Abstract
The treatment of osteochondral lesions of the talus (OLT) remains a topic of debate as no superior treatment has yet been identified. The current consensus is that it is crucial to incorporate lesion and patient characteristics into the treatment algorithm. One such lesion type is the OLT with a fragment, which may benefit from in situ fixation. Fixation preserves the native hyaline cartilage and offers a direct stabilization of the fragment with high-quality subchondral bone repair. This current concepts review describes the evidence-based clinical work-up, indications, surgical techniques, outcomes, and clinical pearls for fixation techniques of OLT from the Amsterdam perspective.

Autologous osteoperiosteal transplantation is effective in the treatment of single cystic osteochondral lesions of the talus and the prognostic impact of age should be emphasized. Knee Surg Sports Traumatol Arthrosc 2024. [PMID: 38819934 DOI: 10.1002/ksa.12301] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/10/2023] [Revised: 05/16/2024] [Accepted: 05/21/2024] [Indexed: 06/02/2024]
Abstract
PURPOSE To investigate the clinical efficacy and prognostic factors associated with autologous osteoperiosteal transplantation for the treatment of single cystic osteochondral lesions of the talus (OLT). METHODS The clinical data of patients with single cystic OLT undergoing autologous osteoperiosteal transplantation at the Department of Foot and Ankle Surgery of our hospital between 2018 and 2022, including complete follow-up, were retrospectively analyzed. Imaging data from each patient were imported into Mimics software to measure the surface area, volume and depth of the lesions. Then, the talus nine-compartment partitioning method was used to partition the injury site. Preoperative and final follow-up assessments were performed using the American Orthopaedic Foot and Ankle Society (AOFAS) score, visual analogue scale (VAS) for pain and 36-item Short-Form Health Survey (SF-36) to evaluate treatment efficacy and analyze prognostic factors. RESULTS Of the 31 patients with single cystic OLT with a complete set of follow-up data, there were 17 males and 14 females, with a mean age of 43.3 ± 13.6 years, a mean follow-up time of 30.1 ± 14.0 months and a mean illness duration of 30.4 ± 20.0 months. The postoperative final follow-up AOFAS score was 90.7 ± 5.5; this represented significant improvement when compared to the preoperative score of 57.0 ± 8.5 (P < 0.001). The final postoperative follow-up VAS score was 18.5 ± 8.3; this was significantly better than the preoperative score of 57.8 ± 8.7 (P < 0.001). The physical component summary (PCS) score and mental component summary (MCS) score on the SF-36 scale showed significant improvement at the final postoperative follow-up when compared to preoperative scores (p < 0.001). No other complications were observed during follow-up, such as wound infection or pain at the donor site. One of the patients showed less improvement, which may be related to premature weight-bearing or re-sprained ankle after surgery. There was no significant correlation between the duration of illness, gender and the location, depth, surface area and volume of the OLT and the postoperative scores. However, patient age showed a significant negative correlation with the postoperative SF-36 PCS and MCS scores. CONCLUSION Autologous osteoperiosteal transplantation for single cystic OLT demonstrated good clinical efficacy with a low incidence of complications. Furthermore, age represents an important factor influencing prognosis. LEVEL OF EVIDENCE Level II.

Improved Results From Medium- and Long-Term Outcomes of Autogenous Osteoperiosteal Grafting for Large Cystic Lesions of the Talus. Arthroscopy 2024; 40:1613-1622. [PMID: 37821015 DOI: 10.1016/j.arthro.2023.09.022] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/15/2023] [Revised: 09/02/2023] [Accepted: 09/13/2023] [Indexed: 10/13/2023]
Abstract
PURPOSE To investigate the medium and long-term follow-up outcomes of large cystic medial osteochondral lesions of the talus (OLTs) treated with autologous tibial osteoperiosteal grafts from the medial tibia and to explore the risk factors influencing the treatment outcomes. METHODS The retrospective study included 75 patients with large cystic medial OLTs who underwent autologous osteoperiosteal cylinder graft taken from the medial tibia between January 2004 and August 2018. They were assessed preoperatively and postoperatively using a visual analog scale, the Orthopedic Foot & Ankle Society Ankle-Hindfoot Scale (AOFAS), and short-form 36-item Short Form Health Survey score. Magnetic resonance observation of cartilage repair tissue, second-look arthroscopy, and biopsy were used to evaluate the grafting areas. RESULTS After a follow-up period of 6.3 years, the virtual analog scale score decreased to 1.47 ± 1.32, and the AOFAS and 36-item Short Form Health Survey scores increased to 82.78 ± 11.65 and 83.26 ± 8.49, respectively, all of which showed significant improvement over preoperative scores (P < .001), and the average magnetic resonance observation of cartilage repair tissue score was 82.6 ± 8.4 (56.0-91.6). Eight patients underwent a second-look arthroscopic examination and were rated by the International Cartilage Repair Society scale; of them, 2 patients were rated grade Ⅰ, 4 were rated grade Ⅱ, and 2 were rated grade Ⅲ. Three patients underwent grafting area biopsy during the second-look arthroscopy, and the results showed that the grafting areas were rich in chondrocytes. Large OLTs (≥200 mm2) and obesity (body mass index ≥25) were responsible for the poor improvement of AOFAS score, according to multivariate Cox regression analysis. CONCLUSIONS Autologous osteoperiosteal grafting was an effective treatment for large cystic medial OLTs, with effective cartilage regeneration in the grafted areas in the medium and long term. However, the large OLTs and obesity may reduce the treatment outcomes. LEVEL OF EVIDENCE Level IV, case series.

Abstract
BACKGROUND Press-fit Talar OsteoPeriostic grafting from the Iliac Crest (TOPIC) is a novel technique for the treatment of large osteochondral lesions of the talus. The purpose of the present study was to prospectively evaluate the 2-year clinical outcomes for patients with medial osteochondral lesions of the talus that were treated with the TOPIC procedure. METHODS Forty-three patients were prospectively assessed before and 24 months after the TOPIC procedure. All procedures were performed through a medial distal tibial osteotomy. Clinical assessment preoperatively and at 24 months of follow-up included determination of the Numeric Rating Scale (NRS) scores for pain during walking (primary outcome), at rest, during running, and during stair-climbing. The Foot and Ankle Outcome Score (FAOS) and the Mental Component Summary (MCS) score and Physical Component Summary (PCS) score of the Short Form-36 (SF-36) were also assessed. A computed tomography (CT) scan was performed 12 weeks postoperatively to assess union of the distal tibial osteotomy site and at 1 and 2 years postoperatively to assess consolidation of the graft as well as cyst development in the graft. RESULTS All enrolled patients were available for follow-up. The median NRS score for pain during walking improved from 7 points preoperatively to 2 points at 2 years postoperatively (p < 0.001). All other NRS scores for pain improved significantly. All FAOS subscale scores improved significantly, including those for pain (from 53 to 75), symptoms (from 50 to 61), activities of daily living (from 68 to 88), sports (from 30 to 55), and quality of life (from 19 to 38). The SF-36 PCS score improved from 43 to 48 (p < 0.001), and the MCS score changed from 28 to 26 (p > 0.05). There was a 100% rate of union of the osteotomy site at the distal tibia and 100% of the grafts showed consolidation at 1 and 2 years postoperatively. CONCLUSIONS The TOPIC procedure for large osteochondral lesions of the medial talar dome is an effective technique that resulted in significant improvement exceeding the minimal clinically important difference in pain scores (primary outcome) as well as in other outcomes, with 100% consolidation of the grafts.

Abstract
Purpose Ankle injuries are frequent sports injuries. Despite optimizing treatment strategies during recent years, the percentage of chronification following an ankle sprain remains high. The purpose of this review article is, to highlight current epidemiological, clinical and novel advanced cross-sectional imaging trends that may help to evaluate ankle sprain injuries. Methods Systematic PubMed literature research. Identification and review of studies (i) analyzing and describing ankle sprain and (ii) focusing on advanced cross-sectional imaging techniques at the ankle. Results The ankle is one of the most frequently injured body parts in sports. During the COVID-19 pandemic, there was a change in sporting behavior and sports injuries. Ankle sprains account for about 16-40% of the sports-related injuries. Novel cross-sectional imaging techniques, including Compressed Sensing MRI, 3D MRI, ankle MRI with traction or plantarflexion-supination, quantitative MRI, CT-like MRI, CT arthrography, weight-bearing cone beam CT, dual-energy CT, photon-counting CT, and projection-based metal artifact reduction CT may be introduced for detection and evaluation of specific pathologies after ankle injury. While simple ankle sprains are generally treated conservatively, unstable syndesmotic injuries may undergo stabilization using suture-button-fixation. Minced cartilage implantation is a novel cartilage repair technique for osteochondral defects at the ankle. Conclusion Applications and advantages of different cross-sectional imaging techniques at the ankle are highlighted. In a personalized approach, optimal imaging techniques may be chosen that best detect and delineate structural ankle injuries in athletes.

Abstract
Abstract
Purpose
Different surgical techniques to manage cartilage defects are available, including microfracture (MFx), autologous chondrocyte implantation (ACI), osteoarticular auto- or allograft transplantation (OAT), autologous matrix-induced chondrogenesis (AMIC). This study investigated the patient-related prognostic factors on the clinical outcomes of surgically treated knee and ankle cartilage defects.
Methods
This study followed the PRISMA statement. In May 2022, the following databases were accessed: PubMed, Google Scholar, Embase, and Scopus. All the studies investigating the outcomes of surgical management for knee and/or talus chondral defects were accessed. Only studies performing mesenchymal stem cells transplantation, OAT, MFx, ACI, and AMIC were considered. A multiple linear model regression analysis through the Pearson Product–Moment Correlation Coefficient was used.
Results
Data from 184 articles (8905 procedures) were retrieved. Female sex showed a positive moderate association with visual analogue scale at last follow-up (P = 0.02). Patient age had a negative association with the American Orthopaedic Foot and Ankle Score (P = 0.04) and Lysholm Knee Scoring Scale (P = 0.03). BMI was strongly associated with graft hypertrophy (P = 0.01). Greater values of VAS at baseline negatively correlate with lower values of Tegner Activity Scale at last follow-up (P < 0.0001).
Conclusion
The clinical outcomes were mostly related to the patients’ performance status prior surgery. A greater BMI was associated with greater rate of hypertrophy. Female sex and older age evidenced fair influence, while symptom duration prior to the surgical intervention and cartilage defect size evidenced no association with the surgical outcome. Lesion size and symptom duration did not evidence any association with the surgical outcome.

Abstract
Osteochondral lesions of the talus (OLT) are common following ankle trauma. Operative treatment is often required, with osteochondral autografting frequently performed for large or cystic lesions, or following failed primary surgery. The aim of this systematic review was to evaluate the current evidence for osteochondral autograft transfer system (OATS) in the management of OLT. A systematic search of the PubMed, EMBASE, Scopus, and Cochrane Library databases was performed based on the Preferred Reporting Items for Systematic Reviews (PRISMA) guidelines. Study quality was assessed using the modified Coleman Methodology Score (CMS). Meta-analysis was carried out using RevMan, version 5.4 (The Cochrane Collaboration, 2020). A total of 23 studies were included. The mean modified CMS was 48.1±7.47. Fourteen studies reported preoperative and postoperative Visual Analog Scale (VAS) and American Orthopaedic Foot & Ankle Score (AOFAS). The aggregate mean preoperative and postoperative VAS score across 14 studies was 6.47±1.35 and 1.98±1.18, respectively. Meta-analysis of seven studies on 210 patients found that OATS resulted in a significant reduction in VAS score compared to baseline (Mean Difference {MD} -4.22, 95% Confidence Interval {CI} -4.54 to -3.90, P < 0.0001). The aggregate mean preoperative and postoperative AOFAS scores across 14 studies were 56.41±8.52 and 87.14±4.8, respectively. Based on eight studies on 224 patients, OATS resulted in a significant improvement in AOFAS score compared to baseline (MD 29.70, 95% CI 25.68 to 33.73, P = < 0.0001). Donor site pain occurred in 9% of cases. Current evidence from low-quality studies suggests that OATS is a safe and effective treatment option for OLT, though it is associated with a risk of donor site morbidity.

Abstract
BACKGROUND It is unclear whether the results of osteochondral transplant using autografts or allografts for talar osteochondral defect are equivalent. PURPOSE A systematic review of the literature was conducted to compare allografts and autografts in terms of patient-reported outcome measures (PROMs), MRI findings, and complications. STUDY DESIGN Systematic review; Level of evidence, 4. METHODS This study was conducted according to the PRISMA guidelines. The literature search was conducted in February 2021. All studies investigating the outcomes of allograft and/or autograft osteochondral transplant as management for osteochondral defects of the talus were accessed. The outcomes of interest were visual analog scale (VAS) score for pain, American Orthopaedic Foot and Ankle Society (AOFAS) score, and Magnetic Resonance Observation of Cartilage Repair Tissue (MOCART) score. Data concerning the rates of failure and revision surgery were also collected. Continuous data were analyzed using the mean difference (MD), whereas binary data were evaluated with the odds ratio (OR) effect measure. RESULTS Data from 40 studies (1174 procedures) with a mean follow-up of 46.5 ± 25 months were retrieved. There was comparability concerning the length of follow-up, male to female ratio, mean age, body mass index, defect size, VAS score, and AOFAS score (P > .1) between the groups at baseline. At the last follow-up, the MOCART (MD, 10.5; P = .04) and AOFAS (MD, 4.8; P = .04) scores were better in the autograft group. The VAS score was similar between the 2 groups (P = .4). At the last follow-up, autografts demonstrated lower rate of revision surgery (OR, 7.2; P < .0001) and failure (OR, 5.1; P < .0001). CONCLUSION Based on the main findings of the present systematic review, talar osteochondral transplant using allografts was associated with higher rates of failure and revision compared with autografts at midterm follow-up.

Abstract
BACKGROUND In cases of large osteochondral lesions of the talus (OLTs), fresh structural or bulk osteochondral allograft transplantation has yielded favorable outcomes in several retrospective and few prospective case series. The purpose of this study was to prospectively evaluate patients who received fresh structural allograft transplantation of the talar shoulder. METHODS A prospective evaluation of patients who received a fresh structural allograft of an OLT was performed. Preoperative imaging included magnetic resonance imaging (MRI) and/or computed tomography (CT) with plain radiographs. The following patient-reported outcomes questionnaires were administered preoperatively and yearly after surgery: 36-Item Short-Form Health Survey (SF-36), visual analog scale (VAS) for pain, and the Short Musculoskeletal Functional Assessment (SMFA). Preoperative and postoperative imaging were evaluated for allograft assimilation, evidence of arthritic changes, or functional range of motion abnormalities. RESULTS Thirty-one patients with a mean age of 41.4 years (±14.1, range 18-69) underwent structural fresh osteochondral allograft transplantation to the talar shoulder and were included in this study. The mean follow-up was 56.2 months (±36.1, range 24-142). The majority of patients were female (n=17, 54.8%), reported some history of prior ankle trauma (n=21, 67.7%), and underwent prior ankle surgery (n=23, 74.2%). The mean lesion size on CT scan was 1879 mm3 (n = 27) compared to the mean lesion size of 3877 mm3 (n = 21) on MRI. There was a significant improvement in the mean preoperative VAS score (P < .0001), SF-36 score (P < .0005), SMFA bother index (P < .0015), and the SMFA function index (P < .0001) at final follow-up. A total of 15 (48.4%) patients underwent an additional surgery following their osteochondral allograft transplant, most commonly arthroscopic debridement or removal of hardware, performed at an average of 25.2 (±13.0) from their index procedure. There was one failure that required a total ankle replacement. The overall graft survival rate was 96.8%. CONCLUSION Fresh, structural allograft transplantation resulted in significant improvement in patient-reported postoperative pain and function in patients suffering from OLTs. The graft survival rate was 96.8% at a mean of 56.2 months follow-up, with half of patients requiring a second procedure. LEVEL OF EVIDENCE Level IV, prospective case series.

Operative treatment of talar osteochondral lesions is challenging with various treatment options. The aims were (i) to compare patient populations between the different treatment options in terms of demographic data and lesion size and (ii) to correlate the outcome with demographic parameters and preoperative scores.
Methods
A systemic review was conducted according to the PRISMA guidelines. The electronic databases Pubmed (MEDLINE) and Embase were screened for reports with the following inclusion criteria: minimum 2-year follow-up after operative treatment of a talar osteochondral lesion in at least ten adult patients and published between 2000 and 2020.
Results
Forty-five papers were included. Small lesions were treated using BMS, while large lesions with ACI. There was no difference in age between the treatment groups. There was a correlation between preoperative American Orthopaedic Foot and Ankle Society (AOFAS) score and change in AOFAS score (R = −0.849, P < 0.001) as well as AOFAS score at follow-up (R = 0.421, P = 0.008). Preoperative size of the cartilage lesion correlates with preoperative AOFAS scores (R= −0.634, P = 0.001) and with change in AOFAS score (R = 0.656, P < 0.001) but not with AOFAS score at follow-up. Due to the heterogeneity of the studies, a comparison of the outcome between the different operative techniques was not possible.
Conclusion
Patient groups with bigger lesions and inferior preoperative scores did improve the most after surgery.

Abstract
BACKGROUND Autologous osteochondral transplantation (AOT) using a cylindrical graft in the treatment of osteochondral lesions of the talus (OLTs) is typically indicated for patients with larger lesions. However, with lesions that are irregular in shape, the AOT graft may not completely replace the lesion. For these lesions, we utilize extracellular matrix cartilage allograft (EMCA) augmentation in AOT to act as a physiologic grout at the host-graft interface. PURPOSE To determine if the combination of EMCA with concentrated bone marrow aspirate (CBMA) would improve integration of the host-graft interface and subsequently reduce postoperative cyst formation after AOT. It was also hypothesized that EMCA in conjunction with CBMA would demonstrate improved MOCART (magnetic resonance observation of cartilage repair tissue) scores and functional outcome scores at a minimum 2 years after surgery. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS A retrospective analysis was performed comparing patients treated with AOT/CBMA alone and AOT with CBMA/EMCA. Clinical outcomes were evaluated with the Foot and Ankle Outcome Score. Magnetic resonance imaging appearance was evaluated with the use of the MOCART (magnetic resonance observation of cartilage repair tissue) score. Cyst formation was also evaluated on postoperative magnetic resonance imaging. RESULTS A total of 26 patients were included in the AOT + CBMA/EMCA group (10 male, 16 female), and 34 patients were included in the AOT/CBMA group (17 male, 17 female). The mean Foot and Ankle Outcome Score significantly improved in both groups (P < .001) across all subscales (symptoms, pain, activities of daily living, sports activities, and quality of life), but there was no significant difference between groups at final follow-up. There was no significant difference in mean MOCART scores between the groups (P = .118). In the AOT/CBMA group, 3 patients (8.8%) complained of knee pain, and 1 (2.9%) required additional surgery (hardware removal). In the AOT + CBMA/EMCA group, 2 patients (7.7%) complained of knee pain, and 6 patients (23%) required additional surgery (3 hardware removals and 3 arthroscopic debridements of scar tissue in the ankle). CONCLUSION We found that while EMCA with CBMA has benefit in regeneration and repair of OLT treated with bone marrow stimulation, there appears to be little benefit of EMCA over CBMA alone as a physiologic grout at the graft-host interface in OLT treated with AOT.

Abstract
BACKGROUND The present systematic review analysed the available literature to assess reliability of the Magnetic Resonance Observation of Cartilage Repair Tissue (MOCART) score in the evaluation of knee and ankle osteochondral lesions. METHODS All the studies using the MOCART score for knee and/or talus chondral defects were accessed in March 2021. A multivariate analysis was performed to assess associations between the MOCART score at last follow-up and data of patients at baseline, clinical scores and complications. A multiple linear model regression analysis was used. RESULTS The MOCART score evidenced no association with patient age (P = 0.6), sex (P = 0.1), body mass index (P = 0.06), defect size (P = 0.9), prior length of symptoms (P = 0.9) or visual analogue scale (P = 0.07). For chondral defects of the knee, no statistically significant association was found between the MOCART score and the International Knee Documentation Committee (P = 0.9) and with the Lysholm Knee Scoring Scales (P = 0.2), Tegner Activity Scale (P = 0.2), visual analogue scale P = 0.07), rate of failure (P = 0.2) and revision (P = 0.9). For chondral defect of the talus, no statistically significant associations were found between the MOCART score and the American Orthopedic Foot and Ankle Score (P = 0.3), Tegner Activity Scale (P = 0.4), visual analogue scale (P = 0.1), rate of failure (P = 0.1) and revision (P = 0.7). CONCLUSION The MOCART score demonstrated no association with patient characteristics and with the surgical outcome in patients who underwent surgical management for knee and talus chondral defects.

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: 7] [Impact Index Per Article: 2.3] [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
Osteochondral lesions of the talus (OLTs) are characterized by damage to the articular cartilage of the talus and its underlying subchondral bone. Up to 75% of OLTs are caused by trauma, such as an ankle sprain or fracture. Physical examination and imaging are crucial for diagnosis and characterization of an OLT. No superior treatment for OLTs exists. It is paramount that an evidence-based personalized treatment approach is applied to patients with OLTs because lesion and patient characteristics guide treatment. This current concepts review covers clinical and preclinical evidence on OLT etiology, presentation, diagnosis, and treatment, all based on the Amsterdam perspective.

Abstract
The management of symptomatic osteochondral lesions of the talus (OLTs) can be challenging. The number of ways of treating these lesions has increased considerably during the last decade, with published studies often providing conflicting, low-level evidence. This paper aims to present an up-to-date concise overview of the best evidence for the surgical treatment of OLTs. Management options are reviewed based on the size of the lesion and include bone marrow stimulation, bone grafting options, drilling techniques, biological preparations, and resurfacing. Although many of these techniques have shown promising results, there remains little high level evidence, and further large scale prospective studies and systematic reviews will be required to identify the optimal form of treatment for these lesions.

Abstract
We analyzed the characteristics of 112 consecutive patients who were operatively treated for osteochondral lesions of the talus from August 2014 to April 2019 in our hospital. The patients were divided into three age groups: young-adult (<40 years), middle-age (40-60 years) and old-age (>60 years). The basic clinical features, localization and size of the lesions, Hepple stage, and surgical procedures were compared among groups. Several significant differences were found on the characteristics of osteochondral lesions of the talus among age groups. There were more female patients in the old-age group (p<0.01), and old patients had a longer duration of symptoms (p<0.05). The OLTs in middle- and old-age patients were mostly located in the medial part of the talus with larger depth (p<0.01). Hepple stage 5, the cystic type, was very common in the old-age group (p<0.01). With regard to surgical procedures, more osteochondral autograft transplantations were applied in the old-age group (p<0.01). Female and deep medial talar subchondral cyst is the typical characteristics of patients over 60 years old. Age is an important factor that must be considered when choosing surgery procedure for patients with osteochondral lesions of the talus.

Abstract
PURPOSE To evaluate the long-term clinical and radiologic outcomes of third-generation autologous chondrocyte implantation (ACI) for the treatment of focal cartilage defects of the knee. METHODS Data capture was carried out between 2004 and 2018. Included were patients with cartilage defects of the knee joint with an International Cartilage Repair Society grade of III or higher treated with third-generation ACI who had a minimum follow-up period of 10 years. International Knee Documentation Committee scores and assessment of pain at rest and on movement using visual analog scale scores were captured preoperatively and at 6 months postoperatively, as well as annually thereafter. In addition, we performed magnetic resonance imaging examinations in 13 cases after 10 years. The MOCART (Magnetic Resonance Observation of Cartilage Repair Tissue) score was used to evaluate the ACI cartilage. RESULTS A total of 54 patients met the inclusion criteria. Of these, 30 reached the 10-year follow-up point and were included in this assessment. At 10 years postoperatively, all clinical outcome parameters showed a statistically significant improvement compared with the preoperative situation, with a responder rate of 70%. The average MOCART (Magnetic Resonance Observation of Cartilage Repair Tissue) score after 10 years was 59.2 points (range, 20-100 points), and over 60% of the evaluated patients showed good integration of the implant at 10 years postoperatively. CONCLUSIONS The clinical and radiologic findings of this study show that third-generation ACI is a suitable and effective option in the treatment of full-thickness cartilage defects of the knee. At 10 years after surgery, third-generation ACI shows stable results and leads to significant improvement in all clinical outcome parameters. Despite these results, revision surgery after third-generation ACI is common and was needed in 23% of patients in this study. LEVEL OF EVIDENCE Level IV, therapeutic case series.

Abstract
BACKGROUND Osteochondral defects (OCDs) of the talus are found subsequent to ankle sprains and ankle fractures. With many surgical treatment strategies available, there is no clear evidence on return-to-sport (RTS) times and rates. PURPOSE To summarize RTS times and rates for talar OCDs treated by different surgical techniques. STUDY DESIGN Systematic review; Level of evidence, 4. METHODS The literature from January 1996 to November 2018 was screened, and identified studies were divided into 7 different surgical treatment groups. The RTS rate, with and without associated levels of activity, and the mean time to RTS were calculated per study. When methodologically possible, a simplified pooling method was used to combine studies within 1 treatment group. Study bias was assessed using the MINORS (Methodological Index for Non-Randomized Studies) scoring system. RESULTS A total of 61 studies including 2347 talar OCDs were included. The methodological quality of the studies was poor. There were 10 retrospective case series (RCSs) that investigated bone marrow stimulation in 339 patients, with a pooled mean rate of RTS at any level of 88% (95% CI, 84%-91%); 2 RCSs investigating internal fixation in 47 patients found a pooled RTS rate of 97% (95% CI, 85%-99%), 5 RCSs in which autograft transplantation was performed in 194 patients found a pooled RTS rate of 90% (95% CI, 86%-94%), and 3 prospective case series on autologous chondrocyte implantation in 39 patients found a pooled RTS rate of 87% (95% CI, 73%-94%). The rate of return to preinjury level of sports was 79% (95% CI, 70%-85%) for 120 patients after bone marrow stimulation, 72% (95% CI, 60%-83%) for 67 patients after autograft transplantation, and 69% (95% CI, 54%-81%) for 39 patients after autologous chondrocyte implantation. The mean time to RTS ranged from 13 to 26 weeks, although no pooling was possible for this outcome measure. CONCLUSION Different surgical treatment options for talar OCDs allow for adequate RTS times and rates. RTS rates decreased when considering patients' return to preinjury levels versus return at any level.
