Periprosthetic femoral fracture after a well-fixed revision total knee arthroplasty treated with in situ effective lengthening of prosthesis.
The increasing number of total knee arthroplasties implies a greater likelihood of periprosthetic fractures and need for successful treatment options. We report a case where in situ effective lengthening of the stem of a well-fixed indwelling prosthesis by a custom-made intramedullary nail with taper-lock coupling provided a successful alternative to the established internal fixation techniques involving prosthesis exchange. We believe that effective lengthening of indwelling prosthesis by a custom-made intramedullary nail is an effective option for treating periprosthetic femoral fractures in selected cases, where an attempt of removing well-fixed implant would result in unacceptable bone loss at the joint level.
