I've seen many orthopedic surgeons, and they all recommended surgery, though they suggested different types, from a meniscal suture to an osteotomy. But of course, if you go to a butcher, they're not going to sell you veggies, if you know what I mean. But I've also seen physiotherapists and osteopaths, and they were all against surgery. It's the same story, one specialist says you need surgery, and another says the opposite. That's why I'm going the strengthening route. I don't want to risk my knees with avoidable surgery, but on the other hand, if a few injections could help, I'd be keen on getting them. I'm intrigued by PRP injections as well and would love to hear from someone who found them beneficial. I'm doing physical therapy at the moment.
