I had some knee and leg pain but I do not think it was a bad as yours. It is starting to diminish now. My theory is that our hip muscles are not helping much at all as we go through our rehab. This places a lot more strain on the existing leg muscles to make up the difference, hence the pain and soreness. I did a tremendous amount of leg exercises going in and was surprised with the muscle soreness after surgery. As those muscles that were messed with during the surgery recover, our pain starts to diminish. Well, that is my theory - right or wrong.
