Some cartilage loss, enough to make me limp a little. There was still a fair amount of cartilage there and a good space between the bones for it to fill in. From what they've told me if you're down to bone-on-bone then PRP won't help. It would definitely help a torn meniscus - I'd get it done for that in a heartbeat!
Btw, all those older celebs and athletes you see who seem to move so well despite advanced age? Yep: PRP. They've been getting it done in many of their joints for decades. They're probably on a big cocktail of drugs, too, but they've been doing PRP for years so their joints stay healthy and don't deteriorate. Must be nice, eh?
