Articular Cartilage Tear in Knee


My brother has suffered an articular cartilage tear in his knee, and his doctor and I have been discussing what all options he has for treatment. I’ve been pushing for him to do stem cell injections wether or not the doctor is going to suture repair the cartilage, but he only wants to consider it if he doesn’t have to do that. Has anyone here had experience with stem cell work? How effective was it for you? How similar was your injury?

Thanks ahead of time.
