I have had 5 major knee surgeries. 1st TKR Dec 2013, developed arthrofibrosis. Surgeries 2014 and 2015 to clean out scar tissue. Revision October 2018 for arthrofibrosis. Then major change. Had revision surgery 12/10/2019 by Henry Finn, Director of Orthopedic Surgery at Chicago Weiss Memorial Hospital and University of Chicago Hospital. Dr. Finn's process was to apply low dose radiation to the bone and scar tissue a couple of hours before surgery followed by a complete revision with a hinged implant. I am now 3+ months out from surgery and have been experiencing burning pain around the patella and radiating up a few inches an down the length of my leg. I had my other knee replaced in 2004 without issue but I am feeling a similar burning pain in that leg also, although not as intense. Does anyone have a suggestion as to what it might be?
