Partial knee replacement can be done when damage to a knee from osteoarthritis is confined to one compartment. Only the damaged part of the knee is replaced. Partial knee replacement is being done for more young active people thanks to the quick and usually painless recovery.
A partial knee replacement is an alternative to total knee replacement for some people with osteoarthritis of the knee. This surgery can be done when the damage is confined to a particular compartment of the knee. In a partial knee replacement, only the damaged part of the knee cartilage is replaced with a prosthesis.
Once partial knee replacement was reserved for older patients who were involved in few activities. Today a partial knee replacement is often done in younger people as their recovery is quicker and usually less painful. About 5% to 6% of people with arthritic knees are estimated to be eligible for partial knee replacement.
