Unicompartmental knee replacement

Unicompartmental knee replacement

If knee pain is affecting your sleep, work or exercise, a partial or unicompartmental knee replacement replaces only part of your knee with an artificial joint and is less invasive than a total knee replacement.

FAQs

What is a unicompartmental knee replacement? +

A unicompartmental knee replacement is a partial knee replacement. It’s an option if osteoarthritis of the knee has only affected part (the inside/medial or outside/lateral) ‘compartment’ of your knee.

The revision rates are higher in partial knee replacement surgery compared to a total knee replacement.

What happens during a partial knee replacement? +

On the day of your operation your Consultant and Anaesthetist will answer any questions you may have.

During a partial knee replacement procedure, the damaged compartment will be replaced with a prosthesis leaving behind the healthy bone and cartilage. In most cases it means you’ll recover more quickly and experience less pain following surgery.

What should I expect after partial knee replacement surgery? +

After your operation, we’ll move you to our recovery room for observation until you’re ready to return to the ward where you’ll be looked after by our experienced nursing team.
