A partial knee replacement is 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. Surgery to replace the whole knee joint is called total knee replacement.Partial knee replacement surgery removes damaged tissue and bone in the knee joint.

A partial knee replacement is an alternative to total knee replacement for some patients with osteoarthritis of the knee. This surgery can be done when the damage is confined to a particular compartment of the knee.In the past, partial knee replacement was reserved for older patients who were involved in few activities. Now, partial knee replacement is often preferred in the younger population as their recovery is quicker and often with much less pain. About 50% to 60% of patients with arthritic knees are estimated to be eligible for partial knee replacement.

What is Knee Replacement Revision Surgery?

Although today’s implants are designed to last many years, it’s possible  Knee Replacement Statisticsthat at some point in the future—typically 15 to 20 years or more—your prosthetic will break or wear out. If you are overweight or you engage in high impact activities such as running or court sports, the device may fail sooner. When a knee replacement no longer functions correctly, revision surgery is often required. During this procedure, a surgeon replaces the old device with a new one.

When do you need revision knee surgery and what are the signs?

A failed knee implant is usually indicated by an increase in pain or a decrease in knee function. Persistent pain and swelling can indicate loosening, wear, or infection, and the location of the pain can be all over the knee (generalized) or in one particular area (localized).The decline in knee function may result in a limp, stiffness, or instability. Patients who demonstrate these symptoms and signs may require revision joint surgery.

What happens during surgery?

Most revision total knee replacements take longer to perform than primary procedures (about two to three hours). The first step is removal of the implant. If there has been significant bone loss, bone grafts may be required to fill the voids. Bone grafts can be either autograft (your own bone taken from another site of your body) or an allograft (bone tissue from another person obtained from a bone bank). In some cases, metal wedges, wires or screws may be used to strengthen the bone. Finally, specialized revision knee implants are inserted. Temporary drains are usually placed to collect any fluids or blood that may remain after surgery.

What about after surgery?

Recovery time after revision knee surgery varies; some patients take longer to recover. In most cases, physical therapy will be initiated within 24 hours of the procedure. In some cases, protective weight bearing, such as Partial Weight Bearing (PWB) or Toe Touch Weight Bearing (TTWB), is needed to promote bone healing. Therapy will usually continue for up to three months following the surgery.

What should you expect after surgery?

Greater than 90% of patients who undergo revision procedures can expect to have good to excellent results. Although expected outcomes include pain relief with increased stability and function, complete pain relief and restoration of function is not always possible. Up to 20% of patients may still experience some pain following revision knee surgery.
