Abstract
Cartilage lesions to the ankle joint are common and can result in pain and functional limitations. Surgical treatment aims to restore the damaged cartilage's integrity and quality. However, the current evidence for establishing best practices in ankle cartilage repair is characterized by limited quality and a low level of evidence. One of the contributing factors is the lack of standardized preoperative and postoperative assessment methods to evaluate treatment effectiveness and visualize repaired cartilage. This review article seeks to examine the importance of preoperative imaging, classification systems, patient-reported outcome measures, and radiological evaluation techniques for cartilage repair surgeries.

Abstract
BACKGROUND Osteochondral lesions of the talus (OLTs) are among the common sports-related injuries. However, there are few reports on the return to sports after OLT surgery in skeletally immature children. This study was performed to evaluate the return to sports after microfracture for OLTs in skeletally immature children. METHODS This study involved 17 ankles of 16 patients (mean age, 13.2 years; range, 10-16 years) with open tibial epiphyses on magnetic resonance imaging (MRI) who underwent microfracture for OLTs <10 mm in diameter and confirmation of lesion instability under arthroscopy. Nine of 17 ankles had additional lateral ankle ligament stabilization. All patients were participating in some form of sports. The Japanese Society for Surgery of the Foot (JSSF) score, Ankle Activity Score (AAS), return to sports rate, lesion size, grade of subchondral bone marrow edema, and Magnetic Resonance Observation of Cartilage Repair Tissue (MOCART) score on MRI were evaluated after microfracture. The mean postoperative follow-up period was 53.5 months. RESULTS The mean JSSF score significantly improved from 76.1 points preoperatively to 94.9 points at the final follow-up (P < .01). The mean AAS showed no change from preoperative state to final follow-up. The return to sports rate was 100%. The lesion size significantly decreased from 76.3 to 56.7 mm2 in area (P = .02) and from 283.2 to 185.6 mm3 in volume (P = .05). The bone marrow edema grade decreased in 8 of 17 ankles. The total MOCART score showed a significant improvement from 6 months to 1 year postoperatively (P = .05). CONCLUSION All skeletally immature children who underwent microfracture for OLTs in this study were able to return to sports activity and showed improvements in clinical scores and MRI parameters. Microfracture may be considered an effective first-line treatment for OLTs <10 mm in diameter in skeletally immature athletes. LEVEL OF EVIDENCE Level IV, retrospective case-control study.

Concomitant Subchondral Bone Cysts Negatively Affect Clinical Outcomes Following Arthroscopic Bone Marrow Stimulation for Osteochondral Lesions of the Talus. Arthroscopy 2023; 39:2191-2199.e1. [PMID: 37105367 DOI: 10.1016/j.arthro.2023.03.029] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/28/2022] [Revised: 03/11/2023] [Accepted: 03/23/2023] [Indexed: 04/29/2023]
Abstract
PURPOSE To study the effects of concomitant subchondral bone cysts (SBCs) on prognosis after arthroscopic bone marrow stimulation (BMS) for osteochondral lesions of the talus (OLTs) less than 100 mm2 and to further assess the correlation between cystic OLT area, depth, or volume and postoperative outcomes. METHODS We retrospectively analyzed consecutive patients with OLTs (<100 mm2) who received BMS between April 2017 and May 2020 with a minimum follow-up of 24 months. Lesion area, depth, and volume were collected on preoperative magnetic resonance imaging. Visual analog scale (VAS), American Orthopedic Foot and Ankle Society, Karlsson-Peterson, Tegner, Foot and Ankle Ability Measure (FAAM)-Activities of Daily Life and Sports scores were assessed before surgery and at the latest follow-up. Additionally, a general linear model (GLM) and a Pearson correlation analysis (PCA) were performed to investigate the effects of concomitant cysts on postoperative results. RESULTS Eighty-two patients with a mean follow-up of 39.22 ± 12.53 months were divided into non-cyst (n = 45; 39.91 ± 13.03 months) and cyst (n = 37; 38.37 ± 12.02 months) groups. There was no significant difference in the OLT area between the non-cyst and cyst groups (46.98 ± 19.95 mm2 vs 56.08 ± 22.92 mm2; P = .093), but the cyst group showed significantly greater depth (6.06 ± 1.99 mm vs 3.96 ± 1.44 mm; P = .000) and volume (248.26 ± 156.81 mm3 vs 134.58 ± 89.68 mm3; P = .002). The non-cyst group showed significantly more improvement in VAS pain, Karlsson-Peterson, Tegner, and FAAM scores than the cyst group (P < .05). The GLM indicated that SBCs negatively affected VAS pain and Tegner scores (P < .05). For OLTs with cysts, the PCA showed that an area of 90.91 mm2, depth of 7.56 mm, and volume of 428.13 mm3 were potential cutoff values associated with poor outcomes. CONCLUSIONS The concomitant SBCs negatively affected the prognosis of OLTs after BMS. For OLTs with cysts, an area of 90.91 mm2, depth of 7.56 mm, and volume of 428.13 mm3 were the potential cutoff values associated with poor outcomes after BMS. LEVEL OF EVIDENCE Level III, retrospective comparative study.

Abstract
Background: Magnetic resonance imaging (MRI) is commonly used for evaluation of ankle cartilage repair, yet its association with clinical outcome is controversial. This study analyzes the correlation between MRI and clinical outcome after cartilage repair of the talus including bone marrow stimulation, cell-based techniques, as well as restoration with allo- or autografting. Methods: A systematic search was performed in MEDLINE, Embase, and Cochrane Collaboration. Articles were screened for correlation of MRI and clinical outcome. Guidelines of Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) were used. Chi-square test and regression analysis were performed to identify variables that determine correlation between clinical and radiologic outcome. Results: Of 2687 articles, a total of 43 studies (total 1212 cases) were included with a mean Coleman score of 57 (range, 33-70). Overall, 93% were case series, and 5% were retrospective and 2% prospective cohort studies. Associations between clinical outcome and ≥1 imaging variable were found in 21 studies (49%). Of 24 studies (56%) using the composite magnetic resonance observation of cartilage repair tissue (MOCART) score, 7 (29%) reported a correlation of the composite score with clinical outcome. Defect fill was associated with clinical outcome in 5 studies (12%), and 5 studies (50%) reported a correlation of T2 mapping and clinical outcome. Advanced age, shorter follow-up, and larger study size were associated with established correlation between clinical and radiographic outcome (P = .021, P = .028, and P = .033). Conclusion: Interpreting MRI in prediction of clinical outcome in ankle cartilage repair remains challenging; however, it seems to hold some value in reflecting clinical outcome in patients with advanced age and/or at a shorter follow-up. Yet, further research is warranted to optimize postoperative MRI protocols and assessments allowing for a more comprehensive repair tissue evaluation, which eventually reflect clinical outcome in patients after cartilage repair of the ankle. Level of Evidence: Level III, systematic review and meta-analysis.

Abstract
Background Traditional medial malleolar osteotomy combined with autologous osteochondral transplantation (AOT) is mostly used in the treatment of osteochondral lesions of the talus (OLTs), but with high osteotomy and donor site complications. We hypothesis a new triplane medial malleolar osteotomy combined with AOT from non-weight-bearing area of the talus could be a promising choice for OLTs. Methods We reviewed all the symptomatic OLTs patients who received AOT with triplane osteotomy of the medial malleolus between September 2015 and December 2017 in our department. According to the inclusion and exclusion criteria, 23 patients (23 ankles), including 14 males and 9 females, were included in the study. The mean age was 35.6 years. The mean size of the lesion area was 141.5 mm2. According Ferkel’s classification, including 5 type I, 11 typeIIa and 7 typeIIb. The visual analog scale (VAS) for pain during walking and the American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score were used for the pre- and postoperative evaluations. In addition, the incorporation of the grafts was assessed by computed tomography (CT). Results All patients had a minimum follow-up of 22 months, with an average of 37.1 months. The mean time from osteotomy to full weight-bearing activity was 8.1 ± 2.3 weeks (range, 5–12 weeks). The mean VAS score improved from 5.6 ± 0.7 preoperatively to 0.7 ± 1.0 postoperatively (P < 0.01). The AOFAS ankle-hindfoot score improved significantly in all domains (P < 0.01). Twenty-one patients returned to sport at their previous level, and 2 returned at a lower level compared with preinjury (mean return to play, 7.4 months). According to CT, the medial malleolus recovered in all patients, and the graft was incorporated well. One patient suffered from flexor hallucis longus tendon discomfort due to internal fixation screw irritation posteromedial to the ankle. The general complication rate was 4.3% (1/23). Conclusions These results indicate that AOT combined with medial malleolus triplane osteotomy maybe a viable option for OLTs. Patients could perform weight-bearing exercise and return to sport as early as possible, with a lower rate of complications at the osteotomy site and donor site. However, the large sample well-designed prospective comparative studies are still needed.

Clinical outcomes after arthroscopic microfracture for osteochondral lesions of the talus are better in patients with decreased postoperative subchondral bone marrow edema. Knee Surg Sports Traumatol Arthrosc 2021; 29:1570-1576. [PMID: 33009941 DOI: 10.1007/s00167-020-06303-y] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/01/2020] [Accepted: 09/22/2020] [Indexed: 10/23/2022]
Abstract
PURPOSE Magnetic resonance imaging (MRI) findings of subchondral bone marrow edema (SBME) in osteochondral lesions of the talus (OLT) after arthroscopic microfracture are associated with poor clinical outcomes. However, the relationship between SBME volume change and clinical outcomes has not been analyzed. It was hypothesized that clinical outcomes correlated with SBME volume change and extent of cartilage regeneration in patients with OLT. METHODS 64 patients who underwent arthroscopic microfracture for OLT were followed up for more than 2 years. SBME volume change was measured by comparing preoperative and 2-year follow-up MRI. Clinical outcomes were assessed using the visual analogue scale (VAS) and the American orthopedic foot and ankle society ankle-hindfoot scale (AOFAS) at the 2-year and final follow-up. To compare clinical outcomes, patients were categorized into two groups: decreased SBME (DSBME) group (cases without SBME on either MRI or with a decreased SBME volume between the MRIs) and increased SBME (ISBME) group (cases with new SBME on postoperative MRI or with an increased SBME volume between the MRIs). Additionally, the effects of age, sex, body mass index, symptom duration, OLT size, OLT location, containment/uncontainment, preoperative subchondral cysts, pre- and postoperative SBME volumes, and MRI observation of cartilage repair tissue score on clinical outcomes were analyzed. RESULTS The DSBME group included 45 patients, whereas the ISBME group included 19. The mean age was 40.1 ± 17.2 years, and mean follow-up period was 35.7 ± 18.3 months. Preoperative SBME volume was significantly higher in the DSBME group, while the ISBME group had higher volumes at the final follow-up. In both groups, the VAS and AOFAS scores significantly improved at the final follow-up (p < 0.001, < 0.001). The VAS scores were significantly lower in the DSBME group at the 2-year and final follow-up (p = 0.004, 0.011), while the AOFAS scores were significantly higher (p = 0.019, 0.028). Other factors including cartilage regeneration did not affect clinical outcomes. CONCLUSION SBME volume change correlated with clinical outcomes after arthroscopic microfracture for OLT. Clinical outcomes were worse in patients with new postoperative SBME and increased postoperative SBME volume. In patients with an unsatisfactory clinical course that show decreased SBME via postoperative MRI, an extended follow-up in a conservative manner could be considered. LEVEL OF EVIDENCE Level III.

Abstract
BACKGROUND Arthroscopic bone marrow stimulation (BMS) is considered the first-line treatment for osteochondral lesions of the talus (OLTs). However, the long-term stability of the clinical success of BMS remains unclear. PURPOSE To investigate the long-term clinical outcomes among patients who underwent BMS for OLT and to identify prognostic factors for the need for revision surgery. STUDY DESIGN Case series; Level of evidence, 4. METHODS A retrospective analysis was performed on 202 ankles (189 patients) that were treated with BMS for OLT and had a minimum follow-up of 10 years. The visual analog scale for pain, American Orthopaedic Foot & Ankle Society ankle-hindfoot score, and the Foot and Ankle Outcome Score (FAOS) were assessed by repeated measures analysis of variance. Prognostic factors associated with revision surgery were evaluated with Cox proportional hazard regression models and log-rank tests. RESULTS The mean lesion size was 105.32 mm2 (range, 19.75-322.79); 42 ankles (20.8%) had large lesions (≥150 mm2). The mean visual analog scale for pain improved from 7.11 ± 1.73 (mean ± SD) preoperatively to 1.44 ± 1.52, 1.46 ± 1.57, and 1.99 ± 1.67 at 1, 3 to 6, and ≥10 years, respectively, after BMS (P < .001). The mean ankle-hindfoot score also improved, from 58.22 ± 13.57 preoperatively to 86.88 ± 10.61, 86.17 ± 10.23, and 82.76 ± 11.65 at 1, 3 to 6, and ≥10 years after BMS (P < .001). The FAOS at the final follow-up was 82.97 ± 13.95 for pain, 81.81 ± 14.64 for symptoms, 83.49 ± 11.04 for activities of daily living, 79.34 ± 11.61 for sports, and 78.71 ± 12.42 for quality of life. Twelve ankles underwent revision surgery after a mean 53.5 months. Significant prognostic factors associated with revision surgery were the size of the lesion (preoperative magnetic resonance imaging measurement ≥150 mm2; P = .014) and obesity (body mass index ≥25; P = .009). CONCLUSION BMS for OLT yields satisfactory clinical outcomes at a mean follow-up of 13.9 years. The success of the surgery may depend on the lesion size and body mass index of the patient.

Abstract
PURPOSE The purpose of this study is to systematically review the literature and to evaluate the reported rehabilitation protocols, return to play guidelines and subsequent rates and timing of return to play following bone marrow stimulation (BMS) for osteochondral lesions of the talus (OLT). METHODS MEDLINE, EMBASE and the Cochrane Library were searched according to the PRISMA guidelines in September 2017. The rate and timing of return to play was assessed. The rehabilitation protocols were recorded, including time to start range of motion, partial weight-bearing and complete weight-bearing. RESULTS Fifty-seven studies with 3072 ankles were included, with a mean age of 36.9 years (range 23-56.8 years), and a mean follow-up of 46.0 months (range 1.5-141 months). The mean rate of return to play was 86.8% (range 60-100%), and the mean time to return to play was 4.5 months (range 3.5-5.9 months). There was large variability in the reported rehabilitation protocols. Range of motion exercises were most often allowed to begin in the first week (46.2%), and second week postoperatively (23.1%). The most commonly reported time to start partial weight-bearing was the first week (38.8%), and the most frequently reported time of commencing full weight-bearing was 6 weeks (28.8%). Surgeons most often allowed return to play at 4 months (37.5%). CONCLUSIONS There is a high rate of return following BMS for OLT with 86.8% and the mean time to return to play was 4.5 months. There is also a significant deficiency in reported rehabilitation protocols, and poor quality reporting in return to play criteria. Early weightbearing and early postoperative range of motion exercises appear to be advantageous in accelerated return to sports. LEVEL OF EVIDENCE Level IV.

Abstract
Background: Lesion size is a major determinant of treatment strategy for osteochondral lesions of the talus (OLTs). Although magnetic resonance imaging (MRI) is commonly used in the preoperative evaluation of OLTs, the reliability of the MRI measurement compared with the arthroscopic measurement is unknown. Purpose: To compare preoperative lesion size measured on MRI versus intraoperative lesion size measured during arthroscopy. Study Design: Cohort study (diagnosis); Level of evidence, 2. Methods: We retrospectively reviewed a consecutive series of patients treated with bone marrow stimulation for OLTs. The diameter of the lesion was measured at its widest point in 2 planes, and MRI measurements were compared with those made during arthroscopy using a custom-made graduated probe. Results: A total of 39 patients with 45 OLTs were analyzed. Mean ± SD area measurements on MRI were significantly greater than the equivalent arthroscopic measurements (42.2 ± 30.5 vs 28.6 ± 23.1 mm2, respectively; P = .03). Compared with the arthroscopic measurement, MRI overestimated OLT size in 53.3% (24/45) of ankles and underestimated OLT size in 24.4% (11/45). The mean MRI diameter measurement was significantly greater than the arthroscopic measurement in the coronal plane (MRI diameter vs arthroscopic measurement coronal plane, 6.1 ± 2.6 vs 4.9 ± 2.3 mm, P = .03; sagittal plane, 8.0 ± 3.6 vs 6.3 ± 3.6 mm, P = .05). Further, MRI overestimated coronal diameter in 48.9% (22/45) of ankles and underestimated in 26.7% (12/45) compared with the arthroscopic measurement. Similarly, sagittal plane MRI diameter measurements overestimated lesion size in 46.7% (21/45) of ankles and underestimated lesion size in 28.9% (13/45) compared with the arthroscopic findings. Conclusion: In a majority of lesions, MRI overestimated OLT area and diameter compared with arthroscopy. Surgeons should be aware of the discrepancies that can exist between MRI and arthroscopic measurements, as these data are important in making treatment decisions and educating patients.

Abstract
BACKGROUND: Arthroscopic microfracture can effectively treat osteochondral lesions of the talus (OLTs). However, very few studies have reported on symptomatic improvement duration and time when symptomatic improvement ceases. This study aimed to investigate the clinical outcome changes after arthroscopic microfracture in patients with OLT. METHODS: Among patients who underwent arthroscopic microfracture for OLT, 70 patients were available for follow-up for more than 3 years. Of these, 6 patients who showed worsening or no improvement in the 6 months after surgery were excluded, and a total of 64 patients were included in the analysis. To analyze and compare the clinical outcome changes according to time, the visual analog scale (VAS) and American Orthopaedic Foot & Ankle Society (AOFAS) ankle-hindfoot scores were evaluated every 3 months up to 1 year postoperatively and every 1 year thereafter. The clinical outcome differences based on the lesion size, lesion location, lesion containment, presence of cyst and bone marrow edema, age, sex, and obesity were analyzed. RESULTS: The preoperative and final follow-up VAS scores significantly improved from 6.2 ± 1.1 to 1.2 ± 1.1 ( P< .05) and the AOFAS score from 63.1 ± 7.3 to 91.0 ± 7.3 ( P< .05). The overall success rate for arthroscopic microfracture in this study was 88.6%. The postoperative VAS and AOFAS scores at 3, 6, 9, 12, 24, and 36 months were 3.7 ± 1.4, 2.5 ± 1.3, 2.0 ± 1.1, 1.6 ± 1.2, 1.2 ± 1.2, and 1.3 ± 1.2 and 74.7 ± 10.3, 80.5 ± 8.9, 84.3 ± 7.4, 88.3 ± 7.3, 91.1 ± 7.2, and 90.8 ± 7.5, respectively, showing significant improvements up to 2 years. After 2 years, the symptoms did not improve but were maintained at a certain level up to 3 years. No clinical outcome differences based on the lesion size, lesion containment, presence of cyst and bone marrow edema, age, sex, and obesity were observed. CONCLUSION: Symptomatic improvement early after arthroscopic microfracture for OLT was observed continuously for up to 2 years postoperatively. Symptom improvement was maintained without worsening for up to 3 years after surgery. Determining the final outcome of microfracture at least after 2 years would be reasonable. LEVEL OF EVIDENCE: Level IV, case series.

Abstract
PURPOSE Little is known about the arthroscopic or radiographic outcomes after arthroscopic microfracture of osteochondral lesions of the talus (OLTs). The purpose of this study was to investigate tissue growth after arthroscopic microfracture of OLTs using computed tomography arthrography (CTA) and to identify the relationship between CTA findings and clinical outcomes. We hypothesized that the morphology of the repaired tissue would be similar to that of normal anatomy and correlate with the clinical outcomes. METHODS Forty-two ankles treated using arthroscopic microfracture of OLTs between 2009 and 2014 were monitored. CTA was performed post-operatively at 6 months and at 1 and 2 years after surgery. The post-operative thickness of the repaired tissue associated with OLT (grade) and the volume of the subchondral cystic lesions were evaluated using CTA. Clinical outcomes, including the pain visual analog scale (VAS) and American Orthopaedic Foot and Ankle Society (AOFAS) ankle functional scores, were evaluated and correlated with CTA. RESULTS The proportion of fully grown tissue (grade 3) increased over time; specifically, the rates were 12/40 (33.3%) at 6 months, 11/18 (61.1%) at 1 year, and 8/10 (80%) at 2 years after surgery (p = 0.005). The VAS pain (p < 0.001) and AOFAS scores (p < 0.001) were also improved at the final follow-up; however, they were not associated with repaired tissue thickness as shown by CTA (n.s.). CONCLUSIONS After microfracture of OLTs, tissue growth in the osteochondral defects was well visualized using CT arthrography and was observed in most cases. However, the CTA findings were not related to the clinical outcomes. LEVEL OF EVIDENCE IV.

Abstract
BACKGROUND The evidence supporting best practice guidelines in the field of cartilage repair of the ankle are based on both low quality and low levels of evidence. Therefore, an international consensus group of experts was convened to collaboratively advance toward consensus opinions based on the best available evidence on key topics within cartilage repair of the ankle. The purpose of this article is to report the consensus statements on Post-treatment Follow-up, Imaging and Outcome Scores developed at the 2017 International Consensus Meeting on Cartilage Repair of the Ankle. METHODS Seventy-five international experts in cartilage repair of the ankle representing 25 countries and 1 territory were convened and participated in a process based on the Delphi method of achieving consensus. Questions and statements were drafted within 11 working groups focusing on specific topics within cartilage repair of the ankle, after which a comprehensive literature review was performed and the available evidence for each statement was graded. Discussion and debate occurred in cases where statements were not agreed on in unanimous fashion within the working groups. A final vote was then held, and the strength of consensus was characterized as follows: consensus, 51% to 74%; strong consensus, 75% to 99%; unanimous, 100%. RESULTS A total of 12 statements on Post-treatment Follow-up, Imaging, and Outcome Scores reached consensus during the 2017 International Consensus Meeting on Cartilage Repair of the Ankle. All 12 statements reached strong consensus (greater than 75% agreement). CONCLUSIONS This international consensus derived from leaders in the field will assist clinicians with post-treatment follow-up, imaging, and outcome scores after management of a cartilage injury of the ankle in the general population. Moreover, healing, rehabilitation, and final outcomes can be optimized for the individual patient.

Abstract
BACKGROUND The literature on the osteochondral lesion of the talus (OLT) in skeletally immature children is scarce and little is known about the clinical outcomes and the radiologic appearance of these lesions after surgical treatment. The aim of this study was to assess mid-term clinical and magnetic resonance imaging (MRI) outcomes after arthroscopic microfracture (AM) of OLT in skeletally immature children. METHODS Thirteen patients with OLT treated by AM before skeletal maturity were included in the study. The Berndt and Harty outcome question, the Single Assessment Numeric Evaluation question, and the Martin questionnaire were used to obtain patients' subjective satisfaction with their operated ankle. Functional outcomes preoperatively and postoperatively were evaluated using the American Orthopaedic Foot and Ankle Society (AOFAS) score. MRI scans were performed postoperatively using a magnetic resonance observation of cartilage repair tissue (MOCART) scoring system for 11 ankles. RESULTS The median age was 15 years (range, 13 to 16 y) and the median follow-up period was 5.6 years (range, 3.8 to 13.6 y). According to the Berndt and Harty outcome question, good clinical results were reported in 10 (76.9%) and fair in 3 (23.1%) patients. The postoperative AOFAS score was significantly improved when compared with the preoperative AOFAS score, with a mean increase of 35 points (P<0.001). The overall MOCART score was 65 (range, 10 to 75). MRI variables of the MOCART scoring system showed no association with clinical outcomes. CONCLUSIONS AM seems to be an effective surgical method for the treatment of OLT in skeletally immature children. LEVEL OF EVIDENCE Level IV-therapeutic studies, case series.

Abstract
PURPOSE The purpose of this systematic literature review is to detect the most effective treatment option for primary talar osteochondral defects in adults. METHODS A literature search was performed to identify studies published from January 1996 to February 2017 using PubMed (MEDLINE), EMBASE, CDSR, DARE, and CENTRAL. Two authors separately and independently screened the search results and conducted the quality assessment using the Newcastle-Ottawa Scale. Subsequently, success rates per separate study were calculated. Studies methodologically eligible for a simplified pooling method were combined. RESULTS Fifty-two studies with 1236 primary talar osteochondral defects were included of which forty-one studies were retrospective and eleven prospective. Two randomised controlled trials (RCTs) were identified. Heterogeneity concerning methodological nature was observed, and there was variety in reported success rates. A simplified pooling method performed for eleven retrospective case series including 317 ankles in the bone marrow stimulation group yielded a success rate of 82% [CI 78-86%]. For seven retrospective case series investigating an osteochondral autograft transfer system or an osteoperiosteal cylinder graft insertion with in total 78 included ankles the pooled success rate was calculated to be 77% [CI 66-85%]. CONCLUSIONS For primary talar osteochondral defects, none of the treatment options showed any superiority over others. LEVEL OF EVIDENCE IV.

Abstract
AIM To clarify the quality of the studies indicating lesion size and/or containment as prognostic indicators of bone marrow stimulation (BMS) for osteochondral lesions of the talus (OLT).
METHODS Two reviewers searched the PubMed/MEDLINE and EMBASE databases using specific terms on March 2015 in accordance with the Preferred Reporting Items for Systemic Reviews and Meta-Analyses guidelines. Predetermined variables were extracted for all the included studies. Level of evidence (LOE) was determined using previously published criteria by the Journal of Bone and Joint Surgery and methodological quality of evidence (MQOE) was evaluated using the Modified Coleman Methodology Score.
RESULTS This review included 22 studies. Overall, 21 of the 22 (95.5%) included studies were level IV or level III evidences. The remaining study was a level II evidence. MQOE analysis revealed 14 of the 22 (63.6%) included studies having fair quality, 7 (31.8%) studies having poor quality and only 1 study having excellent quality.
CONCLUSION The evidence supporting the use of lesion size and containment as prognostic indicators of BMS for OLTs has been shown to be of low quality.

Abstract
Osteochondral lesion of the talus (OLT) is a common condition associated with ankle injury that brings challenges in the diagnosis and treatment. Symptoms related to this condition are nonspecific including pain, swelling, stiffness, and mechanical symptoms of locking and catching. While the natural history of the OLTs is not well understood, surgical treatment is often required especially in chronic cases and acute cases with displaced articular fragments. Arthroscopic treatment of the OLTs aims to restore ankle joint function and pain relief by the removal of the chondral or osteochondral fragment, debridement and stabilization of cartilage rim and subchondral bone, and stimulate healing of the bone and damaged cartilage. In patients with a large lesion or after a failure of previous bone marrow stimulation, biologic restoration techniques including the use of particulate juvenile cartilage techniques, autogenous chondrocyte implantation, and osteochondral autograft or allograft transplantation may have role. This article summarizes the contemporary concepts in the clinical evaluation and treatment of OLTs with particular emphasis on surgical strategies.

Abstract
Introduction An increasing number of young patients are diagnosed with chondral lesions. Minimally invasive surgical techniques are important in order to delay progression of the early stages of osteoarthritis and the need for total joint replacement. Materials and methods Patients (n = 32) who had received microfracturing of the shoulder were retrospectively enrolled, of whom 5 had received shoulder replacements after a mean time of 47 months. Of these patients, 23 completed the Disabilities of the Arm, Shoulder and Hand (DASH) and Constant–Murley Scores in addition to an additional subjective questionnaire. Patients were then clinically examined and received x‑ray analysis of the operated shoulder. Data from an additional 4 patients were acquired by telephone interview. Results Mean follow-up was 105 months. Of the included patients, 13/27 patients reported no pain, 12/27 patients moderate pain. Of these 12, 6/27 reported pain only at night and 3/27 only during rest. Concerning the outcome of surgery, 19/27 patients were “satisfied” or “very satisfied”. There was a statistically significant increase in internal rotation, but no further differences in the range of motion pre- and postoperatively. Patients without any signs of osteoarthritis before surgery showed statistically significantly better outcomes. There was a statistically significant increase in radiological signs of osteoarthrosis in pre- versus postoperative patients. Patients with bipolar lesions showed statistically significantly poorer Subjective Shoulder Value (SSV) results. Conclusion Even though microfracturing does not prevent radiographic progression, microfracture of the glenohumeral joint might be worth considering as part of a treatment regimen for younger patients who may not yet be treated with arthroplasty.

Abstract
BACKGROUND The critical lesion size treated with bone marrow stimulation (BMS) for osteochondral lesions of the talus (OLTs) has been 150 mm2 in area or 15 mm in diameter. However, recent investigations have failed to detect a significant correlation between the lesion size and clinical outcomes after BMS for OLTs. PURPOSE To systematically review clinical studies reporting both the lesion size and clinical outcomes after BMS for OLTs. STUDY DESIGN Systematic review. METHODS A systematic search of the MEDLINE and EMBASE databases was performed in March 2015 based on the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Included studies were evaluated with regard to the level of evidence (LOE), quality of evidence (QOE), lesion size, and clinical outcomes. RESULTS Twenty-five studies with 1868 ankles were included; 88% were either LOE 3 or 4, and 96% did not have good QOE. The mean area was 103.8 ± 10.2 mm2 in 20 studies, and the mean diameter was 10.0 ± 3.2 mm in 5 studies. The mean American Orthopaedic Foot and Ankle Society score improved from 62.4 ± 7.9 preoperatively to 83.9 ± 9.2 at a mean 54.1-month follow-up in 14 studies reporting both preoperative and postoperative scores with a mean follow-up of more than 2 years. A significant correlation was found in 3 studies, with a mean lesion area of 107.4 ± 10.4 mm2, while none was reported in 8 studies, with a mean lesion area of 85.3 ± 9.2 mm2. The lesion diameter significantly correlated with clinical outcomes in 2 studies (mean diameter, 10.2 ± 3.2 mm), whereas none was found in 2 studies (mean diameter, 8.8 ± 0.0 mm). However, the reported lesion size measurement method and evaluation method of clinical outcomes widely varied among the studies. CONCLUSION An assessment of the currently available data does suggest that BMS may best be reserved for OLT sizes less than 107.4 mm2 in area and/or 10.2 mm in diameter. Future development in legitimate prognostic size guidelines based on high-quality evidence that correlate with outcomes will surely provide patients with the best potential for successful long-term outcomes.

Abstract
BACKGROUND The purpose of the study was to assess the functional and radiologic outcomes after AT-AMIC (arthroscopic talus autologous matrix-induced chondrogenesis) in 2 weight groups of patients with osteochondral lesions of the talus (OLTs): patients with BMI <25 (Healthy Weight Group [HG]) and with BMI ≥25 (Overweight Group [OG]). METHODS Thirty-seven patients were evaluated. HG was composed of 21 patients (BMI = 21.90 ± 1.94), whereas OG consisted of 16 patients (BMI = 27.41 ± 1.98). All patients were treated with AT-AMIC repair for OLTs. Magnetic resonance imaging (MRI), computed tomography (CT), Visual Analgoue Scale (VAS) for pain, American Orthopaedic Foot & Ankle Society (AOFAS) Ankle and Hindfoot score and Short-Form Health Survey (SF-12) were administered preoperatively (T0) and at 6 (T1), 12 (T2), and 24 (T3) months postoperatively. RESULTS In both groups, we found a significant difference for clinical and radiologic parameters with analysis of variance for repeated measures through 4 time points ( P < .001). In HG, AOFAS increased at every follow-up ( P < .05), whereas in OG, AOFAS improved only between T2 and T3 ( P = .0104). In OG we found a significant difference comparing CT and MRI at each follow-up; in HG this difference was found only at T0 ( P < .0001) and T1 ( P = .0492). Finally, OG presented a significantly larger lesion measured with MRI at T0 ( P = .033). CONCLUSIONS OLTs in overweight patients were characterized by a larger preoperative size. At final follow-up, both groups showed a significant clinical improvement. AT-AMIC can be considered a safe and reliable procedure, regardless of weight, with a significant improvement also in quality of life. LEVEL OF EVIDENCE Level III, comparative study.

Abstract
Osteochondral lesions of the talus are common injuries that affect a wide variety of active patients. The majority of these lesions are associated with ankle sprains and fractures though several nontraumatic etiologies have also been recognized. Patients normally present with a history of prior ankle injury and/or instability. In addition to standard ankle radiographs, magnetic resonance imaging and computed tomography are used to characterize the extent of the lesion and involvement of the subchondral bone. Symptomatic nondisplaced lesions can often be treated conservatively within the pediatric population though this treatment is less successful in adults. Bone marrow stimulation techniques such as microfracture have yielded favorable results for the treatment of small (<15 mm) lesions. Osteochondral autograft can be harvested most commonly from the ipsilateral knee and carries the benefit of repairing defects with native hyaline cartilage. Osteochondral allograft transplant is reserved for large cystic lesions that lack subchondral bone integrity. Cell-based repair techniques such as autologous chondrocyte implantation and matrix-associated chondrocyte implantation have been increasingly used in an attempt to repair the lesion with hyaline cartilage though these techniques require adequate subchondral bone. Biological agents such as platelet-rich plasma and bone marrow aspirate have been more recently studied as an adjunct to operative treatment but their use remains theoretical. The present article reviews the current concepts in the evaluation and management of osteochondral lesions of the talus, with a focus on the available surgical treatment options.

Abstract
OBJECTIVE There remains no consensus on a postoperative protocol following arthroscopic treatment of osteochondral lesions of the talus (OLTs) and most studies report a period of immobilization and nonweightbearing. Outcomes are believed to decrease with larger size. The purpose of our study was to evaluate patients who underwent arthroscopic treatment of large (≥150 mm2) OLTs with immediate unrestricted weightbearing and mobilization postoperatively. DESIGN Patients who underwent arthroscopic bone marrow stimulation for osteochondral defects were identified. Exclusion criteria included lesions less than 150 mm2, additional procedures other than ligament reconstruction, incongruent ankle joint, arthritis, and tibial plafond lesions. Postoperatively, all patients were placed into a soft dressing and were allowed immediate weightbearing as tolerated. Patients were considered failures if their AOFAS (American Orthopaedic Foot and Ankle Society) score was less than 80 or if they underwent osteochondral transplant. RESULTS Thirteen patients were available for follow-up. Two patients underwent osteochondral transplant and were considered failures. Of the remaining 11, the average follow-up time after surgery was 33 months (range, 7-59 months). Average age was 37 years (range, 15-56 years), and lesion size averaged 239 mm2 (range, 150-400 mm2). Average postoperative scores included foot function index 50 (range, 23-136), visual analog scale 3 (range, 0-8), and AOFAS hindfoot 82 (range, 40-100). The group's overall success rate was 54% (7/13). CONCLUSION The results of our study are higher than those previously published studies on large lesions with a more restricted postoperative rehabilitation, suggesting that unrestricted weightbearing and range of motion does not diminish patient outcomes.

Abstract
PURPOSE The purpose of this study was to compare the clinical and magnetic resonance imaging (MRI) outcomes of arthroscopic microfracture surgery alone or in combination with hyaluronic acid (HA) injection in the treatment of osteochondral lesions of the talus. METHODS Thirty-five patients with osteochondral lesions of the talus who underwent arthroscopic microfracture were included and followed up for at least 9 months post-operatively. The patients were randomly divided into non-injection group (n = 17) who received treatment with microfracture surgery alone and injection group (n = 18) who also accepted intra-articular injection of HA post-operatively. Quantitative MRI was used to evaluate the cartilage repair after surgery. American Orthopaedic Foot and Ankle Society (AOFAS) Ankle-Hind foot Scale scores and Visual Analogue Scale (VAS) scores were used to evaluate clinical outcomes. RESULTS After operation, the MRI outcomes showed that the thickness index was higher (0.8 ± 0.1 vs. 0.7 ± 0.1) and the T2 index was lower (1.2 ± 0.1 vs. 1.4 ± 0.1) in the injection group than in the non-injection group (P < 0.01). As for the volumes of subchondral bone marrow oedema, there are no significant differences between groups (n.s.). Compared with the non-injection group, the AOFAS score and the VAS score yielded a higher level of improvement in injection group at final follow-up post-operatively (P < 0.05). CONCLUSIONS Arthroscopic microfracture is a safe and effective procedure for osteochondral lesions of the talus. Intra-articular HA injection as an adjunct to arthroscopic microfracture might offer better functional recovery than microfracture alone. LEVEL OF EVIDENCE II.

Abstract
PURPOSE To examine the level of evidence and methodologic quality of studies reporting surgical treatments for osteochondral lesions of the ankle. METHODS A search was performed using the PubMed/Medline, Embase, CINAHL (Cumulative Index to Nursing and Allied Health Literature), and Cochrane databases for all studies in which the primary objective was to report the outcome after surgical treatment of osteochondral lesions of the ankle. Studies reporting outcomes of microfracture, bone marrow stimulation, autologous osteochondral transplantation, osteochondral allograft transplantation, and autologous chondrocyte implantation were the focus of this analysis because they are most commonly reported in the literature. Two independent investigators scored each study from 0 to 100 based on 10 criteria from the modified Coleman Methodology Score (CMS) and assigned a level of evidence using the criteria established by the Journal of Bone and Joint Surgery. Data were collected on the study type, year of publication, number of surgical procedures, mean follow-up, preoperative and postoperative American Orthopaedic Foot & Ankle Society score, measures used to assess outcome, geography, institution type, and conflict of interest. RESULTS Eighty-three studies reporting the results of 2,382 patients who underwent 2,425 surgical procedures for osteochondral lesions of the ankle met the inclusion criteria. Ninety percent of studies were of Level IV evidence. The mean CMS for all scored studies was 53.6 of 100, and 5 areas were identified as methodologically weak: study size, type of study, description of postoperative rehabilitation, procedure for assessing outcome, and description of the selection process. There was no significant difference between the CMS and the type of surgical technique (P = .1411). A statistically significant patient-weighted correlation was found between the CMS and the level of evidence (r = -0.28, P = .0072). There was no statistically significant patient-weighted correlation found between the CMS and the institution type (r = 0.05, P = .6480) or financial conflict of interest (r = -0.16, P = .1256). CONCLUSIONS Most studies assessing the clinical outcomes of cartilage repair of the ankle are of a low level of evidence and of poor methodologic quality. LEVEL OF EVIDENCE Level IV, systematic review of Level I through IV studies.

Abstract
OBJECTIVES The goal of cartilage repair techniques such as microfracture (MFX) or matrix-associated autologous chondrocyte transplantation (MACT) is to produce repair tissue (RT) with sufficient glycosaminoglycan (GAG) content. Sodium magnetic resonance imaging (MRI) offers a direct and noninvasive evaluation of the GAG content in native cartilage and RT. In the femoral cartilage, this method was able to distinguish between RTs produced by MFX and MACT having different GAG contents. However, it needs to be clarified whether sodium MRI can be useful for evaluating RT in thin ankle cartilage. Thus, the aims of this 7-T study were (1) to validate our sodium MRI protocol in cadaver ankle samples, (2) to evaluate the sodium corrected signal intensities (cSI) in cartilage of volunteers, (3) and to compare sodium values in RT between patients after MFX and MACT treatment. MATERIALS AND METHODS Five human cadaver ankle samples as well as ankles of 9 asymptomatic volunteers, 6 MFX patients and 6 MACT patients were measured in this 7-T study. Sodium values from the ankle samples were compared with histochemically evaluated GAG content. In the volunteers, sodium cSI values were calculated in the cartilages of ankle and subtalar joint. In the patients, sodium cSI in RT and reference cartilage were measured, morphological appearance of RT was evaluated using the magnetic resonance observation of cartilage repair tissue (MOCART) scoring system, and clinical outcome before and after surgery was assessed using the American Orthopaedic Foot and Ankle Society score and Modified Cincinnati Knee Scale. All regions of interest were defined on morphological images and subsequently transferred to the corresponding sodium images. Analysis of variance, t tests, and Pearson correlation coefficients were evaluated. RESULTS In the patients, significantly lower sodium cSI values were found in RT than in reference cartilage for the MFX (P = 0.007) and MACT patients (P = 0.008). Sodium cSI and MOCART scores in RT did not differ between the MFX and MACT patients (P = 0.185). No significant difference in sodium cSI was found between reference cartilage of the volunteers and the patients (P = 0.355). The patients showed significantly higher American Orthopaedic Foot and Ankle Society and Modified Cincinnati scores after treatment than they did before treatment. In the volunteers, sodium cSI was significantly higher in the tibial cartilage than in the talar cartilage of ankle joint (P = 0.002) and in the talar cartilage than in the calcaneal cartilage of subtalar joint (P < 0.001). Data from the cadaver ankle samples showed a strong linear relationship between the sodium values and the histochemically determined GAG content (r = 0.800; P < 0.001; R = 0.639). CONCLUSIONS This study demonstrates the feasibility of in vivo quantification of sodium cSI, which can be used for GAG content evaluation in thin cartilages of ankle and subtalar joints at 7 T. A strong correlation observed between the histochemically evaluated GAG content and the sodium values proved the sufficient sensitivity of sodium MRI to changes in the GAG content of cartilages in the ankle. Both MFX and MACT produced RT with lower sodium cSI and, thus, of lower quality compared with reference cartilage in the patients or in the volunteers. Our results suggest that MFX and MACT produce RT with similar GAG content and similar morphological appearance in patients with similar surgery outcome. Sodium MRI at 7 T allows a quantitative evaluation of RT quality in the ankle and may thus be useful in the noninvasive assessment of new cartilage repair procedures.

Abstract
OBJECTIVES To quantitatively evaluate cartilage repair after microfracture (MF) for ankle osteochondritis dissecans (OCD) using MRI and analyse correlations between MRI and clinical outcome. METHODS Forty-eight patients were recruited and underwent MR imaging, including 3D-DESS, T2-mapping and T2-STIR sequences, and completed American Orthopaedic Foot and Ankle Society (AOFAS) scoring. Thickness index, T2 index of repair tissue (RT) and volume of subchondral bone marrow oedema (BME) were calculated. Subjects were divided into two groups: group A (3-12 months post-op), and group B (12-24 months post-op). Student's t test was used to compare the MRI and AOFAS score between two groups and Pearson's correlation coefficient to analyse correlations between them. RESULTS Thickness index and AOFAS score of group B were higher than group A (P < 0.001, P < 0.001). T2 index and BME of group B were lower than group A (P < 0.001, P = 0.012). Thickness index, T2 index and BME were all correlated with AOFAS score (r = 0.416, r = -0.475, r = -0.353), but BME was correlated with neither thickness index nor T2 index. CONCLUSIONS Significant improvement from MF can be expected on the basis of the outcomes of quantitative MRI and AOFAS score. MRI was correlated with AOFAS score. BME is insufficient as an independent predictor to evaluate repair quality, but reduction of BME can improve the patient's clinical outcome. KEY POINTS • Patients with unstable ankle OCD had satisfactory clinical outcome after MF. • Quantitative MRI correlates with clinical outcome after MF for ankle OCD. • The reduction of subchondral BME will improve the patient's clinical outcome. • Quantitative MRI can monitor the process of cartilage repair over time.

Abstract
BACKGROUND The defect size of an osteochondral lesion of the talus is one of the most important prognostic factors for deciding clinical outcomes. However, the prognostic factors for small osteochondral lesions of the talus are unknown. PURPOSE To investigate the significant prognostic factors for small osteochondral lesions of the talus using arthroscopic bone marrow stimulation techniques. STUDY DESIGN Case series; Level of evidence, 4. METHODS Fifty ankles in 50 patients treated with arthroscopic bone marrow stimulation techniques for an osteochondral lesion of the talus (<150 mm(2)) were evaluated for prognostic factors. The patients were 22 men and 28 women (mean age, 35.0 years). Outcomes were measured using the American Orthopaedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot Scale, Berndt and Harty scale, and Saxena criteria. RESULTS The mean lesion size was 62 mm(2) (range, 7-119 mm(2)). The mean AOFAS score improved from 74 (range, 18-90) preoperatively to 90 (range, 67-100) postoperatively. The Saxena criteria results were excellent, good, fair, and poor in 36 (72%), 8 (16%), 5 (10%), and 1 (2%) patients, respectively. The Berndt and Harty scale results were good in 34 (68%), fair in 6 (12%), and poor in 10 (20%) patients. Linear regression analyses showed prognostic significance for lesion depth and outcome. Medial lesions had a significantly higher incidence of poor outcomes than lateral lesions (P < .05). Among the medial lesions, lesions uncovered with the medial malleolus had inferior outcomes compared with covered lesions (P < .0001). There was no association between clinical outcome and lesion size or body mass index. In older patients (≥40 years), there was a significant trend toward inferior clinical outcomes (P < .05). CONCLUSION Arthroscopic bone marrow stimulation techniques provided satisfactory clinical outcomes. However, older patients, deep lesions, and medial lesions uncovered with the medial malleolus were associated with inferior clinical outcomes.
