Knee replacement

Partial knee replacement

Partial knee replacement is suitable in advanced arthritis of a single part of the knee joint. This is most commonly the inner (medial) part of the knee, but can be the outer (lateral) or under the kneecap (patellofemoral) joint. When you have single compartment advanced arthritis and a knee replacement is considered appropriate, the decision is between partial and total knee replacements. There are pros and cons to both of these options. It is important that your surgeon asks what is important to you in order to advise the best option. Briefly, there is evidence that a partial knee replacement will result in a better range of movement in the knee, you are more likely to return to work and activities more quickly and you are less likely to suffer a major medical complication from surgery. In one big recent trial early satisfaction scores were better with partial knee replacement (how happy you were overall). Pain and function scores between partial and total knee replacement are similar. However, the chance of needing your knee replacement revised (the old one removed and a new one put in its place) is higher with partial knee replacement. This will be discussed with you in detail once a thorough examination and investigations are performed. That way, you are fully informed to make the right choice for you.

Total knee replacement

In patients with widespread advanced arthritis in the knee, total knee replacement is a good treatment option.

This procedure replaces the worn surfaces of the joint with artificial surfaces, and in doing so, relieves pain, swelling and stiffness, improves range of movement and function and corrects alignment.

It is a very successful treatment for the majority of patients and relieves the severe pain that many people experience with advanced arthritis. The decision to undergo any form of replacement surgery should be based around your quality of life; surgery is usually considered the last resort option, particularly when other treatment is not adequate or is no longer beneficial, thus leading to deterioration in quality of life.

Non-operative treatments include but are not limited to, physiotherapy, analgesia, cortisone injections, joint supplements and weight loss.
