Ankle Lesions, Associated with Anterior Soft Tissue Impingement / 대한족부족관절학회지

ABSTRACT

PURPOSE: To evaluate clinical features of ankle lesions, associated with anterior soft tissue impingement. MATERIALS AND METHODS: We retrospectively reviewed 21 patients who had chronic anterior ankle pain as initial symptom and associated ankle lesions with anterior soft tissue impingement. Based on preoperative radiologic findings, physical examination intra-operative findings, appropriate procedures were done for lesions by either arthroscopic or minimal open procedure or combined. Clinical evaluation was done using American Orthopedic Foot and Ankle Society, ankle-hind foot score (AOFAS score) and visual analog scale (VAS) on last follow up. RESULTS: Associated lesion(s) to anterior soft tissue impingement of the ankle were 16 cases of osteochondral lesion of talus, 14 cases of bony impingement, 6 cases of ankle lateral instability, 5 cases of loose body, 4 cases of os subfibulare. AOFAS score was 58.9 +/- 5.1 preoperatively and 74 +/- 9.1 on last follow up. Clinical satisfaction score using VAS showed excellent in 3 cases, good in 11, fair in 3, poor in 4. CONCLUSION: The patients who had anterior soft tissue impingement would have various associated lesions on their ankle. In such cases, preoperative counseling for variety of postoperative results would be needed.
