Total knee designs have evolved to allow more motion with compromising stability. The purpose of this study is to compare standard congruency and anterior lipped liners' effects on patient reported outcomes after TKA. 68 patients were retrospectively reviewed, and their SF-12 and KOOS scores were assessed preoperatively and one year post-operatively. Two-sample t-tests were used to compare differences between groups. The CVD design had a statistically significant greater improvement in KOOS-Pain compared to CVD+. No statistical difference was observed in the outcomes. The results may suggest that higher congruency designs lead to less physiological joint kinematics and pain.
全膝关节设计已经发展到能够在不影响稳定性的情况下实现更多的活动度。本研究的目的是比较标准贴合型和前唇衬垫对全膝关节置换术后患者报告结局的影响。对68例患者进行回顾性分析,在术前和术后一年评估他们的SF-12和膝关节损伤与骨关节炎疗效评分系统(KOOS)得分。采用双样本t检验比较组间差异。与CVD+相比,CVD设计在KOOS疼痛方面有统计学意义上的更大改善。在结局方面未观察到统计学差异。结果可能表明,更高贴合度的设计会导致更少的生理性关节运动学变化和疼痛。
