A total of 109 consecutive total condylar knee replacements in 73 patients were assessed at one to eight years postoperatively. The average age at surgery was 66.9 years and the range was from 52 to 84 years. The primary disease was rheumatoid arthritis in 12 and degenerative osteoarthritis in 97 knees. Out of the 109 prostheses; 101 were Miller-Galante kinematic condylar type I or II prostheses, seven were Insall-Burstern type I or II and one was a Whiteside prosthesis. The fixation technique was hybrid (only the tibial prosthesis cemented) in 63, both components uncemented in two and both components cemented in 44 knees. One hundred and five (96.3%) knees showed significant improvement in the Hospital for Special Surgery score postoperatively. The average preoperative score was 48.1 and the postoperative score was 85.4. Sixty-four patients (100 knees) were satisfied or very satisfied with the result of surgery. One hundred and four (95.4%) knees had achieved either an improvement in the range of motion and/or deformity. Complications included loosening in four (3.7%) knees, infection in three (2.8%), dislocation of the patella in four (3.7%), periprosthetic fracture in one (0.9%) and severe lateral collateral ligamentous laxity in one (0.9%).
对73例患者连续进行的109例全髁膝关节置换术在术后1至8年进行了评估。手术时的平均年龄为66.9岁，范围为52至84岁。原发性疾病为类风湿关节炎12例，退行性骨关节炎97例膝关节。在109个假体中，101个是Miller-Galante运动髁I型或II型假体，7个是Insall-Burstern I型或II型，1个是Whiteside假体。固定技术为混合固定（仅胫骨假体用骨水泥固定）63例，两个组件均非骨水泥固定2例，两个组件均用骨水泥固定44例膝关节。105个（96.3%）膝关节术后在特种外科医院评分中显示出显著改善。术前平均评分为48.1，术后评分为85.4。64例患者（100个膝关节）对手术结果满意或非常满意。104个（95.4%）膝关节在活动范围和/或畸形方面有改善。并发症包括4个（3.7%）膝关节松动，3个（2.8%）感染，4个（3.7%）髌骨脱位，1个（0.9%）假体周围骨折，1个（0.9%）严重外侧副韧带松弛。
