This study evaluates a possible change in the demographics and surgical practice observed in a large cohort of patients undergoing total knee replacement (TKR).
We performed a retrospective analysis of a prospectively collected data on two groups of consecutive patients undergoing primary TKR. Group one consisted of patients who underwent surgery between 1994 and 1998. Group two consisted of patients who had surgery between 2009 and 2012.
The mean age of group two was significantly greater than that of group one: 68.9 years (68.1-69.7 years) for group one versus 70.1 years (69.6-70.6 years) for group two (p = 0.009). The mean BMI of group two was significantly greater than that of group one: 29.5 kg/m (29.0-29.9 kg/m) for group one versus 32.0 kg/m (31.7-32.3 kg/m) for group two (p < 0.001). The mean pain component of the AKSS was significantly worse in group one than in group two: 28.6 (27.2-30.0) for group one versus 35.5 (34.6-36.4) for group two (p < 0.001). The mean function component of the AKSS was significantly worse in group one than in group two: 48.6 (47.3-49.9) for group one versus 51.5 (50.7-52.3) for group two (p < 0.001).
This study describes the change in demographics of patients undergoing TKR in our institution over the last two decades.
本研究评估了在接受全膝关节置换术（TKR）的大量患者队列中观察到的人口统计学和手术实践的可能变化。
我们对前瞻性收集的两组连续接受初次TKR患者的数据进行了回顾性分析。第一组由1994年至1998年接受手术的患者组成。第二组由2009年至2012年接受手术的患者组成。
第二组的平均年龄显著高于第一组：第一组为68.9岁（68.1 - 69.7岁），第二组为70.1岁（69.6 - 70.6岁）（p = 0.009）。第二组的平均体重指数显著高于第一组：第一组为29.5kg/m²（29.0 - 29.9kg/m²），第二组为32.0kg/m²（31.7 - 32.3kg/m²）（p < 0.001）。第一组的美国膝关节协会评分（AKSS）的平均疼痛分量显著差于第二组：第一组为28.6（27.2 - 30.0），第二组为35.5（34.6 - 36.4）（p < 0.001）。第一组的AKSS平均功能分量显著差于第二组：第一组为48.6（47.3 - 49.9），第二组为51.5（50.7 - 52.3）（p < 0.001）。
本研究描述了过去二十年来我们机构接受TKR患者的人口统计学变化。
