Thanks for sharing another story of Orthopedists playing roulette. I'm an unsuccessful TKR recipient and into 7 1/2 years post surgery, including a revision. I probably heard every diagnosis why I have pain from soup to nuts. The latest this month is one doctor recommended I have a nerve block, followed up with another new ortho wanting to give me a cortisone shot in my hip explaining that sometimes the pain is transmitted to the knee. Yes sirree, they're throwing anything on the wall to see what sticks. Of course they don't advise you of the detrimental cortisone effects and none want to do an MRI. No wonder they have you sign all those waivers before surgery.
