My husband developed arthrofibrosis after TKR. He went in to remove some scar tissue to improve his range of motion and developed a deep tissue infection from the hospital. This led to a debrinement procedure to remove the infected tissue along with several pounds of scar tissue. After six weeks of IV antibiotics and six months of oral antibiotics the infection was still present. Then they removed the hardware, infected tisssue and put in a temporary knee. We then discovered that his original knee was too large and not placed properly causing his leg to face outwards. The surgeon reshaped his tibia and femur and corrected his gate. After six weeks of IV antibiotics the infection was gone. Three weeks ago they removed his temporary knee and put in the permanent revised knee. Under anesthesia they were able to get his knee to 110 degrees. They did adjust his patella and removed scar tissue from his quadricep. We had met with several surgeons before the first tweaking procedure and had decided it was worth the risk to remove a small amount of scar tissue to improved range of motion. On the bright side he would not have been able to under the care of the revision specialist to correct the implant if he hadn’t developed the infection. He is currently using the continuous passive motion machine and will be graduating from home pt to in person pt next week. We are worried that if we do not push the movement in these first few weeks he will develop more scar tissue and never regain his range of motion. We are looking advice on how to use the continuous passive motion machine and pt to help him regain maximum range of motion without aggravating his arthrofibrosis.
