全膝关节置换术（TKA）的结果并不总是令人满意的。本研究的目的是确定采用解剖学单半径设计或内侧枢轴设计进行TKA的患者的步态满意度和生物力学特征。我们假设后者将提供更好的上级功能。这是一项前瞻性随机研究中招募的患者子集的研究，研究采用单半径设计与内侧枢轴设计，至少随访1年。结果测量包括临床评分（膝关节协会评分（KSS）和牛津膝关节评分（OKS））和使用仪器跑步机的步态分析。两组之间的KSS和OKS无统计学显著差异。步频、步行速度、步幅和站立时间、最大步幅、中间支撑力和推离力也无统计学意义。本研究证实了同一作者先前的一项研究，该研究显示，在严格的测试条件下，传统单半径和内侧枢轴设计在临床结局和步态方面具有同样良好的结果。引用这篇文章：Bone Joint J 2018;（1 Supple A）100-B：76-82。
The outcome of total knee arthroplasty (TKA) is not always satisfactory. The purpose of this study was to identify satisfaction and biomechanical features characterising the gait of patients who had undergone TKA with either an anatomical single radius design or a medial pivot design. We hypothesised that the latter would provide superior function. This is a study of a subset of patients recruited into a prospective randomised study of a single radius design versus a medial pivot design, with a minimum follow-up of one year. Outcome measurements included clinical scores (Knee Society Score (KSS) and Oxford Knee Score (OKS)) and gait analysis using an instrumented treadmill. There was no statistically significant difference between the two groups for both the KSS and OKS. There was also no statistical significance in cadence, walking speed, stride length and stance time, peak stride, mid support and push-off forces. This study corroborates a previous study by the same authors that showed equally good results in clinical outcome and gait between the conventional single radius and medial pivot designs under stringent testing conditions.
