Hi all, I just found this board today as I was searching for some information on the CPM machine. CONTINUOUS PASSIVE MOTION. I'm not new to this machine for my knee. My nightmare began on 9/11/2006. I had to have a TRK replacement that day. I'm in my 40's, and when I was 22 I was in a car accident, and hurt my knee pretty bad. However, I lived a normal life without pain until the Beginning of 2006. In August, I finally went to the "same" surgeon that operated on my knee 20 something years ago, and he told me I was "bone on bone" and said I had to have a total Knee Replacement. On the day of surgery,..everything went well. I started PT right and it was Brutal. The pain was so intense, and after 2 months, I reached 95 degrees with little pain. My surgeon wasnt satisfied with that number and said I "needed" a manipulation. (Surgeon takes his own hands while I'm asleep under general anthesia), and tries to break up scar tissue.) During my 30 minute ouptatient surgery, my surgeon went way to far, and broke my femur bone completely in half at the largest part. He had to go out and tell my family memeber(s) that was there that"...I fractured her femur bone". I had to have another major surgery to put a plate and screws in my leg due to the break. He broke it on November 13, 2006. almost 3 months after my knee replacement. Since I had to let the largest bone in our bodies heal, (which took a year)...my range of motion kept going down. It dropped down to 20 degrees and locking up. The pain was so intense that my Primary Care Physician had to manage my pain, and I had to take lots of narcotics for a solid year. Well 2 weeks ago,.....another surgeon with another group did a total knee revision, to fix and clean up the mess that the first surgeon made. The only way this surgeon would touch me was because he happened to be my sisters best friends husband. No other surgeon would, not in my large city anyway, when the news spread about the doctor breaking my femur bone and admitting that he went to far. So right now, I'm starting PT all over again, and its brutal. I'm only at 70 degrees at my best, and going through all the swelling,..etc that all of you are experiencing. My point to this post,...is PLEASE,..PLEASE NEVER LET A SURGEON DO A MANIPULATION ON YOUR KNEE AFTER A TKR, WITHOUT ASKING QUESTIONS AND GETTING A SECOND OPINION. MY NEW SURGEON SAID THAT MY BAD SURGEON SHOULD HAVE DONE AN "INTERNAL" MANIPULATION INSTEAD OF AN "EXTERNAL MANIPULATION. That means my leg didnt have to break. He could have done what my new surgeon did, and cleaned out all the scar tissue from the inside out, by going back through the same scar. Our femur bone becomes weaker when we have a replacement added. I will be lucky if I get to 90-95 degrees for the rest of my life. I'm in very intense therapy 4 days a week, and its so brutal as most of you know. I'm also on massive amounts of narcotics(again) due to the extreme pain during therapy and out. Im sorry this was so long. I wanted to share this so maybe I could help someone to not become a victim of a broken femur bone, that my first surgeon did as he tried to play God. His exact words were" I had your knee to 120 and I was going to 125" "We heard the break, I put your leg down, we x-rayed it and I realized I fractured your femur bone" Please ask me any questions, as I would love to help anyone needed answers. I can also learn alot myself. Thanks, skye
