I had a very rough time with TKR but the two things that really helped me were outside PT and frequent icing. I had my surgery two years ago and every now and then, I feel like I have *done something* to my knee and I have knee weakness and pain. When that happens, I take Advil, along with Extra Strength Tylenol and ice it. I think that the ice really helps! You should tell your surgeon that you would like to have an MRI on your knee just to make sure that you haven’t injured it. Also, if your insurance will cover it, maybe you should go back to PT for at least 8-10 sessions and get their take on it. I know how discouraging it can be to have gone through such a rough surgery and still have some pain. My OS did tell me that it takes a full two years for the knee to recover. Sending my best wishes to you for complete healing. MaryAnn in MA
