This study evaluated the changes in the range of motion (ROM) with time postoperatively.
The pre- and intraoperative ROM was compared with the ROM 3, 6, 12, and 24 months postoperatively to clarify the effects of posterior cruciate ligament-retaining (PCLR) and posterior cruciate ligament-sacrificing (PCLS) prostheses on the ROM. The changes in the ROM in PCLR (n = 57) and PCLS (n = 51) mobile-bearing total knee arthroplasties for osteoarthritis patients for whom complete data were available were examined.
No significant difference was seen between the two prostheses at any time point. Nevertheless, the ROM 24 months after PCLR and PCLS prostheses could be predicted statistically from the ROM after 6 and 3 months, respectively.
This study showed the effects of retention of the PCL and the degree of its functional recovery on postoperative ROM for the two prostheses.
本研究评估了术后时间对关节活动度（ROM）的变化。
比较术前和术中 ROM 与术后 3、6、12 和 24 个月的 ROM，以阐明保留后交叉韧带（PCLR）和牺牲后交叉韧带（PCLS）假体对 ROM 的影响。对有完整数据的骨关节炎患者接受的 PCLR（n=57）和 PCLS（n=51）活动平台全膝关节置换术中的 ROM 变化进行了检查。
在任何时间点，两种假体之间均无显著差异。然而，PCLR 和 PCLS 假体在术后 6 个月和 3 个月后的 ROM 可以通过统计学预测 24 个月后的 ROM。
本研究表明保留后交叉韧带及其功能恢复程度对两种假体术后 ROM 的影响。
