older adults with total knee arthroplasty (TKA) frequently undergo rehabilitation to address limited knee flexion range-of-motion, quadriceps weakness and gait speed limitations. This study aimed to develop age- and sex-specific recovery curves of knee flexion range-of-motion, quadriceps strength and fast gait speed post-TKA.
a population-based sample of 2,987 patients undergoing primary TKA participated, of whom 2015 (68%) were 65 years of age or older. At 4, 8 and 12 weeks post surgery, knee flexion range-of-motion, quadriceps strength and fast gait speed were quantified. Quantile regression was used to determine the percentiles of the knee and gait measures.
the various knee and gait measures improved nonlinearly over time, with substantial improvements observed in the 1st 8-10 weeks post surgery. Age-specific, sex-specific recovery curves were developed to show the recovery patterns at multiple percentile levels. A web interface was created to facilitate easy computation of the percentile rank for a given outcome value.
we have provided reference percentile values for knee flexion range-of-motion, quadriceps strength and gait speed recovery post-TKA. Such information may assist rehabilitation professionals in interpreting outcomes and quantifying deviations from the expected recovery pattern.
全膝关节置换术（TKA）后的老年患者常需接受康复治疗，以解决膝关节活动度受限、股四头肌无力和步速受限等问题。本研究旨在建立 TKA 后膝关节活动度、股四头肌力量和快速步速的年龄和性别特异性恢复曲线。
本研究纳入了一个基于人群的 2987 例初次 TKA 患者，其中 65 岁及以上患者 2015 例（68%）。在术后 4、8 和 12 周时，对膝关节活动度、股四头肌力量和快速步速进行量化。使用分位数回归确定膝关节和步态测量的百分位数。
各项膝关节和步态测量指标随时间呈非线性改善，术后 8-10 周内观察到显著改善。为了展示多个百分位水平的恢复模式，制定了年龄特异性和性别特异性的恢复曲线。创建了一个网络界面，以方便计算给定结果值的百分位排名。
我们提供了 TKA 后膝关节活动度、股四头肌力量和步态速度恢复的参考百分位值。这些信息可能有助于康复专业人员解释结果，并量化与预期恢复模式的偏差。
