Neuropathy after total knee arthroplasty (TKA) can cause significant morbidity but is inconsistently reported.
We reviewed the clinical, electrodiagnostic and perioperative features of all patients who underwent primary TKA at our institution and developed a new neuropathy within 8 weeks postoperatively.
Fifty-four cases were identified (incidence 0.37% [95% confidence interval, 0.28-0.49]) affecting the following nerve(s): peroneal (37), sciatic (11), ulnar (2), tibial (2), sural (1), and lumbosacral plexus (1). In all cases with follow-up data, motor recovery typically occurred within 1 year and was complete or near-complete.
Post-TKA neuropathy is uncommon, typically does not require intervention and usually resolves within 1 year. Post-TKA neuropathy most often affects the nerves surgically at risk. Anesthesia type does not correlate with post-TKA neuropathy. An inflammatory etiology for post-TKA neuropathy is rare but should be considered in specific cases. Muscle Nerve 59:679-682, 2019.
全膝关节置换术后神经病变可导致显著的发病率，但报道不一致。
我们回顾了在我院接受初次全膝关节置换术的所有患者的临床、电诊断和围手术期特征，并在术后 8 周内新出现了神经病变。
共发现 54 例（发生率 0.37%[95%置信区间，0.28-0.49%]），影响以下神经：腓总神经（37 例）、坐骨神经（11 例）、尺神经（2 例）、胫神经（2 例）、腓肠神经（1 例）和腰骶丛（1 例）。在所有有随访数据的病例中，运动功能通常在 1 年内恢复，完全或接近完全恢复。
全膝关节置换术后神经病变并不常见，通常不需要干预，通常在 1 年内恢复。全膝关节置换术后神经病变最常影响手术风险的神经。麻醉类型与全膝关节置换术后神经病变无关。全膝关节置换术后神经病变的炎症病因很少见，但在特定情况下应考虑这种病因。肌肉神经 59:679-682,2019。
