Inlay autogeneic bone grafting of tibial defects in primary total knee arthroplasty

Reinforcement of the proximal tibia with autogeneic bone grafts preserves an area of subchondral bone essential for optimal thickness of cement and fixation of the implants. Bone grafts reduce the need for custom implants and may prevent fragmentation of large amounts of eccentrically placed methylmethacrylate and implant failure.
