He does have luxating patella, in both legs. In his left it is way out of place, and in his right it is half way out of place.
Another complication ... he is pidgeon toed, so his lower leg bones curve! They are nowhere near straight! So the surgery would be very complicated where his bones aren't straight. It's doable but the success rate is very low. That and the fact that his legs aren't bothering him right now. The vet said that smaller dogs, some can live with their legs like that because their body adjusts and strengthens the muscles in the right places to make up for it. She thinks that his body has done this, and will do this for his other leg when it goes out completely.
So, her answer was that surgery would be a waste of time and money. Now that's a first - a vet not wanting money!!! Just kidding.
She also said either way he is going to have arthritis, and even with surgery he is still going to have at least one bad leg.
So I dunno if I am happy or sad he doesn't need surgery. Of course the big thing is that it saves money, but then you kind of wish it could just all get fixed up for good and not have to worry about the future.
