Twenty-eight patients treated by total ankle arthroplasty at the University of California, Irvine, were evaluated on a 100-point ankle analysis scale preoperatively and postoperatively. The average preoperative score was 35 and the average postoperative score was 74. Significant improvement occurred in function, pain relief and range of motion. The average follow-up period for these patients was 9 months. Although the number in each group is small, it does not appear that the procedure has merit for the treatment of ankle arthritis from such diverse causes as trauma, rheumatoid arthritis, aseptic necrosis of the talus and talectomy. Complications included wound healing problems in 3 patients. Malalignment of the prosthesis occurred in 2 other patients; one required revision. Ankle replacement failed in 2 patients. One patient required a fusion; the other an amputation following occlusion of the posterior tibial artery after surgery. At the present time, ankle replacement appears to be an acceptable alternative to ankle arthrodesis.
加利福尼亚大学欧文分校对28例行全踝关节置换术的患者在术前和术后采用100分踝关节分析量表进行评估。术前平均评分为35分，术后平均评分为74分。在功能、疼痛缓解和活动范围方面有显著改善。这些患者的平均随访期为9个月。尽管每组病例数较少，但对于因创伤、类风湿性关节炎、距骨无菌性坏死和距骨切除等多种原因引起的踝关节关节炎，该手术似乎并无优势。并发症包括3例伤口愈合问题。另外2例患者出现假体排列不齐；其中1例需要翻修。2例患者踝关节置换失败。1例患者需要行关节融合术；另1例在术后胫后动脉闭塞后需要截肢。目前，踝关节置换似乎是踝关节融合术可接受的替代方案。
