Limping while walking. On the same!

Hi, I met with an accident in January 2014, in which I had my femur bone crushed due to the impact of the accident, I went an surgery in which Titanium was implanted in my Thigh and also in the Knee. There has been constant limping since then while walking and apart from that, the most annoying problem is that I am unable to fold my knees completley, hence Even in worst of the Situations in which If have to go to washroom in Indian Toilets, I cannot go to washroom, I cannot attend any sports activities and cannot even try on swimming, The doctor when operated he told that Titanium can be removed after 1-2 years, I got an Xray done in which the Bone has regenerated , but I have a fear before going for the operation is that whether the operation be worth it and will it help me gain back the normal movement and apart from that will I be able to gain back the complete movement of my knee back, Kindly Advise on the same
