21/2023] [Indexed: 03/09/2024] Open
Abstract
Background Generalized joint laxity (GJL) is a risk factor for inferior outcomes after the modified Broström procedure for chronic lateral ankle instability, while anatomic reconstruction with tendons is more inclined to be recommended. However, whether anatomic reconstruction could achieve better results than the modified Broström procedure in patients with GJL is unknown. Purpose To compare clinical outcomes and return to sports between anatomic reconstruction and the modified Broström procedure in patients with GJL. Study Design Cohort study; Level of evidence, 3. Methods Patients with GJL (Beighton score ≥4) who underwent either the modified Broström procedure or anatomic reconstruction with gracilis autografts between 2017 and 2020 were reviewed. Included were 19 patients who underwent anatomic reconstruction (reconstruction group) and 49 patients who underwent the modified Broström procedure (MBP group). Clinical outcomes were compared using the Foot and Ankle Outcome Score (FAOS) and the Karlsson score. The rates of return to preinjury level in high-demand sports, sprain recurrence, and range of motion between the 2 groups were also compared. Results The mean follow-up duration was 38.3 months in the reconstruction group and 43.7 months in the MBP group. The FAOS and Karlsson scores improved significantly after surgery in both groups (P < .001 for all), with the reconstruction group having significantly higher postoperative FAOS-Sports scores (87.9 ± 8.9 vs 80.5 ± 11.6; P = .015) and Karlsson scores (86.9 ± 6.1 vs 82 ± 8.4; P = .025) than the MBP group. The rate of return to preinjury high-demand sports was higher in the reconstruction group than in the MBP group (73.3% vs 38.9%; P = .034). The MBP group had a significantly higher rate of sprain recurrence (22.4% vs 0%; P = .027). More patients reported dorsiflexion restriction in the reconstruction group (n = 4; 21.1%) than in the MBP group (n = 1; 2%) (P = .019); nonetheless, there was no noticeable effect on daily life and sports. Conclusion Better clinical outcomes, less sprain recurrence, and a higher rate of return to preinjury high-demand sports were found after anatomic reconstruction with free tendons compared with the modified Broström procedure in patients with GJL. Anatomic tendon reconstruction can be recommended for such patients, especially those participating in high-demand sports.

Abstract
It is important to eliminate instability related to chronic lateral ankle instability (CLAI) to prevent osteoarthritis progression. We performed arthroscopic anterior talofibular ligament (ATFL) repair and performed calcaneofibular ligament (CFL) repair if instability remained. This study aimed to assess the clinical outcomes of our arthroscopic procedure compared to that of open surgery. Forty ankles underwent arthroscopic surgery and 23 ankles underwent open surgery to repair the lateral ankle ligaments for CLAI. In the arthroscopic surgery, varus stress was applied under fluoroscopy after ATFL repair, and CFL repair was performed if instability remained. Open surgery was performed using the Broström procedure with ATFL and CFL repair. To assess clinical outcomes, American Orthopaedic Foot & Ankle Society (AOFAS) and Karlsson-Peterson (KP) scores were collected preoperatively and at the final follow-up. The talar tilt angle (TTA) was measured preoperatively and 1 year postoperatively. The arthroscopic group showed significantly higher AOFAS and KP scores at the final follow-up compared to the open surgery group. There was no significant difference in TTA at 1 year between the groups. In open surgery, 2 patients required revision surgery. There were no major complications, but scar-related pain in 2 cases of open surgery was reported. Arthroscopic ATFL repair with the CFL repair gave satisfactory clinical outcomes compared to open surgery in CLAI because of low invasive to soft tissue including the joint capsule. It is important to minimize soft tissue dissection in repairing the lateral ankle ligament in patients with CLAI.

Abstract
BACKGROUND When lateral ankle sprains progress into chronic lateral ankle instability (CLAI), restoring precise anatomic relationships of the lateral ankle ligament complex (LALC) surgically is complex. This study quantifies the radiographic relationships between the anterior talofibular ligament (ATFL), calcaneofibular ligament (CFL), and prominent osseous landmarks visible under fluoroscopy to assist in perioperative practices for minimally invasive surgery for CLAI. METHODS Ten fresh frozen ankle specimens were dissected to expose the LALC and prepared by threading a radiopaque filament through the ligamentous footprints of the ATFL and CFL. Fluoroscopic images were digitally analyzed to define dimensional characteristics of the ATFL and CFL. Directional measurements of the ligamentous footprints relative to the lateral process of the talus and the apex of the posterior facet of the calcaneus were calculated. RESULTS Dimensional measurements of the ATFL were a mean length of 9.3 mm, fibular footprint of 9.4 mm, and talar footprint of 9.1 mm. Dimensional measurements of the CFL were a mean length of 19.4 mm, fibular footprint of 8.2 mm, and calcaneal footprint of 7.3 mm. From the radiographic apparent tip of the lateral process of the talus, the fibular attachment of the ATFL was found 13.3 mm superior and 4.4 mm posterior, whereas the talar attachment was found 11.5 mm superior and 4.8 mm anterior. From the radiographic apparent posterior apex of the posterior facet of the calcaneus, the fibular attachment of the CFL was found 0.2 mm inferior and 6.8 mm anterior, whereas the calcaneal attachment was found 14.3 mm inferior and 5.9 mm posterior. CONCLUSION The ATFL and CFL were radiographically analyzed using radiopaque filaments to outline the ligamentous footprints in their native locations. These ligaments were also localized with reference to 2 prominent osseous landmarks. These findings may assist in perioperative practices for keyhole incision placement and arthroscopic guidance. Perfect lateral ankle joint imaging with talar domes superimposed is required to be able to do this. CLINICAL RELEVANCE Radiographic evaluation of the ATFL and CFL with reference to prominent osseous landmarks identified under fluoroscopy may assist in perioperative practices for minimally invasive surgery to address CLAI for keyhole incision placement and arthroscopic guidance.

Abstract
PURPOSE To observe the clinical efficacy and safety of arthroscopic-modified Broström surgery for the treatment of anterior talofibular ligament injury. METHODS The clinical data of 51 cases with anterior talofibular ligament injury were retrospectively analyzed, in which 23 patients were treated by arthroscopic-modified Broström surgery (arthroscopic surgery group) and 28 patients were treated by open-modified Broström surgery (open surgery group). The time to surgery, hospital stay, visual analog scale (VAS) scores of ankle pain, American Orthopaedic Foot and Ankle Society (AOFAS) ankle and hindfoot scores, and incidence rate of complications were compared between the two groups. RESULTS (1) General results: compared with open surgery group, arthroscopic surgery group had shorter time to surgery and hospital stay ((33.8 ± 6.7) min, (42.1 ± 8.5) min, t = 1.468, P = 0.001; (2.2 ± 1.4) d, (5.8 ± 1.6) d, t = 1.975, P = 1.975, P = 0.002). (2) VAS scores of ankle pain: there was an interaction effect between the time and group factors (F = 0.378, P = 0.018); overall, there was no statistically significant difference in VAS scores of ankle pain between the two groups, i.e., there was no grouping effect (F = 1.865, P = 0.163); there was statistically significant difference in VAS score of ankle pain at different time points before and after operation, i.e., there was a time effect (F = 1.675, P = 0.000); the VAS scores of ankle pain showed a decreasing trend with time in both groups, but the decreasing trend was not completely consistent between the two groups ((7.78 ± 1.23), (1.23 ± 1.24), (1.03 ± 0.35), (1.01 ± 0.28), F = 0.568, P = 0.000. (7.45 ± 1.43), (1.45 ± 1.87), (1.23 ± 0.55), (1.04 ± 0.37), F = 1.358, P = 0.000); there was no statistically significant difference in VAS score of ankle joint pain between the two groups six and 12 months before and after surgery (t = 2.987, P = 0.055; t = 1.654, P = 2.542; t = 0.015, P = 0.078); the VAS scores of ankle pain in the arthroscopic surgery group was lower than that in the open surgery group three months after operation (t = 1.267, P = 0.023). (3) AOFAS ankle and hindfoot scores: there was an interaction effect between time and grouping factors (F = 2.693, P = 0.027); overall, there was no statistically significant difference in the AOFAS ankle and hindfoot scores between the two groups, i.e., there was no grouping effect (F = 1.983, P = 0.106); there was statistically significant difference in the AOFAS ankle and hindfoot scores at different time points before and after surgery, i.e., there was a time effect (F = 34.623, P = 0.000); the AOFAS ankle and hindfoot scores of the two groups showed an increasing trend with time, but the increasing trend of the two groups was not completely consistent ((48.19 ± 12.89), (89.20 ± 8.96), (90.24 ± 7.89), (91.34 ± 9.67), F = 25.623, P = 0.000; (49.35 ± 13.28), (86.78 ± 12.34), (88.78 ± 9.78),(91.43 ± 7.98), F = 33.275, P = 0.000); there was no statistically significant difference in the AOFAS ankle and hindfoot scores between the two groups 12 months before/after surgery (t = 2.145,P = 0.056;t = 2.879,P = 0.389); compared with open surgery group, the arthroscopic surgery group had higher AOFAS ankle and hindfoot scores 3/6 months after surgery (t = 1.346, P = 0.014; t = 1.874, P = 0.028). CONCLUSION For the treatment of anterior talofibular ligament injury, arthroscopic surgery group is superior to open surgery group in ankle pain relief and functional recovery and has shorter operation time and hospital stay compared with open surgery group.

A Review of Chronic Lateral Ankle Instability and Emerging Alternative Outcome Monitoring Tools in Patients following Ankle Ligament Reconstruction Surgery. J Clin Med 2024; 13:442.

Abstract
Ankle sprains are exceedingly common injuries in both athletes and the general population. They account for 10 to 30% of all sports injuries. Although the vast majority of lateral ankle ligament injuries respond successfully to conservative management, the absolute number of those that progress to chronic lateral ankle instability (CLAI) remains considerably important. This condition is characterized by persistent symptoms and may be associated with short-term and long-term complications and functional deficits. There is still a lack of ideal postoperative management of CLAI patients. Furthermore, an evidence-based rehabilitation phasing does not exist and most of the published studies regarding this subject suggest some protocols based on a wide variety of functional assessment scores and other modalities that are not accurate enough. Moreover, the literature that assesses the ability to return to work (RTW) and return to sport (RTS) in the general population and athletes operated for CLAI most commonly shows aggregated results with global rates of RTW or RTS without describing a detailed timeline based on the readiness of patients to return to each level of activity. Although stress radiographs and MRI have been assessed as potential tools to improve postoperative management of CLAI patients, the first modality is limited by its low sensitivity to detect laxity and the second one by its static character and its inability to predict neither the healing process phase nor the mechanical properties of the repaired/reconstructed ligaments. Bioelectrical impedance, mechanical impedance and near-infrared spectroscopy are non-invasive methods of measurement that could be potential assessment tools to help surgeons improve the postoperative management of patients after CLAI surgery.

Abstract
Lateral ankle sprain is a common injury with a substantial negative impact on physical function, quality of life and health economic burden. Chronic lateral ankle instability (CLAI) as a sequela of lateral ankle sprain can lead to the development of posttraumatic ankle osteoarthritis in the long term. In this article, we explore the epidemiology, burden and definition of CLAI for the appropriate clinical assessment and imaging evaluation of patients with lateral ankle sprain and CLAI. Following that, recent advances and evidence on management of CLAI is critically distilled and summarized.

Prevalence and Injury Patterns of CFL Injury in Chronic Lateral Ankle Instability: An Observational Cross-Sectional Study Using Ultrasound. J Foot Ankle Surg 2024; 63:27-32. [PMID: 37597584 DOI: 10.1053/j.jfas.2023.08.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/10/2021] [Revised: 05/18/2023] [Accepted: 08/13/2023] [Indexed: 08/21/2023]
Abstract
The purpose of this paper is to assess the prevalence and injury patterns of the calcaneofibular ligament (CFL) in chronic lateral ankle instability (CAI) patients using ultrasound imaging. This retrospective study included 938 ankle ultrasound images from January 2016 to May 2018. The patients' demographic data and the injury pattern classified by the injury location and the remnant quality were recorded and correlated using t tests, Fisher's exact tests, and post hoc tests accordingly. Of the 938 CAI patients, CFL injury was found in 408/938 (44%). Among the 408 anterior talofibular ligament (ATFL) and CFL complex injury patients, 71/408 (17%) presented with a completely absorbed ATFL, whereas 13/71 (18%) presented with an absorbed CFL. The total CFL absorption proportion in all patients was relatively low (30/938 = 3%). Post hoc tests indicated a negative association between thickened ATFLs and complex injuries. In addition, a positive association existed between absorbed ATFLs and complex injuries as well as absorbed ATFLs and absorbed CFLs. Thus, the results indicated that total tearing and absorption injury patterns of the CFL in CAI are not common. Even when the ATFL is absorbed, only approximately one-fifth (13/71 = 18%) of CFLs require reconstruction, suggesting that it is unnecessary to routinely repair or reconstruct CFLs in all lateral ligament surgeries.

Five-year clinical follow-up of arthroscopically treated chronic ankle instability. Orthop Traumatol Surg Res 2023; 109:103649. [PMID: 37364821 DOI: 10.1016/j.otsr.2023.103649] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/05/2022] [Revised: 03/27/2023] [Accepted: 04/14/2023] [Indexed: 06/28/2023]
Abstract
INTRODUCTION Arthroscopic treatment of lateral ankle instability is a recent innovation. In 2014, a prospective study was initiated by the French Society of Arthroscopy demonstrating the feasibility, morbidity and short-term results of arthroscopic treatment of ankle instability. HYPOTHESIS The functional results of arthroscopic treatment of chronic ankle instability found after one year were maintained in the medium term. MATERIAL AND METHODS The prospective follow-up of the patients included in the initial cohort was continued. The Karlsson and AOFAS scores, as well as patient satisfaction, were assessed. The causes of failure underwent univariate and multivariate analyzes. The results of 172 patients were included (40.2% ligament repairs; 59.7% ligament reconstructions). The average follow-up was 5years. The average satisfaction was 8.6/10, the average Karlsson score was 85 points and the average AOFAS score was 87.5 points. The reoperation rate was 6.4% of patients. The failures were related to an absence of sports practice, a high BMI and female gender. A high BMI and the intense sports practice were associated to ligament repair failure. The absence of sports practice and the intraoperative presence of the anterior talofibular ligament were associated to ligament reconstruction failure. DISCUSSION Arthroscopic treatment of ankle instability confers high satisfaction in the medium term, as well as long-lasting results with a low reoperation rate. A more detailed evaluation of the failure criteria could help guide the choice of treatment between ligament reconstruction or repair. LEVEL OF EVIDENCE II.

MRI signal intensity ratio reflects the quality of the anterior talofibular and calcaneofibular ligaments in patients with chronic lateral ankle instability. J Orthop Sci 2023; 28:1331-1336. [PMID: 36336638 DOI: 10.1016/j.jos.2022.10.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/15/2022] [Revised: 09/16/2022] [Accepted: 10/16/2022] [Indexed: 11/06/2022]
Abstract
BACKGROUND Ligament quality can affect clinical outcomes of ligament repair in chronic lateral ankle instability (CLAI). Magnetic resonance imaging (MRI) is used to assess the morphological changes of ligaments, but the measurement of signal intensity enables quantitative evaluation, which can evaluate the degree of the ligament quality. This study aimed to evaluate the qualitative diagnostic capacity for anterior talofibular ligament (ATFL) and calcaneofibular ligament (CFL) injuries of the signal intensity on MRI. METHODS Thirty-eight and 20 ankles with and without CLAI, respectively, were included. The regions of interest (ROIs) were set in the ATFL, CFL, and tibialis anterior tendon (TAT) on MRI, and the signal intensities were measured. The signal intensities of the ATFL and CFL were corrected using TAT as the signal intensity ratio (SIR). The SIRs of the ATFL and CFL in the control and CLAI groups were compared. The relationship between the SIR of the ATFL and the arthroscopic findings was analyzed. Finally, the SIRs of the CFL in CLAI with and without CFL repair were compared. RESULTS The mean SIR of the ATFL in the CLAI group (6.1 ± 2.4) was significantly higher than that in the control (2.1 ± 0.4) (P < 0.01). The SIR of the ATFL was associated with the arthroscopic grading. The mean SIR of the CFL in the CLAI groups (4.1 ± 2.5) was significantly higher than that in the control (1.7 ± 0.4) (P < 0.01). The SIR of the CFL in patients with the requirement of the CFL repair (6.2 ± 1.9) was significantly higher than that without the CFL repair (2.1 ± 0.5) (P < 0.05). CONCLUSIONS The SIR is useful for evaluating the quality of the ATFL and CFL, which enables the decision of the treatment strategy of the CLAI.

High body mass index is not a contraindication for an arthroscopic ligament repair with biological augmentation in case of chronic ankle instability. Knee Surg Sports Traumatol Arthrosc 2023; 31:5222-5227. [PMID: 37713126 DOI: 10.1007/s00167-023-07557-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/28/2023] [Accepted: 08/29/2023] [Indexed: 09/16/2023]
Abstract
PURPOSE Obesity remains frequently mentioned as a contraindication for lateral ankle ligament repair. The aim of the study was to compare the clinical results of an arthroscopic lateral ligament repair with biological augmentation between patients with a body mass index (BMI) of more than 30 and less than 30. METHODS Sixty-nine patients with an isolated lateral ankle instability were treated with an arthroscopic anterior talofibular ligament (ATFL) repair with biological augmentation using the inferior extensor retinaculum (IER). Patients were divided into two groups according to their BMI: ≥ 30 (Group A; n = 26) and < 30 (Group B; n = 43). Patients were pre-and post-operatively evaluated, with a minimum of 2 years follow-up, and using the Karlsson Score. Characteristics of the patients, complications, ankle instability symptoms recurrence, and satisfaction score were recorded. RESULTS In group A, the median Karlsson Score increased from 43.5 (Range 22-72) to 85 (Range 37-100) at follow-up. Complications were observed in seven patients (27%). Nineteen patients (73%) reported that they were "very satisfied". One patient (4%) described persistent ankle instability symptoms. In group B, the median Karlsson Score increased from 65 (Range 42-80) to 95 (Range 50-100) at follow-up. Complications were observed in four patients (9%). Thirty-three patients (77%) reported that they were "very satisfied". Two patients (5%) described persistent ankle instability symptoms. Pre-operative and at last follow-up Karlsson Score, results were significantly different between the two groups. There was no significant statistical difference in favour of satisfaction score, complications and recurrence of ankle instability between the two groups. CONCLUSION ATFL repair with biological augmentation using IER gives excellent results for patients with BMI ≥ 30. Compared to patients with BMI < 30, they present a slightly lower preoperative and postoperative Karlsson score, however, with a similar satisfaction rate, but are at higher risk of transient superficial peroneal nerve dysesthesia.

A new method of anterior talofibular ligament reconstruction: Arthroscopically artificial ligament reconstruction with tensional remnant-repair. Chin J Traumatol 2023; 26:317-322. [PMID: 37926628 PMCID: PMC10755778 DOI: 10.1016/j.cjtee.2023.10.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/24/2023] [Revised: 09/30/2023] [Accepted: 10/20/2023] [Indexed: 11/07/2023] Open
Abstract
PURPOSE To investigate the clinical effects of arthroscopically artificial ligament reconstruction with tensional remnant-repair in patients who are obese, and/or with demand for highly intensive sports, and/or with poor-quality ligament remnants. METHODS A retrospective case series study was performed on patients treated by arthroscopically anterior talofibular ligament (ATFL) reconstruction with tensional remnant repair technique from January 2019 to August 2021. General data, including demographics, surgical time, and postoperative adverse events, were recorded. The American Orthopaedic Foot and Ankle Society score (AOFAS), foot and ankle ability measure (FAAM), visual analog scale (VAS), and anterior talar translation were measured preoperatively and at 6 weeks, 3 months, and 2 years postoperatively. Ultrasonography examination was performed preoperatively and 2 years postoperatively to evaluate the ATFL. Data were analyzed using SPSS 19.0. F test was used to analyze the pre- and postoperative VAS, FAAM, and AOFAS scores. The significance was set at p < 0.05. RESULTS There were 20 males and 10 females among the patients with a mean age of (30.71 ± 5.81) years. The average surgical time was (40.21 ± 8.59) min. No adverse events were observed after surgery. At 2 years postoperatively, the anterior talar translation test showed grade 0 laxity in all patients. VAS score significantly decreased from preoperatively to 6 weeks, 3 months, and 2 years postoperatively (p < 0.001). Improvement of FAAM score and the AOFAS score from preoperatively to 6 weeks, 3 months, and 2 years postoperatively was statistically significant (p < 0.001). At 3 months postoperatively, most patients (23/30) could return to their pre-injured activities of daily living status. At 2 years postoperatively, all patients were able to return to their pre-injured activities of daily living status, and almost every patient (18/19) who expected highly intensive sports returned to sports with only 1 obese patient failing to achieve the goal. The ultrasonography examination at 2 years postoperatively showed that there was a linear band structure of soft tissue on the tension-rich fiber tape image from the fibular to the talar attachment sits of ATFL. CONCLUSION The novel arthroscopically artificial ligament reconstruction with tensional remnant-repair technique for ATFL achieved satisfactory clinical outcomes in the short and medium term after operation, and allowed early return to pre-injured activities, which could be a reliable option for patients with chronic lateral ankle instability.

Chronic Ankle Instability - Mechanical vs. Functional. ZEITSCHRIFT FUR ORTHOPADIE UND UNFALLCHIRURGIE 2023; 161:552-562.

Abstract
Chronic ankle instability arises from three interacting contributing factors: mechanical ankle instability, functional ankle instability, and perceived ankle instability. To decide on the most appropriate individual recommendation for therapeutic options, it is necessary to assess which of the two main aetiologies - functional vs. mechanical - is dominant in causing the perceived impairment. It is essential to perform a thorough analysis and diagnosis, even though quantifying mechanical ankle instability is still a challenge in the clinical approach to this common pathology. When diagnosing mechanical instability, the most established procedure is physical examination, although this unfortunately does not allow the deficit to be quantified. Additional options include stress-ultrasound, 3D stress-MRI (3SAM), ankle arthrometry, marker-based 3D motion analysis, and diagnostic ankle arthroscopy. Of these the latter is considered the gold standard, even though it is an invasive procedure, it may not be performed for diagnostic reasons only, and it also does not allow the mechanical instability to be quantified. For diagnosing functional instability there are non-instrumented tests such as the Star Excursion Balance Test or Y-Balance Test, posturography/stabilometry, and gait and running analysis, possibly combined with EMG acquisition and isokinetic strength testing.To date, the standard of care is conservative management of ankle instability, and the therapy should include sensorimotor training, strength training of the periarticular muscles, balance training, and gait and running exercises on different surfaces. However, it is increasingly clear that a certain degree of mechanical instability cannot be compensated for by functional training. Thus, it is the goal of differential diagnostics to identify those patients and guide them to mechanical therapy, including ankle bracing, taping, and surgical ligament reconstruction.

Abstract
PURPOSE The literature on elite athletes' ability to return to sports (RTS) after early lateral ligament repair of the ankle remains inadequate. The time needed to RTS after modified Broström repair for acute grade III lateral ligament injuries in a large cohort of elite athletes was evaluated while assessing the impact of other associated injuries. METHODS Prospective data from 147 elite athletes who underwent a primary lateral ligament repair for acute grade III injuries with clinical ankle instability from 2015 to 2019 with a minimum of 2-year follow-up were reviewed. Pertinent details such as characteristics of injury, time taken to RTS, impact of associated injuries on RTS and complications were recorded and analysed. RESULTS The average age was 24.4 years (S.D = 4.9) with 89.1% males. Approximately two-thirds of the elite athletes were football players (66.0%) and 21.1% were rugby players. Isolated lateral ligament complex injuries were sustained by 122 (83%) patients, while 25 (17%) had associated injuries (osteochondral lesions of the talus/deltoid injury/syndesmosis injury). All 147 athletes returned to their preinjury level of sports with a median time of 69 days (range 58-132 days). There was no significant difference found in time to RTS between gender, age, and types of sports. However, there was a statistically significant difference noted in the time taken to RTS earlier in patients with isolated lateral ligament injuries when compared to those with associated injuries (68.6 vs. 82.8 days; p = 0.004). Multiple conditional linear regression yielded three independent predictors of longer time taken to RTS which were associated deltoid injury (7.5 days longer; 95% CI 2.9-12.3; p = 0.002), associated syndesmosis injury (6.7 days longer; 95% CI 0.5-12.8; p = 0.034) and associated OLT (30.3 days longer; 95% CI 25.1-35.5; p = 0.000). CONCLUSION Early surgical repair for acute grade III lateral ligament injuries in elite athletes yielded excellent rate of RTS at 9-10 weeks and a re-injury rate of 2%. Concomitant injuries will delay RTS after surgical intervention. These findings serve as important guide to managing elite athletes following acute rupture of the lateral ligament complex.

Optimal fibular tunnel direction for anterior talofibular ligament reconstruction: 45 degrees outperforms 30 and 60 degrees. Knee Surg Sports Traumatol Arthrosc 2023; 31:4546-4550. [PMID: 37308663 DOI: 10.1007/s00167-023-07452-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/22/2023] [Accepted: 05/02/2023] [Indexed: 06/14/2023]
Abstract
PURPOSE There is currently no consensus on the optimal drilling direction of the fibular bone tunnel for anterior talofibular ligament (ATFL) reconstruction, and few studies have investigated the potential injury to the peroneus longus and brevis tendons and the possibility of fibular fractures during the drilling process. The aim of this study was to assess the potential risk of drilling the tunnel from different directions and determine the most appropriate tunnel direction. The hypothesis was that drilling the tunnel in the 45-degree direction would be the safest and most suitable for the fibular tunnel. METHODS Forty-eight fibular tunnels were drilled on fresh ankle specimens using a K-wire guide and a 5.0 mm hollow drill. Three tunnel orientations were created, parallel to the sagittal plane of the long axis of the fibula and angled 30°, 45°, and 60° to the coronal plane. The length of the fibular tunnel and the distances from the outlet of the K-wire to the peroneus longus and brevis tendons were measured. The occurrence of a fibula fracture was also observed. RESULTS The lengths of the bone tunnels in the three groups were 32.9 ± 6.1 mm (30°), 27.2 ± 4.4 mm (45°) and 23.6 ± 4.0 mm (60°). The length of the tunnel drilled at 30° was the longest when compared with that of the tunnels drilled at 45° and 60° (all p values < 0.05). The distances from the outlet of the K-wire to the peroneus longus tendon were 3.0 ± 3.8 mm (30°), 3.8 ± 3.2 mm (45°) and 5.3 ± 1.8 mm (60°), and the distances to the peroneus brevis tendon were 4.2 ± 4.0 mm (30°), 6.1 ± 3.8 mm (45°), 7.9 ± 3.5 mm (60°). In terms of protecting the peroneus longus and brevis tendons, drilling in the 60° direction was better than drilling in the 30° and 45° directions (all p values < 0.05). The risk of injury to the peroneal longus and brevis tendons was 62.5% (30°), 31.3% (45°), and 0% (60°). Although no fibular fractures were observed in any of the three directions, drilling the bone tunnel in the 60° direction disrupted the lateral cortex of the fibula. CONCLUSION This study shows that drilling the tunnel in the 45° direction is less likely to cause injury to the peroneus longus and brevis tendons, while ensuring that the tunnel has a sufficient length and avoiding fracturing the distal fibula. Drilling a fibular bone tunnel in a 45° direction is safer and recommended for ATFL reconstruction.

Abstract
BACKGROUND Hindfoot varus deformity is a known risk factor for chronic lateral ankle instability (CLAI). The impact of this deformity on clinical results following arthroscopic lateral ankle ligament repair (ALLR) for CLAI has not been studied. METHODS Sixty-three ankles from 62 patients who received ALLR for CLAI were retrospectively examined. Preoperative plain radiographs were used to measure tibial articular surface (TAS) angles, and long axial hindfoot alignment radiographs were used to measure tibiocalcaneal angles (TCAs) pre- and postoperatively. Results included ratings on the Self-Administered Foot Evaluation Questionnaire (SAFE-Q) and recurrent ankle instability (respraining of the operated ankle following surgery). RESULTS Recurrent ankle instability, defined as incidence of any new ankle sprain after surgery reported in the follow-up period, occurred in 13 ankles. The TAS angles of these patients were significantly low, and their preoperative TCA was significantly high. Multivariate analysis showed that preoperative TCA was an independent risk factor for recurrent ankle instability. The threshold values for preoperative TCA for recurrent instability were determined via the receiver operating characteristic curve analysis to be 3.4 degrees. Patients were assigned to a low- or high-TCA group based on the reported average TCA (2.7 degrees) of healthy patients. In the high-TCA group, recurrent instability was significantly more frequent, and the scores on the pain subscale of the postoperative SAFE-Q were significantly lower. CONCLUSION Hindfoot varus alignment was associated with pooreroutcomes after ALLR. LEVEL OF EVIDENCE Level III, retrospective comparative study.

Abstract
INTRODUCTION Ankle injuries and instability in a pediatric age group are common problems and often underreported. The injuries can range from a relatively benign ankle sprain to pain-limiting ankle instability that can inhibit the child from participating in sporting activities. However, conservative management and physiotherapy are the mainstay of treatment; a small group of patients present with persistent instability and benefit from surgical intervention in lateral ligament reconstruction. Our study looked at pediatric patients who had instability following failed conservative management. METHODS Retrospective analysis of 14 patients with Chronic lateral Ankle instability (CLAI) who underwent Modified Brostrom-Gould repair( MBG) with or without Internal brace augmentation between January 2015 and October 2020. Patients were evaluated for the visual analogue scale (VAS), Manchester-oxford foot questionnaire (MOxFQ), subjective satisfaction, and return to preinjury activity level. RESULTS Pain score improved from 8 (average 5-9) to 1 (average 0-3) following surgery. Functional assessment was made by assessing the Manchester Oxford questionnaire pre-and postoperatively. MOxFQ scores improved from 64 (8 SD) to 7 (15 SD). Thirteen of fourteen patients returned to normal sporting activities at the final follow-up. CONCLUSION Modified Brostrom-Gould with InternalBrace™ augmentation is an excellent procedure for chronic lateral ligament injuries in the Paediatric population. It can be safely performed if we respect the anatomy and the physeal growth plate. It allows faster rehabilitation and return to preinjury activity level.

Abstract
BACKGROUND Arthroscopic anterior talofibular ligament (ATFL) repair is widely performed for chronic lateral ankle instability (CLAI). Although many studies have reported excellent outcomes with this procedure, the recurrence of instability remains a common concern. Therefore, this study aimed to analyze the risk factors for the recurrence of instability after arthroscopic repair for CLAI. METHODS Fifty-six ankles of 53 patients with a mean age of 31.8 ± 14.7 years were retrospectively reviewed. All patients underwent arthroscopic ATFL repair. If instability remained immediately after ATFL repair, calcaneofibular ligament (CFL) repair was performed. The Ankle Activity Score (AAS) was assessed preoperatively, and clinical outcomes including the Japanese Society for Surgery of the Foot scale, Karlsson-Peterson scores, and the Self-Administered Foot Evaluation Questionnaire (SAFE-Q) were evaluated preoperatively and at the final follow-up. Talar tilt angle (TTA) was assessed preoperatively and 1 year postoperatively. Ankles were divided into 2 groups-nonrecurrence (postoperative TTA, <6 degrees) and recurrence (postoperative TTA, ≥6 degrees)-and clinical outcomes were compared. RESULTS Sixteen ankles showed recurrent instability, whereas 40 did not. AAS, TTA, and social functioning in the SAFE-Q were significantly higher in the recurrence group than those in the nonrecurrence group preoperatively. In addition, the rate of poor ATFL remnant quality and the number of CFLs not repaired despite the preoperative injury diagnosis were significantly higher in the recurrence group than in the nonrecurrence group. CONCLUSION Arthroscopic repair for ATFL and CFL deficiencies with preoperative high activity, poor remnant quality, and neglected CFL injury can result in the recurrence of instability. Appropriate surgical procedures to prevent the recurrence of instability should be selected for these ankles. LEVEL OF EVIDENCE Level IV, retrospective case series.

Abstract
Introduction Chronic lateral ankle instability (CLAI) is a known complication of ankle sprains, most commonly involving injury to the anterior talofibular ligament (ATFL). Growing evidence has shown an association between anteromedial (AM) impingement and CLAI. The purpose of this paper is to compare magnetic resonance imaging (MRI) with arthroscopic findings for the incidence of AM impingement in CLAI. Methods A retrospective study was performed by analyzing the radiological and operative reports of all patients who underwent an arthroscopic Broström-Gould procedure for CLAI between 2021 and 2022 at Changi General Hospital, Singapore. All patients who had a pre-operative MRI ankle scan performed and mention of the presence or absence of AM impingement in the operative notes were included in this study. Patients with concomitant fractures or systemic conditions affecting the same ankle were excluded. Results Ninety-seven patients were included in this study, 65 males and 32 females; 6.2% (6 of 97) of patients had a suggestion of AM impingement based on MRI findings, and 77.3% (75 of 97) of patients were noted to have AM impingement based on arthroscopic findings. Conclusion There is a high incidence of AM impingement associated with CLAI. AM impingement is often missed based on MRI findings. Arthroscopic Broström should be considered to address both issues of AM impingement and CLAI in the same setting.

Abstract
The objective was to evaluate the clinical joint and limb measures in professional female soccer players. The study was a cross-sectional observational design. It was a preseason clinical setting. The inclusion criteria were outfield professional female soccer players, based in the UK, competing in the highest English league. The exclusion criteria included players who had had surgery in the last six months or had missed a single training session or match due to injury in the previous three months. In terms of the outcome measures, the dependent variables were the true limb length, ankle dorsiflexion, knee flexion and extension, hip flexion, extension, internal rotation and external rotation, and straight leg raise measured using video analysis software. Additionally, passive clinical knee and ankle stability tests were conducted. The independent variables were leg dominance and playing position (defender, midfielder, and attacker). For the results, all the ROM measurements demonstrated limb symmetry (p = 0.621). However, there were significant main effects of the playing position on the ankle dorsiflexion and hip internal rotation, with defenders demonstrating a significantly reduced range of motion in comparison to midfielders and attackers. A notable finding from the bilateral passive stability measures was that 38.3% of players exhibited ankle talar inversion instability when using a talar tilt. In conclusion, bilateral differences do not appear to be apparent in this population; however, positional differences may occur in the ankle and hip range of motion measures. A high proportion of this population may present with passive ankle inversion instability. Future research should consider whether this leads to a higher risk of injury in this population.

Abstract
Imaging examinations are a fundamental part of assessing chronic lateral ankle instability (CLAI). Plain radiographs are used in the initial examination, whereas stress radiographs can be requested to actively search for instability. Ultrasonography (US) and Magnetic Resonance Imaging (MRI) allow direct visualization of ligamentous structures, with the advantage of dynamic evaluation for US, and assessment of associated lesions and intra-articular abnormalities for MRI, which plays an essential role in surgical planning. This article reviews imaging methods to diagnose and follow up on CLAI, along with illustrative cases and an algorithmic approach.

Abstract
Lateral ankle sprain (LAS) is not as simple as it was believed to be as it has substantial negative impacts on the active sporting population. The negative impact on physical function, quality of life (QoL) and economic burden is significant with increased risk of reinjury, development of chronic lateral ankle instability and posttraumatic ankle osteoarthritis resulting in functional deficits, decreased QoL and chronic disabilities. Economic burden from a societal perspective demonstrated notably higher indirect costs from productivity loss. Preventative interventions with early surgery for a selective cohort of active sporting population may be considered to mitigate morbidities associated with LAS.

Progress in diagnosis and treatment of acute injury to the anterior talofibular ligament. World J Clin Cases 2023; 11:3395-3407. [PMID: 37383912 PMCID: PMC10294195 DOI: 10.12998/wjcc.v11.i15.3395] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/30/2022] [Revised: 03/07/2023] [Accepted: 04/14/2023] [Indexed: 05/25/2023] Open
Abstract
Injury to the anterior talofibular ligament (ATFL) is a common acute injury of the lateral foot ligament. Untimely and improper treatment significantly affects the quality of life and rehabilitation progress of patients. The purpose of this paper is to review the anatomy and the current methods of diagnosis and treatment of acute injury to the ATFL. The clinical manifestations of acute injury to the ATFL include pain, swelling, and dysfunction. At present, non-surgical treatment is the first choice for acute injury of the ATFL. The standard treatment strategy involves the “peace and love” principle. After initial treatment in the acute phase, personalized rehabilitation training programs can be followed. These may involve proprioception training, muscle training, and functional exercise to restore limb coordination and muscle strength. Static stretching and other techniques to loosen joints, acupuncture, moxibustion massage, and other traditional medical treatments can relieve pain, restore range of motion, and prevent joint stiffness. If the non-surgical treatment is not ideal or fails, surgical treatment is feasible. Currently, arthroscopic anatomical repair or anatomical reconstruction surgery is commonly used in clinical practice. Although open Broström surgery provides good results, the modified arthroscopic Broström surgery has many advantages, such as less trauma, rapid pain relief, rapid postoperative recovery, and fewer complications, and is more popular with patients. In general, when treating acute injury to the ATFL, treatment management and methods should be timely and reasonably arranged according to the specific injury scenario and attention should be paid to the timely combination of multiple therapies to achieve the best treatment results.

Abstract
Lateral ankle instability is a common condition which responds well to non-surgical management. However, the chronic symptomatic instability may require surgical intervention. The acceptable and practiced procedure is the Brostom Gould modification and it has a high patient satisfaction score. However, the current understanding and newer techniques for stabilising the lateral ligament complex has resulted in arthroscopic repairs, augmentation and tendon graft reconstructions. The literature does not provide an answer to the efficacy of these new techniques but there is some preliminary information favouring some of the latest procedures. It is now accepted practise to include ankle arthroscopy as a pre repair step. Augmentation of anatomical repair is also favoured in a select group of patients. This article provides an up to date account of the newer techniques for lateral ankle stabilisation.

Role of the intrinsic subtalar ligaments in subtalar instability and consequences for clinical practice. Front Bioeng Biotechnol 2023; 11:1047134. [PMID: 36970618 PMCID: PMC10036586 DOI: 10.3389/fbioe.2023.1047134] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/17/2022] [Accepted: 02/28/2023] [Indexed: 03/12/2023] Open
Abstract
Subtalar instability (STI) is a disabling complication after an acute lateral ankle sprain and remains a challenging problem. The pathophysiology is difficult to understand. Especially the relative contribution of the intrinsic subtalar ligaments in the stability of the subtalar joint is still controversial. Diagnosis is difficult because of the overlapping clinical signs with talocrural instability and the absence of a reliable diagnostic reference test. This often results in misdiagnosis and inappropriate treatment. Recent research offers new insights in the pathophysiology of subtalar instability and the importance of the intrinsic subtalar ligaments. Recent publications clarify the local anatomical and biomechanical characteristics of the subtalar ligaments. The cervical ligament and interosseous talocalcaneal ligament seem to play an important function in the normal kinematics and stability of the subtalar joint. In addition to the calcaneofibular ligament (CFL), these ligaments seem to have an important role in the pathomechanics of subtalar instability (STI). These new insights have an impact on the approach to STI in clinical practice. Diagnosis of STI can be performed be performed by a step-by-step approach to raise the suspicion to STI. This approach consists of clinical signs, abnormalities of the subtalar ligaments on MRI and intraoperative evaluation. Surgical treatment should address all the aspects of the instability and focus on a restoration of the normal anatomical and biomechanical properties. Besides a low threshold to reconstruct the CFL, a reconstruction of the subtalar ligaments should be considered in complex cases of instability. The purpose of this review is to provide a comprehensive update of the current literature focused on the contribution of the different ligaments in the stability of the subtalar joint. This review aims to introduce the more recent findings in the earlier hypotheses on normal kinesiology, pathophysiology and relation with talocrural instability. The consequences of this improved understanding of pathophysiology on patient identification, treatment and future research are described.

Comparison of balance and function in the long term after all arthroscopic ATFL repair surgery. Arch Orthop Trauma Surg 2023:10.1007/s00402-023-04817-x. [PMID: 36811664 DOI: 10.1007/s00402-023-04817-x] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/09/2022] [Accepted: 02/13/2023] [Indexed: 02/24/2023]
Abstract
INTRODUCTION We compared the balance, ROM, clinical scores, kinesiophobia and functional outcomes of patients after all-arthroscopic ATFL repair surgery with the non-operated side and healthy control group. MATERIALS AND METHODS Twenty-five patients with follow up time 37.32 ± 12.51 months and twenty-five healthy controls participated in the study. Postural stability was evaluated with the Biodex® balance system by measuring overall (OSI), anterior-posterior (API), and mediolateral (MLI) stability index. Dynamic balance and function were measured using the Y-balance test (YBT) and single-leg hop test (SLH). Limb symmetry index for SLH and contralateral comparisons (YBT, OSI, API, MLI) was performed. The AOFAS score and the Tampa Scale of Kinesiophobia (TSK) were applied. Two subgroups were created (with OLT and without OLT). RESULTS There was no statistically significant difference between subgroups. There was no statistically significant difference between bilateral OSI, API, MLI values and YBT anterior reach distances of all groups. Single leg OSI (0.78 ± 0.27/0.55 ± 0.12), API (0.55 ± 0.22/0.41 ± 0.10), and MLI (0.40 ± 0.16/ 0.26 ± 0.08) values were significantly worse and YBT posteromedial (73.88 ± 15.70/89.62 ± 12.25), posterolateral reach (78.03 ± 14.08/92.62 ± 8.25) and the SLH distance (117.14 ± 27.84/165.90 ± 20.91) were significantly lower on the patients than controls (p < 0.05), respectively. In contralateral comparisons, all reach distances on YBT were similar and SLH limb symmetry index of the operated side was 98.25%. AOFAS scores of the patients were 92.62 ± 11.13, TSK scores were 46.45 ± 11.32, and 21 patients (84%) had kinesiophobia. CONCLUSION AOFAS score, limb symmetry index, and bilateral balance of the patients were successful; however, there is single-leg postural stability insufficiency and kinesiophobia. Although the extremity symmetry index of the operated side of the patients was 98.25, the fact that these values are lower than those of the healthy control may have been caused by kinesiophobia. During the long-term rehabilitation, kinesiophobia should be considered and single-leg balance exercises should be monitored during the rehabilitation period. LEVEL OF EVIDENCE Level III.

Abstract
OBJECTIVE To introduce the surgical technique and clinical outcomes of arthroscopic anterior talofibular ligament (ATFL) repair using the Internal Brace and lasso-loop technique for chronic ankle lateral instability. METHODS A retrospective study was performed on 29 patients who underwent all-arthroscopic ATFL repair with the Internal Brace and lasso-loop technique from January to August 2020. The patients included 24 males and five females, with a mean age of 30.17 years. Through the accessory anterolateral (AAL) portal, we drilled the bone tunnels and fixed the tape with 4.75 mm and 3.5 mm "SwiveLock" anchors and reattached the torn ligament by the lasso-loop technique. RESULTS All 29 patients underwent all-arthroscopic procedures smoothly without serious complications, such as infection and important nerve or vessel injuries. There were eight cases of lateral malleolar avulsion fractures and ten cases of talus cartilage injury. The visual analog scale (VAS), Karlsson-Peterson, Tegner, and American Orthopedic Foot and Ankle Society (AOFAS) scores were used to evaluate the clinical consequences. All the patients were followed up for 18.66 ± 4.85 months on average. The average pre-operative VAS score was 4.69 ± 1.04, which was significantly higher than the average post-operative VAS score of 1.14 ± 1.56. At the final follow-up appointments, the averages of Karlsson-Peterson, AOFAS, and Tenger scores were 75.83 ± 9.44, 88.31 ± 6.81, and 6.93 ± 1.79, respectively, which was significantly higher than that before the operation. CONCLUSION This arthroscopic anterior talofibular ligament repair with the Internal Brace and lasso-loop technique achieves satisfactory clinical outcomes with the benefits of high safety and reliability for chronic ankle lateral instability.

Abstract
PURPOSE Diagnosis and treatment of subtalar instability (STI) remains complicated and challenging. The purpose of this study was to investigate the outcome of an anatomical reconstruction of the cervical ligament in patients with suspected chronic STI. METHODS This prospective study assessed the results of a surgical reconstruction of the cervical ligament using a gracilis tendon graft in a group of 14 patients (16 feet). Diagnosis of STI was performed using a predefined algorithm including clinical signs, MRI and peroperative evaluation. All patients had symptoms of chronic hindfoot instability despite prolonged non-surgical treatment. At final follow-up the outcome was assessed using the Karlsson score, the Foot and Ankle Outcome Score and the American Orthopaedic Foot and Ankle Society score. RESULTS After an average follow up of 22.6 months (range, 15-36), all patients reported significant improvement compared to their preoperative symptoms. The mean preoperative Karlsson score improved from 36.4 ± 13.5 (median 37, range 10-55) to a mean postoperative Karlsson score was 89.6 ± 8.5 (median 90, range 72-100) (P < 0.0001). The cervical ligament reconstruction was combined with other procedures in 13 cases: calcaneofibular ligament (CFL) reconstruction (3), CFL and anterior talofibular ligament reconstruction (7), bifurcate ligament reconstruction (3). CONCLUSION Anatomical reconstruction of the cervical ligament is a valid technique to treat patients with STI. It is a safe procedure and produces good clinical results with minimal complications. This technique can be considered in more complex cases and can be combined with other procedures according to the specific location of the instability. LEVEL OF EVIDENCE Level III.

Abstract
PURPOSE The aim of this study was to provide an accurate and improved understanding of anterior talofibular ligament (ATFL) anatomy, and to determine the exact positioning and diameter of the bony tunnel during ATFL repair and/or reconstruction surgery. METHOD A total of 58 healthy asymptomatic volunteers were examined, wherein 38 underwent bilateral ankle 3D MRI, and 20 underwent unilateral ankle 3D MRI (10 left and 10 right ankles). Data from a total of 96 MRI datasets were collected. The MRI data from these cases were exported into Mimics to enable reconstruction of 3D ATFL models. The resulting image quality was evaluated using a 5-point subjective scoring system. In addition, the length, width, thickness, and positioning of each ATFL and the area of the ATFL footprints were identified within the 3D model using Mimics and SolidWorks. RESULTS The image quality score was 4.48 ± 0.50. The ATFL formed one (65.6%), two (31.3%), or three (3.1%) bundles forms. The footprint area was 31.25 ± 6.29 mm2 on the fibular side, and 17.48 ± 4.49 mm2 on the talar side. CONCLUSION Thin-slice 3D MRI aids in the reconstruction of the 3D ATFL model, and it provides reference for the accurate anatomy of the area and location of the ATFL. This technology will facilitate diagnosis of ATFL injuries and choice of surgical methods. LEVEL OF EVIDENCE level IV.

Abstract
PURPOSE To evaluate the complication rates, continuous functional outcome scores, and return to play data following bone marrow stimulation (BMS) versus biologics ± BMS for the treatment of osteochondral lesion of the talus (OLT). METHODS A systematic review was performed. The PubMed and Embase databases were searched using specific search terms and eligibility criteria according to the PRISMA guidelines. The level of evidence was assessed using published criteria by The Journal of Bone & Joint Surgery, and the quality of evidence using the Modified Coleman Methodology Score. Continuous variables were presented as mean ± standard deviation and categorical variables as frequencies (percentages). RESULTS BMS versus BMS + hyaluronic acid (HA): no complications in either treatment arm were reported. The mean American Orthopaedic Foot and Ankle Society score was 43.5 to 67.3 points and 44.0 to 72.4 points, respectively. The mean 10 mm Visual Analogue Scale pain score was 7.7 to 3.8 points and 7.5 to 2.5 points, respectively. BMS versus BMS + concentrated bone marrow aspirate (CBMA): the pooled overall complication rate was 17/64 (26.6%) versus 11/71 (15.5%), respectively (non-significant). The pool revision rate was 15/64 (23.4%) versus 6/71 (8.5%), respectively (p = 0.016). There has been a notable poor reporting of complication rates for the use of ADSC and PRP as adjuvant biological therapies to BMS for the treatment of OLT. CONCLUSION There was an overall limited comparative clinical evidence of adjuvant biologics with BMS versus BMS alone for the treatment of OLT. BMS + HA and BMS + CBMA can provide superior outcomes, albeit the currently limited evidence. Further studies are warranted to establish the true clinical superiority of the various biologics ± BMS versus BMS alone. These studies must also compare the various biologics against one another to determine, if any, the optimal biologic for OLT. Clinicians should counsel patients accordingly on these findings as required. LEVEL OF EVIDENCE Level III.

Anterior talofibular ligament remnant quality is important for achieving a stable ankle after arthroscopic lateral ankle ligament repair. Knee Surg Sports Traumatol Arthrosc 2022; 31:2183-2191.

Abstract
PURPOSE The relationship between ligament remnant quality and postoperative outcomes after arthroscopic lateral ankle ligament repair for chronic lateral ankle instability is controversial. This study aimed to determine whether the signal intensity of the anterior talofibular ligament on preoperative magnetic resonance imaging and ligament remnant quality identified on arthroscopy are associated with recurrent ankle instability after arthroscopic lateral ankle ligament repair. METHODS A total of 68 ankles from 67 patients with chronic lateral ankle instability who underwent arthroscopic lateral ankle ligament repair were retrospectively studied. The signal intensity of the anterior talofibular ligament was evaluated using T2-weighted magnetic resonance imaging. Arthroscopy was used to evaluate the thickness and mechanical resistance of the anterior talofibular ligament by hook palpation and to classify ankles into two groups: the present anterior talofibular ligament group with adequate mechanical resistance and the absent anterior talofibular ligament group with no mechanical resistance. The outcomes included recurrent ankle instability (respraining of the operated ankle after surgery) and Self-Administered Foot Evaluation Questionnaire scores. RESULTS Thirteen ankles were diagnosed with recurrent ankle instability. Patients with a high anterior talofibular ligament T2 signal intensity experienced more recurrent ankle instability than those with a low intensity. As determined via arthroscopy, the absent anterior talofibular ligament group had a higher rate of recurrent ankle instability than the present anterior talofibular ligament group. There were no significant differences in Self-Administered Foot Evaluation Questionnaire scores between patients with high and low anterior talofibular ligament T2 signal intensity, as well as between absent and present anterior talofibular ligament groups based on arthroscopy. CONCLUSION Poor quality of the anterior talofibular ligament remnant could result in recurrent ankle instability after arthroscopic lateral ankle ligament repair. Therefore, when treating chronic lateral ankle instability, surgeons should consider ligament quality. LEVEL OF EVIDENCE IV.

Abstract
PURPOSE Treatment of chronic lateral ankle instability (CLAI) with poor remnant quality is challenging. The aim of the present study was to evaluate clinical results and complications of anatomic reconstruction of the lateral ligaments using allograft tendon and suspensory fixation in the treatment of such patients. METHODS One hundred and eight patients with CLAI, who were treated surgically using anatomic reconstruction with allograft tendon and suspensory fixation between April 2016 and January 2018 at our hospital, were retrospectively analysed. None of the patients had sufficient ligament remnants for the modified Broström procedure during the intraoperative evaluation. Eighteen patients were excluded. Seventeen patients were lost to follow-up and 73 patients completed the study. The mean duration of instability symptoms was 39.1 months (range, 6-480 months). The mean follow-up time was 57.5 months (range, 48-69 months). Clinical results were evaluated using the Karlsson scoring scale, American Orthopaedic Foot and Ankle Society-Ankle and Hindfoot (AOFAS-AH) score, visual analogue scale (VAS), patients' subjective satisfaction, and incidence of complications. Mechanical stability was evaluated using the varus talar tilt angle (TTA) and anterior talar displacement (ATD). RESULTS The AOFAS-AH scores significantly improved from 67.7 ± 8.5 points to 89.8 ± 9.5 (p < 0.001). The Karlsson scoring scales evolved from 58.8 ± 16.5 to 88.4 ± 11.2 (p < 0.001). VAS scores significantly decreased from 2.9 ± 1.3 to 1.1 ± 1.0 (p < 0.001). On stress radiographs, TTA decreased from 15.1 ± 2.5 degrees to 5.8 ± 2.1 degrees (p < 0.001), whereas ATD reduced from 13.4 ± 2.9 mm to 5.7 ± 1.5 mm (p < 0.001). Patients' subjective satisfaction indicated 46 excellent, 20 good, 5 fair, and 2 bad results. Postoperatively, 15 cases (20.5%) did not achieve complete relief of discomfort or swelling, 9 cases (12.3%) experienced joint stiffness or decreased range of motion, and 6 cases (8.2%) had soft tissue irritation. Residual instability and reoperation are rare. Allograft rejection or wound infection was not observed. CONCLUSION For the CLAI patients with poor remnant quality, anatomic reconstruction of the lateral ligaments using allograft tendon and suspensory fixation is an effective procedure, while the top three complications in incidence were residual discomfort, joint stiffness, and soft tissue irritation.

Open Evaluation of the Peroneal Tendons Should Be Considered in Patients With Chronic Lateral Ankle Instability Undergoing Ankle Arthroscopy With Lateral Ankle Stabilization.

Abstract
Peroneal tendon pathology is commonly associated with chronic lateral ankle instability. Foot and ankle surgeons often rely on preoperative magnetic resonance imaging (MRI) for identification of related pathology and surgical planning in these patients. The purpose of this study was to assess the ability of preoperative MRI to accurately detect peroneal tendon pathology in patients with chronic lateral ankle instability. Consecutive surgical cases involving arthroscopic evaluation and management of lateral ankle instability sequelae were evaluated retrospectively. Preoperative MRI were compared to intraoperative findings in order to determine the sensitivity, specificity, positive and negative predictive values. Eighty-two patients met inclusion criteria, 58 females and 24 males. The average age at the time of surgery was 46 years (range 13-75). Peroneal tendon pathology was identified intraoperatively in 76 (92.7%) patients and on MRI in 40 (48.8%) patients. The most commonly identified pathologies were tenosynovitis, tendinopathy and longitudinal split/tear, with the peroneus brevis tendon being most commonly involved. MRI was 38.7% specific, 50.0% sensitive, had a positive predictive value of 92.5%, and a negative predictive value of 7.1%. While MRI is a helpful study for evaluation of co-pathologies and surgical planning in patients with lateral ankle instability, procedural selection should not be solely based on MRI results, and the peroneal tendons should be evaluated intraoperatively in patients undergoing arthroscopic procedures for lateral ankle instability.

Abstract
BACKGROUND Arthroscopic surgery for treating ankle instability is increasingly popular. Several studies showed similar functional outcomes to those seen after open surgery, with no increase in complications. The objective of this study was to evaluate the return-to-sports (RTS) rate and time after arthroscopic surgery to treat chronic lateral ankle instability. HYPOTHESIS The rate and time of RTS are satisfactory after arthroscopic surgery to treat chronic lateral ankle instability. MATERIAL AND METHODS This single-centre retrospective study included patients managed arthroscopically for chronic lateral ankle instability, with no other procedures, between February 2014 and May 2017. We evaluated the time and rate of RTS, as well as factors associated with RTS such as motivation, athletic level before surgery and whether the injury was work-related. Follow-up was at least 1 year. RESULTS Of the 40 included patients, 30 (75%) returned to their main sport, after a median of 6 months. Moreover, 22 (55%) patients resumed their main sport at the same or a higher level within 12 months after surgery, their median postoperative follow-up being 29 months (range, 13-61). The AOFAS score improved significantly, from 67 (30-90) before surgery to 88.5 (39-100) at last follow-up (p<0.001). The numerical pain score decreased significantly between these two timepoints, from 6 (0-10) to 1 (0-10) (p<0.001). By multivariate analysis, a high level of motivation before surgery was the main factor significantly associated with RTS at the same or a higher level within 12 months after surgery (odds ratio, 16.47; 95%CI, 3.33-81.20; p=0.007). Persistent pain was more common in patients with work-related injuries (p=0.016). CONCLUSION At 12 months, the RTS rate was 75% overall, with 55% of patients returning to the same or a higher level. Median time to RTS was 6 months (4-8). Both the rate of and the time to RTS were independently associated with greater preoperative motivation. LEVEL OF EVIDENCE IV, retrospective observational cohort study.

Arthroscopic lateral ankle ligament reinsertion with reinforcement by a minimally invasive extensor retinaculum flap for chronic ankle instability. Orthop Traumatol Surg Res 2022; 108:103303. [PMID: 35477041 DOI: 10.1016/j.otsr.2022.103303] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/16/2020] [Revised: 07/30/2021] [Accepted: 08/04/2021] [Indexed: 02/03/2023]
Abstract
The past decade has seen the development of numerous arthroscopic techniques for ankle ligament repair or reconstruction in the treatment of chronic lateral ankle instability. Arthroscopy allows the assessment and treatment of intra-articular pathologies and is associated with faster functional recovery. The open surgery technique described by Blanchet, combining reinsertion of the lateral collateral ligament with reinforcement by an extensor retinaculum flap, has long proven its effectiveness. The aim of this article is to describe this technique under arthroscopy.

Chronic Lateral Ankle Instability Treated With Tendon Allografting: A Preliminary Comparison of Arthroscopic and Open Anatomic Ligament Reconstruction. Orthop J Sports Med 2022; 10:23259671221126693. [PMID: 36250031 PMCID: PMC9561677 DOI: 10.1177/23259671221126693] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/26/2022] [Accepted: 07/12/2022] [Indexed: 11/07/2022] Open
Abstract
Background: Roughly 30% of patients with chronic lateral ankle instability (CLAI) have
long-lasting painful instability requiring surgical intervention. Ligament
reconstruction with the traditional open method and using tendon allografts
can provide sufficient mechanical stability for severe CLAI. Arthroscopic
ligament reconstruction with tendon allograft has recently been introduced
to treat CLAI. Purpose: In this study, we describe an arthroscopic ligament reconstruction procedure
involving the use of the tendon allograft for patients with CLAI, and we
compare the efficacy of this procedure with open ligament reconstruction
with tendon allograft. Study Design: Cohort study; Level of evidence, 3. Methods: We enrolled 10 patients (4 men and 6 women) with CLAI (mean age, 37.3 years;
range, 16-57 years) who underwent arthroscopic ligament reconstruction with
tendon allografting between November 2017 and June 2019. The control group
consisted of 10 patients who received open tendon allograft reconstruction.
Preoperative and 2-year postoperative functional outcomes were evaluated
using the American Orthopaedic Foot & Ankle Society ankle-hindfoot scale
(AOFAS), Karlsson Ankle Functional Score (KAFS), pain visual analog scale
(VAS), 12-Item Short Form Health Survey (SF-12), and Tegner activity score
(TAS). Results: The mean operative time was 118 and 110 minutes in the arthroscopic and open
groups, respectively. At 2-year follow-up, scores on the AOFAS improved
significantly compared with preoperatively, from 71.3 to 96.4
(P = .006) in the arthroscopic group, and from 68.6 to
96.7 (P = .005) in the open group. The postoperative AOFAS,
VAS, KAFS, and SF-12 scores did not differ significantly between the 2
groups; however, the TAS score was significantly higher in the arthroscopic
reconstruction group compared with in the open group (7 vs 6.1,
respectively; P = .01). Conclusion: Arthroscopic ligament reconstruction with tendon allografting resulted in
sufficient ankle stability and no donor-site morbidity. This procedure can
yield similar functional outcomes to open reconstruction technique and may
be an option for the management of CLAI.

The different subtalar ligaments show significant differences in their mechanical properties. Foot Ankle Surg 2022; 28:1014-1020. [PMID: 35190275 DOI: 10.1016/j.fas.2022.02.008] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/27/2021] [Revised: 02/01/2022] [Accepted: 02/14/2022] [Indexed: 02/04/2023]
Abstract
BACKGROUND Today, the relative contribution of each ligamentous structure in the stability of the subtalar joint is still unclear. The purpose of this study is to assess the material properties of the different ligamentous structures of the subtalar joint. METHODS Eighteen paired fresh-frozen cadaveric feet were used to obtain bone-ligament-bone complexes of the calcaneofibular ligament (CFL), the cervical ligament (CL) and the anterior capsular ligament-interosseous talocalcaneal ligament complex (ACaL-ITCL). The samples were subjected to uniaxial testing to calculate their respective stiffness and failure load. RESULTS The stiffness of ACaL-ITCL complex (mean: 150 ± 51 N/mm, 95% confidence interval (CI): 125.0-176.6 N/mm) was significantly higher than both CFL (mean: 55.8 ± 23.0 N/mm, CI: 43.8-67.7 N/mm) and CL (mean: 63.9 ± 38.0 N/mm, CI: 44.4-83.3 N/mm). The failure load of both the ACaL-ITCL complex (mean:382.5 ± 158 N, CI: 304.1-460.8 N) and the CFL (mean:320.4 ± 122.0 N, CI: 257.5-383.2 N) were significantly higher than that of the CL (mean:163.5 ± 58.0 N, CI: 131.3-195.7 N). The injury pattern demonstrated a partial rupture in all CFL and ACaL-ITCL specimens and in 60% of the CL specimens. CONCLUSION The CFL, CL and ACaL-ITCL show significant differences in their intrinsic mechanical properties. Both the CFL and CL are more compliant ligaments and seem to be involved in the development of subtalar instability. Based on the material properties, a gracilis tendon graft seems more appropriate than a synthetic ligament to reconstruct a CL or CFL. A partial rupture was the most commonly seen injury pattern in all ligaments. A fibular avulsion of the CFL was only rarely seen. The injury patterns need further investigation as they are important to optimize diagnosis and treatment.

Arthroscopic anatomical reconstruction of lateral collateral ligaments with ligament advanced reinforcement system artificial ligament for chronic ankle instability. World J Clin Cases 2022; 10:8893-8905. [PMID: 36157669 PMCID: PMC9477045 DOI: 10.12998/wjcc.v10.i25.8893] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/29/2021] [Revised: 12/04/2021] [Accepted: 07/31/2022] [Indexed: 02/05/2023] Open
Abstract
BACKGROUND Recently, the use of ligament advanced reinforcement system (LARS) artificial ligament, a new graft which has several unique advantages such as no donor-site morbidity, early recovery and no risk of disease transmission which has been a significant breakthrough for anatomical ligament reconstruction. Growing studies suggested that the special design of the LARS ligament with open fibers in its intra-articular part was believed to be more resistant to torsional fatigue and wearing. However, the safety and efficacy of LARS artificial ligament for ankle joint lateral collateral ankle ligament reconstruction has not been defined to date.
AIM To evaluate the clinical results of all-arthroscopic anatomical reconstruction of ankle joint lateral collateral ligaments with the LARS artificial ligament for chronic ankle instability.
METHODS Twenty-two patients with chronic lateral instability underwent anatomical reconstruction of the lateral collateral ligaments of ankle with LARS artificial ligament. The visual analogue score (VAS), American Orthopaedic Foot and Ankle Society score (AOFAS score) and Karlsson score were used to evaluate the clinical results before and after surgery.
RESULTS A total of 22 patients (22 ankles) were followed up for a mean of 12 mo. All patients reported significant improvement compared to their preoperative status. The mean AOFAS score improved from 42.3 ± 4.9 preoperatively to 90.4 ± 6.7 postoperatively. The mean Karlsson score improved from 38.5 ± 3.2 preoperatively to 90.1 ± 7.8 postoperatively. The mean VAS score improved from 1.9 ± 2.5 preoperatively to 0.8 ± 1.7 postoperatively.
CONCLUSION All-arthroscopic anatomical reconstruction of the lateral collateral ligaments with LARS artificial ligament achieved a satisfactory surgical outcome for chronic ankle instability.

Abstract
Background/aims Ankle sprains are common injuries which can lead to chronic lateral ankle ligament instability (CAI). Methods The aim of this review is to provide a comprehensive overview of the epidemiology, pathophysiology, investigation, surgical management and rehabilitation of CAI. Results Investigation of CAI is based on history, clinical examination, and imaging. Surgical management of CAI can be defined as anatomic reconstruction, anatomic and non anatomic repair of ATFL and/or CFL. Anatomic repair has been shown to have better functional outcomes and less secondary osteoarthritis when compared to non anatomic repair. Non-anatomic methods do not replicate the normal anatomical course of ATFL/CFL and may lead to stiffness. The most common surgical treatment for CAI is the open modified Broström repair augmented with the Gould modification. There are arthroscopic techniques being developed which have reported promising clinical results. However, there are considerable areas of further research which should be carried out to improve understanding and effectiveness of current treatment options. Standardised validated patient reported outcome measures and evidence-based protocols in the rehabilitation periods are crucial for positive and reproducible outcomes. Conclusion Surgical repair has proven to show excellent outcomes for patients suffering from CAI, however larger prospective studies should be carried out to evaluate the use of newer surgical techniques.

The clinical outcomes of surgical treatment for chronic ankle instability by anatomical reconstruction of the anterior talofibular ligament with autologous half-bundle peroneal longus tendon: A retrospective study. Front Surg 2022; 9:926825. [PMID: 35990101 PMCID: PMC9388904 DOI: 10.3389/fsurg.2022.926825] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/23/2022] [Accepted: 07/20/2022] [Indexed: 11/16/2022] Open
Abstract
The anterior talofibular ligament is the weakest and most vulnerable lateral ligament to be injured, and it can replace anatomical position through anatomical reconstruction. The purpose of this study is to evaluate clinical outcomes after an autologous half-bundle peroneus longus tendon anatomical reconstruction. We conducted a retrospective analysis by enrolling 34 patients [22 male and 12 female, median age 21 (range 19–26) years] with anterior talofibular ligament injury from January 2018 to March 2020. All patients underwent a ligament anatomical reconstruction operation with autologous half-bundle peroneus longus tendon and followed up with an average time of 16.21 ± 3.20 (range 12–24) months, with no loss of patients to follow-up during the study period. The American Orthopedic Foot, Ankle Society Score (AOFAS), Visual Analogue Score (VAS), and Anterior Tibiotalar Translation were used to assess the curative effect. All the indexes were compared between the preoperative and at the final follow-up to discover the related statistical differences. The AOFAS score improved significantly from an average preoperative score of 56.91 ± 3.79 to 94.12 ± 2.51 at the final followed-up (p < 0.001). Meanwhile, the pre-operation VAS pain score decreased from 5.94 ± 1.32 to 1.71 ± 0.87 (p < 0.001). Additionally, the Anterior tibiotalar translation decreased from 16.40 ± 1.85 to 5.20 ± 0.57 mm at the final followed-up (p < 0.001). The anterior drawer test was negative for all patients after the operation. Considering the outcomes, we concluded that anatomical reconstruction of the anterior talofibular ligament with autologous half-bundle peroneal longus tendon was a proper and safe procedure for chronic lateral ankle instability, and it had good clinical results and minimal complications.

Can Weightbearing Cone-beam CT Reliably Differentiate Between Stable and Unstable Syndesmotic Ankle Injuries? A Systematic Review and Meta-analysis. Clin Orthop Relat Res 2022; 480:1547-1562. [PMID: 35275097 PMCID: PMC9278899 DOI: 10.1097/corr.0000000000002171] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/21/2021] [Accepted: 02/18/2022] [Indexed: 02/06/2023]
Abstract
BACKGROUND Ankle injuries are common presentations to the emergency department and may lead to syndesmotic instability. These have a high socioeconomic burden due to prolonged rehabilitation, chronic pain, and posttraumatic arthritis. Early diagnosis is essential to minimize these complications, and the assessment of instability in the clinical setting is often limited by pain and clinician experience. Cross-sectional imaging of the distal syndesmosis accurately evaluates the syndesmosis through abnormal bony relationships, which in the presence of instability, worsens during physiological loading. Cone-beam CT (CBCT) has gained popularity in the diagnosis of these injuries because it enables syndesmotic assessment under weightbearing conditions, it mitigates the high radiation dose, and it is time-efficient. QUESTIONS/PURPOSES The purposes of this systematic review were: (1) to establish normal values for weightbearing CBCT of the syndesmosis in uninjured ankles and ascertain interobserver reliability and (2) to identify the impact of weightbearing on the syndesmosis in patients with occult ankle injuries and assess the effect of patient demographics on these metrics. METHODS This systematic review was reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and registered in PROSPERO (ID CRD42021248623). MEDLINE, PubMed, Embase, and Emcare databases were searched for studies assessing for syndesmotic instability, of which 307 studies were screened and 11 studies with 559 ankles in 408 uninjured patients and 151 patients with syndesmotic instability were included. All patients 18 years of age or older presenting with unilateral ankle injuries who underwent weightbearing CBCT for the diagnosis of an occult fracture or syndesmotic instability compared with the uninjured contralateral side were included. A control group of uninjured ankles was identified during weightbearing CBCT performed for other indications such as forefoot or midfoot injuries. Methodological assessment of the studies was performed using the Risk of Bias In Non-randomized Studies (ROBINS-1) tool and most included studies had a low risk of bias. Thus, a random-effects restricted maximum likelihood ratio model was used. RESULTS In the uninjured ankle, the mean area of the tibiofibular syndesmosis was 112.5 ± 7.1 mm 2 , which increased to 157.5 ± 9.6 mm 2 after injury when compared with uninjured ankles with a standardized mean difference of 29.5 (95% confidence interval 19.5 to 39.5; p < 0.01), and an excellent interobserver agreement (κ = 1.0 [95% CI 0.9 to 1.0]). However, syndesmosis volume decreased with age (β = -0.76; p = 0.04), and therefore, has a negative association with increasing age. CONCLUSION Our study has shown that the syndesmotic area is the most reliable parameter in the assessment of syndesmotic injuries because it increases in the presence of instability during weightbearing status. It is a composite measurement that could potentially allow clinicians to use weightbearing CBCT as an adjunct when there is a clinical suspicion of syndesmotic instability. Thus, weightbearing CBCT has the potential of being diagnostic of syndesmotic instability and should be evaluated against current radiological modalities to evaluate its accuracy.

Abstract
PURPOSE Psychological readiness scores have been developed to optimize the return to play in many sports-related injuries. The purpose of this study was to statistically validate the ankle ligament reconstruction-return to sport injury (ALR-RSI) scale after modified Broström-Gould (MBG) procedure. METHODS A similar version of the ACL-RSI scale with 12 items was adapted to quantify the psychological readiness to RTS after MBG and to describe construct validity, discriminant validity, feasibility, reliability and internal consistency of the scale, according to the COSMIN methodology. The term "knee" was replaced by "ankle". The AOFAS and Karlsson scores were used as references patient-related outcome measurements (PROMs). RESULTS A total of 71 patients were included. The ALR-RSI score after MBG procedure was highly (r > 0.5) correlated to the AOFAS and Karlsson scores, with a Pearson coefficient r = 0.69 [0.54-0.80] and 0.72 [0.53-0.82], respectively. The mean ALR-RSI score was significantly greater in the subgroup of 55 patients who resumed sports activity compared to those that no longer practiced sport: 61.9 (43.8-79.6) vs 43.4 (25.0-55.6), (p = 0.01). The test-retest showed an "excellent" reproducibility with a ρ intraclass correlation coefficient of 0.93 [0.86-0.96]. The Cronbach's alpha statistic was 0.95, attesting an "excellent" internal consistency between the 12 ALR-RSI items. CONCLUSION The ALR-RSI score is a valid and reproducible tool for the assessment of psychological readiness to RTS after an MBG procedure for the management of CLAI, in a young and active population. The ALR-RSI score may help to identify and counsel athletes on their ability to return to sport. LEVEL OF EVIDENCE III.

Which Functional Tests and Self-Reported Questionnaires Can Help Clinicians Make Valid Return to Sport Decisions in Patients With Chronic Ankle Instability? A Narrative Review and Expert Opinion. Front Sports Act Living 2022; 4:902886. [PMID: 35721875 PMCID: PMC9204606 DOI: 10.3389/fspor.2022.902886] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2022] [Accepted: 05/04/2022] [Indexed: 12/26/2022] Open
Abstract
Lateral ankle sprain is the most common injury in sports, with up to 40% of patients developing chronic ankle instability (CAI). One possible cause underlying this high rate of recurrence or feeling of giving way may be a premature return to sport (RTS). Indeed, except for time-based parameters, there are no specific criteria to guide clinicians in their RTS decisions in patients with CAI. A recent international consensus highlighted the relevance and importance of including patient-reported ankle function questionnaires combined with functional tests targeting ankle impairments in this population. Thus, the aim of this narrative review and expert opinion was to identify the most relevant functional performance tests and self-reported questionnaires to help clinicians in their RTS decision-making process following recurrent ankle sprains or surgical ankle stabilization. The PubMed (MEDLINE), PEDro, Cochrane Library and ScienceDirect databases were searched to identify published articles. Results showed that the single leg stance test on firm surfaces, the modified version of the star excursion balance test, the side hop test and the figure-of-8 test appeared to be the most relevant functional performance tests to target ankle impairments in patients with CAI. A combination of the Foot and Ankle Ability Measure (FAAM) and the Ankle Ligament Reconstruction-Return to Sport after Injury (ALR-RSI) questionnaires were the most relevant self-reported questionnaires to assess patient function in the context of CAI. Although these functional tests and questionnaires provide a solid foundation for clinicians to validate their RTS decisions in patient with CAI, objective scientific criteria with cut-off scores are still lacking. In addition to the proposed test cluster, an analysis of the context, in particular characteristics related to sports (e.g., fatigue, cognitive constraints), to obtain more information about the patient's risk of recurrent injury could be of added value when making a RTS decision in patients with CAI. In order to evaluate the strength of evertors under ecological conditions, it would also be interesting to assess the ability to control weight-bearing ankle inversion in a unipodal stance. Further studies are needed to assess the relevance of this proposed test cluster in RTS decision-making following lateral ankle sprain injury and CAI.

Effect of Ligament Mapping from Different Magnetic Resonance Image Quality on Joint Stability in a Personalized Dynamic Model of the Human Ankle Complex. APPLIED SCIENCES-BASEL 2022.

Abstract
Background. Mechanical models of the human ankle complex are used to study the stabilizing role of ligaments. Identification of ligament function may be improved via image-based personalized approach. The aim of this study is to compare the effect of the ligament origin and insertion site definitions obtained with different magnetic resonance imaging (MRI) modalities on the mechanical behaviour of a dynamic model of the ankle complex. Methods. MRI scans, both via 1.5 T and 3.0 T, were performed on a lower-limb specimen, free from anatomical defects, to obtain morphological information on ligament-to-bone attachment sites. This specimen was used previously to develop the dynamic model. A third ligament attachment site mapping scheme was based on anatomical dissection of the scanned specimen. Following morphological comparison of the ligament attachment sites, their effect on the mechanical behaviour of the ankle complex, expressed by three-dimensional load–displacement properties, was assessed through the model. Results. Large differences were observed in the subtalar ligament attachment sites between those obtained through the two MRI scanning modalities. The 3.0 T MRI mapping was more consistent with dissection than the 1.5 T MRI. Load–displacement curves showed similar mechanical behaviours between the three mappings in the frontal plane, but those obtained from the 3.0 T MRI mapping were closer to those obtained from dissection. Conclusions. The state-of-the-art 3.0 T MRI image analysis resulted in more realistic mapping of ligament fibre origin and insertion site definitions; corresponding load–displacement predictions from a subject-specific model of the ankle complex showed a mechanical behaviour more similar to that using direct ligament attachment observations.
