Is there a cure for osteoarthritis?

No. Unfortunately, the answer is no. Hip and knee joints can be replaced if the arthritis is advanced and painful in one of these joints.
Cure unlikely. The saying goes, cure seldom treat often, comfort always! osteoarthritis is a degenerative, wear and tear process which is almost inevitable as we grow older!
No cure. However there are many options for treatment. Medications like anti-inflammatory options like ibuprofen, naproxen, etc. Other options include synvisc/euflexxa injections to help lubricate the joint or even platelet/stem cell therapies as well. Check out regenexx.com.
