Ankle arthroscopy is a useful tool for detection and treatment of accompanying intraarticular pathologies in acute ankle fractures. The purpose of this study was to compare the treatment results of talus osteochondral lesions (OLT) with debridement and microfracture in arthroscopy assisted surgery of acute ankle fractures.
Eleven consecutive patients who were treated with arthroscopic acute debridement and 14 consecutive patients who were treated with arthroscopic acute microfracture in the treatment of ankle fracture were included in the study. All patients were controlled clinically and radiologically in the postoperative period. Ankle pain was evaluated with the visual analog score (VAS), ankle functions were assessed with American Orthopaedic Foot and Ankle Society Ankle-Hindfoot Scale (AOFAS), and osteoarthritic changes were analyzed with Van Dijk score.
There was no significant difference between the groups in terms of age, gender, injury side and trauma mechanism (n.s). Mean time to surgery, fracture healing duration, first weight-bearing and full weight-bearing, follow-up period and Van Dijk score were all similar in both groups (n.s). The AOFAS score and VAS activity score were statistically significantly better in the microfracture group (p = 0.044 and p = 0.001).
Level III.
The clinical relevance of the present study is to define the acute treatment of the first osteochondral damage that occurred simultaneously with ankle fracture, to improve postoperative functional outcomes and to prevent post-traumatic osteoarthritis. Both debridement and microfracture yield good functional outcomes in the second year of the treatment. Microfracture ensures significantly more successful clinical results than debridement.
