I there. I had a lateral release and Tibial Tuberosity Osteotomy operation done 7 weeks ago. The first month for me was the worst; I couldn't walk or bend my leg. But PT has been so essential. Each week I go back and realise how far I've come. I'm now bending 105' and am walking normally, driving etc. stair climbing is still hard. So please don't feel too dejected - it will get better quicker than you think. If you'd like to know anything else, feel free to e-mail me. I can only tell you how I felt, but would be happy to offer my own advice.
