Fig. 4From: A case of bilateral revision total knee arthroplasty using distal femoral allograft–prosthesis composite and femoral head allografting at the tibial site with a varus-valgus constrained prosthesis: ten-year follow upSurgical procedures on the femoral side. a Step-cut prepared distal femoral allografts and prepared composite distal femoral allograft with LCCK implant, using APC (allograft–prosthesis composite). b After extensive removal of the hypertrophic synovium of the left knee, extensive bone loss of the distal femur was observed and APC was fixed to the host bone with a Dall-Miles cable. c The right knee was similar operative finding to that of the left knee and APC was fixed to the host bone in the same way as the left kneeBack to article page
