I have a question about unicompartmental knee replacement

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.

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.

How much does a partial knee replacement cost?
