 Hi, I'm Dr. Yogesh Kamat, I'm a specialist hip and knee surgeon and I'd like to talk to you a little bit about cartilage regeneration. Now, who hasn't heard of arthritis? It is something which is there in every family, either a friend or a relative. Now, it is common that senior citizens get arthritis and many, many people are going towards joint replacement surgery. However, when the average 40 or 50 year old working person gets rid of joint pain, does that mean that they are proceeding towards joint replacement surgery? There is a whole range of symptoms and structural problems under the wide group of arthritis. It is all about picking arthritic changes relatively early. Particularly in young people, when I say young, I'm talking about everybody who's not a senior citizen. Particularly in these, if they've had pains after some injury, there could be lesions which are not really detectable in x-rays and lesions in the surface of the joint that is the cartilage surface which are amenable to treatment by which joint cartilage can be regenerated. Now, there are various techniques and these have been developed in the last few years. They are not alternatives to joint replacement but options for people who have early damage in their joints. Now, this needs to be looked at rather than being lived with. You could feel free to consult a specialist in these procedures and there are a few in India where we can get specific MRIs which tells us about the conditions of cartilage in the joint. There could be a lot of structures in the joint which can get damaged and can be made to regenerate by specific techniques. Some of you might have heard about stem cells. Now, it's not just stem cells but we can use our bone marrow. We can use specific techniques where cartilage can be taken from areas where it is not essential and be made to regenerate outside the body and re-implanted back in the right conditions. These need to be seen by a specialist and can definitely work towards making your joint normal.
