My right leg bones dislocates every time

My right leg bones get dislocated every time I put stress on my right leg.i can't even run due to this as I am worried about the dislocation of knee joint. It happened in 2007 when some one suddenly jumped over my knee From outerside over my right leg pushing (towards the right leg from inside I sat down then and there it self and wasn't able to walk properly for next few months due to strain and swelling. Now some or the other time if by mistakenly my leg gets twisted my tibia and femur bones gets dislocated and I'm not able to walk as my leg get locked due to dislocation. After few hours it automatically gets into it's original place. I want a permanent solution over this where I can jump run and do physical activity
