The aim of this study was to investigate the results of different treatment strategies for osteochondral defects (OCD) of the talus. Electronic databases from 1966 to July 1998 were systematically screened. Based on our inclusion criteria 32 studies describing the results of treatment strategies for OCD of the talus were included. No randomized clinical trials (RCT’s) were identified. Fourteen studies described the results of excision alone, 11 the results of (EC), 14 the results of (ECD), 1 the results of cancellous bone grafting after EC, 1 the results of osteochondral transplantation and 3 the results of fixation. The average success rate of non-operative treatment (NT) was 45%. Comparison of different surgical procedures shows that the average highest success rate was reached by excision, curettage and drilling (ECD) (85%) followed by excision and curettage (EC) (78%) and excision alone (38%). Based on this systematic review we conclude that NT and excision alone are not to be recommended in treating talar OCD. Both EC and ECD have been shown to lead to a high percentage good/excellent results. However, due to great diversity in the articles and variability in treatment results, no definitive conclusions can be drawn. Further prospective randomized controlled trials are required to compare the outcome of these two surgical strategies for OCD of the talus.
