全膝关节置换术(TKA)的最佳固定方式是一个有争议的话题。我们招募了100名TKA患者，随机分为骨水泥固定组和非骨水泥固定组。记录术前、术后膝关节功能评分(KSS)、牛津评分和疼痛视觉模拟评分(VAS)。93例患者获得两年随访。非骨水泥组术后4个月的平均VAS有升高趋势(P=0.06)。两年后KSS功能评分、牛津评分和自我报告的满意度、疼痛减轻和功能改善问题相似，但骨水泥组的KSS临床评分较高(96.4vs.92.3，P=0.03)。无骨水泥膝关节的放射学透光率较高(P<；0.001)。非骨水泥组有一次因不稳定而翻修，一次骨水泥组因感染而翻修。在早期的随访中，非骨水泥型全膝关节置换术与骨水泥型全膝关节置换术的存活率相当(以任何原因翻修为终点)。密切监测放射透光度对持续的后续行动很重要。(C)2015 Elsevier Inc.保留所有权利。
The optimalmode of fixation in total knee arthroplasty (TKA) is a subject of debate. We enrolled 100 TKA patients randomized to cemented or cementless fixation. Knee Society Scores (KSS), Oxford scores and pain visual analog scales (VAS) were collected pre-operatively and post-operatively. Two-year follow-up was obtained for 93 patients. The mean VAS trended higher for the cementless group at 4 months (P=0.06). At 2 years, the KSS functional scores, Oxford scores, and self-reported questions for satisfaction, less pain and better function were similar but the cemented group had higher KSS clinical scores (96.4 vs. 92.3, P = 0.03). More radiolucencies were seen in cementless knees (P < 0.001). The cementless group had one revision for instability and one cemented knee was revised for infection. Cementless TKA showed equivalent survivorship (revision for any reason as the endpoint) compared to cemented TKA at this early follow-up. Close monitoring of radiolucencies is important with continued follow-up. (C) 2015 Elsevier Inc. All rights reserved.
