Man I had to have the microfracture surgery later and that was causing a lot of pain and weakness until I had that surgery. Since that I just go nuts right away. It feels good. I strengthen it like crazy. I spend a lot of time doing balance things and strengthening my hips so that it does not happen again. To get used to taking the hits I would run to the park and jump off of a picnic table and practice landing on the ground with good form. I have a friend who blew up his knee about a year before me and when I was sitting at home being depressed he said the best advice I have ever received "Only sissies make it through life without blowing up a knee." Hehe. Just keep plugging away you will get comfortable again. I think you need to really build up your balance, i.e single leg activity, and strength.
