PARTIAL KNEE REPLACEMENT
If you suffer from constant knee pain caused by osteoarthritis that’s confined to one area of your knee, partial knee replacement surgery may relieve your pain and help you regain your active life. Partial knee replacement surgery, also called unicompartmental arthroplasty, repairs the diseased area of the knee, saving as much of your natural knee as possible.
Partial knee replacement uses a smaller incision than a total knee replacement procedure so your knee joint suffers less stress. Minimizing joint stress shortens recovery time, reduces post-surgery pain and can help you regain your active lifestyle sooner. Watch this video to learn more about partial knee replacement surgery.
This procedure may not be suitable for people with inflammatory arthritis, very bad knee stiffness or ligament damage.

Questions and Answers about Partial Knee Replacement Surgery
What is osteoarthritis?
Osteoarthritis is a form of arthritis and a degenerative joint disease that causes cartilage to break down, removing the buffer between bones. This may cause pain during normal daily activities and can eventually cause loss of motion and poor alignment of the knees.
How will I benefit from this procedure?
Partial knee replacement can help you reclaim an active life by reducing your knee pain, increasing your mobility and restoring your range of motion. Surgery is a good alternative when non-surgical treatments have failed to restore the health of your knee joint.
Will I be able to resume my normal activities after surgery?
Your recovery will depend on your overall health and the success of your rehabilitation. Most people can resume light activities, such as walking and driving, within three weeks and normal activity within six weeks. Your commitment and cooperation are vital to a successful recovery. Following your orthopedist’s advice and adhering to your rehabilitation plan will increase your odds of resuming normal activities and reducing recovery time.
How long will my knee implant last?
Medical research shows most of the latest implants last an average of 10-15 years depending on your age and
What are the risks of this surgery?
Partial knee replacement is generally safe but, as with any surgery, complications can occur. Possible problems that could arise from this surgery include:
Blood clots can form in your leg veins as a result of decreased movement of your leg after surgery or injury to your veins during the procedure. Orthopedists usually prescribe blood-thinning medications after surgery to prevent clots from forming. Exercises that increase blood flow through your leg veins, such as walking, can also reduce the risk of clots.
Infections can occur at the site of your incision and in the tissues near your new implant. Most infections are treated with antibiotics, but a major infection near your new implant may require surgery to replace the knee joint.
Implant problems – New materials are helping implants last longer, but your knee joint may eventually wear out or the components may loosen. If you have partial knee replacement surgery when you're relatively young, you may need a total knee replacement within your lifetime.
Neurovascular injury–The nerves or blood vessels in your knee may be injured during surgery. A major blood vessel injury could require surgical repair.
