The aim of this study was to determine outcomes and survivorship of the Triathlon knee replacement up to 5 years post-operation. A cohort of 266 patients receiving a Triathlon knee replacement were assessed before surgery and at 3 months, 1 year, 2 years, 3 years and 5 years post-operation. Assessments included patient-reported outcome measures, American Knee Society Score, complications and survivorship. The largest improvements in pain, function, stiffness and knee-related quality of life occurred in the first 3 months post-operation. Further smaller improvements were reported between 3 and 12 months post-operation, and then a plateauing of outcomes was observed up to 5 years. A high percentage of patients (86%) were satisfied with their outcome at 5 years. Survivorship with revision as the endpoint was 96.6% (95% CI 93.2-98.1%) at 5 years post-operation. In conclusion, this study observed good mid-term patient outcomes and survivorship of the Triathlon knee replacement.
本研究的目的是确定铁人三项膝关节置换术后长达5年的疗效和生存率。对266例接受铁人三项膝关节置换术的患者在手术前以及术后3个月、1年、2年、3年和5年进行评估。评估内容包括患者报告的结局指标、美国膝关节协会评分、并发症和生存率。疼痛、功能、僵硬程度和膝关节相关生活质量在术后前3个月改善最为明显。术后3至12个月报告有进一步较小程度的改善，然后直至5年观察到疗效趋于平稳。86%的患者在5年时对其治疗效果感到满意。以翻修为终点的5年生存率在术后5年时为96.6%（95%置信区间93.2 - 98.1%）。总之，本研究观察到铁人三项膝关节置换术有良好的中期患者疗效和生存率。
