Total knee arthroplasty is a successful surgery for the majority of patients with osteoarthrosis of the knee. Approximately 5% of patients undergoing total knee arthroplasty experience loss of motion or arthrofibrosis. Manipulation under anesthesia (MUA) is generally indicated for patients who do not achieve >90° of flexion by 6-12 weeks postoperatively. Complications from MUA are rare but can be devastating. We describe a novel technique for MUA with no reported major complications in our review of 78 patients. The average flexion improved from 80.0 (±3.8) before manipulation to 115.4 (±2.1) after manipulation. There were no major complications including fracture or extensor mechanism injury.
全膝关节置换术对大多数膝关节骨关节炎患者来说是一种成功的手术。接受全膝关节置换术的患者中约有5%会出现活动度丧失或关节纤维性强直。对于术后6至12周仍未达到90°以上屈曲度的患者,通常会采用麻醉下手法松解(MUA)。MUA的并发症很少见,但可能是灾难性的。在我们对78例患者的回顾中,我们描述了一种MUA的新技术,未报告有重大并发症。平均屈曲度从手法松解前的80.0(±3.8)改善到手法松解后的115.4(±2.1)。没有包括骨折或伸肌机制损伤在内的重大并发症。
