Hi ddsack,
I had a second opinion appointment because my recovery from TKR has been so difficult. He surmised from his fairly brief analysis that I had a damaged pcl ligament and weak quad muscles. He wanted me to spend the next four months focusing on strengthening my quad muscles. Which I do primarily in the gym but saturday night in my house just normally taking a step my right knee collapsed on me. I have scheduled an x-ray but when I see my surgeon doctor should I insist on another machine because the x-ray always comes back fine?
