거골의 골연골 병변의 관절경적 치료

Abstract

Purpose: The purpose of this study was to evaluate outcome of ankle arthroscopy with high anteromedial and anterolateral portals for osteochondral talar lesion. Materials and Methods: A prospective study was conducted between March 1992 and January 2000 by one surgeon. Total 48 patients who had osteochondral talar lesion were included. Using high anteromedial and anterolateral portals, arthroscopic treatment was performed. A functional evaluation was performed with the Karlsson scoring scale. Results: Of the 48 patients, 28 cases had anterolateral talar lesion and 18 cases had medial talar lesion and 2 cases had central lesion. The 42 cases(87.5 %) had trauma history. On Karlsson scoring scale, anterolateral talar lesion was better than medial talar lesion(p=0.035). Conclusion: Using high portals, we could get better visualization of talar dome and posterior chamber of ankle, and do some limited procedures without additional portals. Osteochondral lesions were treated successfully only when they were traumatically induced and localized without diffuse chondromalacia of talus and tibia.
