I am 3 1/2 years post Left TKA; 2 1/2 years post right TKA. Both are still giving me problems. I had a terrible rehab with my first one. Pain, tight band, took a long time to flex to 100 degrees...with 2 PT's pushing, me pulling and me crying. Used a can for 4 months. The right one rehabbed much better, but I have a burning pain in both...from a couple inches below the knees to an inch or so above the knees. I fear it's neuropathy. I can walk distances much better than stand still or minimal walking, like working in my kitchen. It became worse last fall, so well over 1 and 2 years post op. Some days I feel like I'll be in a wheelchair before long; other days slightly better but I've never been without discomfort. I got a 2nd opinion while in Arizona this past winter; both he and my PA here at home say I likely drew the short straw of the 20% whose knees don't like them. Both said if the burning continues to consider seeing a neurologist, which I plan to do soon. I also have pain in the side of the knee if I sit certain positions. Driving with foot on the gas pedal is very uncomfortable when I can't use cruise control. I really didn't have the option of not doing the surgeries....arthritis doesn't get better and I was bone-on-bone and resorting to a cane.
