JOINT IMPLANT, ESPECIALLY THE KNEE JOINT

摘要

The invention relates to a joint implant, especially the knee joint, comprising a femoral component, an insert and a tibial component. The femoral component of the knee joint replacement is composed of a shell mould (1) attachable to the distal part of the femur (2), where the reference plane determining the outer and inner shape of the mould (1) is a trimmed, spaced and smoothed surface of the distal part of the patient's femur (2) that accounts for the overall curvature of the knee joint. The outer lateral and antero-posterior dimensions of the shell mould (1) match the specific knee joint of the given patient. The inner surface of the shell mould (1) contains ribs (3), where the ribs lock laterally and longitudinally in grooves created operatively in the distal part of the patient's femur (2). The shell mould (1) is advantageously made from a bio-compatible material.
