Q: I am 57 and my knee is locking on me sometimes or gets stiff on me. What can I do? – L. Pratt
A: There could be many causes for your stiff knee and just as many remedies. Osteoarthritis is the most common form of arthritis. It is often called wear-and-tear arthritis because it comes with the aging process. You can take glucosamine and chondroitin because you may have osteoarthritis.
