The 4-year outcomes of a prospective study of patients undergoing Triathlon total knee arthroplasty (TKA) are presented. There were 2035 consecutive cemented TKAs performed on 1688 patients. Mean follow-up was 21 months, including 713 knees with a follow-up of > or =2 years. In a subgroup of 239 patients, the coverage of the patella cut surface by the patella component was analyzed. To our knowledge, this is the first article to study this issue. Mean Knee Society pain scores improved from 48 to 96, function improved from 63 to 85, and range of motion improved from a mean of -5 degrees to 104 degrees to a mean of -2 degrees to 126 degrees. Coverage of the patella by the prosthesis was full from medial to lateral in 88% and full from proximal to distal in 91% of knees. The implant system has performed well within the follow-up period, with no implant- or design-related failures.
本文介绍了一项针对接受铁人三项全膝关节置换术（TKA）患者的前瞻性研究的4年结果。对1688例患者连续进行了2035例骨水泥型TKA。平均随访时间为21个月，其中713例膝关节的随访时间≥2年。在239例患者的亚组中，分析了髌骨假体对髌骨截骨面的覆盖情况。据我们所知，这是第一篇研究该问题的文章。膝关节协会平均疼痛评分从48分提高到96分，功能评分从63分提高到85分，活动范围从平均-5度到104度提高到平均-2度到126度。假体对髌骨的覆盖在内侧到外侧方向上88%的膝关节为完全覆盖，在近端到远端方向上91%的膝关节为完全覆盖。在随访期间，植入系统表现良好，未出现与植入物或设计相关的故障。
