Can an Orthopaedic Surgeon be held responsible for an operation going bad, such as a Total Knee Replacement operation.

Calhoun Orthopaedic Surgeon, Doctor did a total knee replacement on me in September 2013. In January 2014 of this year, only three(3) months after the surgery was done, my entire knee cap came undone and now my knee cap is sitting on the side of my leg instead of in front of my knee where it is suppose to be. When I went to Doctor's office and asked him what was wrong with me, he sent me home with a brace on my leg and told me to keep my leg up and come back to see him the next month. I felt that I needed to talk to another doctor, so I went to see two other doctors and they each informed me that I needed surgery done but both doctors informed me that they would not do surgery behind another doctor, and that the doctor that did the first operation should do this one because he was the one who made the mistakes that caused my knee to come apart. When I explained to the doctor who did the surgery that he had to do another surgery on my knee, he refused until he gets paid again.
