What Is Partial Knee Replacement Surgery?

Partial knee replacement is a procedure that removes the bone and cartilage of the knee that has been damaged due to arthritis and replaces them with metal and plastic components.

These components mimic the anatomy and function of a healthy knee so that you can return to activities without the pain caused by arthritis.

About Partial Knee Replacement Surgery


This procedure differs from a total knee replacement in that only one side (also known as a “compartment”) of the knee joint has been affected by arthritis.

Therefore, only that compartment needs to be replaced and the undamaged portion of the knee can remain intact.

The procedure is one of the most effective in orthopedic surgery because it dramatically decreases knee pain and improves a patient’s quality of life.

The Board Certified Orthopedic Knee Surgeons at OrthoNeuro have performed thousands of partial knee replacements and are experts in this procedure using the latest advancements in surgical techniques.

A partial knee replacement may be recommended to treat severe osteoarthritis, rheumatoid arthritis, and post-traumatic arthritis that does not respond to non-surgical treatment when the damage is limited to one compartment of the knee joint.

How a Partial Knee Replacement Is Performed

At OrthoNeuro, a partial knee replacement can be performed as an outpatient or inpatient procedure based on what you and your OrthoNeuro surgeon feel are best for you.

During the procedure:


  1. Incision and joint exposure: An incision is made below, around, and above the patella (knee cap). Muscles and soft tissues are retracted.
  2. Joint preparation: Damaged bone and cartilage are carefully removed. Trial implants are tested until the perfect size is found.
  3. Implants: Perfectly sized implants are placed and cemented over the precisely cut knee bones.

The incision is carefully closed to prevent infection and ensure proper healing.

Total procedure time is usually less than 2 hours and physical therapy is typically started on the day of surgery to expedite recovery.
