Hello,
There is no specific medication or treatment to repair or halt the damaged cartilage in osteoarthritis. The things which you should stay away at this stage are excessive workout or stress and start losing weight. The treatments which are currently available are to reduce the joint pain and to improve and maintain the function of joints. You can even get benefits by taking rest, following a proper diet, exercising, physical therapy and much more. Still, if you are unable to bear the pain, it is recommended to consult your family doctor as he will be well aware of your body and can guide you accordingly.
Thanks & Regards
