How can i build or repair cartilage in joints?

No*: There is no current way to regrow hyaline cartilage (the type that is on joint surfaces). When joint cartilage is damaged, it is replaced with less smooth cartilage. An arthroscopy can be performed with tools used to help improve cartilage. The suppliment glucosamine chondroitin can help in some cases. There is also an injectable joint fluid that can help. Research may help find new ways.
