hey.
femur to heal fully in a healthy person... you're looking at in and around three months really.
studies have shown that if a fit and healthy person doesnt activate a muscle (say your quads) they will lose approximately 2% of muscle mass daily. you obviously have been activating to some extent but you will have a lot of weakness. pain also leads to inhibition of muscle activity which leads to weakness. you'l also have to strengthen the muscles round your hip too and your hamstrings.
you should be walking well enough in a couple of weeks provided you do the right exercises.
have you been referred to a physical therapist?
