Will collagen work for knees when it is bone on bone?

The product you are asking about is SynVisc. This product is injected into knee joints, and acts as a cushioning synovial fluid-like polymer that diminishes the pain of bone on bone contact. Orthopedic surgeons are the physicians who are knowlegeable about these products.

Collagen is (was) used as skin fillers for wrinkles and facial lines, and has absolutely no use for the medical condition you are describing.

Consult with a board-certified orthopedic surgeon who is experienced in knee surgery and total knee replacement, whihc is what you likely require. He or she will know all about SynVisc.

In today's time, I have read that hyaluronic acids, different from the ones injected in the skin, have been injected in the knees but you would have to check with an orthopedist.

Thanks for the question.

Contact a board certified orthopedic surgeon to address this question. This falls out of the realm of plastic or aesthetic surgery.

This procedure is typically done by an orthopedic surgeon not for cosmetic purposes and the question better addressed to such a physician.
