Abstract
The invention is in the field of orthopedic implants. More specifically, the invention relates to a revision knee implant. The implant of the invention includes a femoral component, a bushing and a locking member and is configured for positioning, in use, in the natural knee joint. The implant also may include a femoral stem. The femoral component has spaced apart condylar portions defining an intercondylar region. The intercondylar region includes elongate engagement rails that extend in the anterior-posterior direction. The bushing slides along the length of the engagement rails. The locking member locks the bushing in a desired position in the anterior-posterior direction of the engagement surface. The femoral stem is configured for insertion, in use, into the femoral canal, and is also configured for secure attachment to the bushing at an angle in substantial alignment with the valgus angle of the patient. When a femoral stem is in position in the bushing, the locking member is captured between the femoral component and the femoral stem.
