METHODS: A total of 136 consecutive patients who underwent TKA were included in this study. Half of the patients underwent RA-TKA and the other half underwent conventional TKA (CON-TKA) by the same group of surgeons. Collect the relevant parameters.
RESULTS: The postoperative femoral rotation angle (FRA) was -0.72 ± 2.59° in the robot-assisted group and 1.13 ± 2.73° in the conventional group, and were statistically significantly different (p < 0.001).
CONCLUSIONS: This study provides preliminary evidence that the RA-TKA provides more precise control of FRA than CON-TKA, and verifies that tibial rotation angle and combined rotation angle affect postoperative knee pain and functional evaluation.
方法:本研究共纳入了136例连续接受TKA的患者。一半患者接受了RA-TKA,另一半患者接受了同一组外科医生的常规TKA(CON-TKA)。收集相关参数。
结果:机器人辅助组术后股骨旋转角(FRA)为-0.72±2.59°,常规组为1.13±2.73°,差异有统计学意义(p<0.001)。
结论:这项研究提供了初步证据,表明RA-TKA比CON-TKA提供了更精确的FRA控制,并验证了胫骨旋转角度和联合旋转角度对术后膝关节疼痛和功能评价的影响。
