OBJECTIVES: The aim of this study was to evaluate early results of open mosaicplasty for the treatment of talus osteochondral lesions associated with chronic complaints. METHODS: The study included eight patients (1 male, 7 females; mean age 35 years; range 18 to 74 years) with osteochondral lesions of the talar dome. The mean duration of symptoms was 11 months and the mean lesion size was 17 x 9 mm. The lesions were of medial localization in five patients, and lateral localization in three patients. According to the Bristol classification, the stages of the lesions were as follows: stage IIa (n=2), IIb (n=1), III (n=2), IV (n=1), and V (n=2). Mosaicplasty was performed via a mini arthrotomy with osteotomy. Functional assessments were made using the AOFAS (American Orthopaedic Foot & Ankle Society) scoring system pre- and postoperatively. Pain was assessed using a visual analog scale. Regeneration of new cartilage tissue at the lesion site was monitored by magnetic resonance imaging. The mean follow-up was 17 months (range 8 to 34 months). RESULTS: The osteotomy site healed in a mean of six weeks in all the patients. The mean pre- and postoperative AOFAS scores were 58 (range 40-68) and 89 (range 80-97), respectively (p<0.005). Pain scores decreased from a mean of 8 (range 5 to 10) to 2 (range 1 to 4; p<0.005). Surgery-related complication was seen in one patient. All the patients returned to preoperative levels of activity and occupation. Magnetic resonance imaging showed graft incorporation in all the patients. CONCLUSION: Open mosaicplasty is a simple, safe, and effective alternative in the treatment of cartilage losses of the talar dome, in particular those of cystic type and exceeding 10 mm in size.
