Partial Knee Replacement

A Partial Knee Replacement is a surgery to replace only one part of a damaged knee. It can replace either the inside (medial) part, the outside (lateral) part, or the kneecap part of the knee.

Partial knee replacement surgery removes damaged tissue and bone in the knee joint. It is done when Arthritis is present in only part of the knee. The areas are replaced with an artificial implant, called a Prosthetic. The rest of your knee is preserved. Partial knee replacements are most often done with smaller incisions, so there is less recovery time.



The knee joint is divided into 3 compartments:

  1. Medial tibio-femoral (inner half of knee)
  2. Lateral tibio-femoral (outer half of knee)
  3. Patello-femoral (front of the knee)

When is Partial Knee Replacement done? 

Partial knee replacement is done when only a single joint compartment is affected by the loss of cartilage/ arthritis. Most commonly seen in a medial tibio-femoral compartment(inner half of knee).
