Introduction Studies evaluating the outcomes of different brands of knee prostheses are important to monitor patient outcomes and generate evidence to aid decisions around the choice of implant. The Triathlon® prosthesis (Stryker, Limerick, Ireland), one of the most commonly used total condylar knee prosthesis, is designed to provide greater knee motion and the potential for longer implant survivorship. The aim of this cohort study was to evaluate outcomes and survivorship of the Triathlon total knee replacement (TKR) up to 10 years post-operative. Methods Two-hundred sixty-six (266) patients listed for a Triathlon TKR in one orthopaedic hospital were recruited. Assessments were conducted preoperatively and then at three months and one, two, three, five, seven, and 10 years after surgery. Outcomes assessed included pain, function, knee-related quality of life (QoL), satisfaction, kneeling ability, activity levels, American Knee Society Score, complications, and survivorship. Results Large improvements in patient-reported outcomes were observed in the first three months after surgery, followed by small improvement up to one year post-operative, and then outcomes plateaued up to 10 years post-operative. Satisfaction with overall outcome ranged from 79%-94% over the duration of follow-up. Activity levels and kneeling ability were similar before and after surgery. There was a large improvement in the median American Knee Society score in the first three months post-operative, followed by a small but gradual improvement to 10 years post-operative. Survivorship was 95.4% (95% confidence interval 91.8-97.5%) at 10 years post-operative. Conclusions This study found that the Triathlon TKR results in excellent outcomes and survivorship to 10 years post-operative.
引言 评估不同品牌膝关节假体的效果对于监测患者预后并为植入物选择决策提供证据非常重要。Triathlon® 假体（史赛克公司，爱尔兰利默里克）是最常用的全髁膝关节假体之一，旨在提供更大的膝关节活动度并有可能实现更长的假体使用寿命。本队列研究的目的是评估 Triathlon 全膝关节置换术（TKR）术后长达 10 年的效果和生存率。方法 在一家骨科医院招募了 266 名计划进行 Triathlon TKR 的患者。术前以及术后三个月、一年、两年、三年、五年、七年和 10 年进行评估。评估的结果包括疼痛、功能、膝关节相关生活质量（QoL）、满意度、跪姿能力、活动水平、美国膝关节协会评分、并发症和生存率。结果 在术后前三个月观察到患者报告的结果有大幅改善，随后在术后一年有小幅改善，然后在术后长达 10 年结果趋于平稳。在随访期间，对总体结果的满意度为 79% - 94%。手术前后的活动水平和跪姿能力相似。术后前三个月美国膝关节协会评分中位数有大幅提高，随后到术后 10 年有小幅但逐渐的改善。术后 10 年生存率为 95.4%（95% 置信区间 91.8 - 97.5%）。结论 本研究发现 Triathlon TKR 术后 10 年的效果和生存率极佳。
