Fantasy football points capture performance declines in National Football League offensive skill players following an ankle injury. J Orthop 2024; 52:124-128. [PMID: 38596620 PMCID: PMC10999692 DOI: 10.1016/j.jor.2024.03.030] [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: 02/24/2024] [Revised: 03/24/2024] [Accepted: 03/26/2024] [Indexed: 04/11/2024] Open
Abstract
Background The ankle is one of the anatomic sites most frequently injured in National Football League (NFL) players. Ankle injuries have previously been shown to have long-lasting negative impacts, and have been associated with impaired athletic performance. The aim of this study was to use fantasy football points as a metric to evaluate the impact of ankle injuries on NFL offensive skill player performance. Methods An open-access online database was used to identify NFL players who sustained ankle injuries from 2009 to 2020. Another public online database was used to determine fantasy points and other performance metrics for injured offensive skill players in the seasons before and after their ankle injury. Injured players were matched to a healthy control by position, age, and BMI. Paired T-tests were performed to evaluate performance metrics before and after the ankle injury. An ANCOVA was performed to assess the effect of return to play (RTP) time and injury type on fantasy performance. Results 303 players with ankle injuries were included. Fantasy output, including average points per game (PPG) and total fantasy points accrued in one season, significantly decreased in the season following a player's ankle injury (p < 0.0001). In running backs, tight ends, and wide receivers, performance significantly decreased in every metric evaluated (p < 0.0001). In quarterbacks, there was no significant change in performance, except for a decrease in the number of games played (p = 0.0033) and in the number of interceptions thrown (p = 0.029). Conclusion Assessing fantasy football output revealed a decrease in player performance in the season following an ankle injury, especially in route-running players. These results can be used to inform injury prevention and rehabilitation practices in the NFL.

Venous thromboembolism (VTE) developing after ankle sprain. Comparison with VTE after knee arthroplasty. Thromb Res 2024; 237:94-99. [PMID: 38574519 DOI: 10.1016/j.thromres.2024.03.018] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2024] [Revised: 03/09/2024] [Accepted: 03/17/2024] [Indexed: 04/06/2024]
Abstract
BACKGROUND Venous thromboembolism (VTE) is a critical complication after non-major trauma or surgery. While the risk and severity of VTE following major orthopedic surgery is well-documented, there is significant knowledge gap regarding, non-major trauma such as ankle sprains. METHODS We analyzed data from the RIETE registry to assess the clinical characteristics, VTE prophylaxis usage, and outcomes in patients with VTE following ankle sprain versus those post elective knee arthroplasty. We aimed to assess the risk and severity of VTE in a population traditionally considered at lower risk. Risk stratification was performed using the TRiP(cast) score. RESULTS Among 1,250 patients with VTE, those with ankle sprain (n = 459) were much younger than those post knee arthroplasty (n = 791), less often female, had fewer comorbidities, and received VTE prophylaxis less often (27% vs. 93 %). During anticoagulation, 26 patients developed recurrent VTE, 31 had major bleeding, and 12 died (fatal PE 3, fatal bleeding 2). There were no differences between the two groups in the rates of VTE recurrences (rate ratio (RR): 1.65; 95%CI: 0.69-3.88) or death (RR: 1.12; 95%CI: 0.33-3.46), but patients with VTE after ankle sprain had a lower rate of major bleeding (RR: 0.39; 95%CI: 0.13-0.99). CONCLUSIONS Ankle sprain patients are often undertreated for VTE prophylaxis and have similar severity of VTE than those undergoing elective knee surgery, indicating the need for a more customized approach to VTE management.

Effectiveness of photobiomodulation therapy in the treatment of patients with an ankle sprain: a systematic review and meta-analysis. Lasers Med Sci 2024; 39:116. [PMID: 38668764 DOI: 10.1007/s10103-024-04063-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2023] [Accepted: 04/19/2024] [Indexed: 05/02/2024]
Abstract
BACKGROUND Photobiomodulation therapy (PBMT) is widely used in the treatment of patients with musculoskeletal and sports disorders with a lack of significance in patients with sprain ankle. PURPOSE This review investigated the effect of PBMT on pain, oedema, and function in patients with an ankle sprain. METHODS A systematic search of the databases (MEDLINE, PubMed, EBSCO, Web of Science, Wiley Online Library, Science Direct, Physiotherapy Evidence (PEDro), and the Cochrane Databases) was performed from inception to the end of 2023 to identify any clinical study investigating the effect of PBMT on ankle sprain. PBMT parameters and measured outcomes were extracted. The primary measured outcome was pain and function, and oedema were secondary measured outcomes. Methodological quality was assessed using the PEDro scale. The level of evidence was determined by the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system. A random effect meta-analysis with forest plot was used to calculate standardized mean difference (SMD) at a 95% confidence interval and the overall effect size (ES). RESULTS Six studies (598 patients) were included in the review and five studies in the meta-analysis. There were two fair-quality and four good-quality studies, with a moderate level of evidence on pain, and a low level of evidence on oedema and function. The meta-analysis revealed a significant overall effect of PBMT on pain with high ES [SMD - 0.88 (-1.76, -0.00), p = 0.05], with a non-significant effect on oedema and function with a medium ES [SMD - 0.70 (-1.64, 0.24), p = 0.14] on oedema and low ES on function [SMD - 0.22 (-0.69, 0.24), p = 0.35]. Significant heterogeneity was observed in all measured outcomes with high heterogeneity (I2 > 75%) in pain and oedema and moderate heterogeneity in function. CONCLUSION PBMT is quite effective for patients with an ankle sprain. PBMT showed high effect size with a moderate level of evidence on pain intensity. The lack of significant effects of PBMT on function and edema with low level of evidence limit the confidence to the current results and recommend further large high-quality studies with higher PBMT intensity and fluency for standardisation of the irradiation parameters and treatment protocol.

Study on the effect of blood flow restriction training combined with IASTAM on ankle strength and function intervention in athletes with chronic ankle instability in sport dance events. BMC Sports Sci Med Rehabil 2024; 16:81. [PMID: 38605396 PMCID: PMC11007892 DOI: 10.1186/s13102-024-00873-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/19/2024] [Accepted: 04/01/2024] [Indexed: 04/13/2024]
Abstract
BACKGROUND Athletes engaged in sports dance frequently encounter the potential for ankle injuries and instability, factors that may contribute to diminished training efficacy, compromised athletic performance, prolonged recuperation, and heightened susceptibility to recurring injuries. OBJECTIVE The objective of this study was to investigate the impact of an exercise intervention (comprising blood flow restriction training combined with low-load ankle muscle strength training and balance training) as well as instrument-assisted soft tissue mobilization (IASTM) on the foot and ankle function, strength, and range of motion in sports dance athletes exhibiting ankle instability (CAI). METHODS Thirty participants exhibiting ankle instability, restriction, or discomfort were recruited and randomly assigned to two groups: the Test group (comprising blood flow restriction training combined with IASTM, n = 15) and the traditional ankle strength training group (n = 15). The intervention spanned 4 weeks, with one session per week. Assessment of the Cumberland Ankle Instability Tool (CAIT), Foot and Ankle Ability Measure (FAAM), and ankle range of motion occurred at three time points: pre-intervention, immediately following the initial intervention, and after 4 weeks of intervention. Ankle strength testing was conducted solely before and after the intervention for comparative analysis. RESULTS There were no significant variances in baseline characteristics between the two intervention groups. In terms of CAIT scores, both groups exhibited notably higher scores following the initial intervention and after 4 weeks of intervention compared to pre-intervention (P < 0.05). The Test group displayed higher CAIT scores than the control group, signifying a more pronounced enhancement in ankle stability among patients in the Test group. Concerning FAAM scores, both groups significantly enhanced ankle function in CAI patients (P < 0.05), with the Test group demonstrating notably higher FAAM-SPORT scores than the control group (P < 0.05), indicating superior restoration of athletic capability in the Test group. As for improvements in ankle range of motion, both groups demonstrated significant enhancements compared to pre-intervention (P < 0.05). The Test group exhibited significantly superior improvements in dorsiflexion, eversion, and inversion range of motion compared to the control group (P < 0.05), while the control group did not exhibit significant enhancements in plantarflexion and eversion range of motion (P > 0.05). Both groups displayed enhanced ankle strength in CAI patients following the intervention (P < 0.05), with the Test group manifesting notably higher dorsiflexion and inversion strength than the control group (P < 0.05). CONCLUSION Both blood flow restriction training combined with IASTM and traditional ankle strength and stability training have shown significant improvements in stability, function, strength, and range of motion in CAI patients. Furthermore, the Test group exhibits superior efficacy in ankle stability, daily functional movement, dorsiflexion, and eversion range of motion compared to the control group.

Pediatric osteochondral fractures: clinical insights associate early diagnosis to early rehabilitation via arthroscopy. EUROPEAN JOURNAL OF ORTHOPAEDIC SURGERY & TRAUMATOLOGY : ORTHOPEDIE TRAUMATOLOGIE 2024; 34:1657-1665. [PMID: 38376585 PMCID: PMC10980612 DOI: 10.1007/s00590-024-03852-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/10/2023] [Accepted: 02/01/2024] [Indexed: 02/21/2024]
Abstract
PURPOSE This retrospective observational cohort analysis aims to address diagnostic and therapeutic challenges in managing osteochondral fractures (OCFs) resulting from acute patella dislocation and ankle sprains in children. METHODS The study includes 15 children treated for OCFs between January 2020 and July 2022. Data were obtained from medical records and analyzed using logistic regression. RESULTS The diagnostic and treatment algorithm involves detailed history, clinical examination, and imaging, with MRI guiding therapeutic decisions. Arthroscopic or mini open fixation led to successful rehabilitation, with 93% achieving full mobility at 9 months. Age was identified as a slight risk factor for free fragments in MRI, and arthroscopic management correlated with faster recovery at 3 months. CONCLUSION This study underscores the importance of immediate diagnosis and minimally invasive intervention for OCFs in children. Timely treatment, guided by a diagnostic algorithm, facilitates joint restoration and prevents degenerative consequences, ensuring a return to regular activities within a year postoperatively.

Exploring influences and risk of bias of studies on return to sport and work after lateral ankle sprain: A systematic review and meta-analysis. World J Meta-Anal 2024; 12:87026. [DOI: 10.13105/wjma.v12.i1.87026] [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: 07/19/2023] [Revised: 09/26/2023] [Accepted: 01/02/2024] [Indexed: 03/08/2024] Open
Abstract
BACKGROUND Lateral ankle sprains are the most common traumatic musculoskeletal injuries of the lower extremity, with an incidence rate of 15%-20%. The high incidence and prevalence highlights the economic impact of this injury. Ankle sprains lead to a high socioeconomic burden due to the combination of the high injury incidence and high medical expenses. Up to 40% of patients who suffer from an ankle sprain develop chronic ankle instability. Chronic instability can lead to prolonged periods of pain, immobility and injury recurrence. Identification of factors that influence return to work (RTW) and return to sports (RTS) after a lateral ankle sprain (LAS) may help seriously reduce healthcare costs.
AIM To explore which factors may potentially affect RTW and RTS after sustaining an LAS.
METHODS EMBASE and PubMed were systematically searched for relevant studies published until June 2023. Inclusion criteria were as follows: (1) Injury including LAS or chronic ankle instability; (2) Described any form of treatment; (3) Assessment of RTW or RTS; (4) Studies published in English; and (5) Study designs including randomized controlled clinical trials, clinical trials or cohort studies. Exclusion criteria were: (1) Studies involving children (age < 16 year); or (2) Patients with concomitant ankle injury besides lateral ankle ligament damage. A quality assessment was performed for each of the included studies using established risk of bias tools. Additionally quality of evidence was assessed using the GRADEpro tool in cases where outcomes were included in the quantitative analysis. A best evidence synthesis was performed in cases of qualitative outcome analysis. For all studied outcomes suitable for quantitative analysis a forest plot was created to calculate the effect on RTW and RTS.
RESULTS A total of 8904 patients were included in 21 studies, 10 randomized controlled trials, 7 retrospective cohort studies and 4 prospective cohort studies. Fifteen studies were eligible for meta-analysis. The overall RTS rate ranged were 80% and 83% in the all treatments pool and surgical treatments pool, respectively. The pooled mean days to RTS ranged from 23-93 d. The overall RTW rate was 89%. The pooled mean time to RTW ranged from 5.8-8.1 d. For patients with chronic ankle instability, higher preoperative motivation was the sole factor significantly and independently (P = 0.001) associated with the rate of and time to RTS following ligament repair or reconstruction. Higher body mass index was identified as a significant factor (P = 0.04) linked to not resuming sports or returning at a lower level (median 24, range 20-37), compared to those who resumed at the same or higher level (median 23, range 17-38). Patients with a history of psychological illness or brain injury, experienced a delay in their rehabilitation process for sprains with fractures and unspecified sprains. The extent of the delayed rehabilitation was directly proportional to the increased likelihood of experiencing a recurrence of the ankle sprain and the number of ankle-related medical visits. We also observed that 10% of athletes who did return to sport after lateral ankle sprain without fractures described non-ankle-related reasons for not returning.
CONCLUSION All treatments yielded comparable results, with each treatment potentially offering unique advantages or benefits. Preoperative motivation may influence rehabilitation after LAS. Grading which factor had a greater impact was not possible due to the lack of comparability among the included patients.

Validity and reliability of the Modified Four Square Step Test in individuals with ankle sprain. J Orthop Surg Res 2024; 19:182. [PMID: 38491530 PMCID: PMC10941393 DOI: 10.1186/s13018-024-04664-5] [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: 12/21/2023] [Accepted: 03/04/2024] [Indexed: 03/18/2024] Open
Abstract
BACKGROUND Postural instability and gait abnormalities are frequently observed after an ankle sprain. A modified Four Square Step Test (mFSST) was developed to assess dynamic balance during gait. The aim of this study was to evaluate the reliability and validity of the mFSST in individuals with ankle sprains. METHODS The study included 39 individuals with grade 1 and 2 ankle sprains with a mean age of 30.36 ± 6.21 years. The dynamic balance of the participants was assessed with the mFSST and Timed Up & Go test (TUG). To determine the test-retest reliability of the mFSST, the test was repeated approximately 1 h apart. RESULTS The test-retest reliability of the mFSST was excellent (ICC = 0.85). Furthermore, when the concurrent validity of the mFSST was examined, a high correlation was found between with the TUG (r = 0.78, p < 0.001). CONCLUSION The mFSST is a valid and reliable clinical assessment method for evaluating dynamic balance during walking in individuals with ankle sprains. We think that the mFSST is preferable in clinical evaluations because its platform is easy to prepare and requires very little equipment.

Gait and muscle activity measures after biomechanical device therapy in subjects with ankle instability: A systematic review. Foot (Edinb) 2024; 59:102083. [PMID: 38513375 DOI: 10.1016/j.foot.2024.102083] [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: 10/15/2023] [Revised: 02/18/2024] [Accepted: 03/08/2024] [Indexed: 03/23/2024]
Abstract
INTRODUCTION Health specialists suggest a conservative approach comprising non-pharmacological interventions as the initial course of action for individuals with repetitive ankle sprain due to ankle instability. This systematic review aimed to assess the effectiveness of biomechanical devices (Foot Orthoses, Ankle Orthoses, and Taping) on gait and muscle activity in individuals with ankle instability. METHODS A systematic search was performed on electronic databases, including PubMed, EMBASE, Clinical Trials.gov, Web of Science, and Scopus. The PEDro scoring system was used to evaluate the quality of the included studies. We extracted data from population, intervention, and outcome measures. RESULTS In the initial search, we found 247 articles. After following the steps of the PRISMA flowchart, only 22 reports met the inclusion criteria of this study. The results show that biomechanical device therapy may increase swing time, stance time, and step. Additionally, studies suggest that these devices can reduce plantar flexion, inversion, and motion variability during gait. Biomechanical devices have the potential to optimize the subtalar valgus moment, push-off, and braking forces exerted during walking, as well as enhance the activity of specific muscles including the peroneus longus, peroneus brevis, tibialis anterior, gluteus medius, lateral gastrocnemius, rectus femoris, and soleus. CONCLUSION Biomechanical devices affect gait (spatiotemporal, kinetic, and kinematic variables) and lower limb muscle activity (root mean square, reaction time, amplitude, reflex, and wave) in subjects with ankle instability.

Muscle contributions to reduced ankle joint contact force during drop vertical jumps in patients with chronic ankle instability. J Biomech 2024; 163:111926. [PMID: 38183761 DOI: 10.1016/j.jbiomech.2024.111926] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2023] [Revised: 12/05/2023] [Accepted: 01/02/2024] [Indexed: 01/08/2024]
Abstract
Chronic ankle instability is a condition linked to progressive early ankle joint degeneration. Patients with chronic ankle instability exhibit altered biomechanics during gait and jump landings and these alterations are believed to contribute to aberrant joint loading and subsequent joint degeneration. Musculoskeletal modeling has the capacity to estimate joint loads from individual muscle forces. However, the influence of chronic ankle instability on joint contact forces remains largely unknown. The objective of this study was to compare tri-axial (i.e., compressive, anterior-posterior, and medial-lateral) ankle joint contact forces between those with and without chronic ankle instability during the ground contact phase of a drop vertical jump. Fifteen individuals with and 15 individuals without chronic ankle instability completed drop vertical jump maneuvers in a research laboratory. We used those data to drive three-dimensional musculoskeletal simulations and estimate muscle forces and tri-axial joint contact force variables (i.e., peak and impulse). Compared to those without chronic ankle instability, the ankles of patients with chronic ankle instability underwent lower compressive ankle joint contact forces as well as lower anterior-posterior and medial-lateral shearing forces during the weight acceptance phase of landing (p <.05). These findings suggest that patients with chronic ankle instability exhibit lower ankle joint loading patterns than uninjured individuals during a drop vertical jump, which may be considered in rehabilitation to potentially reduce the risk of early onset of ankle joint degeneration.

Abstract
OBJECTIVE The aim of this study was to compare muscle strength, balance, and physical activity between children with chronic ankle instability and copers. DESIGN Cross-sectional study. SETTING Pediatric Physical Therapy laboratory. PARTICIPANTS Children aged between 7 and 12 years old from regular schools who had a history of unilateral ankle sprain. MAIN OUTCOME MEASURES Lower extremity strength, Static and dynamic standing balance, and Level of physical activity. RESULTS Fifteen children with chronic ankle instability and 15 copers were recruited. Demographic data showed no differences between group except for sex and the Cumberland Ankle Instability Tool-Youth (CAITY) score. Children with CAI had a significantly lower score during the standing long jump test (p < 0.05), poorer performance of single leg stance test (p < 0.001) and Y-Balance test in the anterior, posteromedial, and posterolateral directions (p < 0.05) when compared to copers. Total METs per week was significantly higher in the copers (p < 0.05). CONCLUSION Children with chronic ankle instability exhibited weaker lower limb strength, poorer static and dynamic standing balance, and participate in less physical activity compared to those in a coper group which may have future negative health consequences. Knowledge about the differences between the two groups may provide guidance for physical educators and physical therapists. (200 words).

Abstract
PURPOSE The functional role of the calcaneofibular ligament (CFL) is still controversial. We aimed to investigate the anatomical features of the CFL on sonography and the elastic modulus of the CFL in different ankle positions using ultrasound shear-wave elastography (SWE). METHODS In 14 cadaveric ankles, the angle of the CFL with respect to the long axis of the fibula was measured in the following ankle positions: neutral (N), 30° plantar flexion (PF), and 20° dorsiflexion (DF). In addition, in 24 ankles of healthy adult volunteers, the elastic modulus of the CFL was evaluated with ultrasound SWE in the following ankle positions: neutral (N), 30° plantar flexion with inversion (PI), 30° plantar flexion with eversion (PE), 20° dorsiflexion with inversion (DI), and 20° dorsiflexion with eversion (DE). RESULTS The mean angle of the CFL in N, PF, and DF positions was 139.9° ± 12.7°, 121.3° ± 14.1°, and 158.6° ± 13.1°, respectively. The angle of the CFL in N was significantly greater than that in PF and smaller than that in DF (P < 0.0001, both). The mean elastic modulus of the CFL in the N, PI, PE, DI, and DE positions was: 63.6 ± 50.8, 148.0 ± 39.4, 75.8 ± 40.6, 88.1 ± 31.6, and 61.7 ± 29.4 kPa, respectively. The elastic modulus in PI was significantly higher than in other positions, while the values obtained in DI and DE were also significantly different (P < 0.001, both). CONCLUSIONS The angle of the CFL increased with DF. Moreover, ultrasound SWE showed that the CFL was tensed and likely to be injured in the PI position.

Abstract
BACKGROUND Chronic ankle instability (CAI) is the most common injury in youth sports, which leads to psychological stress from doubting their performance. Cost effective and easy to access tool to reduce the stress among this target group are desired. Therefore, the purpose of this study was to investigate the effect of adding on intervention with short-duration deep breathing (SDDB) alongside with conventional physiotherapy (CP) among young adults with chronic ankle instability (CAI). METHODS Total of 30 CAI participants attended physiotherapy, who were randomly assigned into control and experimental groups. The participants in the experimental group received combined intervention (SDDB + CP), and the control group received CP for 6 weeks. The effectiveness of interventions was assessed at 3 intervals with a battery of questionnaires (Visual Analog Score, Cumberland Ankle Instability Tool, Mindful Attention Awareness Scale, and Oxford Happiness Questionnaire) at the end of week 3, week 6, and week 12 as follow-up. A two-way repeated measures of ANOVA was applied to report the statistical significance at p < 0.05. RESULTS The results showed a better improvement in pain, balance, happiness, and mindfulness attention among participants in the experimental group, with a significant improvement in mindful attention over the time point as compared to the control group. CONCLUSION The findings provide insight into incorporating SDDB additions to the existing CP for better CAI management. Breathing techniques that improve attention and happiness play a vital role in CAI, which recommends the biopsychosocial approach in chronic injury rehabilitation.

Abstract
OBJECTIVES To establish preliminary gait training dosage parameters for patients with chronic ankle instability (CAI) by determining the within-session and between-session effects of auditory biofeedback training on center of pressure (COP) location during gait. DESIGN Observational Longitudinal. SETTING Laboratory. PARTICIPANTS 19 participants with CAI, 8 participants who did not receive auditory biofeedback (NoFeedback group) and 11 participants who did receive auditory biofeedback (AuditoryFeedback group) over an 8-session 2-week intervention. MAIN OUTCOME MEASURES COP location was measured at the start and at each 5-min interval during treadmill walking across all eight 30-min training sessions. RESULTS The AuditoryFeedback group had significant within-session lateral-to-medial shifts in COP location during only session-1 at the 15-min (45% of stance; peak mean difference = 4.6 mm), 20-min (35% and 45%; 4.2 mm), and 30-min time intervals (35% and 45%; 4.1 mm). Furthermore, the AuditoryFeedback group had significant between-session lateral-to-medial shifts in COP location at session-5 (35-55% of stance; 4.2 mm), session-7 (35%-95%; 6.7 mm), and session-8 (35%-95%; 7.7 mm). The NoFeedback group had no significant changes in COP location within-sessions or between-sessions. CONCLUSIONS Participants with CAI who received auditory biofeedback during gait needed an average of 15-min during session-1 to meaningfully shift their COP location medially and 4-sessions before retaining the adapted gait pattern.

How robust are clinical trials in primary and secondary ankle sprain prevention? Phys Ther Sport 2023; 64:85-90. [PMID: 37801794 DOI: 10.1016/j.ptsp.2023.08.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/14/2023] [Revised: 08/24/2023] [Accepted: 08/25/2023] [Indexed: 10/08/2023]
Abstract
OBJECTIVES Determine the statistical stability of RCTs examining primary and secondary prevention of ankle sprains. METHODS Databases were searched to August 2023. We included parallel design RCTs, using conservative interventions for preventing ankle sprain, reporting dichotomous injury event outcomes. Statistical stability was quantified using Fragility Index (FI) and Fragility Quotient (FQ). Subgroup analyses were undertaken to test if FI varied based on by study objective, original approach to analysis (frequency vs time to event), follow-up duration, and pre-registration. RESULTS 3559 studies were screened with 45 RCTs included. The median number of events required to change the statistical significance (FI) was 4 (IQR 1-6). FI was similar regardless of study objective, original analysis, follow-up duration, and pre-registration status. Median (IQR) FQ was 0.015 (0.005-0.046), therefore reversing events <2 patients/100 would alter significance. In 80% of studies the number of patients lost to follow-up was greater than the FI. CONCLUSION RCTs informing primary and secondary prevention of ankle sprain are fragile. Only a small percentage of outcome event reversals would reverse study significance, and this is often exceeded by the number of drop outs. Robust reporting of dichotomous outcomes requires the use P values and key metrics such as FI or FQ.

Decreased rate of torque development in ankle evertors for individuals with chronic ankle instability. Clin Biomech (Bristol, Avon) 2023; 109:106096. [PMID: 37725866 DOI: 10.1016/j.clinbiomech.2023.106096] [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: 06/12/2023] [Revised: 08/30/2023] [Accepted: 09/12/2023] [Indexed: 09/21/2023]
Abstract
BACKGROUND Individuals with chronic ankle instability have decreased peak torque during maximum voluntary contraction in ankle evertors/invertors, and hip abductors. However, it is unclear whether individuals with chronic ankle instability and/or copers demonstrate decreased rate of torque development in ankle evertors/invertors, and hip abductors. METHODS 54 university-aged participants (18 chronic ankle instability, 18 copers, and 18 controls) performed three maximal isometric contractions for ankle evertors and invertors, and hip abductors. Rate of torque development was defined as the linear slope of the torque-time curve during the first 200 ms of each contraction and compared between the three groups using a one-way analysis of variance (α = 0.05). FINDINGS The chronic ankle instability group showed 38.1% less rate of torque development than the coper (P = 0.03 and d = 0.84) and 37.1% than the control groups (P = 0.03 and d = 1.03) in the ankle evertors. For the hip abductors, there were moderate effects between the chronic ankle instability group and the copers (P = 0.06 and d = 0.70), and control groups (P = 0.06 and d = 0.75). INTERPRETATIONS The observed between-groups differences in rate of torque development indicate that restoring rate of torque development after lateral ankle sprain may be important to reduce risk of reinjury and development of chronic ankle instability. Clinicians should consider the rate of torque development in the ankle evertors and hip abductors during rehabilitation chronic ankle instability patients.

Abstract
STUDY DESIGN Evaluation of the psychometric properties of a translated, culturally adapted questionnaire. OBJECTIVE Translating, culturally adapting, and validating the Italian version of the Cumberland Ankle Instability Tool (CAIT-I). SUMMARY OF BACKGROUND DATA Ankle sprains are one of the most common musculoskeletal injuries and can lead to chronic ankle instability (CAI). The International Ankle Consortium recommends the Cumberland Ankle Instability Tool (CAIT) as a valid and reliable self-report questionnaire assessing the presence and severity of CAI. At this moment, there is no validated Italian version of CAIT. METHODS The Italian version of the CAIT (CAIT-I) was developed by an expert committee. Test-retest reliability of the CAIT-I was measured in 286 healthy and injured participants within a 4-9-day period, by using Intraclass Correlation Coefficients (ICC2,1). Construct validity, exploratory factor analysis, internal consistency and sensitivity were examined in a sample of 548 adults. Instrument responsiveness over 4 time points was determined in a subgroup of 37 participants. RESULTS The CAIT-I demonstrated excellent test-retest reliability (ICC≥0.92) and good internal consistency (α = .84). Construct validity was confirmed. Identified cut-off for the presence of CAI was 24.75, with sensitivity= 0.77 and specificity= 0.65. There were significant differences across time for CAIT-I scores (P < .001), demonstrating responsiveness to change, but no floor or ceiling effects. CONCLUSION The CAIT-I demonstrates acceptable psychometric performance as a screening and outcome measure. The CAIT-I is a useful tool to assess the presence and severity of CAI.

Abstract
OBJECTIVES Evaluate if non-elite netballers sought health care, treatments received, and return-to-play decisions after an ankle sprain, including intercountry differences. DESIGN Cross-sectional survey. METHODS Non-elite netballers aged >14 years were recruited from Australia, United Kingdom, and New Zealand. Participants completed an online survey regarding their last ankle sprain and were queried regarding health care sought, health professionals consulted, treatments received, time missed, and return-to-play clearance. Data were described using number (proportion) for the overall cohort and countries. Between-country differences in health care use were compared using chi-square tests. Descriptive statistics were presented for management practices. RESULTS We received 1592 responses from Australian (n = 846), United Kingdom (n = 454), and New Zealand (n = 292) netballers. Three in five (n = 951, 60 %) sought health care. Of those, most consulted a physiotherapist (n = 728, 76 %), received strengthening exercises (n = 771, 81 %), balance exercises (N = 665, 70 %) and taping (n = 636, 67 %). Few received return-to-play clearance (n = 362, 23 %). Comparing countries, fewer United Kingdom netballers sought health care than Australian and New Zealand netballers (Australia: 60 % vs United Kingdom: 53 % vs New Zealand: 68 %, p < 0.001), consulted a physiotherapist (Australia: 79 %, United Kingdom: 63 %, New Zealand: 87 %), received strengthening (Australia: 84 %, United Kingdom: 73 %, New Zealand: 84 %) or balance exercises (Australia: 71 %, United Kingdom: 60 %, New Zealand: 80 %) or taping (Australia: 74 %, United Kingdom: 39 %, New Zealand: 82 %). More Australian netballers returned to play within 1-7 days (Australia: 25 %, United Kingdom: 15 %, New Zealand: 21 %) and fewer United Kingdom netballers received return-to-play clearance (Australia: 28 %, United Kingdom: 10 %, New Zealand: 28 %). CONCLUSIONS Health-seeking behaviours are adopted by some, but not all netballers after an ankle sprain. For those who sought care, most consulted a physiotherapist and were prescribed exercise-based interventions and external ankle support, but few received return-to-play clearance. Comparing countries, United Kingdom netballers had lower health-seeking behaviours and received less best-practice management than Australian and New Zealand netballers.

Abstract
Introduction One of the most common orthopedic injury injuries seen in patients at the emergency department is that of the ankle. There are some efficient protocols for their treatment, but more often the clinician is fo-cused in finding and treating possible fractures and disregards ligamentous lesions that lead to instabil-ity, if they become chronic. Case Report A patient that suffered an ankle sprain was improperly handled, developed lateral instability of the ankle, and was treated surgically using an autologous semitendinosus graft. A 42-year year-old Caucasian male that after an ankle sprain was examined in various primary health -care centers, four times within six 6 months, with persistent symptoms of his left ankle. After all these months, he was eventually diagnosed with post-traumatic lateral instability of the ankle that was resistant to con-servative treatment. In stress view X-rays, the talar tilt angle was 21°ο and the anterior drawer was measured at 13 mm. The patient was treated surgically with reconstruction of the anterior talofibular and the calcaneofibular ligament using an autologous semitendinosus graft from the left knee. The graft was pinned in the anatomical insertion sites of the ligaments with absorbable screws. A post-surgical physiotherapy regimen was applied for two 2 months. In the post-surgical dynamic stress view X-rays, the talar tilt angle and the anterior drawer were markedly improved, measured at 3°ο and 4 mm, respec-tively. In 11 months post-surgical follow-up, the patient's American Foot and Ankle Score was 85, from the 60 evaluated before treatment. Conclusion The use of guidelines, regular follow-ups, and functional rehabilitation are key factors to treating ankle injuries. The reconstruction of lateral collateral ligament complex with a semitendinosus graft is one of the surgical options for restoring lateral ankle instability.

Abstract
INTRODUCTION Ankle sprain is a common musculoskeletal injury that leads to recurrent instability. Repeated ankle sprain can be a mechanism for creating trigger point. Proper treatment of trigger points, in addition to preventing recurrence of sprains, may reduce pain and improve muscle function. This improvement can be the result of preserving the surrounding tissues from excessive pressure. OBJECTIVE Investigate the added value of dry needling into perturbation training protocol for chronic ankle sprain. DESIGN Randomized clinical trial; assessor-blind; before and after comparison. SETTING Treatment of patients referred to the institutional rehabilitation clinics. MAIN OUTCOME MEASURE(S) Functional assessment with FAAM questionnaire score, Pain with NPRS scale, ankle instability severity with Cumberland tool. METHODS Twenty-four patients with chronic ankle instability participated in this clinical trial and were randomly divided into two groups. Intervention was 12 sessions in which one group received only perturbation training and the other group received perturbation training along with dry needling. Repeated measures ANOVA was used to investigate the effect of treatment. RESULTS Data Analysis showed significant difference in NPRS and FAAM and Cumberland score before and after treatment in each group (P < 0.001). Comparison of the results between the groups did not show any significant difference (P > 0.05). CONCLUSION The findings showed that adding dry needling technique to the perturbation training does not have greater effects on the pain and function of patients with chronic ankle instability.

Abstract
BACKGROUND For the diagnosis of acute lateral ankle sprain, many clinicians use ultrasound; they typically focus on the lateral ligament complex, which is the most common site of lesions in ankle sprain. However, this approach risks missing other foot and ankle lesions. The present study aimed to provide and analyze the results of a new ultrasound method of diagnosis for acute lateral ankle sprain which can thoroughly investigate overall lesions of the foot and ankle. METHODS Retrospective cross-sectional cohort study of 123 patients who underwent diagnostic ultrasound within 1 week of acute lateral ankle injury was performed. Causes of ankle sprain, incidence and severity of each ligament injury, location of anterior talofibular ligament (ATFL) injury, accompanying ligament injury, and occult fracture were analyzed. RESULTS Among the 102 cases of ATFL injuries, 60 (58.5%) had islolated ATFL injury, 28 (27.5%) had accompanying calcaneofibular ligament injury (CFL), and 14 (13.7%) had accompanying midtarsal or syndesmosis injury. ATFL injuries occurred on the fibula attachment in 48 (47.1%) cases, ligament mid-substance in 24 (23.5%) cases, and talus attachment in 30 (29.4%) cases. Among the 165 lesions from 123 cases, injuries of the fourth or fifth dorsal tarsometatarsal (12 cases, 7.3%), bifurcate (11 cases, 6.7%), and anterior tibiofibular (11 cases, 6.7%) ligaments were not rare. CONCLUSION These findings suggest that an ultrasound examination involving investigation of the midtarsal joint and syndesmotic ligament, as well as the ATFL and CFL, is useful for comprehensive, systemic diagnosis of acute lateral ankle sprain.

Abstract
It remains unclear how unexpected perturbations during single-leg landings affect lower extremity kinematics and muscle activations in patients with chronic ankle instability (CAI). The purpose of this study was to identify the differences in lower extremity movement patterns among CAI subjects, copers, and healthy controls. Sixty-six people including 22 CAI subjects, 22 copers, and 22 healthy controls volunteered to participate in the study. Lower extremity joint kinematics and EMG activations from 200-ms pre to 200-ms post the initial contact during unexpected tilted landings were measured. Functional data analysis was used to evaluate between-group differences for outcome measures. Relative to copers and healthy controls, CAI subjects showed more inversion from 40-ms to 200-ms after initial contact. Relative to healthy controls, CAI subjects and copers showed more dorsiflexion. Relative to healthy controls, CAI subjects and copers showed more muscle activation in tibialis anterior and peroneus longus, respectively. In conclusion, CAI subjects demonstrated greater inversion angles and muscle activation before initial contact compared to LAS copers and healthy controls. This suggests that CAI subjects and copers prepare for their landing with protective movements, but the prepared movements shown by CAI subjects may be insufficient to reduce risk of recurrent injury.

Abstract
Ankle microinstability results from the superior fascicle of anterior talofibular ligament (ATFL) injury and is a potential cause of chronic pain and disability after an ankle sprain. Ankle microinstability is usually asymptomatic. When symptoms appear, patients describe a subjective ankle instability feeling, recurrent symptomatic ankle sprains, anterolateral pain, or a combination of them. A subtle anterior drawer test can usually be observed, with no talar tilt. Ankle microinstability should be initially treated conservatively. If this fails, and because superior fascicle of ATFL is an intra-articular ligament, an arthroscopic procedure is recommended to address.

Abstract
The management protocol for each case of ankle sprain should be individualized and optimized in order to reduce the likelihood of development of chronic instability. Initial treatment aims to address pain, swelling, and inflammation and facilitates regaining pain-free joint motion. Short-term joint immobilization is indicated in severe cases. Subsequently, muscle strengthening, balance training, and targeted activities to develop proprioception are added. Gradually, sports-related activities are added with the ultimate goal of bringing the individual back to preinjury level of activity. This protocol of conservative treatment should always be offered before considering any surgical intervention.

Abstract
Despite the high frequency of ankle sprains, the ideal management is controversial, and a significant percentage of patients sustaining an ankle sprain never fully recover. There is strong evidence that residual disability of ankle joint injury is often caused by an inadequate rehabilitation and training program and early return to sports. Therefore, the athlete should start their criteria-based rehabilitation and gradually progress through the programmed activities, including cryotherapy, edema relief, optimal weight-bearing management, range of motion exercises for ankle dorsiflexion improvement, triceps surae stretching, isometric exercises and peroneus muscles strengthening, balance and proprioception training, and bracing/taping.

Abstract
Injuries of the medial ankle ligament complex (MALC; deltoid and spring ligament) are more common following ankle sprains than expected, especially in eversion-external rotation mechanisms. Often these injuries are associated with concomitant osteochondral lesions, syndesmotic lesions, or fractures of the ankle joint. The clinical assessment of the medial ankle instability together with a conventional radiological and MR imaging is the basis for the definition of the diagnosis and therefore the optimal treatment. This review aims to provide an overview as well as a basis to successfully manage MALC sprains.

Abstract
Lateral ankle ligament sprains and syndesmotic injuries are two different entities. However, they may be combined under the same spectrum depending on the arch of violence during the injury. Currently, the clinical examination has a limited value in the differential diagnosis between an acute anterior talofibular ligament rupture and a syndesmotic high ankle sprain. However, its use is indispensable for raising a high index of suspicion for detecting these injuries. Based on the mechanism of injury, clinical examination plays an essential role in guiding further imaging and early diagnosis of low/high ankle instability.

Abstract
Acute ankle sprains are common sports injuries. MRI is the most accurate test for assessing the integrity and severity of ligament injuries in acute ankle sprains. However, MRI may not detect syndesmotic and hindfoot instability, and many ankle sprains are treated conservatively, questioning the value of MRI. In our practice, MRI adds value in confirming the absence or presence of ankle sprain-associated hindfoot and midfoot injuries, especially when clinical examinations are challenging, radiographs are inconclusive, and subtle instability is suspected. This article reviews and illustrates the MRI appearances of the spectrum of ankle sprains and associated hindfoot and midfoot injuries.

Abstract
Ankle sprain and chronic lateral ankle instability are complex conditions and challenging to treat. Cone beam weight-bearing computed tomography is an innovative imaging modality that has gained popularity, with a body of literature reporting reduced radiation exposure and operating time, and shortened examination time and a decreased time interval between injury and diagnosis. In this article, we make clearer the advantages of this technology and encourage researchers to investigate the area, and clinicians to use it as a primary mode of investigation. We also present clinical cases provided by the authors to illustrate those possibilities using advanced imaging tools.

The role of sural nerve reflexes during drop-landing in subjects with and without chronic ankle instability. Exp Brain Res 2023; 241:1691-1705.

Abstract
The purpose of this study was to investigate the functional role of cutaneous reflexes during a single-leg drop-landing task among healthy, neurologically intact adults, and to identify whether individuals with chronic ankle instability (CAI) demonstrate altered reflexes and subsequent ankle kinematics. All subjects were physically active adults and were categorized as control (n = 10, Male = 6, Female = 4) or CAI (n = 9, Male = 4, Female = 5) depending on whether they scored a 0 or ≥ 11 on the Identification of Functional Ankle Instability questionnaire, respectively. Subjects performed 30-40 single-leg drop-landing trials from a platform set to the height of their tibial tuberosity. Muscle activity of four lower leg muscles was collected via surface electromyography, while ankle kinematics were recorded via an electrogoniometer. Non-noxious stimulations were elicited randomly to the ipsilateral sural nerve at two unique phases of the drop-landing task (takeoff and landing). Unstimulated and stimulated trials were used to calculate middle latency reflex amplitudes (80-120 ms) and net ankle kinematics (140-220 ms) post-stimulation. Mixed-factor ANOVAs were used to identify significant reflexes within groups and differences in reflex amplitudes between groups. Unlike the CAI group, the control group experienced significant facilitation of the Peroneus Longus (PL) and inhibition of the Lateral Gastrocnemius (LG) when stimulated at takeoff, resulting in eversion immediately prior to landing. When stimulated at landing, the control group experienced significantly more inhibition of the PL compared to the CAI group (p = 0.019). These results suggest lower neural excitability for individuals with CAI, which may predispose them to recurrent injury during similar functional tasks.

Abstract
BACKGROUND Grade III ankle sprains that fail conservative treatment can require surgical management. Anatomic procedures have been shown to properly restore joint mechanics, and precise localization of insertion sites of the lateral ankle complex ligaments can be determined through radiographic techniques. Ideally, radiographic techniques that are easily reproducible intraoperatively will lead to a consistently well-placed CFL reconstruction in lateral ankle ligament surgery. PURPOSE To determine the most accurate method to locate the calcaneofibular ligament (CFL) insertion radiographically. METHODS MRIs of 25 ankles were utilized to identify the "true" insertion of the CFL. Distances between the true insertion and three bony landmarks were measured. Three proposed methods (Best, Lopes, and Taser) for determining the CFL insertion were applied to lateral ankle radiographs. X and Y coordinate distances were measured from the insertion found on each proposed method to the three bony landmarks: the most superior point of the postero-superior surface of the calcaneus, the posterior most aspect of the sinus tarsi, and the distal tip of the fibula. X and Y distances were compared to the true insertion found on MRI. All measurements were made using a picture archiving and communication system. The average, standard deviation, minimum, and maximum were obtained. Statistical analysis was performed using repeated measures ANOVA, and a post hoc analysis was performed with the Bonferroni test. RESULTS The Best and Taser techniques were found to be closest to the true CFL insertion when combining X and Y distances. For distance in the X direction, there was no significant difference between techniques (P = 0.264). For distance in the Y direction, there was a significant difference between techniques (P = 0.015). For distance in the combined XY direction, there was a significant difference between techniques (P = 0.001). The CFL insertion as determined by the Best method was significantly closer to the true insertion compared to the Lopes method in the Y (P = 0.042) and XY (P = 0.004) directions. The CFL insertion as determined by the Taser method was significantly closer to the true insertion compared to the Lopes method in the XY direction (P = 0.017). There was no significant difference between the Best and Taser methods. CONCLUSION If the Best and Taser techniques can be readily used in the operating room, they would likely prove the most reliable for finding the true CFL insertion.

Effects of eight week core stability training on stable- and unstable-surface on ankle muscular strength, proprioception, and dorsiflexion in athletes with chronic ankle instability. J Bodyw Mov Ther 2023; 34:6-12. [PMID: 37301558 DOI: 10.1016/j.jbmt.2023.04.005] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/30/2020] [Revised: 03/24/2022] [Accepted: 04/05/2023] [Indexed: 06/12/2023]
Abstract
BACKGROUND Chronic ankle instability (CAI) is a common injury among athletes. Research has reported reduced dorsiflexion range of motion, impairment of proprioception, and decreased muscle strength of the ankle in people with CAI. The aim of this research was to examine the effects of 8-week core stability training on stable and unstable surfaces on ankle muscular strength, proprioception, and dorsiflexion range of motion (ROM) in athletes with CAI. METHODS Thirty-six athletes with CAI (age 22.42 ± 2.76 years; height 169.11 ± 3.52 cm; weight 68.46 ± 2.75 kg) participated in this study. They were divided into three groups: unstable-surface group (UG) (n = 12), stable-surface group (SG) (n = 12), and control group (CG) (n = 12). The UG and SG performed the core stability exercise protocol for 8 weeks, 3 sessions per week. The CG received their usual care and daily activities. Outcomes were measured pre-sessions and post-sessions. RESULTS The peak torque showed significant increases in the UG and SG compared with the CG during plantar flexion, dorsiflexion, inversion, and eversion (P < 0.05). There were also significant increases in UG compared with SG (P < 0.05). The proprioception showed significant decreases in UG compared with SG and CG (P < 0.05). The dorsiflexion ROM showed significant increases in UG and SG compared with CG. There were also significant increases in UG compared with SG (P < 0.05). CONCLUSIONS It seems that core stability exercises on trampoline surface helps improve the measured parameters in athletes with ankle instability. Therefore, this type of training is recommended as a therapeutic option for Individuals with CAI.

Surgical outcome of avulsion fractures of the distal fibula: a systematic literature review. Arch Orthop Trauma Surg 2023; 143:1275-1291. [PMID: 34820695 DOI: 10.1007/s00402-021-04256-6] [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: 09/15/2021] [Accepted: 11/11/2021] [Indexed: 11/25/2022]
Abstract
PURPOSE To provide a systematic overview of clinical and radiographic outcomes in patients who underwent surgical treatment of a painful avulsion fragment of the distal fibula also known as posttraumatic os subfibulare. METHODS A systematic literature search across two major sources (PubMed and Scopus) was performed. Twenty-seven studies were included and analyzed using the modified Coleman score to assess the methodologic quality. RESULTS The surgical treatment of symptomatic os subfibulare, with or without concomitant ankle instability, generally results in substantial improvement in clinical and radiographic outcomes with relative low complication rates. Clinical outcome measures may not be affected by the presence of ankle instability or by the fragment size. The methodological quality of analyzed studies was satisfactory. CONCLUSION Posttraumatic os subfibulare may result in chronic pain and ankle instability. If surgery is indicated, ankle instability should be concomitantly addressed when present. Based on available literature, satisfactory postoperative outcomes can be reliably expected following surgical treatment.

Ankle instability as a prognostic factor associated with the recurrence of ankle sprain: A systematic review. Foot (Edinb) 2023; 54:101963. [PMID: 36709590 DOI: 10.1016/j.foot.2023.101963] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/17/2022] [Accepted: 01/16/2023] [Indexed: 01/19/2023]
Abstract
DESIGN Systematic review using PRISMA guidelines. PURPOSE To explore Relationship between ankle instability and ankle sprain recurrence in preventing recurrence of ankle sprains and to provide appropriate treatment. METHODS MEDLINE (the Cochrane Library) and the Physiotherapy Evidence Database (PEDro) were explored using key words related to ankle instability and ankle sprains in for April 2022. According to the inclusion criteria, studies that 1) targeted patients with ankle sprains, 2) assessed ankle instability, and 3) investigated ankle sprain recurrence rates, were extracted. The author names, publication year, patient characteristics, comparison groups, intervention methods, and outcome data (ankle instability and recurrence) were extracted. A correlation analysis between recurrence rate and ankle instability was conducted. In addition, A meta-analysis was performed on the correlation coefficients within each article. RESULTS Eight studies were extracted from 149 studies. A correlation analysis was conducted on five studies and meta-analysis was on three studies with the same post-intervention follow-up period and the same assessment methods for ankle instability and recurrence rate. Strong positive correlations were found for the same follow-up periods (r = 0.95: 95%CI [0.62-0.99]; 3-month, r = 0.97: 95%CI [0.75-0.10]; 1 year, p < .05). The correlation became stronger as the follow-up period increased. Furthermore, the meta-analysis showed that ankle instability as well as the main symptoms of sprain, such as pain and swelling, tended to be positively correlated with the recurrent rate of ankle sprains. These results suggest that ankle instability is strongly related to recurrence, and the longer the time since onset, the stronger the relationship. CONCLUSIONS Ankle instability was a prognostic factor associated with recurrence of ankle sprains in patients with ankle sprains. Therefore, ankle instability is one of important factor in preventing recurrence of ankle sprains.

Abstract
Chronic ankle instability (CAI) is common, disabling, and represents a significant socioeconomic burden. Current treatment options are not adequately efficacious. CAI is multifaceted, yet it is commonly addressed in terms of either mechanical instability or functional impairment. Both are inherently linked. Basic research must be conducted to foster reliable translational research encompassing both mechanical and functional aspects. A review was conducted to identify CAI risk factors for inclusion in future studies, and we offer here opinions and perspectives for future research.

The effects of neuromuscular electrical stimulation to the ankle pronators on neural excitability & functional status in patients with chronic ankle instability. Phys Ther Sport 2023; 60:1-8. [PMID: 36634453 DOI: 10.1016/j.ptsp.2022.12.001] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2022] [Revised: 11/30/2022] [Accepted: 12/01/2022] [Indexed: 12/13/2022]
Abstract
OBJECTIVES Chronic ankle instability (CAI) is associated with decreased neural excitability that negatively impacts function. This study assessed a 2-week neuromuscular electrical stimulation (NMES) or transcutaneous electrical nerve stimulation (TENS) intervention over the ankle pronators on neural excitability, performance, and patient-reported function in patients with CAI. STUDY DESIGN Randomized controlled trial. PARTICIPANTS Twenty participants with CAI completed the study. MAIN OUTCOME MEASURES Participants were assessed for reflexive and corticospinal excitability to the ankle muscles, dynamic balance, side-hop test performance and patient-reported outcomes at baseline, post-intervention (2-weeks), and retention (4-weeks). Between baseline and post-intervention, participants reported for 5 sessions where they received either sub-noxious NMES (n = 11) or sensory-level TENS (n = 9) over the ankle pronators. RESULTS Improved reflexive excitability to the ankle pronators was observed in TENS at post-intervention (p = 0.030) and retention (p = 0.029). Cortical excitability to the dorsiflexors increased in TENS at post-intervention (p = 0.017), but not at retention (p = 0.511). No significant changes were found for other neural measures, balance ability, hopping, or patient-reported function (p > 0.050). CONCLUSIONS Our results suggest TENS modified neural excitability; however, these changes were not enough to impact clinical function. While TENS may be capable of neuromodulation, it may require rehabilitative exercise to generate lasting changes. NCT04322409. LEVEL OF EVIDENCE Level 2.

Abstract
OBJECTIVE To investigate the association between sex, self-reported ankle function, pain intensity, kinesiophobia, and perceived ankle instability in athletes with chronic ankle instability (CAI). DESIGN Cross-Sectional Study. SETTING University. PARTICIPANTS College club sports athletes with CAI (n = 42). MAIN OUTCOME MEASURES Relationships with the Cumberland Ankle Instability Tool (CAIT) score and the Tampa Scale for Kinesiophobia-11 (TSK-11), the Foot and Ankle Ability Measure (FAAM), sex (0: male, 1: female), and ankle pain intensity by the Numeric Rating Scale were explored with multiple regression analysis. RESULTS The regression model explained 50.3% of the variance of the CAIT score (P < 0.001), and the TSK-11 score (B = -0.382, P = 0.002), the FAAM sports subscale score (B = 0.122, P = 0.038), and sex (B = -2.646, P = 0.031) were significant independent variables for the CAIT score (P < 0.001), while pain intensity was not significant (B = -0.182, P = 0.504). These results indicated that higher TSK-11 score, lower FAAM sports subscale score, and being female were related to lower CAIT score. CONCLUSIONS Kinesiophobia related to perceived instability along with self-reported function and sex in athletes with CAI. Clinicians should assess the psychological aspects of athletes with CAI.

Abstract
OBJECTIVE To analyze the compatibility regularities of acupoints and the application characteristics of needling-moxibustionmethods in the treatment of ankle sprain by using complex network technology, so as to provide the basis and treatment ideas. METHODS The clinical research articles on acupuncture treatment of ankle joint sprain published from November 2011 to November 2021 were retrieved from databases of CNKI, Wanfang Data knowledge service platform, VIP information Chinese journal service platform and PubMed by using key words of "acupuncture""moxibustion" "acupuncture and moxibustion" "ankle injury" "ankle sprain" "injured ankle" and "syndesmotic injuries". After screening these articles according to our inclusion and exclusion criteria, a database of acupuncture treatment of ankle sprain was established. Then, analysis on the occurrence frequency of acupoints and their related meridians, and methods of needling manipulation, and the association rule analysis (quantitative analysis) about the closeness between acupoints, and the degree of support and confidence coefficient were conducted for acquiring the acupoint combinations with higher correlation in the compatibility using Apriori algorithm after modeling (with IBM SPSS Modeler18.0 software). Gephi 0.9.2 software was used to make complex network analysis, for which "k-core hierarchical analysis" and "community analysis" were used as the methods to analyze the network structure of acupoints, and the confidence value was used as the index to measure the importance of acupoints. RESULTS A total of 201 articles meeting the criteria were collected, including 196 articles in Chinese and 5 in English. A total of 236 acupuncture prescriptions were extracted, involving 61 acupoints, with a total frequency of occurrence being 846. The top 10 acupoints were Ashi point, Kunlun (BL60), Jiexi (ST41), Qiuxu (GB40), Shenmai (BL62), Yanglingquan (GB34), Taixi (KI3), Zhaohai (KI6), Xuanzhong (GB39) and Shangqiu (SP5), with the occurrence frequency being 109, 79, 70, 68, 63, 59, 53, 52, 37 and 34, respectively. The results of descriptive analysis showed that the top 5 meridians were Gallbladder Meridian of Foot-shaoyang, Bladder Meridian of Foot-taiyang, Kidney Meridian of Foot-shaoyin, Stomach Meridian of Foot-yangming and Spleen Meridian of Foot-taiyin, with the frequency being 181, 153, 116, 105 and 53, respectively. Complex network analysis displayed that after "k-core hierarchical analysis" and "Community division", two communities were reserved, mainly involving 15 core acupoints such as Ahshi point, GB40, ST14, BL62, GB34, KI6, BL60, KI3, GB39, Zusanli (ST36), SP5; Taichong (LR3), Zulinqi (GB41), Sanyinjiao (SP6) and Rangu (KI2). The results of association rule analysis showed that the most relevant acupoint combination is "BL60-ST41" (support degree 34.83%), followed by "BL60-KI3" (support degree 26.37%), reflecting the principle of selection of local acupoint for ankle sprain. The therapeutic methods are filiform needle acupuncture, and the reducing technique and uniform reinforcing and reducing manipulation are the most commonly used approaches, but the reinforcing method is rarely used. CONCLUSION In the treatment of ankle sprain, local acupoints and Ashi points are mainly used, in combination with reducing or uniform reinforcing and reducing manipulations, as well as the method of needling and moxibustion, which provides a good reference for clinical practice.

Mouse model of subtalar post-traumatic osteoarthritis caused by subtalar joint instability. J Orthop Surg Res 2022; 17:537. [PMID: 36510269 PMCID: PMC9743676 DOI: 10.1186/s13018-022-03435-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/26/2022] [Accepted: 12/05/2022] [Indexed: 12/14/2022] Open
Abstract
BACKGROUND Common ankle sprains are often accompanied by injury to the subtalar joint, which eventually leads to subtalar joint instability. Because the clinical manifestations for subtalar joint instability are similar to ankle joint injuries, these are often overlooked. This study aimed to establish an animal model of subtalar joint instability to study post-traumatic osteoarthritis of the subtalar joint caused by long-term subtalar joint instability and to provide a reference for future clinical research on chronic subtalar joint instability. METHODS In all, 24 C57BL/6 male mice were randomly divided into three groups: Sham, cervical ligament (CL) transection and CL + calcaneofibular ligament (CFL) transection groups. One week after surgical operation, all mice were trained to run in the mouse rotation fatigue machine every day. During this period, a balance beam test was used to evaluate the motor level and coordination ability of the mice before the operation and three days, one week, four weeks, eight weeks, and twelve weeks after operation. Further, post-traumatic osteoarthritis of the subtalar joint was quantified via micro-CT and histological staining. RESULTS The mice in the partial ligament transection group took significantly longer than those in the Sham group to pass through the balance beam and showed an increased number of hindfoot slips. Micro-CT analysis showed that the subtalar bone volume fraction in the CL + CFL transection group and CL transection group was 5.8% and 2.8% higher than that in the Sham group, respectively. Histological staining showed obvious signs of post-traumatic osteoarthritis (PTOA) in the subtalar joint of the ligament transection group. CONCLUSIONS The transection of CL and CL + CFL can cause instability of the subtalar joint in mice, resulting in a decrease in motor coordination, and long-term instability of the subtalar joint in mice can cause PTOA of the subtalar joint, which is manifested as destruction and loss of articular cartilage.

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
BACKGROUND This study aims to analyze the ligaments of the dorso-lateral calcaneo-cuboid joint and to assess the biomechanical relevance of the bifurcate ligament. METHODS 16 specimens were analyzed for their ligamentous anatomy of the dorso-lateral calcaneo-cuboid joint and side-alternating assigned to two groups with varying ligamentous dissection order. The Chopart joint was stressed in plantar, medial, and lateral direction measuring the displacement by an 3D motion tracker for every dissection step. RESULTS 37.5% of specimens had all ligaments (lateral calcaneo-cuboid, dorsal calcaneo-cuboid, bifurcate calcaneo-cuboid, bifurcate calcaneo-navicular), 37.5% were lacking bifurcate´s calcaneo-cuboid-portion, and 25% presented without dorsal calcaneo-cuboid. Biomechanical testing revealed no significant displacement within the calcaneo-cuboid or talo-navicular joint for any stressed state except for axial compression with dissected dorsal talo-navicular joint capsule in Group 2. CONCLUSION Broad morphological variability and missing significant displacement regardless of its integrity, make the bifurcate ligament appear of limited biomechanical relevance.

Abstract
BACKGROUND Arthroscopic debridement is a common surgical treatment for patients with anterolateral impingement (ALI) of the ankle. Although they often have a history of ankle sprain, information regarding the role of ankle instability in ALI is limited. The aims of this review were to: 1) assess the clinical outcomes of arthroscopic surgical treatment for ALI of the ankle; and 2) review the data regarding anterior talofibular ligament (ATFL) injury and lateral ankle instability in patients who underwent arthroscopic surgery for ALI. METHOD A literature search of Pubmed and EMBASE was performed. Studies that met the following inclusion criteria were reviewed: (1) human clinical studies investigating patients who underwent arthroscopic surgery for ALI; (2) results with at least one scoring system with minimum follow-up of six months. The quality of each study was evaluated using the Oxford CEBM tool to assess the level of evidence and the grade of recommendation. The data of patient characteristics, intraoperative findings and clinical outcomes were extracted. RESULTS Eight articles were included in this systematic review, all of which were graded level 4 with grade C recommendation. In total, 203 patients with a mean age of 32 years (ranging from 11 to 74) were analysed. AOFAS score was used in 6 studies and scored 90.1 on average at follow-up. Two other studies used original scores. One study reported arthroscopic findings of the ATFL and another study reported on residual instability after surgery. New ankle sprains during follow-up period were reported in 8.3 to 20.0% of patients in 4 studies. DISCUSSION This review showed good clinical results of arthroscopic debridement with a grade C recommendation. Reports regarding arthroscopic observation of the ATFL and residual instability after surgery were lacking. Further investigation of what we are still calling "ALI" should be made with higher level of evidence focusing more on ATFL injury and its effect on clinical outcomes.

Abstract
BACKGROUND A lateral ankle sprain (LAS) is the most common musculoskeletal injury in the physically active population. It is uncertain what percentage of these patients develop persisting symptoms including pain, recurrent sprains and subjective instability. This systematic review was conducted to assess the presence and duration of persistent symptoms after a first LAS. METHODS A systematic review of the Medline, Web of Sciences, Embase, CINAHL and Pedro databases was performed to identify peer-reviewed articles concerning the occurrence and duration of remaining symptoms after a first LAS. Inclusion criteria focused on selection of patients without previous ankle injuries and study quality. One of the following outcomes had to be described: subjective instability, resprains, remaining symptoms. RESULTS In total, 15 studies were included. The occurrence of patients with subjective instability decreased from 37.9% (95%CI [6.0-69.7]) at 3 months to 16.1% (95%CI [7.8-24.3]) at 6 months and 8.1% (95%CI [3.3-13.3]) at 12 months. The occurrence of patients with a recurrent LAS was 15.8% (95%CI [6.3-25.3]) at 12 months. The occurrence of patients with residual pain decreased from 48.6% (95%CI [23.6-73.5]) at 3 months, to 21.5% (95%CI [2.8-40.2]) at 6 months and 6.7% (95%CI [3.2-10.1]) at 12 months. CONCLUSION This study offers new insights in the presence of remaining symptoms after a first LAS and the development of chronic ankle instability. Twelve months following an initial LAS, a significant number of patients may still have symptoms. The incidence of subjective instability, and pain, continues to decrease until 12 months post-injury. This new information may suggest that a longer period of non-operative treatment may be warranted before recommending surgical intervention in patients with a first LAS.

Abstract
OBJECTIVES To determine whether collegiate dancers with chronic ankle instability (CAI) demonstrated impaired postural control during instrumented measures of single-leg static balance compared to dancers without CAI. DESIGN Cross sectional design. SETTING University dance studios. PARTICIPANTS We included N = 39 dance majors from a large, public university. We stratified participants into CAI (n = 20, age = 20 ± 1.8, IdFAI = 17.3 ± 5.7, number of sprains = 1.9 ± 1.1) and Control groups (n = 19, age = 20 ± 1.2, IdFAI = 2.5 ± 3.0). MAIN OUTCOME MEASURES Participants performed 3 x 10-s single-leg, static balance trials on a pressure mat in two different conditions, foot-flat eyes closed and demi-pointe eyes open. We measured six different time-to-boundary (TTB) measurements during each balance trial and calculated the average of the 3 trials for each condition. Participants also completed the Foot and Ankle Ability Measure (FAAM) sport and activities of daily living (ADL) questionnaires. RESULTS The CAI group reported greater IdFAI and lower FAAM-ADL and FAAM-Sport scores compared to the control group. We observed no significant differences in TTB measurements between the CAI and control groups during either balance conditions. CONCLUSIONS Instrumented measures of static postural control were not impaired in college dancers with CAI compared dancers without CAI.

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.

Lower limb kinematics during single leg landing in three directions in individuals with chronic ankle instability. Phys Ther Sport 2022; 57:71-77. [PMID: 35940084 DOI: 10.1016/j.ptsp.2022.07.011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2022] [Revised: 07/21/2022] [Accepted: 07/24/2022] [Indexed: 11/19/2022]
Abstract
OBJECTIVES To compare the lower limb kinematics of participants with chronic ankle instability (CAI) and healthy participants during forward, lateral, and medial landings. DESIGN Cross-sectional study. SETTING Laboratory. PARTICIPANTS Eighteen athletes with CAI and 18 control athletes. MAIN OUTCOME MEASURES Hip, knee, and ankle joint kinematics during forward, lateral, and medial single-leg landings were compared between the groups using two-way ANOVA for discrete values and statistical parametric mapping two-sample t-tests for time-series data. RESULTS The CAI group had significantly greater ankle dorsiflexion than the control group (P ≤ 0.013), which was observed from the pre-initial contact (IC) for lateral and medial landings and post-IC for forward landing. The CAI group showed greater knee flexion than the control group from the IC for lateral landing and post-IC for forward landing (P ≤ 0.014). No significant differences in ankle inversion kinematics were found between the CAI and control groups. Lateral landing had a greater peak inversion angle and velocity than forward and medial landings (P < 0.001). Medial landing had a greater inversion velocity than forward landing (P < 0.001). CONCLUSIONS This study suggests that individuals with CAI show feedforward protective adaptations in the pre-landing phase for lateral and medial landings.

Major change in morphology of the talofibular ligaments during fetal development and growth. SURGICAL AND RADIOLOGIC ANATOMY : SRA 2022; 44:1121-1129. [PMID: 35857084 DOI: 10.1007/s00276-022-02987-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/01/2022] [Accepted: 07/08/2022] [Indexed: 10/17/2022]
Abstract
BACKGROUND AND PURPOSE Ankle sprain is often attributed to damage of the anterior and posterior talofibular ligaments (ATFL, PTFL). We compared the morphology of these ligaments in fetuses of different gestational ages (GAs) with the horizontal configuration in adults. MATERIALS AND METHODS Histological sections of unilateral ankles were examined in 22 fetuses, 10 at GA of 9-12 weeks and 12 at GA of 26-39 weeks. RESULTS At a GA of 9 to 10 weeks, the ATFL and PTFL consisted of horizontally running straight fibers. The initial ATFL appeared as a thickening of the capsule of the talocrural joint, although the initial PTFL was distant from this joint. Until a GA of 12 weeks, the talus and fibula were separated by an expanding joint cavity. Thus, the initial horizontal ligaments were "pulled" in a distal direction. The distal parts of the ligaments consisted of thin collagenous fibers that had an irregular array, whereas the short proximal parts had thick fibers and a horizontal array. In near-term fetuses, the ligaments contained no horizontal fibers. The ATFL had a wavy course around the thick synovial fold, and was exposed to the joint cavity along the entire course; the distal part was thinner than the proximal part. The PTFL was bulky and consisted of fibers with an irregular array. Therefore, the morphology in a near-term fetus was quite different from that in adults. CONCLUSION The horizontal and straight composite ankle fibers in adults apparently result from postnatal reconstruction, depending on mechanical demand.

Ultrasound findings of the deltoid ligament in patients with acute ankle sprains: A retrospective review. J Orthop Sci 2022:S0949-2658(22)00130-0. [PMID: 35691876 DOI: 10.1016/j.jos.2022.05.010] [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: 02/15/2022] [Revised: 03/31/2022] [Accepted: 05/11/2022] [Indexed: 10/18/2022]
Abstract
BACKGROUND The deltoid ligament is a complex structure composed of multiple ligaments located on the medial side of the ankle joint that can be injured by ankle sprains. Although there have been previous reports on ultrasound imaging of the injured deltoid ligament, a systematic method for depicting each ligament component has not been established. This study aimed to clarify the ultrasound findings of the deltoid ligament in ankle sprains using a systematic scanning protocol. METHODS We examined the tenderness of the medial ankle and evaluated the ultrasound findings of the deltoid ligament in 169 sprained ankles with no fracture, within 3 days after injury. Observation and evaluation of the six components of the deltoid ligament were performed using a systematic scanning protocol with four probe positions. RESULTS Of the 169 ankles, 48 ankles had tenderness in the deltoid ligament. Ultrasonography confirmed deltoid ligament damage in 13 of these 48 ankles. Of the 13 ankles, 3 ankles had damages only in the superficial layer, 3 ankles only in the deep layer, and 7 ankles in both the superficial and deep layers. CONCLUSIONS We clarified the details of the damage pattern of the deltoid ligament in acute ankle sprains. It was possible to identify the superficial and deep layers of the ligament and to observe the damage pattern of each ligament component in detail, and it appeared that ultrasonography could be used as a tool to evaluate the damage pattern of the deltoid ligament in acute ankle sprains.

The L-shaped tunnel technique showed favourable outcomes similar to those of the Y-graft technique in anatomic lateral ankle ligament reconstruction. Knee Surg Sports Traumatol Arthrosc 2022; 30:2166-2173. [PMID: 35217882 DOI: 10.1007/s00167-022-06880-0] [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: 07/27/2021] [Accepted: 01/13/2022] [Indexed: 01/19/2023]
Abstract
PURPOSE To compare the mid- to long-term clinical and radiological outcomes of the confluent L-shaped tunnel technique with the Y-graft technique for anatomic lateral ankle ligament reconstruction. METHODS This retrospective study involved 41 patients who underwent lateral ankle ligament reconstruction between 2013 and 2018. Based on the tunnel direction and tendon fixation method at the fibula side, patients were divided into two groups, with 17 patients in the L-shaped tunnel group and 24 patients in the Y-graft group. The American Orthopaedic Foot and Ankle Society (AOFAS) score, visual analogue scale (VAS) pain score, Tegner score, and Karlsson score were evaluated and compared preoperatively and at follow-up. Anterior talar translation and talar tilt at stress radiographs, postoperative sprain recurrence, range of motion (ROM) restriction, sensory disturbance, etc., were also collected and compared. RESULTS The mean follow-up times were 72 and 42 months for the L-shaped group and Y-graft group, respectively. The median VAS pain score, Tegner score, AOFAS score, Karlsson score significantly improved from a preoperative level in both groups (all with p < 0.01). No significant difference was found between the two groups regarding the changes from preoperatively to postoperatively except for the VAS pain score reduction (1.58 ± 1.58 in the L-shaped group vs. 2.53 ± 1.29 in the Y-graft group, p = 0.035). The incidence of flexion-extension ROM restriction (≥ 5°) was significantly higher in the Y-graft group (41.2%) than in the L-shaped group (12.5%) (p = 0.035). CONCLUSIONS Both the confluent L-shaped tunnel technique and the Y-graft technique significantly improved symptoms, ankle function, and radiographic outcomes in patients with chronic lateral ankle instability (CLAI) at mid- to long-term follow-up. The confluent L-shaped tunnel technique resulted in lower rates of flexion-extension ROM restriction, while the Y-graft technique showed better VAS pain reduction. This result could provide further evidence for the surgical treatment of CLAI. LEVEL OF EVIDENCE III.

Electronic Method (Pro-Kin) for Improving And Speeding up The Recovery after Ankle Sprain. Endocr Metab Immune Disord Drug Targets 2022; 22:EMIDDT-EPUB-123881. [PMID: 35616674 DOI: 10.2174/1871530322666220523155452] [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: 01/14/2021] [Revised: 05/07/2021] [Accepted: 05/18/2021] [Indexed: 11/22/2022]
Abstract
BACKGROUND AND OBJECTIVE Ankle sprains, very common injuries occurred especially during sports activities, are mainly caused by indirect trauma, which influences exaggerated stress exceeding the strength of stabilization mechanisms. Up to 85% of such injuries result from a sudden flexion and inversion of the foot. In this study, we analyzed the effectiveness of the platform Pro-kin, an innovative system that has given us the possibility to combine the functionality of the older proprioceptive boards with very accurate software in order to improve and accelerate the recovery after ankle injuries. METHODS 30 patients with moderate ankle sprain outcomes in two groups (A and B) were included in this study. Group A was only treated with proprioceptive exercises for 3 weeks, while the group B was trained with the innovative Pro-kin. In both groups, we evaluated VAS scale, the ratio between the number of circumductions performed by the injured foot and the time spent on doing them and the percentage of load among the injured and the healthy foot in statics and dynamics with electronic baropodometry. Our data has been collected at t0 (beginning of study), t1(one week later), t2 (two weeks later), t3 (one month later), t4 (two months later), and then analyzed by the two-way analysis of variance (2-way ANOVA) test. RESULTS At t0 no statistical differences of pain in the 2 groups (3.3 and 3.4); the values were similar, as well as at time t1, t2, t3 and t4. Therefore we deduce that Pro-kin treatment is not painful. The number of circumductions performed was definitely better in B group since the first week; for the A group the values considerably increased only at t3 (one month later). Comparing the load percentages on two feet detected by the electronic baropodometer in statics and in dynamics, we deduced that the patients of A group tend to lean mostly on the healthy foot than B group. CONCLUSIONS This study demonstrates that new technological resources (such as Pro-kin) may be helpful to improve and speed up the recovery of ankle sprain in athletes.
