title: Anterior distal femoral osteotomy for removal of long femoral stems in revision knee arthroplasty.
abstract: Osteotomies of the proximal femur and proximal tibia in revision arthroplasty are well described while guidelines for distal femoral osteotomy are limited. Femoral stems are used with increasing frequency for fixation of revision components in knee arthroplasty and their removal is technically challenging particularly in the setting of infection. We describe a technique of anterior distal femoral osteotomy for revision knee arthroplasty to assist with removal of well-fixed long stemmed cemented or porous femoral components, as well as debridement of infection while preserving bone stock and soft tissue attachments.
