Abstract:
[Objective] To explore the causing and prevention factors of peroneal nerve injury after total knee arthroplasty(TKA).[Method] Nine postoperative peroneal-nerve injury in 9 patients were documented in a retrospective review of 2000 consecutive total knee arthroplasties performed at one institution from Jan.1996 to Jun.2007.Six fresh cadaver knees were executed TKA to observe the causing factors of peroneal nerve injury in operation.[Result]The causing factors of the 9(0.45%)patients were not clear.Cadaver knees TKA suggested the dangerous handlings by turns include the belows:①lifting distal femur by encircle dragging may enhance lesion probability of common peroneal nerve.②risk for common peroneal nerve to set Hoffman crook not paralleling longitudinal axis of tibia or posterior the lateral collateral ligament.③excessive straightening knee joint after the prosthesis had been fixed.[Conclusion]Lifting distal femur by encircle dragging should be avoided while peeling posterolateral joint caps and caput laterale musculi gastrocnemii.The location,inserting orientation and depth of Hoffman crook should be taken care of.Hyperextension of the knee should be avoided.
