This prospective study evaluated the results of arthroscopic subtalar arthrodesis for painful hindfoot osteoarthritis.
The hypotheses were that (1) the arthroscopic technique results in a reliable fusion rate, (2) the clinical outcome is better than the open procedure and (3) complication rates are lower. Forty-one arthroscopic subtalar fusions were done in 37 consecutive symptomatic patients without hindfoot deformity between December, 1997, and May, 2003. Indications for fusion were persistent pain with reduced range of motion and impaired daily activities.
The average modified AOFAS ankle-hindfoot score improved from 53 (range 22 to 69) points preoperatively to 84 (range 41 to 94) points at final follow-up (average 55 months, range 24 to 89 months). Union was achieved in all cases. Radiographic progression of degeneration in the adjacent joints was observed in three patients.
In painful hindfoot osteoarthritis the arthroscopic technique provides reliable fusion and high patient satisfaction with the advantages of a minimally invasive procedure.
本前瞻性研究评估了关节镜下距下关节融合术治疗疼痛性后足骨关节炎的结果。
研究假设为：（1）关节镜技术能实现可靠的融合率；（2）临床结果优于开放手术；（3）并发症发生率更低。1997年12月至2003年5月期间，对37例连续的有症状且无后足畸形的患者进行了41例关节镜下距下关节融合术。融合的指征为持续性疼痛、活动范围减小以及日常活动受限。
平均改良AOFAS踝 - 后足评分从术前的53分（范围22至69分）提高到末次随访时的84分（范围41至94分）（平均55个月，范围24至89个月）。所有病例均实现融合。3例患者观察到相邻关节退变的影像学进展。
在疼痛性后足骨关节炎中，关节镜技术可提供可靠的融合，患者满意度高，且具有微创手术的优势。
