I have had a left knee replacement in 2014 and today only can get a 95 degree. I dance and walk fine. I found out from a muscle specialist that my knees were not working. I also have arthrrtitis in right knee. I ride a stationary bike in hopes to get more bend out of my left knee. My right knee is only 105 but working to get more back into the range of motion. I know it is scar tissue in left knee. Any ideas of how to break up this tissue over a period of time.
