Abstract
The gold standard diagnostic imaging tool for ankle OCLs is magnetic resonance imaging, which allows precise evaluation of the articular cartilage and assessment of the surrounding soft tissue structures. Post-operative morphologic MRI assessment via MOCART scores provide semi-quantitative analysis of the repair tissue, but mixed evidence exists regarding its association with post-operative outcomes. Post-operative biochemical MRIs allow assessment of the collagen network of the articular cartilage via T2-mapping and T2∗ mapping, and assessment of the articular glycosaminoglycan content via delayed gadolinium-enhanced MRI of cartilage (dGEMRIC), T1rho mapping and sodium imaging.

Abstract
Lateral ankle ligament complex injuries are most commonly managed nonoperatively. If no improvements have been made following conservative management, surgical intervention is warranted. Concerns have been raised regarding complication rates following open and traditional arthroscopic anatomical repair. In-office needle arthroscopic anterior talo-fibular ligament repair provides a minimally invasive arthroscopic approach to the diagnosis and treatment of chronic lateral ankle instability. The limited soft tissue trauma facilitates rapid return to daily and sporting activities making this an attractive alternative approach to lateral ankle ligament complex injuries.

Abstract
In-office needle arthroscopy (IONA) has been a readily available tool dating back to the 1990s, primarily for diagnostic purposes. This technique was not fully accepted and implemented because of significant limitations with the image quality and lack of instrumentation available to simultaneously treat the identified pathologies. However, recent advancements in IONA technology have made it possible to perform arthroscopic procedures under local anesthesia in the office setting, which once required a full operating suite. IONA has revolutionized how we treat foot and ankle pathologies in our practice. IONA allows the patient to be an active participant in the procedure and provides an interactive experience. IONA can be used to treat a range of foot and ankle pathologies, including anterior ankle impingement, posterior ankle impingement, osteochondral lesions of the ankle joint, hallux rigidus, lateral ankle ligament repair, and tendoscopic treatment of Achilles, peroneal, and posterior tibial tendon disorders. Excellent outcomes with regard to subjective clinical outcomes, return to play times, and complications have been reported following IONA for these pathologies.

Abstract
PURPOSE To systematically review and evaluate the current meta-analyses for the treatment of acute Achilles tendon rupture (AATR). This study can provide clinicians with a clear overview of the current literature to aid clinical decision-making and the optimal formulation of treatment plans for AATR. METHODS Two independent reviewers searched PubMed and Embase on June 2, 2022 based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Assessment of evidence was twofold: level of evidence (LoE) and quality of evidence (QoE). LoE was evaluated using published criteria by The Journal of Bone and Joint Surgery and the QoE by the Assessing the Methodological Quality of Systematic Reviews (AMSTAR) scale. Pooled complication rates were highlighted for significance in favour of one treatment arm or no significance. RESULTS There were 34 meta-analyses that met the eligibility criteria, with 28 studies of LoE 1, and the mean QoE was 9.8 ± 1.2. Significantly lower re-rupture rates were reported with surgical (2.3-5%) versus conservative treatment (3.9-13%), but conservative treatment was favoured in terms of lower complication rates. The re-rupture rates were not significantly different between percutaneous repair or minimally invasive surgery (MIS) compared to open repair, but MIS was favoured in terms of lower complication rates (7.5-10.4%). When comparing rehabilitation protocols following open repair (four studies), conservative treatment (nine studies), or combined (three studies), there was no significant difference in terms of re-rupture or obvious advantage in terms of lower complication rates between early versus later rehabilitation. CONCLUSION This systematic review found that surgical treatment was significantly favoured over conservative treatment for re-rupture, but conservative treatment had lower complication rates other than re-rupture, notably for infections and sural nerve injury. Open repair had similar re-rupture rates to MIS, but lower complication rates; however, the rate of sural nerve injuries was lower in open repair. When comparing earlier versus later rehabilitation, there was no difference in re-rupture rates or obvious advantage in complications between open repair, conservative treatment, or when combined. The findings of this study will allow clinicians to effectively counsel their patients on the postoperative outcomes and complications associated with different treatment approaches for AATR.

Abstract
Osteochondral lesions of the ankle joint are typically associated with a traumatic etiology and present with ankle pain and swelling. Conservative management yields unsatisfactory results because of the poor healing capacity of the articular cartilage. Smaller lesions (<100 mm2 or <10 mm) can be treated with less invasive procedures such as arthroscopic debridement, anterograde drilling, scaffold-based therapies, and augmentation with biological adjuvants. For patients with large lesions (>100 mm2 or >10 mm), cystic lesions, uncontained lesions, or patients who have failed prior bone marrow stimulation, management with autologous osteochondral transplantation is indicated.

Abstract
PURPOSE Acute Achilles tendon ruptures (AATRs) are a common sporting injury, whether for recreational athletes or elite athletes. Prior research has shown returning to physical activity after extended periods of inactivity leads to increased rates of musculoskeletal injuries. The purpose of this study was to investigate rates of acute Achilles' tendon ruptures at a single academic institute in the peri-COVID era, with corollary to the recent NFL season. METHODS A retrospective search was conducted using current procedural terminology to identify the total number of Achilles acute primary repair surgeries performed from years 2017 to 2021. Non-operatively managed AATRs were identified from the same electronic medical record using ICD-10 codes. NFL data were obtained from publicly available sites according to previously validated studies. RESULTS A total of 588 patients who sustained AATRs and underwent primary surgical repair were identified, primarily men (75.7%, n = 445), with an average age of 43.22 ± 14.4 years. The number and corresponding incidence of AATR repairs per year was: 2017: n = 124 (21.1%), 2018: n = 110 (18.7%), 2019: n = 130 (22.1%), 2020: n = 86 (14.6%), 2021: n = 138 (23.5%), indicating a 7.5% decrease in rate of AATRs from 2019 to 2020, followed by an 8.9% increase in incidence from 2020 to 2021. Within the NFL, the number of AATRs resulting in an injured reserve stint increased every regular season from 2019 to 2020: n = 11 (21.2%), to 2020-2021: n = 17 (32.7%), to this past 2021-2022 season: n = 24 (46.2%). CONCLUSION AATR surgeries seem to have increased in 2021 following a 2020 COVID pandemic-induced quarantine for recreational athletes at a single academic institution and for professional athletes in the NFL, although these results are of questionable clinical significance. This provides prognostic information when counseling patients and athletes on return to activity or sport. LEVEL OF EVIDENCE Level IV.

We present a case of calcaneal reconstruction after both an improvised explosive device injury and subsequent salvage procedures left the patient with a large calcaneal defect and damaged hindfoot soft tissue. A subtalar arthrodesis was performed with a femoral head allograft, where it was fused to the remaining calcaneus and superiorly through the talus, to successfully reconstruct this defect. Demineralized bone matrix, bone morphogenetic protein, and concentrated bone marrow aspirate were also added as adjuncts to promote bone remodeling. At final follow-up, the patient denied pain, was fully weight-bearing, and had resumed an active lifestyle. Level of Evidence: Level V, Case Report.

Abstract
BACKGROUND Tarsal tunnel syndrome (TTS) is typically caused by an anatomical variant or mechanical compression of the tibial nerve (TN) with variable success after surgical treatment. METHOD 40 lower-leg specimens were obtained. Dissections were appropriately conducted. Extremities were prepared under formaldehyde solution. The tibial nerve and branches were dissected for measurements and various characteristics. RESULTS The flexor retinaculum had a denser consistency in 22.5% of the cases and the average length was 51.9 mm. The flexor retinaculum as an independent structure was absent and 77.2% of cases as an undistinguished extension of the crural fascia. The lateral plantar nerve (LPN) and abductor digiti minimi (ADM) nerve shared same origin in 80% of cases, 34.5% bifurcated proximal to the DM (Dellon-McKinnon malleolar-calcaneal line) line 31.2% distally and 34.3% at the same level. CONCLUSION Understanding the tibial nerve anatomy will allow us to adapt our surgical technique to improve the treatment of this recurrent pathology.

Abstract
Background: There is minimal literature on the use of suture tape augmentation in the
treatment of chronic lateral ankle instability (CLAI), prompting an
investigation on its use and effect during surgery of the lateral ankle. Purpose: To evaluate the evidence for the use of suture tape augmentation in the
treatment of CLAI and the outcomes after this procedure. Study Design: Systematic review; Level of evidence, 4. Methods: A literature search was performed using the PRISMA (Preferred Reporting Items
for Systematic Reviews and Meta-Analyses) guidelines. Studies were included
if they evaluated the use of suture tape for CLAI. Outcome measures included
the Foot and Ankle Ability Measure, American Orthopaedic Foot and Ankle
Society (AOFAS) score, return to play, and radiological improvement in
anterior talar translation and talar tilt angle. Quantitative and
qualitative analyses were performed. Results: There were 11 studies (2 with level 2 evidence, 1 with level 3, and 8 with
level 4) including 334 patients (334 ankles) that underwent suture-tape
augmentation. The mean age was 27.3 years, 67.3% were women, and the mean
follow-up was 27.6 months (range, 11.5-38.5 months). The mean weighted
postoperative AOFAS score was 95, and 87.7% were able to return to sports.
Overall, 9 recurrent instability events (4.1%) were reported. In 3 studies
that compared Broström repair and suture tape augmentation, there were no
significant differences between the procedures in recurrent instability
(mean difference [MD], 0.81 [95% CI, 0.19 to 3.50]; I2 = 0%; P = .78), Foot and Ankle Ability Measure
(MD, 1.24 [95% CI, –3.73 to 6.21]; I2 = 66%; P = .63), talar tilt angle improvement
(MD, –0.07 [95% CI, –0.68 to 0.54]; I2 = 0%; P = .42), or anterior talar translation
improvement (MD, –0.06 [95% CI, –0.69 to 0.56]; I2 = 0%; P = .77). Conclusion: Suture tape augmentation did not significantly improve clinical or
radiological outcomes in the setting of modified Broström repair for CLAI.
There is currently insufficient evidence to recommend suture tape
augmentation for all patients at this time.

Abstract
Concentrated bone marrow aspirate (CBMA) offers an alternative to sesamoid resection in end stage sesamoid pathology. CBMA potentiates the anti-inflammatory effect, stimulates local tissue regeneration and osteogenesis, when injected into bone. The purpose of this study is to evaluate the functional outcomes in a cohort of athletes following CBMA injection for the treatment of hallux sesamoid disorders. A retrospective case series of consecutive patients treated with CBMA injection for hallux sesamoid disorders were identified. Radiographs, Foot and Ankle Outcome Scores (FAOS), and Visual Analogue Scale (VAS) score were collected pre- and postinjections. Descriptive statistics were presented as the mean and standard deviation for continuous variables and frequency as percentages for categorical variables. Fifteen consecutive patients with were included with a mean follow-up time of 20.1 (range 12-34) months. Significant improvement in all scoring subscales of the FAOS and VAS score was noted preinjection compared to final follow-up postinjection (p < .001). Eight of 11 patients that were involved in sports prior to the CBMA injection returned to play, with 7 successfully returning to preinjury level status. Three patients required further treatment (20%). The case series suggests that CBMA injection is a safe and effective treatment option for hallux sesamoid disorders with a high rate of return to play.

Abstract
Hallux rigidus is the most common arthritic condition of the foot. Interpositional arthroplasty (IPA) is indicated for advanced-stage hallux rigidus and attempts to maintain joint motion through insertion of a biologic spacer into the joint. However, the data evaluating the effectiveness of IPA are limited. The purpose of this study was to systematically review the outcomes of IPA in the treatment of hallux rigidus. MEDLINE, EMBASE, and Cochrane Library databases were systematically reviewed based on the preferred reporting items for systematic reviews and meta-analyses guidelines. Outcomes collected and analyzed included: American Orthopaedic Foot and Ankle Society (AOFAS) hallux metatarsophalangeal-interphalangeal (HMI) score, visual analogue scale score, short-form 36 score, range of motion (ROM), radiographic parameters, and postoperative complications. The level and quality of clinical evidence were recorded and assessed. Sixteen studies with a total of 428 patients met inclusion/exclusion criteria. The mean AOFAS-HMI score improved from 51.6 ± 10.1 (range 35.0-64.2) preoperatively to 86.0 ± 7.7 (range 71.6-95.4) postoperatively (p ≤ .001) at weighted mean follow-up of 58.0 ± 34.5 (range 16.5-135.6) months. The preoperative weighted mean total ROM was 39.3° ± 9.6° (range 24.2-49.9) and the postoperative weighted mean total ROM was 61.5° ± 4.8° (range 54.0-66.5) (p ≤ .001). The complication rate was 21.5% with metatarsalgia as the most commonly reported complication. One study was level 3 and 15 studies were level 4 clinical evidence. This systematic review demonstrates improvement in functional and ROM outcomes following IPA procedure at mid-term follow-up. The procedure however has a moderate complication rate. In addition, there is a low level and quality of evidence in the current literature with inconsistent reporting of data.

Abstract
PURPOSE To evaluate the clinical outcomes of in-office needle arthroscopy (IONA) for the treatment of anterior ankle impingement in the office setting and also evaluate patient experience of the IONA procedure. METHODS A prospectively collected database of 31 patients undergoing IONA for the treatment of anterior ankle impingement between January 2019 and January 2021 was retrospectively reviewed. Inclusion criteria for this study were patients ≥18 years of age, clinical history, physical examination, radiographic imaging, and magnetic resonance imaging findings consistent with anterior ankle impingement for which each patient underwent IONA and had a minimum of 12-month follow-up. Clinical outcomes were evaluated using the following methods preoperatively and at final follow-up: the Foot and Ankle Outcome Scores (FAOS) and Patient-Reported Outcomes Measurement Information System (PROMIS) Pain Interference and Pain Intensity domains. A 5-point Likert scale regarding patient satisfaction with their IONA procedure was evaluated at final follow-up. Wilcoxon signed-rank test was performed to compare preoperative and postoperative outcome scores. RESULTS In total, 31 patients were included in this study, including 18 male and 13 female, with a mean age of 41.7 ± 15.5 years (range, 17-69 years) and mean body mass index of 27.3 ± 5.7 (range, 19.37-41.5). The mean follow-up time was 15.5 ± 4.9 months. The mean postoperative FAOS-reported symptoms, pain, daily activities, sports activities, and quality of life were 79.4 ± 11.9, 82.9 ± 15.3, 83.5 ± 15.4, 71.9 ± 18.5 and 64.3 ± 21.4 at final follow-up respectively. Minimal clinically important difference was achieved by 84% of patients for FAOS pain, 77% for FAOS symptoms, 75% for FAOS Quality of Life, 74% for FAOS sports, 65% for PROMIS Pain Interference, 61% for FAOS Activities of Daily Living, and 42% for PROMIS Pain Intensity. Lastly, 29 patients (94 %) expressed willingness to undergo the same procedure again. CONCLUSIONS The current study demonstrates that IONA treatment of anterior ankle impingement results in significant pain reduction, a low complication rate and excellent patient reported outcomes with high rates of return to work/sport. Additionally, IONA for anterior ankle impingement leads to high patient satisfaction with a significant willingness to undergo the same procedure again. LEVEL OF EVIDENCE IV, Case series study.

Abstract
Purpose To investigate the short-term clinical outcomes and satisfaction for the first set of patients at our institution receiving in-office needle arthroscopy (IONA) for the treatment of posterior ankle impingement syndrome (PAIS). Methods A retrospective cohort study was conducted to evaluate patients who underwent IONA for PAIS between January 2019 and January 2021. Clinical outcomes were evaluated using the Foot and Ankle Outcome Score (FAOS) and Patient-Reported Outcomes Measurement Information System Pain Interference, and Pain Intensity scores. Patient satisfaction was measured at the final follow-up visit with a 5-point Likert scale. The Wilcoxon signed-rank test was performed to compare preoperative and postoperative outcome scores. Results Ten patients (4 male and 6 female) with a mean age of 41.9 ± 15.5 years (range, 24-66 years) were included in the study. The mean follow-up time was 13.3 ± 2.9 months (range, 11-17 months). All mean preoperative FAOS scores demonstrated improvement after IONA, including FAOS symptoms (71.48 ± 10.3 to 80.3 ± 12.6), pain (69.3 ± 11.0 to 78.2 ± 13.9), activities of daily living (61.7 ± 8.8 to 77.93 ± 11.4), sports activities (55.6 ± 12.7 to 76.0 ± 13.6), and quality of life (46.6 ± 9.2 to 71.1 ± 12.1). There were 7 patients who participated in sports activities before the IONA procedure. Within this group, all patients returned to play at a median time of 4.1 weeks (range, 1-14 weeks). The median time to return to work was 3.4 ± 5.3 days. Patients reported an overall positive IONA experience with a mean rating scale of 9.5 ± 1.5 (range, 5-10). Conclusions The current study demonstrates that IONA treatment of PAIS results in significant pain reduction, a low complication rate, and excellent patient-reported outcomes. In addition, IONA for PAIS leads to high patient satisfaction with a significant willingness to undergo the same procedure again. Level of Evidence IV, therapeutic case series.

Abstract
The anterior talofibular ligament (ATFL) is the most frequently injured lateral ligament of the ankle, and up to 20% of patients with ankle sprains may require surgical intervention to correct chronic lateral ankle instability. There has been increased interest in arthroscopic lateral ankle ligament repair techniques to minimize postoperative pain and expedite recovery. Additionally, the use of suture-tape augmentation may allow for improved recovery in those with ATFL reconstruction. The goal of this Technical Note is to describe the steps to performing in-office needle arthroscopy using suture tape as an internal brace for an ATFL deficient ankle. We also include an accompanying discussion on indications and opportunities afforded by an in-office procedure over the traditional operating room suite.

Abstract
In-office needle tendoscopy (IONT) can be used for the diagnosis and treatment of several peroneal tendon pathologies including peroneal tendon tendinopathy, tears, and instability. Benefits of IONT for peroneal tendon disorders include the ability to dynamically evaluate peroneal tendon stability, quicker patient recovery, reduced cost, and improved patient satisfaction. Several studies have suggested that tendoscopic treatment may avoid several complications related to open treatment of peroneal tendon pathologies, including scar formation and groove stenosis. The purpose of the present report is to describe the technique for performing IONT for common peroneal tendon pathologies. This Technical Note describes the techniques for obtaining adequate anesthesia and performing IONT, indications, and advantages of performing these procedures in the office rather than in the operating room.

Abstract
Tendoscopy has been recognized to be a useful technique in the diagnosis and treatment of early tibialis posterior tendon (TPT) dysfunction. Although open surgical procedures for advanced TPT disease have led to excellent outcomes, disagreement persists concerning the correct management algorithm for early TPT dysfunction. Recent developments in needle tendoscopy have provided a minimally invasive option for direct evaluation and intervention throughout the forefoot, midfoot, and hindfoot. The goal of this manuscript is to describe the technique for performing in-office needle tendoscopy targeting the TPT with a discussion of indications and opportunities afforded by an in-office procedure over the traditional operating room suite.

Abstract
BACKGROUND Bedside needle arthroscopy of the ankle under local anesthesia has been proposed for intra-articular delivery of injectable agents. Accuracy and tolerability of this approach in the clinical setting–including patients with end-stage ankle pathology and/or a history of prior surgery–is not known.
AIM To assess clinical accuracy and tolerability of bedside needle arthroscopy as a delivery system for injectable agents into the tibiotalar joint.
METHODS This was a prospective study that included adult patients who were scheduled for an injection with hyaluronic acid to the tibiotalar joint. In our center, these injections are used as a last resort prior to extensive surgery. The primary outcome was injection accuracy, which was defined as injecting through the arthroscopic cannula with intra-articular positioning confirmed by a clear arthroscopic view of the joint space. Secondary outcome measures included a patient-reported numeric rating scale (NRS, 0-10) of pain during the procedure and willingness of patients to return for the same procedure. NRS of ankle pain at rest and during walking was collected at baseline and at 2-wk follow-up. Complications were monitored from inclusion up to a 2-wk control visit.
RESULTS We performed 24 inspection-injections. Eleven (46%) participants were male, and mean age was 46.8 ± 14.5 years. Osteoarthritis was the indication for injection in 20 (83%) cases, of which 8 (33%) patients suffered from osteoarthritis Kellgren-Lawrence grade IV, and 10 (42%) patients from Kellgren-Lawrence grade III. An osteochondral defect was the indication for injection in 4 (17%) cases. A history of ankle surgery was present in 14 (58%) participants and a history of multiple ankle surgeries in 11 (46%) participants. It was possible to confirm accuracy in 21 (88%) procedures. The 3 (12%) participants where needle arthroscopy did not reach a clear view of the joint space all suffered from Kellgren-Lawrence grade IV osteoarthritis. Pain during the procedure was reported with a median of 1 [interquartile ranges (IQR): 0–2]. Willingness to return was 100%. Pain in rest decreased from a median NRS of 4 (IQR: 2–7) at baseline to a median of 3 (IQR: 1–5) at follow-up (P < 0.01). Pain during walking decreased from a median NRS of 8 (IQR: 6–9) to a median of 7 (IQR: 4–8) (P < 0.01). Infections or other complications were not encountered.
CONCLUSION Clinical accuracy and tolerability of bedside needle arthroscopy of the ankle as a delivery system for injectable agents are excellent. Accuracy was 100% in patients without total ventral joint obliteration.

Abstract
OBJECTIVE To evaluate the effect of intra-articular injection of autologous micronized adipose tissue (MAT) with ankle arthroscopic debridement in patients with advanced-stage posttraumatic osteoarthritis (PTOA) of ankle. DESIGN A retrospective cohort study investigating patients treated with arthroscopic debridement and autologous MAT injection for ankle PTOA was performed. Patients with Kellgren-Lawrence (KL) grade 3 to 4 were included. Visual analogue scale (VAS), Foot and Ankle Outcome Scores (FAOS), and patient satisfaction were evaluated. RESULTS A total of 19 patients (19 ankles) were included (KL grade 3, 8 patients; grade 4, 11 patients). At a mean follow-up time of 14.3 months (range, 7-23 months), the mean FAOS subscales for pain and quality of life significantly increased from 48.8 and 20.1 preoperatively to 61.1 and 30.1 (P = 0.029 and 0.048, respectively). The mean VAS score significantly improved from 6.1 to 3.8 (P = 0.003) at final follow-up. A total of 10.5% (2/19) of patients were very satisfied, 31.6% (6/19) satisfied, 26.3% (5/19) neutral, 21.1% (4/19) unsatisfied, and 10.5% (2/19) very unsatisfied with their outcomes. The overall FAOS score demonstrated a significant difference in pre- to postoperative change with 14.8 for KL grade 3 and 5.9 for KL grade 4 (P = 0.048). CONCLUSIONS Autologous MAT injection is a safe and potentially beneficial procedure for advanced-stage ankle PTOA as an adjunct to arthroscopic debridement, although more than one-third of patients were unsatisfied with the procedure. This procedure may be more beneficial for KL grade 3 patients than grade 4 patients. However, future investigations are necessary to define the role of MAT for ankle PTOA.

Abstract
Background: There is a paucity of data regarding osteochondral lesions of the tibial plafond (OLTPs), in part because they are far less common than osteochondral lesions of the talus. Purpose: To evaluate the topographical characteristics of OLTPs and outcomes after surgical intervention, while analyzing the level of evidence (LOE) and quality of evidence (QOE) of the included studies. Study Design: Systematic review; Level of evidence, 4. Methods: A systematic review of the MEDLINE, EMBASE, and Cochrane Library databases was performed in accordance with PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Studies reporting clinical data for OLTPs were included. The LOE and QOE of the included studies were evaluated using a 5-level grading system and the modified Coleman Methodology Score, respectively. Results: Included were 20 studies with 426 OLTPs; 4 studies were LOE 2 and 16 studies were LOE 4. Overall, 86.7% of OLTPs were associated with a traumatic history and/or previous ankle sprain. OLTPs were most commonly located in the centromedial region of the tibial plafond (30.4%), with the fewest number of OLTPs found in the anteromedial region of the tibial plafond (3.9%). In 17 of the studies, a total of 46.9% of OLTPs were associated with coexisting osteochondral lesions of the talus. The most frequently used surgical technique to treat OLTPs was microfracture, which resulted in good clinical outcomes at midterm follow-up. Conclusion: The results of this systematic review indicated that OLTPs are frequently preceded by ankle trauma and are often associated with coexisting osteochondral lesions of the talus. Clinical outcomes after arthroscopic intervention appear to produce good results in the midterm, but the low LOE, poor QOE, marked heterogeneity, and underreporting of the data confound any recommendation based on this systematic review.

Abstract
BACKGROUND There appears to be a close relationship between deformities at the knee joint and at the hindfoot in patients with knee osteoarthritis (OA). Despite this intrinsic link, there is a dearth of studies investigating alterations in hindfoot alignment following total knee arthroplasty (TKA) in patients with knee OA.
AIM To evaluate changes in alignment of the hindfoot following TKA, foot and ankle clinical outcomes in terms of subjective clinical scoring tools following surgical intervention, and to analyse the level of evidence (LOE) and quality of evidence (QOE) of the included studies.
METHODS MEDLINE, EMBASE and Cochrane Library databases were systematically reviewed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Studies reporting changes in the postoperative alignment of the hindfoot following TKA were included. The level and QOE were recorded and assessed.
RESULTS Eleven studies with a total of 1142 patients (1358 knees) met the inclusion/ exclusion criteria. Six studies were of LOE II and 5 studies were of LOE III. Patients with preoperative varus knee deformity and valgus hindfoot deformity demonstrated improvement in hindfoot alignment post TKA. Patients with preoperative varus knee deformity and varus hindfoot deformity demonstrated no improvement in hindfoot alignment following TKA. Twelve different radiographic parameters were used to measure the alignment of the hindfoot across the included studies, with the tibio-calcaneal angle most frequently utilised (27.3%).
CONCLUSION This systematic review demonstrated that the hindfoot may display compensatory changes in alignment following TKA in patients with knee OA. However, the marked heterogeneity between the included studies and poor QOE limits any meaningful cross sectional comparisons between studies. Further, well designed studies are necessary to determine the changes and outcomes of hindfoot alignment following TKA.

Abstract
The purpose of this study was to provide an overview of the available evidence on peroneal tendon tears and the outcomes after surgical intervention. A systematic review of the literature was performed using MEDLINE, Embase, and Cochrane. Criteria for inclusion were clinical studies reporting outcomes after treatment for peroneal tendon tear within the last 10 years. Nine studies evaluating 336 patients (146 males/190 females) and 336 ankles were included in this review. The mean age of included patients was 46.3 years (range, 46-56.9 years). The weighted mean follow-up was 23.82 months (range 9.2-78 months. Five surgical interventions were reported: primary repair with tenodesis, primary repair without tenodesis, FDL tendon transfer, FHL tendon transfer, and allograft reconstruction. Four studies recorded the AOFAS score, with a weighted mean preoperative score of 69.58 and a weighted mean postoperative score of 88.82. Six studies measured the VAS score showing an improvement from a mean weighted preoperative score of 4.68 to a mean weighted postoperative score of 1.2. FAAM score was measured in 3 studies, which showed an improvement from 41.1 preoperatively to 84.4 postoperatively. The average overall complication rate was 38.7% (130/336) with the most commonly reported minor complication being ankle pain, which made up 46.2% of all minor complications (56/121). Primary repair without tenodesis was associated with a higher complication rate compared to any other surgical intervention (p=.001176). The current systematic review showed that overall clinical outcomes were positive in lieu of the different modalities of surgical intervention for peroneal tendon tears.

Abstract
PURPOSE To evaluate the effectiveness of extracellular matrix cartilage allograft (EMCA) as an adjuvant to bone marrow stimulation (BMS) compared with BMS alone in the treatment of osteochondral lesions of the talus. METHODS A retrospective cohort study comparing patients treated with BMS with EMCA (BMS-EMCA group) and BMS alone (BMS group) between 2013 and 2019 was undertaken. Clinical outcomes were evaluated with the Foot and Ankle Outcome Score (FAOS) preoperatively and postoperatively. Postoperative magnetic resonance imaging (MRI) scans were evaluated using the modified Magnetic Resonance Observation of Cartilage Repair Tissue score. Comparisons between groups were made with the Mann-Whitney U test for continuous variables and the Fisher exact test for categorical variables. RESULTS Twenty-four patients underwent BMS with EMCA (BMS-EMCA group), and 24 patients underwent BMS alone (BMS group). The mean age was 40.8 years (range, 19-60 years) in the BMS-EMCA group and 47.8 years (range, 24-60 years) in the BMS group (P = .060). The mean follow-up time was 20.0 months (range, 12-36 months) in the BMS-EMCA group and 26.9 months (range, 12-55 months) in the BMS group (P = .031). Both groups showed significant improvements in all FAOS subscales. No significant differences between groups were found in all postoperative FAOS values. The mean Magnetic Resonance Observation of Cartilage Repair Tissue score in the BMS-EMCA group was higher (76.3 vs 66.3) but not statistically significant (P = .176). The MRI analysis showed that 87.5% of the BMS-EMCA patients had complete infill of the defect with repair tissue; however, fewer than half of the BMS patients (46.5%) had complete infill (P = .015). CONCLUSIONS BMS with EMCA is an effective treatment strategy for osteochondral lesions of the talus and provides better cartilage infill in the defect on MRI. However, this did not translate to improved functional outcomes compared with BMS alone in the short term. Additionally, according to analysis of the minimal clinically important difference, there was no significant difference in clinical function scoring between the 2 groups postoperatively. LEVEL OF EVIDENCE Level III, retrospective comparative study.

Abstract
PURPOSE (1) To determine the rate of return to play following autologous osteochondral transplantation (AOT) for osteochondral lesions of the talus (OLT) and (2) report subsequent rehabilitation protocols. METHODS A systematic review of the PubMed, Embase, and The Cochrane Library databases was performed according to the PRISMA guidelines based on specific eligibility criteria. Return to play data was meta-analysed and subsequent rehabilitation protocols were summarised. Level of evidence and quality of evidence (Zaman's criteria) were also evaluated. RESULTS Nine studies that totalled 205 ankles were included for review. The mean follow-up was 44.4 ± 25.0 (range 16-84) months. The mean OLT size was 135.4 ± 56.4 mm2. The mean time to return to play was 5.8 ± 2.6 months. The mean rate of return to play was 86.3% (range 50-95.2%), with 81.8% of athletes returning to pre-injury status. Based on the fixed-effect model, the rate of return to play was 84.07%. Significant correlation was found between increase age and decrease rate of return to play (R2 = 0.362, p = 0.00056). There was no correlation between OLT sizes and rate of return to play (R2 = 0.140, p = 0.023). The most common time to ankle motion post-surgery was immediately and the most common time to full weight-bearing was 12 weeks. CONCLUSIONS This systematic review indicated a high rate of return to play following AOT in the athletic population. Size of OLT was not found to be a predictor of return to play, whereas advancing age was a predictor. Rehabilitation protocols were largely inconsistent and were primarily based on individual surgeon protocols. However, the included studies were of low level and quality of evidence. LEVEL OF EVIDENCE Level IV.

Abstract
Background: Plantar fasciitis is the most common cause of plantar heel pain. Several
recent randomized control trials (RCTs) have been published comparing the
use of platelet-rich plasma (PRP) and corticosteroids (CSs) for the
treatment of plantar fasciitis. Purpose: To perform a systematic review of RCTs to compare whether PRP or CS
injections result in decreased pain levels and improved patient outcomes in
the treatment of plantar fasciitis. Study Design: Systematic review; Level of evidence, 1. Methods: Medline, EMBASE, and the Cochrane Library were screened according to the
PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses)
guidelines to identify RCTs comparing PRP and CS injections for plantar
fasciitis. The visual analog scale (VAS) pain scores and the American
Orthopaedic Foot and Ankle Society (AOFAS) scores were compared between
groups at 1, 1.5, 3, 6, and 12 months, where possible. Statistical analysis
was performed using RevMan, and P < .05 was considered
to be statistically significant. Results: A total of 9 RCTs were identified comparing 239 patients with PRP with 240
patients with CS injections. At the follow-up time points, including 1-1.5,
3, 6, and 12 months, there were statistically significant differences in VAS
scores in favor of PRP (P = .004, P <
.00001, P < .00001, and P < .00001,
respectively). At 1 and 3 months, there was no difference in AOFAS scores
(P = .76 and P = .35, respectively).
However, at 6 and 12 months, there was a difference in AOFAS scores in favor
of PRP (P < .00001 and P < .00001,
respectively). Conclusion: In patients with chronic plantar fasciitis, the current clinical evidence
suggests that PRP may lead to a greater improvement in pain and functional
outcome over CS injections.

Abstract
PURPOSE The purpose of this meta-analysis was to analyze the current comparative studies of arthroscopic and open techniques for lateral ankle ligament repair to treat chronic lateral ankle instability. METHODS A systematic search of MEDLINE, EMBASE and Cochrane Library databases was performed during February 2018. Included studies were evaluated with regard to level of evidence and quality of evidence using the Modified Coleman Methodology Score. Total number of patients, patient age, follow-up time, gender ratio, surgical technique, surgical complications, complication rate, recurrent instability or revision rate, clinical outcome measures and percentage of patients who returned to sport at previous level were also evaluated. Statistical analysis was performed using RevMan, and a p value of < 0.05 was considered to be statistically significant. RESULTS Four comparative studies for a total of 207 ankles were included. There was a significant difference in favor of arthroscopic repair with regard to AOFAS score, and there was no significant difference with regard to Karlsson score. There was a statistically significant difference in AOFAS score in favor of the arthroscopic repair (MD; 1.41, 95% CI 0.29-2.52, I2 = 0%, p < 0.05). There was no statistically significant difference in Karlsson score (MD; 0.00, 95% CI - 3.51 to 3.51, I2 = 0%, n.s.). There was no statistically significant difference in total, nerve, or wound complications. CONCLUSIONS The current meta-analysis found that short-term AOFAS functional outcome scores were significantly improved with arthroscopic lateral ankle repair compared to open repair. There was no significant difference between arthroscopic and open repair with regards to Karlsson functional outcome score, total complication rate, or the nerve and wound complication subsets with the included studies with at least 12 months of follow-up. However, the current evidence is still limited, and further prospective trials with longer follow-up are needed. LEVEL OF EVIDENCE III.

Abstract
Background: Bone marrow stimulation (BMS) is a common surgical intervention in the treatment of small osteochondral lesions of the talus (OLTs). Evidence has shown good clinical outcomes after BMS in the short term, but several studies have shown less favorable results at midterm and long-term follow-up because of fibrocartilaginous repair tissue degeneration. Purpose: To evaluate the clinical and radiological outcomes of BMS in the treatment of primary OLTs at midterm and long-term follow-up and to investigate reported data in these studies. Study Design: Systematic review; Level of evidence, 4. Methods: A systematic search of the MEDLINE, Embase, and Cochrane Library databases was performed in accordance with PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Clinical and radiological outcomes as well as reported data were evaluated. Results: A total of 15 studies comprising 853 patients (858 ankles) were included at a weighted mean follow-up time of 71.9 months. There were 9 studies that used the American Orthopaedic Foot & Ankle Society (AOFAS) score, with a weighted mean postoperative score of 89.9. There were 3 studies that measured postoperative magnetic resonance imaging results in the midterm using the MOCART (magnetic resonance observation of cartilage repair tissue) scoring system and showed 48% of patients with complete filling, 74% with complete integration, and 76% with surface damage. There was a complication rate of 3.4% and a reoperation rate of 6.0% after BMS in the midterm. Conclusion: This systematic review found good clinical outcomes after BMS at midterm follow-up for primary OLTs. Radiological outcomes showed repair tissue surface damage in the majority of patients, which may be a harbinger for long-term problems. Data were variable, and numerous data were underreported. Further high-quality studies, a validated outcome scoring system, and further radiological reports at midterm follow-up are required to accurately assess the success of BMS in the midterm.

Abstract
BACKGROUND Operative treatment is indicated for unstable syndesmosis injuries, and approximately 20% of all ankle fractures require operative fixation for syndesmosis injuries. PURPOSE To perform a meta-analysis of randomized controlled trials evaluating clinical outcomes between suture button (SB) and syndesmotic screw (SS) fixation techniques for syndesmosis injuries of the ankle. STUDY DESIGN Meta-analysis. METHODS A literature search was performed according to the PRISMA guidelines to identify randomized controlled trials comparing the SB and SS techniques for syndesmosis injuries. Level of evidence was assessed per the criteria of the Oxford Centre for Evidence-Based Medicine. Statistical analysis was performed with RevMan, and a P value ≤.05 was considered statistically significant. RESULTS Five clinical studies were identified, allowing comparison of 143 patients in the SB group with 142 patients in the SS group. Patients treated with the SB technique had a higher postoperative American Orthopaedic Foot & Ankle Society score at a mean 20.8 months (95.3 vs 86.7, P < .001). The SB group resulted in a lower rate of broken implants (0.0% vs 25.4%, P < .001), implant removal (6.0% vs 22.4%, P = .01), and joint malreduction (0.8% vs 11.5%, P = .05) as compared with the SS group. CONCLUSION The SB technique results in improved functional outcomes as well as lower rates of broken implant and joint malreduction. Based on the findings of this meta-analysis, the SB technique warrants a grade A recommendation by comparison with the SS technique for the treatment of syndesmosis injuries.

Abstract
PURPOSE To assess the effects of medical comorbidities on the incidence of surgical site infection following primary Achilles tendon repair. A secondary aim was to assess the effects of specific medical comorbidities on the cost and extent of healthcare utilization related to surgical site infection following primary Achilles tendon repair. METHODS 24,269 patients undergoing primary Achilles tendon repair between 2005 and 2012 were examined. Current Procedural Terminology codes for primary Achilles tendon repair, and incision and drainage were used to search for and compile patient data from the United Healthcare Orthopedic and Medicare databases. Primary outcome measures regarding surgical site infection following primary Achilles tendon repair included the rate of occurrence, cost, and duration of treatment. RESULTS Patients with one or more preexisting medical comorbidities at the time of surgery had an increased rate of surgical site infection compared to those without. Diabetes and vascular complications were associated with the highest surgical site infection rates. The rate of surgical incision and drainage was higher in patients with cardiac arrhythmias and uncomplicated hypertension. The presence of a medical comorbidity significantly increased the cost and duration of surgical site infection treatment. CONCLUSIONS Medical comorbidities can complicate the postoperative course for patients undergoing Achilles tendon repair, which increases the cost of care and duration of treatment. A better understanding of the relationship between each medical comorbidity and surgical site infections following Achilles tendon repair may be ascertained with additional prospective studies, thus, allowing for a more accurate evaluation and stratification of surgical candidates to improve patient outcomes.

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 Despite the promising clinical results of autologous osteochondral transplantation in the treatment of osteochondral lesions of the talus, the occurrence of knee donor-site morbidity remains a concern. However, the proportion of patients experiencing donor-site morbidity is not well established because of important variations in estimates drawn by heterogeneous studies with loss to followup, often made at short-term (< 1 year). Therefore, both a meta-analysis of studies that assumed no patients lost to followup had donor-site morbidity and assumed all patients lost to followup had donor-site morbidity may help to estimate the true risk of donor-site morbidity. QUESTIONS/PURPOSES To evaluate the proportion of patients who developed knee donor-site morbidity after autologous osteochondral transplantation for osteochondral lesion of the talus, by (1) meta-analysis of the proportion of patients experiencing donor-site morbidity in the best-case scenario as reported, in which no patients lost to followup were assumed to have donor-site morbidity and (2) meta-analysis of the percentage of patients who had donor-site morbidity in the worst-case scenario, in which all patients lost to followup were assumed to have donor-site morbidity and (3) present the characteristics of studies associated with the reporting of donor-site morbidity. METHODS A systematic search of the PubMed, Embase and The Cochrane Library databases was performed from their inception to October 2017 according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The inclusion criteria were clinical studies that reported knee donor-site morbidity after autologous osteochondral transplantation for osteochondral lesion of the talus, mean followup ≥ 1 year, full-text studies published in a peer-review journal and written in English. Quality of evidence (Case Series Quality Appraisal Checklist), sample size, mean patient age, study design, mean followup time, and observed rate of knee donor-site morbidity were evaluated. Twenty-six studies with 915 ankles (904 patients) were included in the systematic review and meta-analysis. Approximately half of the included studies were of small cohort (n < 30, 12 studies), and 12 of 26 studies did not report at all on loss to followup. In the studies that reported loss to followup (14 of 26), a total of 32 patients (35 ankles) were reported lost. Random-effects models were used to estimate the risk of donor-site morbidity as between-study heterogeneity was determined to be high in both meta-analyses that assumed that no patients lost to followup experienced donor-site morbidity (I = 82.1%) and the one that assumed all patients lost to followup experienced donor-site morbidity (I = 88.7%). Multivariable metaregression was used to estimate the association between study characteristics and the observed proportion of patients who experienced of donor-site morbidity. If there was evidence of an association between a study characteristic and proportion, a subgroup analysis was performed. RESULTS The estimated proportion of donor-site morbidity was 6.7% (95% confidence interval [CI], 2.8-11.8), assuming that no patients lost to followup experienced donor-site morbidity and 10.8% (95% CI, 4.8-18.3) assuming that all patients lost to followup experienced donor-site morbidity after a mean followup of 43.8 ± 24.7 months (range, 15.9-120 months). There was a negative association between study sample size and proportion of donor-site morbidity (β = -0.26; 95% CI, -0.39 to -0.12; p < 0.001 assuming that no patients lost to followup experienced donor-site morbidity and β = -0.31; 95% CI, -0.48 to -0.13; p < 0.001 assuming that all patients lost to followup experienced donor-site morbidity); that is, as study size increased, the proportion of patients reported with donor-site morbidity decreased. In larger studies (n ≥ 30), the estimated percentage of donor-site morbidity was 2.8% (95% CI, 1.2%-5.0%; I = 47.6%) assuming that no patients lost to followup experienced donor-site morbidity, and 5.0% (95% CI, 2.1%-9.0%; I = 74.5%) assuming all patients lost to followup experienced donor-site morbidity. High between-study heterogeneity (differences in methodology) could not be completely explained by variability in study sample size, mean patient age, design, or mean followup time, and may be attributable to other factors such as inconsistent definitions of donor-site morbidity. CONCLUSIONS The estimated proportion of donor-site morbidity after autologous osteochondral transplantation for osteochondral lesion of the talus ranged from 6.7% to 10.8% in the current meta-analysis. However, subgroup analysis demonstrated that larger studies (n ≥ 30) estimated a lower donor-site morbidity risk (< 5.0%) than smaller studies (n < 30). This estimate should be interpreted in light of the fact that nearly half of the included studies did not report on loss to followup, and so their estimates of donor-site morbidity may be low. In addition, high between-study heterogeneity and the inclusion of predominantly retrospective studies with small sample sizes likely contributed to estimates that suffered from a high risk of bias, probably in favor of the surgical treatment being studied. LEVEL OF EVIDENCE Level IV, therapeutic study.

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
Regenerative cell therapies are emerging as promising treatments for numerous musculoskeletal conditions, including knee osteoarthritis (OA). Adipose-derived stem cells and possibly other adipose-based therapies have a greater chondrogenic potential than stem cells derived from bone marrow, and thus a lot of attention is being placed on them as potential regenerative agents in the treatment of knee OA. Several types of adipose-based therapies have good basic science and preclinical data supporting their translation to human therapeutic intervention. Cultured, adipose-derived stem cells appear to be good source of bioactive cells with convenient accessibility, relative abundance, and well-documented regenerative capacity. Non-culture expanded adipose-based therapy, in the forms of stromal vascular fraction and most recently micronized adipose tissue (MAT), have been utilized in patients to treat OA and other cartilage abnormalities with encouraging preliminary data. These adipose-based therapies have shown a lot of therapeutic potential; however, because of the regulatory restrictions on enzymatic isolation and cell expansion, only MAT is currently available in clinical practice in the United States. While no serious adverse reactions have been reported, adipose-derived therapies also have the potential for adverse reactions including inflammation and infection. The current review provides an update on the latest research and presents this evidence on the therapeutic potential of adipose-based therapies in the treatment of knee OA.

Abstract
OBJECTIVE Despite the mechanical and biological roles of subchondral bone (SCB) in articular cartilage health, there remains no consensus on the postoperative morphological status of SCB following bone marrow stimulation (BMS). The purpose of this systematic review was to clarify the morphology of SCB following BMS in preclinical, translational animal models. DESIGN The MEDLINE and EMBASE databases were systematically reviewed using specific search terms on April 19, 2016 based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The morphology of the SCB was assessed using of microcomputed tomography (bone density) and histology (microscopic architecture). RESULTS Seventeen animal studies with 520 chondral lesions were included. The morphology of SCB did not recover following BMS. Compared with untreated chondral defects, BMS resulted in superior morphology of superficial SCB and cartilage but inferior morphology (specifically bone density, P < 0.05) of the deep SCB. Overall, the use of biological adjuvants during BMS resulted in the superior postoperative morphology of SCB. CONCLUSIONS Alterations in the SCB following BMS were confirmed. Biologics adjuvants may improve the postoperative morphology of both SCB and articular cartilage. Refinements of BMS techniques should incorporate consideration of SCB damage and restoration. Investigations to optimize BMS techniques incorporating both minimally invasive approaches and biologically augmented platforms are further warranted.

Abstract
PURPOSE To clarify if the use of concentrated bone marrow aspirate (CBMA) would affect both postoperative functional outcomes and magnetic resonance imaging (MRI) outcomes compared with those of autologous osteochondral transplantation (AOT) alone; in addition, to assess the efficacy of CBMA reducing the presence of postoperative cyst formation following AOT in the treatment of osteochondral lesions of the talus. METHODS Fifty-four (92%) of 59 eligible patients who underwent AOT between 2004 and 2008 were retrospectively assessed at a minimum of 5-year follow-up. Twenty-eight patients were treated with AOT and CBMA (AOT/CBMA group) and 26 patients were treated with AOT alone (AOT-alone group). Clinical outcomes were evaluated using the Foot and Ankle Outcome Scores (FAOS) and Short-Form 12 (SF-12) preoperatively and at final follow-up. Postoperative MRI was evaluated with the modified Magnetic Resonance Observation of Cartilage Repair Tissue (MOCART) scoring system. Cyst formation was also evaluated on postoperative MRI. RESULTS The mean FAOS and SF-12 significantly improved in both the AOT/CBMA and AOT-alone groups, but there were no statistical differences between groups in FAOS (80.5 vs 75.5, P = .225) and SF-12 (71.1 vs 69.6, P = .756) at final follow-up. Additionally, there was no difference in the mean MOCART score (80.4 vs 84.3, P = .484); however, AOT/CBMA did result in a statistically lower rate of cyst formation (46.4% vs 76.9%, P = .022). No significant differences were found in the mean postoperative FAOS and SF-12 between patients with and without cysts postoperatively. CONCLUSIONS CBMA reduced postoperative cyst occurrence rate in patients treated with AOT; however, CBMA did not result in significant differences in medium term functional outcomes and MOCART score in patients who underwent AOT.

Abstract
Residual symptoms often persist even after successful operative reduction and internal fixation (ORIF) of ankle fractures. Concurrent ankle arthroscopic procedures (CAAPs) have been proposed to improve clinical outcomes; however, a dearth of evidence is available supporting this practice. The purpose of the present study was to investigate the reoperation and complication rates after ORIF of ankle fractures with and without CAAPs. Reoperations and complications after ORIF of ankle fractures were identified using the PearlDiver database from January 2007 to December 2011. The CAAPs included bone marrow stimulation, debridement, synovectomy, and unspecified cartilage procedures. Reoperation procedures consisted of ankle fracture repeat fixation, arthroscopic procedures, osteochondral autograft transfers, and ankle arthrodesis. Of the 32,307 patients who underwent ankle fracture fixation, 248 received CAAP and 32,059 did not. No significant difference was found in the reoperation rate between the 2 groups (7.7% versus 8.6%; odds ratio 0.89; 95% confidence interval 0.55 to 1.42; p = .61). Of the 248 patients in the CAAP group, 19 (7.7%) underwent reoperation, of which 13 (68.4%) were arthroscopic debridement and 6 were either ankle refixation or osteochondral autograft transfer. For the non-CAAP group, 3021 reoperation procedures were performed, consisting of ankle refixation in 83.2%, arthroscopic procedures in 14.3%, and ankle arthrodesis in 2.5%. The complication rate in the non-CAAP group included wound dehiscence in 2.4%, wound surgery in 0.4%, deep vein thrombosis in 0.8%, and pulmonary embolism in 0.4%. No complications were detected in the CAAP group. Ankle fracture fixation with CAAPs did not increase the postoperative reoperation rate compared with ankle fracture fixation without CAAPs.

Abstract
BACKGROUND There is a paucity of clinical studies that compare the efficacy of autograft and allograft in osteochondral transplantation for treatment of osteochondral lesions of the talus (OLT). The purpose of the present study was to compare the clinical and radiographic outcomes following osteochondral transplantation with autograft or allograft for OLT. METHODS A retrospective analysis comparing patients treated with autograft or allograft for OLT was performed. Clinical outcomes were evaluated with use of the Foot and Ankle Outcome Score (FAOS) and the Short Form-12 (SF-12) score. Magnetic resonance imaging (MRI) was evaluated with use of the Magnetic Resonance Observation of Cartilage Repair Tissue (MOCART) score. The rates of cyst occurrence, graft degradation, graft failure, and revision surgeries were also evaluated. RESULTS Twenty-five nonrandomized patients with autograft and 16 with allograft were included, with a mean follow-up of 26 months in the autograft group and 22 months in the allograft group. There were no significant differences among all demographic variables between the autograft and allograft groups. The mean postoperative FAOS was significantly higher in the autograft group (81.9; 95% confidence interval [CI]: 78.6 to 85.2) than in the allograft group (70.1; 95% CI: 63.7 to 76.5; p = 0.006). Similarly, the mean postoperative SF-12 scores were significantly higher in the autograft group (74.7; 95% CI: 71.0 to 78.4) than in the allograft group (66.1; 95% CI: 61.2 to 71.0; p = 0.021). MOCART scores were significantly better in the autograft group (87.1) than in the allograft group (75.5; p = 0.005). The rate of chondral wear on MRI was higher in the allograft group (53%) than in the autograft group (4%; p < 0.001). Cyst formation in the graft itself was more likely to occur in the allograft group (47%) than in the autograft group (8%; p = 0.017). The rate of secondary procedures for the graft was higher in the allograft group (25%) than in the autograft group (0%; p = 0.009). CONCLUSIONS In this small nonrandomized cohort study, the procedures performed with use of an autograft provided better clinical and MRI outcomes than the allograft procedures. The rate of chondral wear on MRI was higher with allograft than with autograft, and allograft-treated patients had a higher rate of clinical failure. LEVEL OF EVIDENCE Therapeutic Level III.

Abstract
PURPOSE The purpose of this systematic review is to evaluate the effects of adipose derived mesenchymal stem cells (ADSCs) in the treatment of osteoarthritis (OA) in the clinical setting. METHODS A literature search was performed in the MEDLINE, EMBASE, and The Cochrane Library Database up to January 2017 for inclusion and exclusion criteria. Criteria for inclusion were clinical studies demonstrating the effects of ADSCs on OA, and written in English. The following variables were analyzed: donor site, volume of adipose tissue, preparation of ADSCs, clinical outcomes, and complication rate. RESULTS Sixteen studies (knee: 14 studies, multiple joints: 1 study, ankle: 1 study) were included in this systematic review. All of the studies prepared ADSCs in the form of the stromal vascular fraction (SVF). Inconsistencies between studies were found with regards to reported clinical variability, donor sites of SVF, and reported clinical outcomes. Nine studies used either platelet-rich plasma (PRP) (7/16) or fibrin (4/16) or both PRP and Fibrin (1/16), as an adjunct at time of SVF injection. All of the studies reported an improvement in clinical outcomes with the use of SVF. Five studies reported a 90% satisfaction rate, and no study reported any complications with liposuction. Five studies reported on complications, with a 5% incidence of swelling and pain. CONCLUSIONS This systematic review demonstrated that ADSCs are currently used in the form of SVF. While SVF may produce favorable clinical outcomes with minimal risk of side effects on osteoarthritis, the variability in the data and the use of biological adjuvants have confounded the effectiveness of ADSCs. This study will help surgeons understand the limitations in the literature on ADSCs. LEVEL OF EVIDENCE Level IV, systematic review of level IV studies.

Abstract
PURPOSE Autologous osteochondral transplantation is an established treatment for large-sized osteochondral lesions of the talus (OLT) with excellent short term outcomes. However, few studies assess the outcomes of autologous osteochondral transplantation at mid-term follow-up. The purpose of the current systematic review was to evaluate the clinical outcomes of the autologous osteochondral transplantation procedure in the treatment of OLT at mid-term and long-term follow-up. METHODS A systematic search of the MEDLINE, EMBASE and Cochrane Library databases was performed in October 2017 based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Included studies were evaluated with regard to level of evidence (LOE) and quality of evidence (QOE) using the Coleman Methodology Score. Clinical outcomes, and complications were also evaluated. RESULTS Eleven studies, with 500 ankles were included at a mean 62.8 months follow-up. Seven studies used the American Orthopaedic Foot and Ankle Society (AOFAS) score. The weighted mean preoperative AOFAS score was 55.1 ± 6.1, and the postoperative score was 86.2 ± 4.5, with 87.4% of patients (132 of 151) being reported as excellent or good results. In total, 53 of the 500 patients (10.6%) had complications. The most common complication was donor site morbidity with 18 patients (3.6%) at final follow-up. Thirty-one patients (6.2%) underwent reoperations, and 5 ankles (1.0%) were regarded as failed autologous osteochondral transplantation. CONCLUSION The current systematic review demonstrated that good clinical and functional outcomes can be expected following autologous osteochondral transplantation for the treatment of OLT, with a low failure rate. The results from this study show patients can be reasonably counselled to expect good clinical outcomes in the mid-term. MRI and radiographs showed restoration of articular surface as well as a minimal presence of osteoarthritis at mid-term follow-up. However, as low level and quality of evidence and the variability of the data may confound the data, further well-designed studies are necessary to determine the effectiveness of autologous osteochondral transplantation in the treatment for OLT. LEVEL OF EVIDENCE IV.

Abstract
Background: The incidence of coexisting osteochondral lesions (OCLs) of the tibia and talus has been negatively correlated with successful clinical outcomes, yet these lesions have not been extensively characterized. Purpose: To determine the incidence of coexisting tibial and talar OCLs, assess the morphologic characteristics of these lesions, and evaluate whether these characteristics are predictive of outcome. Study Design: Case series; Level of evidence, 4. Methods: A total of 83 patients who underwent surgery for a talar OCL were evaluated for coexisting OCLs of the distal tibia with preoperative magnetic resonance images. Size, location, containment, International Cartilage Repair Society (ICRS) grade, patient age, and patient sex were analyzed for predictors of coexisting lesions or patient outcome. The talar and tibial surfaces were each divided into 9 zones, with 1 corresponding to the most anteromedial region and proceeding laterally and then posteriorly. The Foot and Ankle Outcome Score (FAOS) was evaluated pre- and postoperatively. Results: Twenty-six patients (31%) had coexisting tibial and talar OCLs, with 9 (35%) identified as kissing lesions. Age correlated with coexisting lesion incidence, as older patients were more likely to have a coexisting tibial OCL (P = .038). More than half of talar OCLs were found in zone 4 (61%), whereas the majority of tibial OCLs were located in zones 2, 4, and 5 (19% each). Patients with coexisting lesions were more likely to have a lateral talar OCL (P = .028), while those without a coexisting tibial lesion were more likely to have a talar OCL in zone 4 (P = .016). There was no difference in FAOS result or lesion size between patients with and without coexisting OCLs, but patients with coexisting lesions were more likely to have an ICRS grade 4 talar OCL (P = .034). For patients with coexisting lesions, kissing lesions were more likely to be located in zone 6 (P = .043). There was no difference in OCL size or containment between kissing and nonkissing coexisting OCLs. Conclusion: The incidence of coexisting talar and tibial OCLs may be more prevalent than what previous reports have suggested, with older patients being more likely to present with this pathology. The location of a talar OCL correlates with the incidence of a coexisting tibial OCL.

Abstract
BACKGROUND Subchondral bone marrow edema (BME) has been associated with articular cartilage loss, with the potential to be a negative prognostic indicator for clinical outcomes after microfracture. However, no single study has investigated the association between BME and clinical outcomes after microfracture for osteochondral lesions of the talus (OLTs) at midterm follow-up. PURPOSE To clarify the association between postoperative subchondral BME and clinical outcomes in patients treated with microfracture for OLTs at both short-term and midterm follow-up using a grading system that classified the extent of BME of the talus. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS Patients who underwent microfracture between 2008 and 2013 were assessed at 2- and 4-year postoperative follow-up. BME was evaluated using magnetic resonance imaging, and the presence of subchondral BME was determined with fat-suppressed T2-weighted sequences. Clinical outcomes were evaluated using the Foot and Ankle Outcome Score (FAOS). P < .05 was considered to be statistically significant. RESULTS Forty-three (83%) of 52 eligible patients were included. No significant differences were found in the FAOS between the BME and no BME groups at 2-year follow-up (83.1 ± 6.5 vs 88.6 ± 8.0, respectively; P = .109), but there was a significant difference at 4-year follow-up (77.5 ± 11.1 vs 84.7 ± 8.4, respectively; P = .041). A significant difference was found among BME grades at 4-year follow-up (grade 0: 84.7 ± 7.4, grade 1: 80.1 ± 10.5, grade 2: 74.0 ± 10.3, and grade 3: 67.5 ± 7.1; P = .035). A post hoc analysis showed significant differences between grades 0 and 2, 0 and 3, and 1 and 3 ( P = .041, .037, and .048, respectively). In addition, at 4-year follow-up, a significant correlation was noted between the FAOS and BME grade ( r = -0.453, P = .003) but not at 2-year follow-up ( r = -0.212, P = .178). Seventy-four percent of patients still had subchondral BME at 4-year follow-up after microfracture for OLTs. CONCLUSION Patients with subchondral BME at midterm follow-up after microfracture for OLTs had worse clinical outcomes than those without subchondral BME. In addition, the degree of subchondral BME at midterm follow-up was correlated with clinical outcomes. However, at short-term follow-up, there were no significant differences in clinical outcomes based on both the presence and degree of BME, and no correlation was found between clinical outcomes and the degree of BME. The current study suggests that BME at short-term follow-up is a normal physiological reaction. However, BME at midterm follow-up after microfracture for OLTs may be pathological and is associated with poorer clinical outcomes.

Abstract
PURPOSE The purpose of this systematic review was to evaluate the current studies on arthroscopic lateral ankle ligament repair for chronic lateral ankle instability. METHODS A systematic search of MEDLINE, EMBASE, and Cochrane Library databases was performed during August 2017. Included studies were evaluated with regard to level of evidence (LOE) and quality of evidence (QOE) using the Coleman Methodology Score. Variable reporting outcome data, clinical outcomes, and percentage of patients who returned to sport at previous level were also evaluated. RESULTS Eight studies for a total of 269 ankles were included; 87.5% of studies were LOE III or IV, and the QOE in all studies was of poor or fair quality. Preoperative American Orthopaedic Foot and Ankle Society (AOFAS) scores ranged from 41.2 to 69.9, and postoperative AOFAS scores ranged from 90.2 to 98. All studies using AOFAS score showed an increase in postoperative outcome score of 22.8 to 54.2 at a mean follow-up of 17.1 months. Five studies used Karlsson-Peterson scores with mean postoperative score of 88.5 (range, 76.2-93.6) at a mean follow-up of 21.2 months. The comparative studies showed similar clinical outcomes between arthroscopic and open procedures. The overall complication rate was 11.6% in the included studies. The overall rate of return to sport was 100%. CONCLUSIONS The current systematic review demonstrated that arthroscopic lateral ankle ligament repair yields favorable clinical outcomes in the short term. However, there is no clinical evidence to support the advantages of the arthroscopic procedure over the open procedure, and there are no long-term data currently available for the arthroscopic procedure. There was a relatively high complication rate (11.5%) associated with the arthroscopic procedures, although recent comparative studies demonstrated similar complication rates for both open and arthroscopic techniques. LEVEL OF EVIDENCE Level IV, systematic review of Level I, III, and IV studies.

Abstract
BACKGROUND Uncontained-type osteochondral lesions of the talus (OLTs) have been shown to have inferior clinical outcomes after treatment with bone marrow stimulation. While autologous osteochondral transplantation (AOT) is indicated for larger lesions, no study has reported on the prognostic significance of the containment of OLTs treated with the AOT procedure. PURPOSE To clarify the effect of the containment of OLTs on clinical and radiological outcomes in patients who underwent AOT for OLTs. STUDY DESIGN Case control study; Level of evidence, 3. METHODS A retrospective cohort study comparing patients with contained-type and uncontained-type OLTs was undertaken to include all patients who underwent AOT for the treatment of OLTs between 2006 and 2014. Analyses were performed by grouping the patients according to the containment type. Clinical outcomes were evaluated using the Foot and Ankle Outcome Score (FAOS) and the 12-Item Short Form Health Survey (SF-12) preoperatively and at final follow-up. Magnetic resonance imaging (MRI) at 2 years' follow-up was evaluated with the modified magnetic resonance observation of cartilage repair tissue (MOCART) score. Multivariate regression models were used to evaluate factors affecting postoperative FAOS, SF-12, and MOCART scores. RESULTS Ninety-four patients were included: 31 patients with a contained-type OLT and 63 patients with an uncontained-type OLT. The median patient age was 34 years (interquartile range [IQR], 28-48 years) in the contained-type group and 36 years (IQR, 27-46 years) in the uncontained-type group. The median follow-up time was 45 months (IQR, 38-63 months) in the contained-type group and 52 months (IQR, 40-66 months) in the uncontained-type group. The median FAOS and SF-12 scores improved significantly after surgery in both contained-type and uncontained-type lesions ( P < .001). The median postoperative FAOS score of patients with contained-type OLTs was higher than that of patients with uncontained-type OLTs (91.7 vs 85.0, respectively; P = .009), but no significant differences were found between the contained-type and uncontained-type groups for postoperative SF-12 and MOCART scores. The multivariate regression models showed that patients with contained-type OLTs had an approximately 10-point better score on the FAOS compared with patients with uncontained-type OLTs ( P = .006). There was a nonsignificant trend for the rate of cystic occurrence in uncontained-type OLTs to be higher than that of contained-type OLTs (55.6% vs 38.7%, respectively; P = .125). CONCLUSION Patients with contained-type OLTs experienced better clinical outcomes than those with uncontained-type OLTs after AOT for the treatment of OLTs. However, the AOT procedure still provided good clinical and MRI outcomes in both contained-type and uncontained-type OLTs at midterm follow-up.

Abstract
BACKGROUND Extracellular matrix cartilage allografts (EMCAs) and particulate cartilage allografts (PCAs) are relatively new biologics that may improve the quality of cartilage regeneration after bone marrow stimulation. The increasing popularity of these novel biologics in the treatment of osteochondral lesions (OCLs) of the knee and ankle joints prompts a systematic evaluation of their efficacies. PURPOSE The purpose of this systematic review was to clarify the effectiveness of EMCAs and PCAs on cartilage regeneration. STUDY DESIGN Systematic review; Level of evidence, IV. METHODS Two reviewers searched MEDLINE and Embase in February 2016 based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Predetermined variables from each study were extracted and analyzed. RESULTS For EMCAs, 1 in vitro study and 2 clinical studies for OCLs of the ankle joint were found. For PCAs, 3 in vitro studies, 5 clinical studies for OCLs of the knee joint, and 5 clinical studies for OCLs of the ankle joint were found. For all studies, in vitro chondrogenesis and clinical outcomes favored EMCAs and PCAs. However, the highest level of evidence was IV, and the methodological quality of evidence was indicated to be poor. CONCLUSION Both EMCAs and PCAs have yielded favorable outcomes in both in vitro and clinical studies. However, the available studies were of limited data with significant confounding factors. Therefore, it is unclear whether the effectiveness of these novel biologics is any greater than that of bone marrow stimulation alone in the repair of knee and ankle cartilage.

Abstract
PURPOSES There is a lack of substantial clinical evidence endorsing the clinical outcomes of osteotomy for peroneal tendon dislocations. The aim of this study was to compare the post-operative reoperation rates following osteotomy techniques and soft tissues procedures using large database in order to investigate the efficacy of bony techniques. METHODS Patients who underwent osteotomy and soft tissue procedures for peroneal tendon dislocations were identified and subsequently analysed using the United Healthcare Orthopedic and the Medicare datasets (PearlDiver Patient Record Database, PearlDiver Technologies Inc., Fort Wayne, IN). The investigated period was from 2005 to 2012. The annual incidence, gender distribution, and incidences of reoperation and wound dehiscence following primary operative procedures were determined in these cohorts. RESULTS Of 6122 patients who received operative treatment for peroneal tendon dislocations, 1416 patients (23.1%) received the osteotomy technique, while 4706 (76.9%) were treated with the soft tissue techniques. The incidence of these operative procedures did not change significantly over the time periods of each database. In both databases, reoperation rates were 2.8% (40/1416) for osteotomy patients and 3.4% (158/4706) for soft tissue repair patients, with no statistical difference (2.8 vs. 3.4%. odds ratio 0.8, 95% confidence interval [CI] 0.6-1.2, [n.s.]) between them. Based on both databases, wound dehiscence occurred in 2.6% (37/1416) of the osteotomy patients and 2.3% (110/4706) of soft tissue repair patients with no statistical difference (2.6 vs. 2.3%, odds ratio 1.1, 95% CI 0.8-1.6, [n.s.]) between the groups. CONCLUSION The results of this study show that osteotomy techniques were frequently performed for patients with peroneal tendon dislocations. Nevertheless, osteotomy techniques for peroneal tendon dislocations are not associated with a lower risk of reoperation. In conclusion, soft tissue procedures offer a satisfactory method of treating peroneal tendon dislocations without any additional risk of reoperation when compared to osteotomy techniques that have potentially greater complication rates.

Abstract
BACKGROUND Microfracture is the most common cartilage-reparative procedure for the treatment of osteochondral lesions of the talus (OLTs). Damage to the subchondral bone (SCB) during microfracture may irreversibly change the joint-loading support of the ankle, leading to reparative fibrocartilage degradation over time. PURPOSE To investigate the morphological change in the SCB after microfracture for OLT by developing a novel magnetic resonance imaging (MRI) scoring system specifically for evaluating the SCB. Furthermore, this study assesses the influence of the morphological changes of the SCB on clinical outcomes based on the new score. STUDY DESIGN Case series; Level of evidence, 4. METHODS Forty-two patients who underwent microfracture for OLT were included. An SCB Health (SCBH) scoring system was developed according to the amount of edema, subchondral cyst diameter, and qualitative and thickness change in the SCB, with a total score of 12 indicating normal SCB. MRI was obtained postoperatively from 6 months to 1 year, 1 to 2 years, 2 to 4 years, and 4 to 6 years. The Foot and Ankle Outcome Score (FAOS) was evaluated preoperatively and at 2 years and final follow-up. RESULTS The mean patient age was 38.4 ± 15.6 years, with a mean follow-up of 51.7 ± 22.8 months. The mean FAOS improved significantly from 57.8 ± 14.4 preoperatively to 84.3 ± 7.2 at 24 months ( P < .001) and decreased to a final mean value of 77.1 ± 12.6 ( P < .001). The mean SCBH score decreased from 8.6 ± 1.9 preoperatively to 7.1 ± 1.8 on the first follow-up MRI ( P < .001) and significantly decreased to 5.9 ± 2.3 on the fourth follow-up MRI ( P < .001). Subchondral cysts were noticeably worse at the fourth follow-up MRI than at the first and second ( P < .001, P = .006, respectively). There was a positive correlation between the final FAOS and the SCBH score on the third and fourth follow-up MRI ( r = 0.55, P < .001; r = 0.70, P < .001, respectively), but no correlation was found on the first and second follow-up. CONCLUSION The SCBs following microfracture for OLT were not restored at midterm follow-up. There was a significant decrease of the overall SCBH score over time. Noticeably, subchondral cysts deteriorated over time consistently. In addition, the SCBH score at midterm follow-up was positively correlated with clinical outcomes. Lasting morphological changes in the SCB may be indicative of longer-term failure of the microfracture procedure.

Abstract
AIM To clarify the effectiveness of scaffold-based therapy for osteochondral lesions of the talus (OLT).
METHODS A systematic search of MEDLINE and EMBASE databases was performed during August 2016 and updated in January 2017. Included studies were evaluated with regard to the level of evidence (LOE) and quality of evidence (QOE) using the Modified Coleman Methodology Score. Variable reporting outcome data, clinical outcomes, and the percentage of patients who returned to sport at previous level were also evaluated.
RESULTS Twenty-eight studies for a total of 897 ankles were included; 96% were either LOE III or IV. Studies were designated as either of poor or fair quality. There were 30 treatment groups reporting six different scaffold repair techniques: 13 matrix-induced autologous chondrocyte transplantation (MACT), nine bone marrow derived cell transplantation (BMDCT), four autologous matrix-induced chondrogeneis (AMIC), and four studies of other techniques. The categories of general demographics (93%) and patient-reported outcome data (85%) were well reported. Study design (73%), imaging data (73%), clinical variables (49%), and patient history (30%) were also included. The weighted mean American Orthopaedic Foot and Ankle Society (AOFAS) score at final follow-up was: 86.7 in MACT, 88.2 in BMDCT, and 82.3 in AMIC. Eight studies reported that a weighted mean of 68.3% of patients returned to a previous level of sport activity.
CONCLUSION Scaffold-based therapy for OLT may produce favorable clinical outcomes, but low LOE, poor QOE, and variability of the data have confounded the effectiveness of this treatment.

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.
