Polycentric total knee arthroplasty in 56 patients provided significant relief of pain in 90.7% and a stable knee in 92.7%. Postoperative increase in range of motion averaged 13.7 degrees for all patients (18.5 degrees in rheumatoid arthritis and 8.7 degrees in degenerative arthritis). This increase in excursion is attributed to the design of the prosthesis, a vigorous postoperative rehabilitation program, and careful surgical technic. A failure rate of 12.7% was due to infection, mechanical instability and unexplained pain. Contraindications to surgery and technical recommendations are noted.
对56例患者进行多中心全膝关节置换术，90.7%的患者疼痛得到显著缓解，92.7%的患者膝关节保持稳定。所有患者术后活动范围平均增加13.7度（类风湿性关节炎患者增加18.5度，退行性关节炎患者增加8.7度）。活动范围的增加归因于假体设计、积极的术后康复计划和精细的手术技术。12.7%的失败率是由感染、机械不稳定和不明原因疼痛导致的。文中指出了手术禁忌症和技术建议。
