I have a question regarding sideways/twisting motion after TKR. 11 weeks after the surgery I am making very good progress regarding ROM, and forward/backward movement (as in squats, lunges, going up and down stairs). HOWEVER, things are nor really progressing with sideways motion, as when you are standing and bending your knee out and your foot up - as you would when pulling off a sock, for example, or doing heel touches. I have been working on that some in the pool, but it is still pretty painful. Is this common, how long will it last, will it ever get better?
