Abstract
INTRODUCTION Osteochondral lesions of the talus (OLT) usually have non-specific clinical symptoms, and radiographs have a low sensitivity for detecting OLT. The purpose of this study is to compare the diagnostic value of CT arthrography (CTa) with that of MRI using arthroscopy as the reference standard for grading OLT. MATERIALS AND METHODS We retrospectively reviewed patients who had OLT between 2015 and 2020. Patients with symptomatic OLT as a surgical indication, who were treated arthroscopically, and underwent both CTa and MRI before surgery were included. OLT was evaluated by both CTa and MRI using arthroscopy as the standard. We graded CTa, MRI, arthroscopic findings using Mintz classification. RESULTS Thirty-five patients were included. Accuracy rates of MRI and CTa for grading OLT, compared to those of arthroscopy, were 57.1% and 88.6%, respectively. Among 15 mismatched cases in MRI, 12 lesions (80%) were matched in CTa and arthroscopy. CTa had significantly higher diagnostic performance than MRI for the detection of grade III lesions (p = 0.041). Using the receiver operating characteristics curves, the area under the curve values for lesion grading were 0.893 for CTa and 0.762 for MRI. CONCLUSION CTa was statistically significantly better in detecting chondral flapping or subchondral exposure lesions for OLT than MRI on using arthroscopy as the reference standard. Because the stability of the OLT is essential in determining the treatment method, if an OLT is observed on MRI and is suspected to cause ankle pain, we recommend additional CTa examination to determine the more correct treatment strategies for OLT. LEVEL OF EVIDENCE Diagnostic Level III.

Abstract
PURPOSE To describe a new surgical technique for osteochondral lesions of the ankle, using bone marrow concentrate on a scaffold and homologous bone graft positioned through a retrograde approach. Many surgical options for ankle osteochondral lesions have been described, and the ideal treatment is still debated. Bone marrow stimulating techniques are recommended for cystic lesions, with some concerns regarding the healing potential of the subchondral bone. In case of wide osteochondral defects, regenerative solutions are preferred but a massive chondral debridement is usually required. To overcome these problems, a novel technique is proposed. METHODS The proposed technique was performed on patients affected by osteochondral lesions of the talus, either cysts with intact cartilage or wide osteochondral defects. A preoperative magnetic resonance imaging was obtained to localize the lesion. A 6-mm tarsal tunnel was retrogradely created toward the lesion, to allow a complete sub-endo-chondral debridement preserving the healthy cartilage. A hyaluronan scaffold soaked with a previously prepared bone marrow concentrate was retrogradely positioned under the cartilage surface and the tunnel was filled with homologous bone graft. Preoperative clinical scores and postoperative x-rays were registered. RESULTS Four patients were treated using this technique. No intraoperative and postoperative complications occurred. Good bone remodeling was observed at 12-week postoperative x-rays. CONCLUSIONS This technique combines the mini-invasiveness of retrograde drilling with the regenerative properties of biological scaffold soaked with bone marrow concentrate. Despite further research being needed, it seems a new viable solution to treat both subchondral cysts and large osteochondral defects of the ankle, whose management is still controversial.

Abstract
The treatment of subchondral lesions is an area with limited focus within the foot and ankle literature. The literature has shown an association between disruption of the subchondral bone plate and the formation of subchondral cysts. The primary causes of subchondral lesions are acute trauma, repetitive microtrauma, as well as idiopathic means. Evaluation of these injuries should be done carefully and often requires advanced imaging including MRI and computed tomography. Treatment does vary depending on the presentation of the subchondral lesion with or without the presence of an osteochondral lesion.

Abstract
Background Single-step all-arthroscopic techniques have gained popularity recently in the treatment of osteochondral lesions of the talus (OLT). Concomitant subchondral bone defects led surgeons to add autologous bone grafting to the surgical procedures. Collagen scaffolds have been used widely for stabilization of the reconstruction and regeneration of the articular surface. Purpose To compare single-step all-arthroscopic treatment of OLT consisting of debridement, microfracture, autologous bone grafting, and application of fibrin sealant in 2 patient groups: with versus without collagen scaffold. Study Design Cohort study; Level of evidence, 3. Methods Included were 94 patients who underwent single-step all-arthroscopic treatment for OLT. Autologous bone grafting was applied to 48 patients (BG group), while autologous bone grafting plus collagen scaffold was applied to 46 patients (BG+S group). A fibrin sealant was applied to both groups. Clinical outcomes were assessed with the American Orthopaedic Foot & Ankle Society (AOFAS) score and the visual analog scale (VAS) for pain. Radiological outcomes were evaluated with the magnetic resonance observation of cartilage repair tissue score. The mean follow-up time was 69.3 ± 20.7 months. Results Patients in both groups showed statistically significant improvement in pre- to postoperative AOFAS and VAS scores (P < .001 for all), with no difference between groups in AOFAS and VAS score improvement. Complete healing with or without hypertrophy was achieved in 42 patients in the BG group (87.5%) and 38 patients in the BG+S group (82.6%). Conclusion The treatment of bone lesions in OLT may be the ultimate goal to obtain successful outcomes, in which case using a collagen scaffold besides grafting may not affect clinical and radiological outcomes.

Abstract
Background Reports detailing the rates of radiographic healing after treatment of talar osteochondritis dissecans (TOCD) remain scarce. There is also a paucity of data characterizing treatment outcomes and the risk factors associated with poor outcomes in children with TOCD. Purpose To identify factors associated with healing, assess treatment outcomes, and develop a clinically useful nomogram for predicting healing of TOCD in children. Study Design Case-control study; Level of evidence, 3. Methods This was a retrospective review of all patients ≤18 years of age with TOCD from a single pediatric institution over a 12-year period. Surgical treatment was left to the discretion of the treating surgeon based on standard treatment techniques. Medical records and radiographs were reviewed for patient and clinical data, lesion characteristics, and skeletal maturity. Radiographic healing was evaluated at the 1-year follow-up, and patients with complete versus incomplete healing were compared using multivariable logistic regression models to examine the predictive value of the variables. Results The authors analyzed 92 lesions in 74 patients (mean age, 13.1 ± 2.7 years [range, 7.1-18.0 years]; 61% female). Of these, 58 (63%) lesions were treated surgically (drilling, debridement, microfracture, bone grafting, or loose body removal), and the rest were treated nonoperatively. Complete radiographic healing was seen in 43 (47%) lesions. In bivariate analysis, patients with complete healing were younger (P = .006), were skeletally immature (P = .013), and had a lower body mass index (BMI; P < .001) versus those with incomplete healing. In a multivariate regression model, the factors that correlated significantly with the rate of complete healing were age at diagnosis, BMI, and initial surgical treatment. The lesion dimensions were not significantly associated with the likelihood of healing. A nomogram was developed using the independent variables that correlated significantly with the likelihood of complete radiographic healing. Conclusion Complete radiographic healing of TOCD lesions was more likely in younger patients with a lower BMI. The effect of initial surgical treatment on potential healing rate was greater in older patients with a higher BMI.

Abstract
Talus osteochondral lesions are a commonly underdiagnosed problem in young athletes. Talus osteochondral lesions surgical algorithm remains controversial. Current metrics suggest that conventional treatment of osteochondral lesions of the talus is promising; yet return to sport is poorly studied. Fifty-seven patients following talus osteochondral lesion surgical intervention were included in this study. About 63.1% were female with mean age 37.1 years, mean lesion size 10 × 12.5 mm, and mean follow-up 79.9 months postoperatively. Patients were divided into 4 groups by surgery performed: antegrade arthroscopic bone marrow stimulation, retrograde arthroscopic drilling, osteochondral autograft transfer, and allograft cartilage implantation. Outcome metrics include Visual Analog Scale for pain and function, Short Form-12, Foot and Ankle Disability Scale, Tegner, Marx activity scores, Naal Sports inventory, and patient satisfaction. Over 77% of patients were satisfied with surgical intervention. Each intervention significantly decreased pain and increased function, except retrograde drilling. All interventions trended toward decreased Tegner score; only antegrade drilling showed significant decrease. Based on Naal's sports inventory, 85.7% of surgically treated patients reported participating in sport activities, on average 3 times/week and 50.6 minutes/session. Traditionally, talus osteochondral lesions present a difficult problem that is marred by unsatisfactory nonoperative outcomes in typically active patients. As our surgical understanding has evolved, we've continued to improve on outcomes. Our patients demonstrated 77.2% overall satisfaction rate, a statistically significant improvement in pain and function, at an average follow-up of 79.9 months postoperatively, and a high rate of return to sport with little difference between surgical interventions.

Abstract
BACKGROUND Microfracture is the most common reparative surgery for osteochondral lesions of the talus (OLTs). While shown to be effective in short- to midterm outcomes, the fibrocartilage that microfracture produces is both biomechanically and biologically inferior to that of native hyaline cartilage and is susceptible to possible deterioration over time following repair. With orthobiologics being proposed to augment repair, there exists a clear gap in the study of long-term clinical outcomes of microfracture to determine if this added expense is necessary. METHODS A retrospective review of patients undergoing microfracture of an OLT with a single fellowship-trained orthopedic surgeon from 2007 to 2009 was performed. Patients meeting the inclusion criteria were contacted to complete the Foot and Ankle Ability Measure (FAAM) Activities of Daily Living (ADL) and Sports subscales and visual analog scale (VAS) for pain, as well as surveyed regarding their satisfaction with the outcome of the procedure and their likelihood to recommend the procedure to a friend with the same problem using 5-point Likert scales. Patient demographics were reviewed and included for statistical analysis. RESULTS Of 45 respondents, 3 patients required additional surgery on their ankle for the osteochondral defect, yielding a 10-year survival rate of 93.3%. Of surviving cases, 90.4% (38/42) reported being "extremely satisfied" or "satisfied" with the outcome of the procedure. The VAS score at follow-up averaged 14 out of 100 (range, 0-75), while the FAAM-ADL and FAAM-Sports scores averaged 90.29 out of 100 and 82 out of 100, respectively. Thirty-six patients (85.7%) stated that their ankle did not prevent them from participating in the sports of their choice. CONCLUSION The current study represents a minimum 10-year follow-up of patients undergoing isolated arthroscopic microfracture for talar osteochondral defects, with a 93.3% survival rate and 85.7% return to sport. While biological adjuvants may play a role in improving the long-term outcomes of microfracture procedures, larger and longer-term follow-up studies are required for procedures using orthobiologics before their cost can be justified for routine use. LEVEL OF EVIDENCE Level IV, retrospective cohort case series study.

Abstract
Background: Retrograde drilling (RD) is generally used for treating osteochondral lesion of the talus (OLT) with a stable osteochondral fragment and nearly normal articular cartilage surface. Previous studies that included participants of various ages have reported good clinical results. This study aimed to clarify the clinical outcomes of RD for OLT in juvenile patients whose bone-forming ability and physical activity might affect the healing process. Methods: This retrospective study included 8 juvenile patients who underwent RD for OLT (5 boys and 3 girls, mean age 14.9 years, mean follow-up 2 years, 7 medial and 1 central lesion). American Orthopaedic Foot & Ankle Society (AOFAS) ankle-hindfoot score and ankle activity score were evaluated, and arthroscopic findings were graded according to the International Cartilage Research Society (ICRS) classification system. The condition of the underlying bone was assessed on preoperative computed tomographic images. The stability, incorporation, and subsidence of the osteochondral fragment, articular surface congruity, and the area of the bone marrow lesion (BML) were evaluated using magnetic resonance imaging (MRI). Results: AOFAS ankle-hindfoot score and ankle activity score significantly improved postoperatively. Arthroscopically, the lesions were classified as ICRS grade 0 or 1. Bone sclerosis or multiple small cysts of the underlying bone were observed in all patients. MRI demonstrated no signs of osteochondral fragment instability or subsidence, good or fair fragment incorporation, good articular surface congruity, or slight irregularity. The postoperative BML was reduced; however, these BMLs were still detectable at 1 year after surgery. Conclusion: Our data suggested that RD is an option for treating juvenile patients with OLT refractory to nonoperative treatment at short-term follow-up. Although bone sclerosis or multiple small cysts were identified in the underlying bone preoperatively and the BML under the osteochondral fragment remained postoperatively, clinical status such as pain and physical activity level were improved by RD. Level of Evidence: Level IV, retrospective case series.

Abstract
Autologous chondrocyte implantation (ACI) is a first-line treatment option for large articular cartilage defects. Although well-established for cartilage defects in the knee, studies of the long-term outcomes of matrix-assisted ACI to treat cartilage defects in the ankle are rare. In the present report, we describe for the first time the long-term clinical and radiologic results 12 years after polymer-based matrix-assisted ACI treat a full-thickness talar cartilage defect in a 25-year-old male patient. The clinical outcome was assessed using the visual analog scale and Freiburg ankle score, magnetic resonance imaging evaluation using the Henderson-Kreuz scoring system and T2 mapping. Clinical assessment revealed improved visual analog scale and Freiburg ankle scores. The radiologic analysis and T2 relaxation time values indicated the formation of hyaline-like repair tissue. Polymer-based autologous chondrocytes has been shown to be a safe and clinically effective long-term treatment of articular cartilage defects in the talus.

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

Diagnostic Value of CT Arthrography for Evaluation of Osteochondral Lesions at the Ankle. BIOMED RESEARCH INTERNATIONAL 2016; 2016:3594253. [PMID: 27891511 PMCID: PMC5116491 DOI: 10.1155/2016/3594253] [Citation(s) in RCA: 27] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/30/2016] [Accepted: 10/18/2016] [Indexed: 11/18/2022]
Abstract
Background. To retrospectively determine the diagnostic value of computed tomography arthrography (CTA) of the ankle in the evaluation of (osteo)chondral lesions in comparison to conventional magnetic resonance imaging (MRI) and intraoperative findings. Methods. A total of N = 79 patients had CTAs and MRI of the ankle; in 17/79 cases surgical reports with statements on cartilage integrity were available. Cartilage lesions and bony defects at talus and tibia were scored according to defect depth and size by two radiologists. Statistical analysis included sensitivity analyses and Cohen's kappa calculations. Results. On CTA, 41/79 and 31/79 patients had full thickness cartilage defects at the talus and at the tibia, respectively. MRI was able to detect 54% of these defects. For the detection of full thickness cartilage lesions, interobserver agreement was substantial (0.72 ± 0.05) for CTA and moderate (0.55 ± 0.07) for MRI. In surgical reports, 88–92% and 46–62% of full thickness defects detected by CTA and MRI were described. CTA findings changed the further clinical management in 15.4% of cases. Conclusions. As compared to conventional MRI, CTA improves detection and visualization of cartilage defects at the ankle and is a relevant tool for treatment decisions in unclear cases.

Comparison of clinical outcomes between arthroscopic subchondral drilling and microfracture for osteochondral lesions of the talus. Knee Surg Sports Traumatol Arthrosc 2016; 24:2140-7. [PMID: 25649727 DOI: 10.1007/s00167-015-3511-1] [Citation(s) in RCA: 40] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/29/2014] [Accepted: 01/12/2015] [Indexed: 01/25/2023]
Abstract
PURPOSE The objectives of this study were to compare the clinical outcomes of the two common bone marrow stimulation techniques such as subchondral drilling and microfracture for symptomatic osteochondral lesions of the talus and to evaluate prognostic factors affecting the outcomes. METHODS Ninety patients (90 ankles) who underwent arthroscopic bone marrow stimulation for small- to mid-sized osteochondral lesions of the talus constituted the study cohort. The 90 ankles were divided into two groups: a drilling group (40 ankles) and a microfracture group (50 ankles). Each group was matched for age and gender, and both groups had characteristics similar to those obtained from pre-operative demographic data. The American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score and the ankle activity score (AAS) were used to compare clinical outcomes, during a mean follow-up period of 43 months. RESULTS The median AOFAS scores were 66.0 points (51-80) in drilling group and 66.5 points (45-81) in microfracture group pre-operatively, and these improved to 89.4 points (77-100) and 90.1 points (69-100) at the final follow-up, respectively. The median VAS scores improved at the final follow-up compared with the pre-operative condition. The median AAS for the drilling group improved from 4.5 (1-6) pre-operatively to 6.0 (1-8) at the final follow-up, while those for the microfracture group improved from 3.0 (2-8) to 6.0 (3-9). No significant differences were observed between the two groups in terms of the AOFAS scores, VAS, and AAS. CONCLUSIONS The arthroscopic subchondral drilling and microfracture techniques that were used to stimulate bone marrow showed similar clinical outcomes. The results of this study suggest that both techniques are effective and reliable in treating small- to mid-sized osteochondral lesions of the talus, regardless of which of the two techniques is used. LEVEL OF EVIDENCE Level III, retrospective comparative study.

Abstract
BACKGROUND The radiographic appearance of osteochondritis dissecans (OCD) of the humeral capitellum varies according to the stage of the lesion. It is important to evaluate the stage of OCD lesion carefully to guide treatment. We compared the interobserver reliability of currently used classification systems for OCD of the humeral capitellum to identify the most reliable classification system. METHODS Thirty-two musculoskeletal radiologists and orthopaedic surgeons specialized in elbow surgery from several countries evaluated anteroposterior and lateral radiographs and corresponding computed tomography (CT) scans of 22 patients to classify the stage of OCD of the humeral capitellum according to the classification systems developed by (1) Minami, (2) Berndt and Harty, (3) Ferkel and Sgaglione, and (4) Anderson on a Web-based study platform including a Digital Imaging and Communications in Medicine viewer. Magnetic resonance imaging was not evaluated as part of this study. We measured agreement among observers using the Siegel and Castellan multirater κ. RESULTS All OCD classification systems, except for Berndt and Harty, which had poor agreement among observers (κ = 0.20), had fair interobserver agreement: κ was 0.27 for the Minami, 0.23 for Anderson, and 0.22 for Ferkel and Sgaglione classifications. The Minami Classification was significantly more reliable than the other classifications (P < .001). CONCLUSIONS The Minami Classification was the most reliable for classifying different stages of OCD of the humeral capitellum. However, it is unclear whether radiographic evidence of OCD of the humeral capitellum, as categorized by the Minami Classification, guides treatment in clinical practice as a result of this fair agreement.

Abstract
BACKGROUND Although various treatment modalities for an osteochondral lesion of the talus (OLT) with a subchondral cyst have been recommended previously, the primary treatment methods for such conditions have yet to be conclusively determined. Moreover, few comprehensive studies have compared the outcomes of cases where patients were treated with microfracture for OLT with and without subchondral cysts. PURPOSE To evaluate the clinical outcomes after arthroscopic microfractures performed as a primary treatment for OLT with a subchondral cyst. STUDY DESIGN Cohort study; Level of evidence, 2. METHODS The study cohort consisted of 102 patients (102 ankles) who underwent arthroscopic microfracture for small to midsized OLT. The ankles were divided into a cyst group (45 ankles) and a noncyst group (57 ankles).The American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot scale, visual analog scale (VAS), and Ankle Activity Score (AAS) were used to compare the clinical outcomes between the groups over a mean follow-up period of 48 months. RESULTS The mean AOFAS ankle-hindfoot scores were 64.8 in the cyst group and 66.2 in the noncyst group preoperatively. These improved to 91.8 and 91.3, respectively, at the final follow-up. The mean VAS scores were 7.5 in the cyst group and 7.3 in the noncyst group preoperatively; these improved to 2.3 and 2.2, respectively, at the final follow-up. The mean AAS in the cyst group and the noncyst group improved from 2.7 and 2.6 preoperatively to 6.7 and 6.5 at the final follow-up, respectively. In terms of radiographic stage improvements, the cyst group showed no change in 18 ankles (40%) and showed improvements of 1 grade in 13 ankles (28.9%), 2 grades in 9 ankles (20%), 3 grades in 3 ankles (6.7%), and 4 grades in 2 ankles (4.4%). The noncyst group showed no change in 17 ankles (29.8%) and showed improvements of 1 grade in 11 ankles (19.3%), 2 grades in 11 ankles (19.3%), 3 grades in 14 ankles (24.6%), and 4 grades in 4 ankles (7.0%). No significant differences were found between the groups in terms of the AOFAS score, VAS score, AAS, or radiographic stage improvements. CONCLUSION OLT with and without subchondral cysts treated with arthroscopic microfracture showed similarly good clinical results. The study results suggest that microfracture could be a primary treatment strategy for treating small to midsized OLT regardless of the existence of subchondral cysts.

Abstract
BACKGROUND Marrow stimulation for the treatment of osteochondral lesions of the talus (OLTs) is controversial in patients with poor prognostic factors of OLTs. Currently, mesenchymal stem cells (MSCs) are expected to biologically augment the treatment of OLTs. PURPOSE To compare the clinical and magnetic resonance imaging (MRI) outcomes between an injection of MSCs with marrow stimulation and marrow stimulation alone in patients with OLTs. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS A total of 49 patients (50 ankles) with OLTs underwent follow-up MRI after arthroscopic treatment. Among these 50 ankles, 26 underwent marrow stimulation alone (conventional group), and 24 underwent marrow stimulation with an injection of a stromal vascular fraction (SVF) containing MSCs (MSC group). Clinical outcomes were evaluated according to the visual analog scale (VAS) for pain, American Orthopaedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot Scale, and Tegner activity scale. The magnetic resonance observation of cartilage repair tissue (MOCART) score was used for the MRI evaluation of repaired lesions. RESULTS The mean VAS score, AOFAS score, and Tegner score improved from 7.1 ± 1.2, 68.5 ± 5.6, and 3.4 ± 0.6 to 3.9 ± 0.8, 78.3 ± 4.9, and 3.5 ± 0.8, respectively, in the conventional group and from 7.1 ± 0.8, 67.7 ± 4.7, and 3.4 ± 0.5 to 3.2 ± 0.8, 83.3 ± 7.0, and 3.9 ± 0.7, respectively, in the MSC group. All clinical outcomes, including the VAS, AOFAS, and Tegner scores, improved significantly in the MSC group compared with the conventional group (P = .003, .009, and .041, respectively). There was a significant difference (P = .037) in the mean MOCART score between the conventional and MSC groups (49.4 ± 16.6 vs 62.1 ± 21.8, respectively), and significant correlations of the MOCART score with clinical outcomes were found in both groups (P < .05). Patient age (≥46.1 years), large lesion size (≥151.2 mm(2)), and the presence of subchondral cysts were associated with a worse MOCART score in the conventional group (P = .015, .004, and .013, respectively) but not in the MSC group. CONCLUSION Clinical and MRI outcomes of an injection of an SVF containing MSCs with marrow stimulation were encouraging, compared with marrow stimulation alone, for the treatment of OLTs. Therefore, an injection of an SVF containing MSCs with marrow stimulation should be considered as a treatment for OLTs, even when poor prognostic factors, including older age, large-sized lesion, or the presence of subchondral cysts, exist.

Abstract
BACKGROUND Autologous osteochondral transplantation (AOT) is used for large (>100-150 mm(2)) or cystic osteochondral lesions (OCLs) of the talus. Larger lesions may require using more than 1 graft to fill the defect. While patients with larger OCLs treated with microfracture exhibit inferior clinical outcomes, there is little evidence regarding the effect of lesion size and number of grafts required on clinical and radiological outcomes after AOT. HYPOTHESIS Larger OCLs of the talar dome treated by double-plug AOT (dp-AOT) have inferior clinical and radiological MRI outcomes compared with smaller OCLs requiring single-plug AOT (sp-AOT). STUDY DESIGN Cohort study; Level of evidence, 3. METHODS Fourteen consecutive patients with a large OCL (mean, 208 ± 54 mm(2)) treated using dp-AOT with a minimum 5-year follow-up were matched by age and sex to a control cohort of 28 patients who underwent sp-AOT for a smaller OCL (mean, 74 ± 26 mm(2)) over the same period. Functional outcomes were assessed both pre- and postoperatively using the Foot and Ankle Outcome Score (FAOS) and Short Form-12 (SF-12) general health questionnaire. Mean follow-up was 85 months (range, 65-118 months). Latest postoperative MRI was evaluated with modified magnetic resonance observation of cartilage repair tissue (MOCART) score. RESULTS There was no significant difference between groups demographically (P > .05). All patients with dp-AOT and sp-AOT showed a significant pre- to postoperative increase in FAOS and SF-12 scores (P < .001). When comparing preoperative scores for both groups, there was no statistical significance between sp-AOT and dp-AOT scores (FAOS, P = .719; SF-12, P = .947). There was no significant difference in functional scores between the 2 groups postoperatively for both FAOS (P = .883) and SF-12 (P = .246). Mean MOCART scores did not exhibit any statistically significant difference between groups (P = .475). Two patients complained of knee donor site stiffness (4.8%), which later resolved. CONCLUSION Patients with large OCLs treated using a dp-AOT procedure did not show inferior clinical or radiological outcomes compared with those treated with sp-AOT at a minimum 5-year follow-up. The dp-AOT procedure is as effective as sp-AOT in treating larger OCLs of the talar dome in the intermediate term, with similar high postoperative clinical and radiological outcomes.

Abstract
Osteochondral lesions (OCLs) occur in up to 70% of sprains and fractures involving the ankle. Atraumatic aetiologies have also been described. Techniques such as microfracture, and replacement strategies such as autologous osteochondral transplantation, or autologous chondrocyte implantation are the major forms of surgical treatment. Current literature suggests that microfracture is indicated for lesions up to 15 mm in diameter, with replacement strategies indicated for larger or cystic lesions. Short- and medium-term results have been reported, where concerns over potential deterioration of fibrocartilage leads to a need for long-term evaluation. Biological augmentation may also be used in the treatment of OCLs, as they potentially enhance the biological environment for a natural healing response. Further research is required to establish the critical size of defect, beyond which replacement strategies should be used, as well as the most appropriate use of biological augmentation. This paper reviews the current evidence for surgical management and use of biological adjuncts for treatment of osteochondral lesions of the talus.

Abstract
BACKGROUND The ankle joint can be affected by several diseases, with clinical presentation varying from mild pain or swelling to inability, becoming in some cases a serious problem in daily life activities. Arthroscopy is a widely performed procedure in orthopedic surgery, due to the low invasivity compared to the more traditional open field surgery. The ankle joint presents anatomical specificities, like small space and tangential view that make arthroscopy more difficult. METHODS From 2000 more than 600 ankle arthroscopies were performed at our institution. The treated pathologies were mostly impingement syndrome and osteochondral lesions, and in lower percentage instabilities and ankle fractures. RESULTS In the impingement, the AOFAS scores at FU showed an increase compared to scores collected preoperatively, with improvement of symptoms in most of the cases, good or excellent results in 80 % of cases. In ligament injuries, AOFAS score significatively improved at the maximum follow-up. In fractures all patients had an excellent AOFAS score at maximum follow-up, with complete return to their pre-injury activities. In osteochondral injuries, the clinical results showed a progressive improvement over time with the different performed procedures. Control MRI and bioptic samples showed a good regeneration of the cartilage and bone tissue in the lesion site. CONCLUSIONS The encouraging obtained clinical results, in line with the literature, show how the arthroscopic technique, after an adequate learning curve, may represent a precious aid for the orthopedic surgeon and for the patient's outcome.

Abstract
Osteochondritis dissecans of the talus (ODT) describes a special entity of osteochondral lesions of the talus (OLT) which has to be distinguished from acute traumatic lesions. Its exact etiology still remains uncertain with multiple predispositioning factors being discussed. Following the knee and elbow, the ankle joint with 4% is the third most affected joint. Early stages can often be treated conservatively. In case of an advanced stage or failure of conservative treatment, a variety of operative techniques are available, which can be used based on the patient and the stage.

Abstract
The surgical management of young patients with large osteochondral lesions of the talus or end-stage osteoarthritis of the ankle joint presents a challenge to the orthopedic surgeon because these are well-recognized sources of pain and dysfunction. Procedures designed to address these disorders either have a limited role because of poor success rates or have significant implications, such as with the total ankle arthroplasty. Fresh osteochondral allografts allow defective tissue to be anatomically matched and reconstructed through transplantation. This article presents an overview of fresh osteochondral allografts, as well as potential concerns with their use, and summarizes the current literature.

Abstract
➤ Osteochondral lesions of the talus are common injuries in recreational and professional athletes, with up to 50% of acute ankle sprains and fractures developing some form of chondral injury. Surgical treatment paradigms aim to restore the articular surface with a repair tissue similar to native cartilage and to provide long-term symptomatic relief.➤ Arthroscopic bone-marrow stimulation techniques, such as microfracture and drilling, perforate the subchondral plate with multiple openings to recruit mesenchymal stem cells from the underlying bone marrow to stimulate the differentiation of fibrocartilaginous repair tissue in the defect site. The ability of fibrocartilage to withstand mechanical loading and protect the subchondral bone over time is a concern.➤ Autologous osteochondral transplantation techniques replace the defect with a tubular unit of viable hyaline cartilage and bone from a donor site in the ipsilateral knee. In rare cases, a graft can also be harvested from the ipsilateral talus or contralateral knee. The limitations of donor site morbidity and the potential need for an osteotomy about the ankle should be considered. Some anterior or far posterior talar lesions can be accessed without arthrotomy or with a plafondplasty.➤ Osteochondral allograft transplantation allows an osteochondral lesion with a large surface area to be replaced with a single unit of viable articular cartilage and subchondral bone from a donor that is matched to size, shape, and surface curvature. The best available evidence suggests that this procedure should be limited to large-volume cystic lesions or salvage procedures.➤ Autologous chondrocyte implantation techniques require a two-stage procedure, the first for chondrocyte harvest and the second for implantation in a periosteum-covered or matrix-induced form after in vivo culture expansion. Theoretically, the transplantation of chondrocyte-like cells into the defect will result in hyaline-like repair tissue.

Abstract
PURPOSE The purpose of this study was to systematically review studies on autologous osteochondral transplantation (AOT) for osteochondral lesions (OCLs) of the talus and descriptively analyze the outcome data reported to determine whether it is consistent from one study to another and able to be pooled for systematic review. METHODS A systematic electronic search was performed using the MEDLINE and EMBASE databases. Studies that were published between January 1966 and June 2011 were included in the review. Only studies that reported data specifically on AOT for treatment of OCLs of the talus and written in English were included in this review. A predefined data sheet with 36 variables was created, and it was determined whether or not each of those variables were reported or not reported. The 36 variables were then grouped into 6 categories, and the categorical means were reported. RESULTS A total of 20 studies were included in this systematic review. The categories of general demographics and study design were generally well reported (each more than 80% of studies). Patient-reported outcomes and clinical variables were reported less in 73% and 67% of studies, respectively. The least-reported categories were patient history (45%) and imaging data (49%). CONCLUSIONS Inconsistencies and an underreporting of data were apparent between studies, such that pooling was deemed not possible. An effort must be made by investigators to ensure that there is adequate reporting of data in studies of AOT treatment for OCLs of the talus.

Abstract
BACKGROUND Microfracture is recognized as a primary treatment strategy for osteochondral lesions of the talus up to 15 mm in size. The ability of fibrocartilage to withstand the mechanical loading of the joint over time is unknown. PURPOSE The purpose of this study was to systematically review studies of microfracture for OLT and descriptively analyze the outcome data reported to determine whether it is consistent from one study to another and able to be pooled for systematic review. METHODS A systematic electronic search was performed using the MEDLINE and EMBASE databases. Studies that were published between January 1966 and June 2011 were included in the review. Only studies that reported data specifically on microfracture for treatment of osteochondral lesions of the talus and written in English were included in this review. RESULTS Twenty-four studies were included in this systematic review. The categories of general demographics and study design were generally well reported (each over 80% of studies). Patient history and patient-reported outcome data were reported less (55%-66%). Clinical variables (48%) and imaging data (39%) were the least reported in studies. CONCLUSION There were gross inconsistencies and an underreporting of data between studies such that pooling was deemed impossible. A concerted effort must be made by investigators to ensure that there is adequate reporting of data in studies of microfracture treatment for OLT. A set of guidelines to assist surgeons in reporting data may be useful for future research.

Abstract
Recurrent ankle sprains and other trauma as well as ankle malalignment can lead to chronic osteochondral lesions of the talus. Conservative treatment frequently fails. Several operative treatment techniques exist; however, the choice of the right procedure is difficult. This article presents a new surgical technique suitable for treatment osteochondral lesions that combines bone plasty and a collagen matrix.

Abstract
BACKGROUND Osteochondral lesions (OCLs) of the talus are a common entity in sports orthopaedics. There are several operative techniques with a good outcome on follow-up examinations. However, limitations such as sacrificing healthy cartilage (osteochondral autograft transfer system [OATS], mosaicplasty), multiple-stage operative procedures (matrix-induced autologous chondrocyte transplantation [MACI], autologous chondrocyte implantation [ACI]), high costs (ACI, allograft), and limited availability (allograft) do remain and reflect potential drawbacks of the currently used techniques. PURPOSE To describe a novel operative technique for the treatment of OCLs of the talus in the form of an economically efficient, 1-step procedure combining OCL debridement, spongiosaplasty, and sealing of the OCL area with a collagen matrix. STUDY DESIGN Case series; Level of evidence, 4. METHODS Twenty-six patients underwent surgery receiving a modified autologous matrix-induced chondrogenesis (AMIC)-aided repair of OCLs of the talus consisting of debridement, autologous grafting, and sealing of the defect with a collagen scaffold. Ligament repair was performed in 17 of 26 cases. A corrective calcaneal osteotomy was performed in 16 of 26 cases. Clinical and radiological assessment was performed before and a minimum of 24 months after surgery (mean, 31 months; range, 24-54 months). Clinical examination included the American Orthopaedic Foot and Ankle Society (AOFAS) ankle score and the visual analog scale (VAS) for pain. Radiological imaging included single-photon emission computed tomography-computed tomography (SPECT-CT) and magnetic resonance imaging (MRI). The magnetic resonance observation of cartilage repair tissue (MOCART) score was applied, and sport activity was documented. RESULTS The AOFAS ankle score improved significantly from a mean of 60 points preoperatively (range, 17-79 points) to 89 points (range, 61-100 points) postoperatively (P < .01). The preoperative pain score averaged 5 (range, 2-8), improving to an average of 1.6 (range, 0-7) postoperatively (P < .01). The MOCART score for cartilage repair tissue on postoperative MRI averaged 62 points (range, 20-95 points). Complete filling of the defect at the level of the surrounding cartilage was found in 35%, and complete filling with a hypertrophic cartilage layer was found in 50% of the patients. Normal signal intensity of the repair tissue compared with the adjacent native cartilage was seen in 15%, with nearly normal activity in 69%. Nineteen patients (73%) participated in sports before the onset of symptoms compared with 3 (12%) at the time of surgery. The number increased to 16 patients (62%) at postoperative follow-up. CONCLUSION The modified AMIC procedure is safe for the treatment of OCLs in the ankle with overall good clinical and MRI results.

Abstract
BACKGROUND Landmine injuries cause extensive soft and bony tissue loss of the weight-bearing areas, particularly the heel. Reconstruction of these injuries is challenging, and there are no studies that report long-term functional results. OBJECTIVE To determine the quality of life and long-term functionality of patients who had heel reconstruction with free muscle flap after landmine injuries. DESIGN A case-control study. PARTICIPANTS Nine male patients who had heel reconstruction with free muscle flap. Ten male volunteers without any gait disorder were included in the study as the control group. METHODS AND INTERVENTIONS Functional ambulation scale, visual analog scale, energy expenditure index, 6-minute walking test, 10-m walking test, and Short Form 36 were performed to determine the quality of life and functionality of the participants. RESULTS There were no statistically significant differences between the 2 groups in terms of functional ambulation scale, energy expenditure index, 6-minute walking test, and 10-m walking test. Regarding Short Form 36 scores, all subgroup values were lower in the reconstruction group, whereas only those of general health, vitality, and physical-emotional role limitation subgroups showed statistical significance. Mean visual analog scale scores were found to be statistically different between the groups (P < .05). Mean Freiburg Ankle scores showed moderate functionality. CONCLUSION Despite the associated physical and emotional trauma, combat-injured veterans with heel reconstruction after landmine injuries had adequate and functional ambulation at long-term follow-up. Early rehabilitation and close cooperation between surgeons and rehabilitation physicians during the care of these patients will enhance patient outcomes.

Abstract
PURPOSE Arthroscopic microfracture (AM) of osteochondral lesions of the talus is used to induce intrinsic refilling of the defect and reduce pain. The aim of this retrospective study was to investigate the clinical state after AM and the MRI outcome. METHODS A total of 22 patients [10 women, 12 men, 31 years old (mean, 13-68 range)] treated for osteochondral lesions of the talus by AM were examined 2 years (median) postoperatively and pre- and postoperative MRI results compared. Swelling/effusion, articular constriction, joint pain, and range of motion restriction were documented. Clinical state was evaluated using the AOFAS hindfoot score. MRI was used to assess the size of the defect, presence of bone marrow edema, cysts and effusion, thickness of repair tissue, and integrity of the cartilage. RESULTS In all but six cases, the defect was located at the medial shoulder of the talus. The postoperative AOFAS score at follow-up was 87.5 points (median 36-100 points range). Seven patients were free of pain, 11 had "mild, occasional" pain, 1 "moderate daily", and 3 "severe, almost always present" pain (AOFAS). The defect volume was significantly reduced from 377 mm(3) preoperatively (median, interquartile distance: 417 mm(3)) to 249 mm(3) postoperatively (median, IQD: 336 mm(3), p = 0.019, Wilcoxon). In 7 cases, the defect was completely filled, in 11 partially and in 4 only slightly. CONCLUSION After AM of osteochondral lesions of the talus, 18 of 22 patients had no or mild, occasional pain at 2 years follow-up. On MRI, the lesion volume had been reduced and filling with repair tissue was found.

Abstract
Talar dome lesions (TDL) have increasingly been the focus of interest of many foot and ankle surgeons over the past decade. The most important treatment aspect of TDL is diagnosis, so that appropriate treatment protocols can be enacted in a timely and stepwise manner. Minor or mild TDL may be treated conservatively, while severe acute or chronic TDL can be addressed with various surgical interventions. By being aware of all practical treatment options and their indications, success rates, benefits, risks, and alternative options, specialists will be able to make an informed decision on appropriate care selection after perusing this article.

Abstract
PURPOSE Osteochondritis dissecans (OCD) is an aseptic bone necrosis and represents pathology of high clinical relevance, which is frequently located on the talus. Various treatment strategies including non-surgical and surgical approaches have been described. An evidence-based treatment algorithm is still lacking. The present systematic review focuses on surgical treatment options and their stage-dependent outcome described for treatment of osteochondritis dissecans of the talus with special regard to the best available evidence. METHODS For this purpose, an OVID-based systematic literature search was performed including the following databases; MEDLINE, MEDLINE preprints, EMBASE, CINAHL, Life Science Citations, British National Library of Health and Cochrane Central Register of Controlled trials (CENTRAL). Literature search period was from January 1967 up to December 2009. After applying study specific inclusion criteria (minimum follow-up 12 months, patient evaluation by standardized scoring systems, etc.), a total of 54 studies with clinical follow-up of 1,105 patients was included. Methodology of these studies was systematically analyzed by the means of the Coleman Methodology Score. Outcome and success rate was evaluated in dependence of surgical treatment applied and in dependence of the stage of disease. RESULTS All 54 studies included were classified as evidence level IV representing case series. The average Coleman Methodology Score was 63 (SD ± 17) points. The average follow-up of the 1,105 patients was 47 months (SD ± 17) with a mean age of 29 (SD ± 5.6) years. The proportion of excellent and good treatment results was stage-independent in total 75 %. According to the criteria of the score applied for patient's evaluation in the individual study, the overall percentage of "good" and "excellent" clinical outcome in 869 patients was 79 %, and according the classification of Berndt and Harty, 82 % in stage I, 86 % in stage II, 83 % in stage III and 76 % in stage IV. CONCLUSIONS Although OCD of the talus represents a frequently observed orthopedic pathology, evidence concerning operative treatment of osteochondrosis dissecans of the talus is still elusive. With over 1,100 included patients in the present study, no strong recommendations based upon scientific evidence can be given.

Abstract
PURPOSE To detect radiographically occult cartilage lesions using CT arthrography (CTa) in patients with malleolar fractures treated with open reduction internal fixation and to correlate the lesions with the functional outcome score. MATERIALS AND METHODS Twenty-one patients (13 men and 8 women, mean age 35 years, range 16-55) underwent ankle CTa after a mean postoperative period of 565 days (range 271-756). CTa images were analyzed by two radiologists. Articular surface post-traumatic collapse and subsequent cartilage defects or erosions were recorded in millimeters and in a binary mode (i.e., present if >50% of cartilage thickness) respectively. The functional outcome was assessed using the American Orthopedic Foot and Ankle Society (AOFAS) score by two orthopaedic surgeons. The statistical analysis correlated the AOFAS score with both imaging parameters and was performed with ANOVA using the MedCalc statistical package, version 11.3. RESULTS Of the total of 12 articular surface steps recorded, 2/12 (16.67%) were anterolateral, 4/12 (33.33%) posterolateral, 5/12 (41.67%) anteromedial, and 1/12(8.33%) posteromedial. Of the total of 42 cartilage lesions, 7/42 (16.67%) were anterolateral, 14/42 (33.33%) posterolateral, 12/42 (28.57%) anteromedial, and 9/42 (21.43%) posteromedial. The mean AOFAS score was 8.67 (range 5.95-9.70). There was no statistically significant correlation between the AOFAS score and the post-traumatic internal derangement of the ankle joint (p = 0.524). CONCLUSION CTa detects radiographically silent cartilage lesions in patients with fractures of the ankle joint. There is no correlation of the extent of lesions and the patient's AOFAS score.

Abstract
PURPOSE The aim of this study is to report the outcomes of the treatment of talar osteochondral lesions with arthroscopic microfracture technique and postoperative intra-articular hyaluronan injection. METHOD Fifty-seven patients (29 men, 28 women) with osteochondral lesions of the talus were included in this prospective randomized clinical study between the years 2003 and 2009. The patients were treated with arthroscopic debridement and microfracture technique. Randomly selected 41 patients were injected intra-articular hyaluronan (injection group). The remaining 16 patients did not receive postoperative injection (non-injection group). Assessment of the pain and functional outcomes was performed using the Freiburg and AOFAS ankle/hindfoot scoring systems. RESULTS In the injection group, the mean postoperative Freiburg functional and pain scores were significantly higher compared to preoperative functional and pain scores (P < 0.001). Similarly, for the patients in non-injection group, the mean postoperative Freiburg functional and pain scores were significantly higher compared to preoperative functional and pain scores (P < 0.001). The AOFAS functional and pain scores of the patients in the injection group were significantly higher (P < 0.001) postoperatively compared to preoperative scores. Scoring the patients in the non-injection group according to AOFAS system also revealed significantly higher (P < 0.001) postoperative functional and pain scores over preoperative scores. The increase in the postoperative scores was found to be significantly higher in the injection group compared to non-injection group in both Freiburg and AOFAS systems (P < 0.001). CONCLUSION Treatment of osteochondral lesions of the talus using microfracture technique significantly improved functional and pain scores postoperatively. Additional treatment with intra-articular hyaluronan injection as an adjunct to microfracture technique may offer better clinical outcomes over microfracture technique alone. LEVEL OF EVIDENCE Randomized, controlled trial, Level I.

Abstract
Objective: To present clinical experience on matrix-induced autologous chondrocyte implantation (MACI), we hereby reported treatment with MACI for 3 patients suffering from chondral lesion of the knee, each of them has been followed for a minimum of 10 months. Methods: Ages of 3 patients were 25, 15 and 32 years old respectively. And the cartilage defect size ranged from 6cm2-10.5cm2). IKDC2000 score was used for knee functional evaluation. Magnetic resonance imaging (MRI) and arthroscopy were performed preoperatively and postoperatively. A biopsy of the regenerated cartilage from one patient was histologically evaluated 15 months after MACI. Results: In the postoperative period, no associated complications were observed. Each patient showed improvements both in clinical and functional status after surgery. MRI and arthroscopy showed the presence of hyaline-like cartilage at the site of implantation. The cartilage biopsy on the first patient showed a high ratio of hyaline-like cartilage tissue to fibrocartilage tissue which was 2 to 1. Conclusion: The clinical outcome and histological evaluation suggest that MACI is able to relieve pain and restore the function of the knee, also is capable of regenerating hyaline cartilage. In conclusion, MACI appears a promising method for the treatment of chondral defects of the knee.

Abstract
BACKGROUND Autologous osteochondral transplantation procedures provide hyaline cartilage to the site of cartilage repair. It remains unknown whether these procedures restore native contact mechanics of the ankle joint. PURPOSE This study was undertaken to characterize the regional and local contact mechanics after autologous osteochondral transplantation of the talus. STUDY DESIGN Controlled laboratory study. METHODS Ten fresh-frozen cadaveric lower limb specimens were used for this study. Specimens were loaded using a 6 degrees of freedom robotic arm with 4.5 N·m of inversion and a 300-N axial compressive load in a neutral plantar/dorsiflexion. An osteochondral defect was created at the centromedial aspect of the talar dome and an autologous osteochondral graft from the ipsilateral knee was subsequently transplanted to the defect site. Regional contact mechanics were analyzed across the talar dome as a function of the defect and repair conditions and compared with those in the intact ankle. Local contact mechanics at the peripheral rim of the defect and at the graft site were also analyzed and compared with the intact condition. A 3-dimensional laser scanning system was used to determine the graft height differences relative to the native talus. RESULTS The creation of an osteochondral defect caused a significant decrease in force, mean pressure, and peak pressure on the medial region of the talus (P = .037). Implanting an osteochondral graft restored the force, mean pressure, and peak pressure on the medial region of the talus to intact levels (P = .05). The anterior portion of the graft carried less force, while mean and peak pressures were decreased relative to intact (P = .05). The mean difference in graft height relative to the surrounding host cartilage for the overall population was -0.2 ± 0.3 mm (range, -1.00 to 0.40 mm). Under these conditions, there was no correlation between height and pressure when the graft was sunken, flush, or proud. CONCLUSION/CLINICAL RELEVANCE Placement of the osteochondral graft in the most congruent position possible partially restored contact mechanics of the ankle joint. Persistent deficits in contact mechanics may be due to additional factors besides graft congruence, including structural differences in the donor cartilage when compared with the native tissue.

Abstract
BACKGROUND Osteochondral lesions of the talar dome can cause substantial functional impairment and present a difficult treatment dilemma. Interest has recently focused on fresh osteochondral allografts as a promising treatment alternative. The purpose of this study was to evaluate the clinical outcome of osteochondral lesions of the talus treated with a fresh osteochondral allograft. METHODS We performed a transfer of fresh osteochondral allograft in forty-two patients with a symptomatic, refractory osteochondral lesion of the talus. Complete postoperative follow-up was achieved for thirty-eight patients with an average age of 44.2 years. Clinical evaluation was performed with use of the American Orthopaedic Foot & Ankle Society ankle-hindfoot score and a visual analog pain scale. All scores were obtained from either a retrospective chart review or a direct patient interview. All patients were also asked about their subjective satisfaction with the procedure. Magnetic resonance images were acquired for fifteen patients, to assess graft incorporation, subsidence, articular cartilage congruity, osteoarthritis, and stability with use of the De Smet criteria. RESULTS The average duration of follow-up after osteochondral allograft transplantation was 37.7 months. Graft failure occurred in four patients. With the inclusion of scores before revision for those with graft failure, the mean visual analog pain scale score improved from 8.2 to 3.3 points, and the mean American Orthopaedic Foot & Ankle Society ankle-hindfoot score improved from 52 to 79 points. Patient satisfaction with the outcome was rated as excellent, very good, or good by twenty-eight of the thirty-eight patients and as fair or poor by ten patients. Of the fifteen magnetic resonance imaging scans, most showed minimal graft subsidence, reasonable graft stability, and persistent articular congruence. CONCLUSIONS In our experience, transplantation of fresh osteochondral allograft is a viable and effective method for the treatment of osteochondral lesions of the talus as evidenced by improvements in pain and function.

Abstract
Due to its high spatial resolution and excellent tissue contrast, magnetic resonance imaging (MRI) has become the most commonly used imaging method to evaluate joints. Most musculoskeletal MRI is performed using 2D fast spin-echo sequences. However, 3D sequences have also been used for joint imaging and have the advantage of acquiring thin continuous slices through joints, which reduces the effects of partial volume averaging. With recent advances in MR technology, 3D sequences with isotropic resolution have been developed. These sequences allow high-quality multiplanar reformat images to be obtained following a single acquisition, thereby eliminating the need to repeat sequences with identical tissue contrast in different planes. Preliminary results on the diagnostic performance of 3D isotropic resolution sequences are encouraging. However, additional studies are needed to determine whether these sequences can replace currently used 2D fast spin-echo sequences for providing comprehensive joint assessment in clinical practice.

Abstract
Magnetic resonance (MR) imaging is one of the most commonly used imaging modality for evaluating patients with joint pain. Musculoskeletal MR protocols at most institutions consist of 2-dimensional fast spin echo (FSE) sequences repeated in multiple planes. Three-dimensional sequences have also been used to evaluate the musculoskeletal system and have many potential advantages over 2-dimensional FSE sequences. Three-dimensional sequences acquire thin continuous slices through joints with high in-plane spatial resolution, which minimize the effects of partial volume averaging. Newly developed 3-dimensional isotropic resolution sequences can also be used to create high-quality multiplanar reformat images that allow joints to be evaluated in any orientation after a single acquisition. Preliminary results on the use of 3-dimensional isotropic resolution sequences for evaluating the musculoskeletal system are encouraging. However, additional studies are needed to document the advantages of 3-dimensional sequences before they can replace currently used 2-dimensional FSE sequences for evaluating the musculoskeletal system in clinical practice.

Abstract
Osteochondral lesions of the talus are common injuries following acute and chronic ankle sprains. Numerous surgical treatment strategies have been employed for treating these lesions; arthroscopic bone marrow stimulation is recognized as the first-line technique to provide fibrocartilage infill of the defect site. While the short- and medium-term outcomes of this technique are good, the long-term outcomes are not yet known. An increasing number of studies, however, show a cause for concern in employing this technique, including declining outcome scores over time. The current authors have therefore developed a treatment strategy based on previously established guidelines in addition to morphological cartilage-sensitive fast spin echo techniques and quantitative T2 mapping magnetic resonance imaging (MRI). Accordingly, the authors advocate arthroscopic bone marrow stimulation in lesion sizes up to 8 mm in diameter and osteochondral autograft transplant (OATS) in lesion sizes greater than 8 mm in diameter. In the absence of long-term studies, confining the use of arthroscopic bone marrow stimulation to smaller lesions may support prolonged joint life by decreasing the rate at which the fibrocartilage ultimately degenerates over time. Employing the OATS procedure in larger lesions has the advantage of replacing "like with like." The current review examines the role of arthroscopic bone marrow stimulation techniques of the talus.

Abstract
A review of outcomes in 13 patients with talar dome osteochondral or chondral lesions treated with a bone graft substitute plug was undertaken in an effort to evaluate its effectiveness in comparison with other reported surgical techniques. Mean patient age was 36.4 (range 16 to 57) years. Mean follow-up was 30.1 (range 7 to 43) months. Medial malleolar osteotomy was performed in 9 (69.23%) cases. Average defect diameter was 9.8 (range 5 to 20) mm. Pain decreased significantly from 6.2 (range 3 to 9) to 4.0 (range 0 to 9) (P = .009). Postoperative American Orthopaedic Foot and Ankle Society Ankle-Hindfoot scores averaged 67.3 (range 26 to 100). Younger age, smaller defect size, and avoidance of medial malleolar osteotomy resulted in better outcomes. Mean Short Form-36 scores for the study group fell below US norms in all categories, and 12 (92.31%) ankles demonstrated persistent lesions radiographically. Postoperative magnetic resonance imaging in 2 (15.39%) patients demonstrated enlarged lesions, and 4 (30.77%) patients underwent revision surgery that revealed abnormal cartilage around the implant site. Complications included 1 (7.69%) deep venous thrombosis, 1 (7.69%) arthrofibrosis, and 1 (7.69%) superficial neuritis. Despite some improvement in pain, comparison of functional outcome showed bone graft substitute plug implantation to be less effective overall than other operative interventions. Future investigations with more specific selection criteria are warranted to gain further insight into the efficacy of these bone graft substitute plugs.

Abstract
BACKGROUND The progress of diagnostic imaging technology, including CTs, MRIs, and ankle arthroscopy has encouraged more detailed descriptions of osteochondral lesions of the talus. These lesions can vary from chondral fragments separated from the subchondral bone with or without bone sclerosis or cysts in the subchondral layers. Isolated lesions of the cartilage, defined as chondral-separated types, as opposed to the osteochondral-separated types which were osteochondral fragments, were retrospectively evaluated in this study. MATERIALS AND METHODS Seventy-three osteochondral lesions of the talus in 69 patients were treated. There were 29 chondral-separated types in 29 patients confirmed by examining CT, MRI, and arthroscopic findings. RESULTS The average age at onset of the chondral-separated type was 30.7 years. CT findings (29 ankles) showed sclerosis in seven ankles, micropores in nine, honeycombs in seven, and cysts in six. MRI T2-weighted image findings (28 ankles) showed micro to large pore high signals in the subchondral layers in 18 ankles, low to high mixed signals with poor margins in six, and high signals on the articular surfaces in four. Arthroscopic findings (29 ankles) showed softening of the articular cartilage in two ankles, fissures in 16, bulging and fissures in six, and detachment of the articular cartilage in five. CONCLUSION The onset of these lesions occurred in adults after bone maturity with involvement of the chondral and subchondral layers. Each layer seemed to have experienced different degenerative and reparative processes.

Abstract
PURPOSE The purpose of this study was to review the literature to provide a comprehensive description of the Level of Evidence available to support the surgical technique of ankle arthroscopy for the current generally accepted indications and assign a grade of recommendation for each of them. METHODS A comprehensive review of the literature was performed (in August 2008) by use of the PubMed database. The abstracts from these searches were reviewed to isolate literature that described therapeutic studies investigating the results of different ankle arthroscopic treatment techniques. All articles were reviewed and assigned a classification (I-IV) of Level of Evidence. An analysis of the literature reviewed was used to assign a grade of recommendation for each current generally accepted indication for ankle arthroscopy. RESULTS There exists fair evidence-based literature (grade B) to support a recommendation for the use of ankle arthroscopy for the treatment of ankle impingement and osteochondral lesions and for ankle arthrodesis. Ankle arthroscopy for ankle instability, septic arthritis, arthrofibrosis, and removal of loose bodies is supported with only poor-quality evidence (grade C). Treatment of ankle arthritis, excluding isolated bony impingement, is not effective and therefore this indication is not recommended (grade C against). Finally, there is insufficient evidence-based literature to support or refute the benefit of arthroscopy for the management of synovitis and fractures (grade I). CONCLUSIONS There exists adequate evidence-based literature to support the surgical technique of ankle arthroscopy for most current generally accepted indications; however, further studies in this area are needed. LEVEL OF EVIDENCE Level IV, systematic review.

Abstract
Characterizing osteochondral lesions of the talus has enabled the strategies of surgical management to be better specified. The main technical problem is one of access for arthroscopy instruments to posteromedial lesions. A range of techniques and approaches has been described in ankle arthroscopy in general, and a transmalleolar approach provides reliable and efficient access in these cases. It is frequently used for transchondral drilling, but also enables satisfactory implant positioning in autologous osteochondral mosaicplasty procedures. We report our technique and results on five cases with a minimum 1.2 years' follow-up.
