I had a partial knee replacement on Oct 25th, everything seemed to be going well. Physical therapy was going good, was taking longer and longer walks, then on Dec 5th, the pain started. With every step I take now I can feel where the bone meets the replacement. The pain is unbearable at times. This was my 9th knee surgery. Has anyone experienced this type of problem and if so any solutions? I am still going to physical therapy, but not taking my walks. A total knee replacement was not an option due to the damage and age of 43.
