A partial knee replacement -- also called a unicompartmental knee replacement -- involves putting an implant on just
one side of the knee, rather than over the entire surface of the knee joint. Think of the knee as having three compartments:
an inside, outside, and a front compartment for the kneecap. Most frequently, it is the inside compartment that becomes arthritic.
A unicompartmental knee replacement is performed if part of the knee joint is damaged by arthritis and the other compartments have
healthy, normal cartilage. By retaining undamaged parts of the knee, the joint may bend better and function more naturally.
This Unicompartmental Knee System is offered in two designs, inlay and onlay. Your surgeon will determine which implant design would be best suited for your knee.
