Five patients were treated by operative exploration and decompression of the peroneal nerve for peroneal nerve palsy complicating total knee arthroplasty (TKA). All patients had failed to demonstrate improvement in the peroneal nerve function despite extended conservative care. The procedure was performed five to 45 months after the index TKA. Patients were evaluated and graded preoperatively and postoperatively using the Modified Nerve Palsy Scale of Weber, Daube, and Coventry. All patients demonstrated improved nerve function. Four of five patients had full peroneal nerve recovery. All patients were able to discontinue their ankle-foot orthoses. This is a rare complication of TKA, and when conservative nonoperative measures do not lead to sufficient improvement in nerve function, consideration may be given to operative decompression of the peroneal nerve.
5例因全膝关节置换术（TKA）并发腓总神经麻痹而接受手术探查及腓总神经减压治疗的患者。尽管经过长期保守治疗，所有患者的腓总神经功能均未显示出改善。该手术在初次TKA术后5至45个月进行。术前和术后使用Weber、Daube和Coventry改良神经麻痹量表对患者进行评估和分级。所有患者的神经功能均有改善。5例患者中有4例腓总神经完全恢复。所有患者均能够停用踝足矫形器。这是TKA的一种罕见并发症，当保守的非手术措施不能使神经功能得到充分改善时，可考虑对腓总神经进行手术减压。
