UNASSIGNED: A prospectively collected cohort of 255 patients undergoing fixed-bearing UKA of the lateral compartment using the Triathlon PKR (Stryker, Warsaw, IND) implant with a minimum 2-year follow-up was reviewed. The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score, radiographic alignment, complications, reoperations, and revisions were recorded. Patient factors and pre- and post-surgical alignment were assessed for their association with a minimum important change (MIC) of the total WOMAC score.
UNASSIGNED: A total of 246 implants with a mean follow-up of 6.6 years (2-10.8 years) were included (4% lost to follow-up). The total WOMAC score increased from 61.3 ± 3.5 to 85.3 ± 7.5, exceeding the MIC in 215 patients (88%). Exceeding the MIC was not associated with age, body mass index, or alignment. The 5-year implant revision rate was 1.6% (3/187).
UNASSIGNED: The fixed-bearing Stryker Triathlon PKR implant for lateral UKA resulted in good clinical outcomes with a low revision rate at midterm follow-up. Body mass index, age, and pre- and post-surgical alignment did not correlate with the clinical outcome. Long-term follow-up is necessary to determine if the clinical improvement and low revision rate can be maintained.
■一项前瞻性收集的队列,包括255名使用铁人三项PKR进行侧室固定轴承UKA的患者(Stryker,华沙,对至少2年随访的IND)植入物进行了审查。西安大略省和麦克马斯特大学骨关节炎指数(WOMAC)评分,射线照相校准,并发症,重新操作,并记录了修订。评估患者因素以及手术前后对齐与WOMAC总分的最小重要变化(MIC)的相关性。
■总共包括246个植入物,平均随访6.6年(2-10.8年)(4%的随访损失)。WOMAC总分从61.3±3.5增加到85.3±7.5,超过215例患者的MIC(88%)。超过MIC与年龄无关,身体质量指数,或对齐。5年植入物翻修率为1.6%(3/187)。
■用于外侧UKA的固定轴承Stryker铁人三项PKR植入物在中期随访中具有较低的翻修率,具有良好的临床效果。身体质量指数,年龄,术前和术后排列与临床结局无关.需要长期随访以确定是否可以维持临床改善和低修订率。
