Misfeasance

I broke my leg playing soccer about 6 months ago. I got surgery about two weeks after and then I started physical therapy. So when I went to my physical therapist, Dr. Smith, he told me that I was fine and I didn't need to build up any more strength in my leg. He gave me a release form and I started playing again the next soccer season. I ended up injuring my leg again and the doctor said it was because my leg wasn't ready to preform on.
