외상 후 족관절 연부조직 충돌증후군: 관절경적 및 영상의학적 분석 = Post-traumatic Soft Tissue Impingement in Ankle Joint: Arthroscopic & Radiographic Evaluation

다국어 초록 (Multilingual Abstract)

We evaluated the arthroscopic and MRI findings of the post-traumatic ankle soft tissue impingement (ASTI) and the clinical outcome of arthroscopic debridement. Thirty-one ASTI patients were treated with arthroscopic debridement from 2006 to 2008 and 24 patients were followed-up for at least 6 months. Mean age at surgery was 33.0 year-old and mean follow-up period was 16 months. Twenty-nine cases had past trauma history of ankle sprain. The locations of the soft tissue lesions were 42% at anterolateral, 19% anteromedial and 3% medial gutter of the ankle joint. Synovitis was 58% while fibrotic lesion was 32%. VAS pain score decreased from mean 6.8 to 2.2 and American Orthopedic Foot and Ankle Society (AOFAS) functional score also improved from mean 64 to 89 after surgery (p<0.05). Twenty-two patients (92%) were satisfied with the surgery. We found that the diagnostic rate of the ASTI was 75% by MRI and the soft tissue impingement lesions were more common with synovitis than fibrosis. We also achieved favorable clinical outcome with arthroscopic debridement.
