Partial knee replacement
UNICOMPARTMENTAL KNEE REPLACEMENT
Our leading knee surgeons can treat an arthritic joint with a partial knee replacement — a less invasive procedure
What is a unicompartmental knee replacement?
As partial knee replacement involves a smaller incision, it's a preferred alternative to total knee replacement, causing less damage to the bones. Other benefits are a quicker recovery and less time off work, especially if keyhole surgery (arthroscopy) is used.
The procedure is being used more in younger patients with arthritis, allowing them to keep more of their knee joint.

What happens during a partial knee replacement? icon plus
The procedure happens under general anaesthetic. The operation usually lasts between one and two hours and you will need to spend up to three nights in hospital. -
How to prepare icon plus
Your consultant will explain the procedure to you and answer any questions you may have. Because you'll be having general anaesthetic, they'll let you know how long you should avoid eating and drinking before surgery. Like all procedures, there may be some risks and side effects involved. Your consultant will explain these to you. -
After surgery icon plus
Partial knee replacements are a less invasive surgery than total knee replacement and you can expect to go home within three days. A member of the physiotherapy team will visit you after surgery and get you moving with the help of crutches or a walker. You won't be able to bear weight on your knee for several days.
You will be given medicine to control the pain — usually local anaesthetic and anti-inflammatory medicine. Your consultant will let you know when you can get back to your usual routine, including work or exercise. This is likely to be six weeks after surgery.
