Hi, Thanks for your query. For osteoarthritis, weight reduction is the main treatment along with medicines to decrease pain like NSAID s - paracetamol, aceclofenac etc., Life style modifications like avoiding sitting cross legged, squatting, using indian type toilets will decrease the rate of progression of osteoarthritis. Exercises like quadriceps strengthening, swimming, straight leg raising will help in improving the muscle strength around the knee and will help in decreasing pain. Hyaluronic acid injections given into the joint (especially large joints like knee joint) in prescribed dosages will give good short term pain relief in arthritic joints ranging from 1-2 years. You can take them after consulting an orthopaedic surgeon. Many of my patients do get relief by yoga - pranayama and sudarshan kriya. You can start with these under the guidance of an expert. In early stages exercises, medicines ,joint supplements & intra articular injections are helpful & may revert the changes but in late cases joint replacement is only option. I do hope that you have found something helpful and I will be glad to answer any further query. Take care
