I have the ostyophytes in my neck,which I hear crackling when I move it. I had one on my left shoulder in which put a small tear in my rotary cuff. I do not like PT as I think its all about the money and not your success. The more you move it,the more it grinds into you. I believe this anyways with many years of this experience. They are bone spurs,no PT will rid them. The doctor filed mine down on my shoulder to make it smooth. I am not familiar on the femur and if this is possible,but I believe so now a days what they can do. Go with your gut,and do lots of research on your own. Doctors are great,but not always for your benefit.My opinion anyways! Hope this helps a little
