Biological knee replacement

 Tissue engineering techniques are improving now to the point where larger areas of joint damage can be treated. End-stage arthritis with severe pain is treated with knee replacement surgery where either part or whole of the joint is replaced with an artificial material. Joint replacement is a very successful operation in those with a relatively low level of function.

However, in individuals who are very active, knee replacements are less successful and preserving one’s joint is more preferable.

Materials, along with cellular technologies, now enable us to literally ‘grow’ a new joint instead of replacing it. Bone marrow cells (these are rich in stem cells) are placed on an artificial ‘scaffold’ which encourages the growth of new cartilage. This scaffold is implanted onto the damaged areas allowing patients to be pain free and function normally.

This is an example of a patient in their 20’s who had severe damage to all areas of the knee joint. He was in pain and could not run and work in his job as a football coach. Following surgery and rehabilitation, he resumed football coaching.

The image below shows the knee joint with large areas of cartilage loss. Microfracture has been performed (perforations in the bone).

I want to thank Mr. Datta for taking such good care of me during both hip replacement procedures. It was my first major surgery and he helped calm my nerves. Both surgeries were successful and the after care was excellent. I am now completely pain free and able to do things I was not able to do for a number of years.

I must say my overall experience at Spire under Mr Datta was first class and I am very grateful to all involved

My care and treatment has been excellent. From my first consultation through to my surgery, I have been kept well informed and have had all the information I’ve needed to ensure the surgery went well and that I make a speedy recovery. I would highly recommend Mr Datta.

I had a total knee replacement done and had the best care. Yes did experience a long wait to go to surgery but that's expected in most hospitals. Was in for 3 days and couldn't fault the care, nurses and cleanliness of the hospital. Lovely food. One nurse in particular always managed to make me smile
