Partial knee replacements, also known as unicompartmental knee replacements, are performed when only some structures in the natural joint need to be replaced. With a partial knee replacement, the natural joint is preserved while problematic bones and tissues are replaced. Candidates for partial knee replacement generally return to an active, pain-free lifestyle that lasts for many years without the need for additional operations.
Did You Know?
Partial knee replacements are less invasive than total knee replacement surgery. This ultimately means that you will experience less blood loss during surgery, a shorter recovery period, and less postoperative pain.
Frequently Asked Questions:
Am I a candidate for a partial knee replacement?
You may be an ideal candidate for a partial knee replacement if you have an injury or degenerative disease that only affects one part of your knee joint, such as medial or lateral osteoarthritis. However, if more than one compartment of your knee is affected, then a total knee replacement may be better. Additionally, those with inflammatory arthritis, significant knee stiffness, and ligament damage may not be an ideal candidate for a partial knee replacement. To determine if you are an ideal candidate for a particular knee replacement, schedule a consultation with one of our orthopedic surgeons today.
What should I expect during a partial knee replacement?
When having a partial knee replacement, you can expect an inpatient surgery performed under general anesthesia. Your surgeon will begin by making a small incision in your knee to remove any diseased or damaged tissue from the joint. Then a partial prosthetic will be placed to replace any tissue that was removed. The incision will then be stitched and bandaged. In most cases, a partial knee replacement takes about 1-2 hours or less, however you will need to spend an additional 2 hours in the recovery room directly following surgery.
What should I expect after a partial knee replacement?
After your partial knee replacement, you can expect to stay in the hospital for about two days so that your surgeon can monitor the start of your recovery. During your recovery period, you can expect to take pain medications and partake in physical therapy to help regain mobility and strength in your knee joint. In most cases, you will be able to resume most of your usual activities approximately six weeks after surgery.
