BACKGROUND
The optimal mode of fixation in total knee arthroplasty is a continuing subject of debate.
METHODS
Previously, we reported 2-year results for this prospective, randomized trial. Knee Society Scores, Oxford scores, and pain visual analog scales were collected pre-operatively and post-operatively. Minimum 5-year follow-up has been obtained with radiographic analysis for 85 patients.
RESULTS
Mean Knee Society Scores and Oxford scores and patient-reported outcomes were similar in both groups. Each group had 1 additional revision, but neither was related to implant fixation. Survivorship with revision as an endpoint was equivalent (95.9% and 95.3%, P = .98). There was no significant difference in radiolucencies observed between groups (P = .10), all were non-progressive.
CONCLUSION
Cementless and cemented total knee arthroplasty had equivalent patient-reported outcomes and survivorship at midterm follow-up. Updates are planned at 10 and 15-year intervals to observe long-term modes of failure between these 2 methods of fixation.
背景
全膝关节置换术中的最佳固定方式一直是一个争论的话题。
方法
此前，我们报道了这项前瞻性、随机试验的 2 年结果。术前和术后收集膝关节协会评分、牛津评分和疼痛视觉模拟评分。对 85 例患者进行了至少 5 年的随访，并进行了影像学分析。
结果
两组的平均膝关节协会评分、牛津评分和患者报告的结果相似。每组都有 1 例额外的翻修，但都与植入物固定无关。以翻修为终点的生存率相当（95.9%和 95.3%，P=0.98）。两组之间观察到的放射透亮区无显著差异（P=0.10），均无进行性发展。
结论
在中期随访中，骨水泥固定和非骨水泥固定的全膝关节置换术具有相似的患者报告结果和生存率。计划在 10 年和 15 年的时间间隔进行更新，以观察这两种固定方式之间的长期失效模式。
