Between March 9, 1972 and December 31, 1973, a total of 103 UCI knee replacements were performed. Follow-up data are available on 83 knees with an average follow-up of 33 months. Patient evaluation of the end results indicates that 78.3 per cent were better, 9.6 per cent unchanged, and 12.1 per cent worse. Patient evaluation of their own knee function averaged 55 per cent preoperatively and 79 per cent postoperatively. Patients were also evaluated on a 100 point Modified Larson Analysis Form. The average preoperative score was 46, and the average postoperative score was 70. There were six (5.8%) biological complications in the 103 knee replacement. Biological complications included infections, wound healing problems and unexplained pain. Mechanical complications were seen in 18 (17.4%) knees, and included knee instability, tibial component loosening or deformation, and patellar problems. Additional surgery was required in 18 (17.4%) knees. Failure of the procedure eventually requiring removal of the prosthesis and fusion or amputation occurred in 4 (3.9%) knees. The intermediate-term results of UCI knee replacement have been clinically satisfactory. We currently recommend consideration of this procedure for patients with disabling arthritis of the knee.
1972年3月9日至1973年12月31日期间，共进行了103例UCI膝关节置换手术。现有83个膝关节的随访数据，平均随访时间为33个月。患者对最终结果的评估表明，78.3%的情况有所改善，9.6%无变化，12.1%变差。患者对自身膝关节功能的评估术前平均为55%，术后为79%。患者还通过100分的改良拉森分析表进行评估。术前平均评分为46分，术后平均评分为70分。103例膝关节置换中有6例（5.8%）出现生物学并发症。生物学并发症包括感染、伤口愈合问题和不明原因疼痛。18个（17.4%）膝关节出现机械并发症，包括膝关节不稳定、胫骨部件松动或变形以及髌骨问题。18个（17.4%）膝关节需要再次手术。手术失败最终需要取出假体并进行融合或截肢的情况在4个（3.9%）膝关节中出现。UCI膝关节置换的中期结果在临床上令人满意。我们目前建议考虑对膝关节致残性关节炎患者采用该手术。
