Introduction. In the setting of periprosthetic joint infection, the complete removal of implants and cement can be challenging with well-fixed, cemented implants about the knee. This can get especially complex in the setting of long cemented femoral stems. Osteotomies are well described in the proximal femur and tibia for removal of implants and cement. There is little information available on distal femoral osteotomies to facilitate knee implant and retained cement removal. Methods. We describe a novel anterolateral oblique distal femoral osteotomy for the removal of well-fixed, cemented components during resection knee arthroplasty that preserves vascularity to the osteotomized segment. Cadaveric anatomic vascular injection studies were performed to document vascularity of the osteotomized segment. Clinical examples, and results will be presented. Results. Anatomic vascular studies documented preserved vascularity to the osteotomized segment. In two patients intramedullary infected implant and cement was completely removed. At reimplantation and final followup the osteotomy was radiographically healed, implants well fixed, and no recurrent infections were noted. Conclusions. This osteotomy appears to be useful when removing well fixed, cemented femoral components during periprosthetic infection. Vascularity and union was preserved and obtained in all patients.
