Partial Knee Replacement
A partial knee replacement is a minimally invasive surgical option that replaces only the damaged portion of the knee, helping to relieve pain and restore mobility while preserving as much of the natural knee as possible.
Partial knee replacement, or unicompartmental knee replacement, is a surgical option for patients with advanced osteoarthritis affecting only one part of the knee. Unlike total knee replacement, this procedure resurfaces only the damaged area of the knee with metal and plastic components, preserving healthy bone, cartilage, and ligaments for a more natural joint function.
This procedure is suitable for both younger and older patients with osteoarthritis limited to one compartment of the knee who have not found relief with nonsurgical treatments. About 30% of people with arthritic knees are estimated to be eligible for partial knee replacement.
Partial knee replacement offers several advantages over total knee replacement, including quicker recovery, less pain after surgery, minimal blood loss, and a lower risk of complications like infection or blood clots. Additionally, because healthy structures of the knee are preserved, many patients experience better functionality in the long term and report that their knee feels more natural and bends more easily after the procedure.
Partial knee replacement has demonstrated excellent medium- and long-term success for both younger and older patients, helping them return to daily activities with less pain and improved mobility.
