MODULAR FEMORAL COMPONENTS FOR KNEE ARTHROPLASTY

摘要

A femoral knee prosthesis system for resurfacing a resected articular surface at the distal end of a femur includes a femoral component adapted to mate with the resected articular surface; and an attachment member. The interior surface of the femoral component is configured to connect to the first attachment member when the femoral component is mated on the resected articular surface of the femur and when the first attachment member is passed through the medial side or the lateral side of the resected articular surface. The femoral component is available in one-piece and two-piece systems. Mating femoral components (e.g., tapered or with lips that interlock with grooves) are also disclosed.
