July 2015 will be 1 yr. anniv. of Total Knee replacement. One month later I had a “manipulation”. My 90 degree flexion lasted just 2 days. I had 50 P.T. sessions (including water therapy,which only reduced my flexion) I finally found a P.T. that got to know my knee !! He spent hours working on reducing scar tissue ! My flexion is 90 degrees on a good day. My P.T. has given me 2 exercises to do at the gym. Leg press & walking on treadmill for 10 min. I am still unable to walk up or down stairs.I experience back pain after grocery shopping & other small household chores. By 3:00 p.m. my knee begins to swell ( no matter what I have done) My P.T. said that I easily develop scar tissue & swelling of my joints. It has been recommended that I have this knee replaced.After reading other patient experiences I am very unsure. I have been told by numerous people that Minn.Mayo Clinic is #1 for successful replacements.
