arthoscopy aftermath --- give my life back

I had a artroscopy for torn ACL on the left knee earler in april last year. I had gone through series of exercises as suggested by the doctor aftr the operation. I am comfortable sitting with my leg crossed.
I still am not able to bent my knee to fullest(10% bend is still not done, i cannot touch my hips with my bended leg). Because to this i still find problem in walking and my leg get stiff after some time. I have to be consicous enough that  dont hurt my leg again and get any more problem while doing daily routine job. i cannot hop or run until now.

please gve any solution to this problem. I want my life back
