Well, autograft OATS is kind of like robbing Peter to pay Paul. The donor site is chosen because it is not weight-bearing and so lack of cartilage there is supposed to be less of a problem.
That being said, though, you basically create an area of arthritis (no cartilage left) in order to fill in the other defect.
Due to that, you can get pain, catching, etc. at the donor site. My biggest post-OATS complaint is actually my donor site. I have trouble walking up and down stairs now and I get painful popping over the donor site from time to time. Overall though, it's much better than before the OATS.
