KNEE REPLACEMENT

KNEE REPLACEMENT


Osteoarthritis of the knee is the commonest cause for knee replacement. Rheumatoid arthritis will have a similar effect on the knees, but to a lesser extent. The disease process will damage inner lining of the bone inside the joint, changing its smooth surface to a very rough uneven one. This deranges weight transmission across the joint. The knees will look like the pictures below at the end. The knee will be painful, walking will be difficult and legs will be deformed

Can not the medication cure this?

Never ever. In fact, if your knees already look like this, I would say it is too late that you should get them replaced. There are many expensive so called cartilage growing tablets, oils, milk powders, pastes and injections which are extensively marketed and advertised in newspapers, television and other media. None of them will help you. You may have realized this if you have already used these fake products. No one should wait until your legs look like this.

Other anti-inflammatory medication will help to reduce joint swelling and relieve pain as long as the medication is taken. Pain will come back when the action of the drug is not available.

What about injections ? any help ?

This is again of temporary help only. It will not give a cure. PRP injection may help at a very early stage of the disease. When it comes to moderate to severe arthritis, it has a little help.
