Partial Knee Replacement Surgery

When a person has a partial knee replacement, the doctor only resurfaces one or two compartments of the knee. The surgeon spares as much of the healthy tissue and bone as possible, and this may help retain range of motion, encourage more natural function and decrease healing time. However, the other parts of the knee may become arthritic at a later date, and another surgery to resurface those portions of the knee might be required.

Depending on the number of surfaces damaged, there are three general types of partial knee surgery:
Unicompartmental surgery replaces one side (compartment) of the knee.  
Bicompartmental surgery replaces both sides (compartments) of the knee.  
Patellofemoral surgery replaces the end of the thigh bone with a metal piece and resurfaces the back of the kneecap (patella).  

Each of these procedures requires a different prosthesis and surgical technique. For a partial knee replacement, the incision is much smaller than for a total knee replacement and is usually only about 3 to 4 inches. After making the incision, the surgeon will first make sure that the damage can be corrected with a partial procedure. If that’s the case, the damaged parts of the bone are then capped with metal pieces, and a plastic piece is inserted between the two metal components.
