Last month I met with an accident resulting in bilateral femure fracture. My fracture in right leg is more towards knee side, operation was done on 28th April and now its almost 6 weeks. But as I am doing various excercises to mobilize my muscles I see that in my right leg has become very stiff and seems to be swollen on that fracture area, but I can still do some movement but not very much like bending knee to 90 degree etc. Please suggest. Thank you.
