I had TKR 26 months ago on one knee following my orthopedist diagnosing me as having near bone on bone on both knees. My present status on the TKR is one of having all the negative outcomes possible, i.e., pain, can’t squat, can’t kneel, knocking, limited range of motion and stiffness. Needless to say my quality of life has suffered. My good working knee, the one that wasn’t replaced, is beginning to bother me when I overwork it. I don’t want to make another mistake with a decision to replace it because it brings on a fear I may be totally incapacitated.
