We evaluated the efficacy of periarticular infiltration of corticosteroid, opioid, and a local anesthetic by comparing pain scores, knee flexion, and quadriceps function on the day of surgery, first postoperative day, day of discharge, and 2 and 4 weeks after surgery between the infiltrated and the noninfiltrated knee in 40 patients undergoing simultaneous bilateral computer-assisted total knee arthroplasty who were randomized to receive the injection in the right or left knee. In comparison to the noninfiltrated side, the infiltrated knee showed significantly lower pain scores, significantly greater active flexion up to 4 weeks, and superior quadriceps recovery up to 2 weeks after surgery. This simple and inexpensive technique can significantly reduce pain and hasten functional recovery in the first month after total knee arthroplasty.
我们评估了关节周围注射皮质类固醇、阿片类药物和局部麻醉剂的疗效，将 40 例行双侧计算机辅助全膝关节置换术的患者随机分为右膝或左膝注射组，比较了手术当天、术后第 1 天、出院当天以及术后 2 周和 4 周时两组患者的膝关节疼痛评分、膝关节屈曲度和股四头肌功能。与非注射侧相比，注射侧膝关节疼痛评分明显降低，术后 4 周内主动屈曲度明显增加，术后 2 周内股四头肌恢复更好。这种简单且经济的技术可以显著减轻全膝关节置换术后 1 个月内的疼痛并促进功能恢复。
