Unicondylar knee replacement is also known as unicompartmental knee replacement. It is considered to be a less invasive procedure than traditional total knee replacement. This replaces only the most damaged parts of the knee and is often used on arthritis patients. The advantages for the patient include less scarring, a better range of motion, and shorter recovery times. 

This procedure is often chosen by younger, more active patients who aren’t prepared to undergo a total knee replacement. It is also used by patients with arthritis that is limited to only one part of the knee. 

The Procedure

The Oxford unicondylar knee replacement involves making a small incision near the damaged area. Small pieces of bone are removed from the damaged area of the femur (thigh bone) and tibia (front lower leg bone). Those pieces are replaced with the Oxford Partial Knee implant, which is made of metal. A plastic insert then allows for smooth movement of the joint. 

Other parts of the knee aren’t touched during this procedure, depending on the amount of damage. Less bone loss leads to a greater range of motion after surgery. Most patients recover fully within a month and can still participate in low-impact sports and other light activities.
