Background: Severe posttraumatic ankle arthritis poses a reconstructive challenge in the young and active patient. Bipolar fresh total osteochondral allograft (BFTOA) may represent an intriguing alternative to arthrodesis and prosthetic replacement. The purpose of this article was to evaluate the outcomes of BFTOA performed through an anterior approach to the ankle and to investigate the parameters influencing the results. Methods: A total of 26 patients (18 males and 8 females with a mean age of 34.9 ± 7.7 years) underwent BFTOA. The allograft was prepared with the help of specifically designed jigs and the surgery was performed using a direct anterior approach. Patients were evaluated clinically and radiographically at 2, 4, 6, and 12 months after the operation, and at a mean 40.9 ± 14.1 months of follow-up. Radiographic evaluation included the measurement of allograft size matching and alignment. Results: The AOFAS score improved from 26.6 ± 6 preoperatively to 77.8 ± 8.7 after a mean follow-up of 40.9 ± 14.1 months (P < .0005). Six failures occurred. Joint degeneration was classified as 2 in 12 and as 3 in 14 patients. A statistically significant correlation between low degrees of distal tibial slope and better clinical outcomes was observed (P = .049). Conclusion: BFTOA appears to be a viable option to arthrodesis or arthroplasty. Precise allograft sizing, stable fitting, and fixation and delayed weight-bearing were key factors for a successful outcome. In this series the correct alignment of the tibial graft, in terms of slope, was found to play a crucial role in the allograft survivorship. Level of Evidence: Level IV, case series.

Background: Anterior soft tissue impingement of the ankle has been described based on the etiology and location, but no classification has been reported. Arthroscopic treatment is usually considered effective, even if the behavior of the different forms of impingement is not clear. The purpose of this study was to analyze the factors affecting long-term results. Methods: Forty-two patients with a mean age of 32.6 years were arthroscopically treated between 2004 and 2008. Impingement lesions were identified according to clinical examination and confirmed by MRI. Soft tissue impingement was detected and classified according to location (anteromedial, anterolateral, syndesmotic or diffuse). Patient data, foot morphology, and previous trauma or surgery were recorded. Patients were evaluated after a mean of 90.1 months’ follow-up with the American Orthopaedic Foot & Ankle Society (AOFAS) scoring system. Results: The mean AOFAS score improved from 40.6 preoperatively to 82.6, 78.4, and 74.8, respectively, at the 2-, 4-, and 6-year follow-ups (P < .05). The anterolateral form showed higher scores compared to the diffuse or anteromedial forms. Age, foot morphology, and previous trauma or surgery did not affect the results. Body mass index of more than 26 and male gender were associated with worse outcomes. Conclusion: Arthroscopic debridement proved effective in the treatment of soft tissue impingement. Furthermore, we were able to classify the location of the anterior soft tissue impingement of the ankle, which may have prognostic importance. Level of Evidence: Level IV, case series.

The purpose of this study is to (1) report the long-term clinical and radiographic outcomes of a nonanatomical anterior cruciate ligament (ACL) reconstruction using an over-the-top (OTT) femoral route and (2) compare single-strand (1SHG) and double-strand (2SHG) hamstrings graft reconstruction. Fifty-one consecutive patients (mean age, 29.2±3.8 years) underwent nonanatomical ACL reconstruction using OTT femoral passage. Twenty patients underwent 1SHG reconstruction and 31 underwent 2SHG reconstruction. International Knee Documentation Committee (IKDC) score, Knee Injury and Osteoarthritis Outcome Score (KOOS), Tegner score, and KT-1000 (Medmetric Corporation, San Diego, California) evaluation were recorded at a mean follow-up of 12.1±1.6 years. At final follow-up, radiographic evaluation was performed according to the IKDC grading system. Mean IKDC subjective score at follow-up was 76.6±21.9 in the 1SHG group and 88.9±10.0 in the 2SHG (P=.009). Average KOOS was 82.6±18.7 in the 1SHG group and 92.4±9.2 in the 2SHG group (P=.016). Objective IKDC evaluation showed a higher percentage of normal knees in the 2SHG group (P=.018). Pivot shift testing revealed a significantly higher number of normal knees in the 2SHG group (P=.001). Radiographs showed fewer degenerative changes in the 2SHG group at final follow-up in the medial (P=.01) and lateral (P=.037) compartments. Nonanatomical ACL reconstruction using the OTT technique provided satisfactory results in terms of control of both static and dynamic instability at long-term follow-up, thus preventing degenerative joint disease. The 2SHG group showed better subjective and functional outcomes with fewer degenerative changes compared with the 1SHG group at long-term follow-up.

Background: Juvenile osteochondritis dissecans of the talus (JOCDT) is a focal idiopathic lesion primarily of the subchondral bone leading to subsequent cartilaginous damage. The majority of the papers dealing with JOCDT reported heterogeneous case studies of patients treated with different cartilage repair techniques. The purpose of this paper is to retrospectively review both clinical and radiologic results among 7 patients affected by JOCDT treated with arthroscopic bone marrow aspirate concentrate (BMAC) transplantation with the 1-step technique. Methods: Both standard anterior-posterior and lateral radiographs and a 1.5 T magnetic resonance imaging of the affected ankle were preoperatively performed in all the patients. The American Orthopaedic Foot and Ankle Society (AOFAS) score and the visual analogue scale were administered to the patients preoperatively and at the final follow-up. Results: Patients were followed up to an average of 48.1±18.4 months. According to the Berndt and Harty classification, 6 lesions were found to be in stage III and 1 lesion in stage IV. The average preoperative AOFAS score was 58.8±7.6 points. At the mean follow-up of 48.1 months the average AOFAS score improved to 95.7±5.4 points (P<0.05). Visual analogue scale improved from 6.3 preoperatively to 0.4 at final follow-up (P<0.05). Complete radiographic healing, in terms of complete bony filling, was observed in 3 of 7 cases. The magnetic resonance imaging analysis showed a complete filling of the osteochondral defect in 4 patients, whereas in 1 patient a hypotrofic tissue was observed. Conclusions: BMAC transplantation is able to provide good to excellent results in the treatment of JOCDT. The 43% of our patients showed a complete radiographic healing, but all the patients were satisfied with the procedure. Because of the rareness of the lesion, further studies involving more patients and with a longer follow-up are required, to establish the advantage of performing a regenerative procedure like the BMAC transplantation in a pediatric population. Level of Evidence: Level IV.
