Abstract

BACKGROUND

The purpose of this study was to compare early clinical and patient-reported outcomes between robotic assisted (RA) and computer navigation (CN) total knee arthroplasty (TKA).

METHODS

One hundred and fifty patients were enrolled in this prospective, single-surgeon, cohort study, with 75 patients each receiving CN-TKA or RA-TKA in a consecutive series. There were no differences in patient age ( = .34) or body mass index ( = .09), but a higher proportion of males underwent RA-TKA ( = .03). We recorded hospital knee pain, analgesic usage, length of hospital stay, range of motion, and patient-reported outcome measures postoperatively for both patient cohorts.

RESULTS

Hospital length of stay was shorter for the RA-TKA patients ( < .001). RA-TKA patients showed improved range of motion ( < .001) and decreased pain scores ( = .006) on day 1. Subsequent days showed no significant differences. Narcotic usage was lower for the RA-TKA group on day 2 postoperatively ( = .03) and onwards. Total morphine equivalent dose was also significantly lower for the RA-TKA than for the CN-TKA group ( < .001). There was no difference in Forgotten Joint Score ( = .24) or Oxford Knee Score ( = .51) between groups at 2 years postoperatively.

CONCLUSION

The use of RA-TKA demonstrated reduced postoperative analgesia usage and length of stay. There were no differences seen between CN-TKA and RA-TKA with respect to clinical outcomes at 2 years after surgery.

摘要

背景

本研究的目的是比较机器人辅助（RA）和计算机导航（CN）全膝关节置换术（TKA）的早期临床和患者报告结局。

方法

150例患者纳入了这项前瞻性、单术者队列研究，连续系列中每组75例患者分别接受CN-TKA或RA-TKA。患者年龄（P = 0.34）或体重指数（P = 0.09）无差异，但接受RA-TKA的男性比例更高（P = 0.03）。我们记录了两个患者队列术后的膝关节疼痛、镇痛药物使用情况、住院时间、活动范围以及患者报告的结局指标。

结果

RA-TKA患者的住院时间较短（P < 0.001）。RA-TKA患者在术后第1天活动范围改善（P < 0.001）且疼痛评分降低（P = 0.006）。随后几天无显著差异。术后第2天及以后，RA-TKA组的麻醉药物使用量较低（P = 0.03）。RA-TKA组的总吗啡当量剂量也显著低于CN-TKA组（P < 0.001）。术后2年时，两组间的遗忘关节评分（P = 0.24）或牛津膝关节评分（P = 0.51）无差异。
