I had a total knee replacement on 5-14-08. I underwent 8 weeks of PT; my pain is still very bad and I have trouble sleeping at night and spend most of the night in my recliner chair. There is also a clicking (not audible) when I walk.....is this nnormal? My doctor insists that it is. He also said that it would take up to 1 year for full recovery. I feel I am worse off now than before the surgery. Is all of this normal recovery?
