Patent ID: 6916341

Claim:
A device for bicompartmental arthroplasty of the knee comprising: a monolithically formed medial, but not lateral, femoral prosthesis component having a first internal surface configured to be secured to a surgically prepared medial compartment of a distal end of a patient's femur and a second exterior convex curved surface positioned and configured to replicate a medial femoral condyle; said medial femoral prosthesis component also having a concave trochlea surface positioned and configured to articulate with the patella; and a unicondyle medial tibial prosthesis component having a first interior surface configured to be secured to a surgically prepared medial compartment of a proximal end of the patent's tibia and a second concave curved exterior surface configured to receive the second convex curved surface of said medial femoral prosthesis component to permit pivotal articulation between said medial femoral prosthesis component and said medial tibial prosthesis component, said pivotal articulation approximating the articulation of a healthy knee joint.
