Abstract
BACKGROUND: Large cystic osteochondral defects of the talus can be challenging to treat. This retrospective control study looked at the use of osteochondral autograft transfer combined with cancellous allograft in patients with advanced cartilage and subchondral bone damage of the talus. METHODS: Thirteen patients were treated with large cystic osteochondral defect of the talus between February 2010 and July 2013. All of these cystic osteochondral defects were larger than 15 mm in diameter. The subchondral defects were filled with cancellous allograft and the center of the lesions were sealed with an osteochondral cylinder autograft that was harvested from the ipsilateral medial femoral condyle. The visual analog scale (VAS) score for pain during daily activities, American Orthopaedic Foot & Ankle Society Ankle and Hindfoot (AOFAS-AH) scores and subjective satisfaction survey rating were obtained. Plain radiographs and magnetic resonance imaging of the ankle were obtained before and after surgery. In 5 cases, arthroscopy was performed 12 months postoperatively, and the cartilage repair was assessed with the criteria of the International Cartilage Repair Society. Twelve patients were available for follow-up at a mean of 25.4 months (range, 18 to 48 months). RESULTS: Average postoperative AOFAS-AH score 12 months after surgery was 88±7 compared with 64±10 preoperatively. The mean VAS score decreased from 6±1 preoperatively to 1±1 at the latest follow-up. Seven patients rated their result as excellent, 5 as good and none as fair. The radiolucent area of the cysts disappeared on the plain radiographs in all cases. The mean International Cartilage Repair Society arthroscopic score from follow-up arthroscopy was 9±1 points. CONCLUSIONS: The use of osteochondral autograft transfer combined with cancellous allograft was an effective option for the treatment of large cystic talar osteochondral lesions. LEVEL OF EVIDENCE: Level IV, retrospective case series.
