@contentandwell : JK, I am not even certain that my legs were the same length before the TKR. They never gave me any problems before. Perhaps the almost 2 years of compensating for one sort of pain or another (knee, back, hip) has simply caused my muscles and tendons get out of whack, rather than that the surgery lengthened the leg. The result is the same, though - trouble walking normally. PT (5 days doing the exercises at home) does seem to help as far as relieving the tightness and pain in the left leg; unfortunately those exercises are tough on the TkR knee and the hip on that side, where I just got over the bursitis bout. There’s always something, I guess. Oh, to go back to the good young days of being 68, before this whole mess started!
