What Causes Osteoarthritis?

Video Transcript

Hello my name is Dr. Susan Jewell and behalf of expert village today I am going to talk to you about the subject of osteoarthritis. Which is disease of the bones particularly the joints. Now how does is happen. How does arthritis happen, what what actually happens to the bone? Well, it’s not the bone that is effected it's actually the capsules or the cartilage that embeds the bone. For, example here's a look at the joint and here's say this is the knee joint cause arthritis effects a lot of the knees most of the time. So in the normal healthy person the knee joint is with the two bones the upper bone and the lower bone is encapsulated by this cartilage material here and that's nice and thick and it gives a padding to decrease friction and lubrication of the two joints when you're moving and you're moving your knee joints together. So, that’s what happens but over time the deterioration of this cartilage padding on the bones deteriorates and is lost, also by diet, ageism is a major factor, so that you are only left with a little bit of the cartilage left and what happens is then, is then, what results in the lost of the cartilage of padding is that bones actually touch each other and then friction, the friction of the two bones without the padding will give you the pain and the inflammation. So, in the next series of clips I am going to talk to you how to deal with pain and inflammation caused by arthritis.
