Abstract
A two-thirds prosthetic arthroplasty having a trochlear groove, a patello-femoral component, and either a lateral condyle or a medial condyle. The arthroplasty may be configured to be a prosthetic for either a right or left knee. The condyle and patello-femoral component are separated by a modified intercondylar notch that is blended to avoid protrusions or sharp angles. The prosthetic arthroplasty is inserted after preoperative MRI mapping of articular cartilage damage. The prosthetic arthroplasty may be cemented during surgery and the two-thirds design of the present invention obviates the problem of cement retrieval from remote parts of the prosthesis.
