Peroneal nerve damage can occur during total knee arthroplasty because of indirect or direct injury. The potential for direct laceration injury exists when performing the "pie crust" lateral soft-tissue release in a valgus knee. To assess this risk, the axial, magnetic resonance images of 60 adult knees were evaluated. The distance from the peroneal nerve to the tibia was measured at the level of the standard tibial resection. At this level, the lateral gastrocnemius muscle is interposed between the capsule and the nerve. The mean nerve to bone distance was 1.49 cm (0.91-2.18 cm). These results suggest that the peroneal nerve is adequately protected at the posterolateral corner of the knee but that the "pie crust" release should be performed carefully.
在全膝关节置换术中，由于间接或直接损伤，腓总神经可能会受损。在进行外翻膝关节的“扇形”外侧软组织松解时，存在直接撕裂损伤的可能性。为评估这种风险，对60例成人膝关节的轴向磁共振图像进行了评估。在标准胫骨截骨水平测量腓总神经到胫骨的距离。在此水平，外侧腓肠肌介于关节囊和神经之间。神经到骨的平均距离为1.49厘米（0.91 - 2.18厘米）。这些结果表明，腓总神经在膝关节后外侧角得到了充分保护，但“扇形”松解操作仍应谨慎进行。
