Title: Open versus Endoscopic Excision of a Symptomatic Os Trigonum: A Comparative Study of 41 Cases

Purpose: To compare the clinical results of a consecutive series of 43 cases excision of a symptomatic os trigonum performed with an open versus hindfoot endoscopic technique. Methods: from 1994 to 2007, 43 patients underwent a symptomatic os trigonum excision. Subjective satisfaction questionnaire, a visual analog scale (VAS) for pain, the American Orthopaedic Foot & Ankle Society (AOFAS) ankle and hindfoot scoring system, and the time return to previous sports level from 41 of 43 patients were obtained at follow-up. Sixteen ankles had an open os trigonum excision and 25 ankles had a hindfoot endoscopic surgery. Groups A (16 ankles, open surgery) and B (25 ankles, endoscopic excision) were comparable concerning age, sex, profession, and accompanied injury of the ankle. Results: At follow-up evaluation (12 to 86months after surgery), group B had a significantly shorter period on the average time return to previous sport level. There was no difference on postoperative VAS score, AOFAS score, subjective satisfactory rate and rate of sensory nerve loss between the two groups. Conclusions: Both open surgery and hindfoot endoscopic excision of a symptomatic os trigonum were effective and safe. Patients with an endoscopic excision had a shorter period return to previous sports level.北京大学第三医院运动医学科郭秦炜
