@heyjoe: My reason for doing this twist on the standard heel slide was to get the muscles and ligaments used to the increased bend. When using the other leg, or some type of band to force the TKR knee to bend more, my muscles (or mind?) always resisted that. But with the self-imposed, gentle (!!) enforced bend it felt more natural, and after a week or 2 the TKR knee seemed looser, more relaxed, and capable of increased flex. May not work for everyone, but for me - ok. And one more general advice: if possible, post TKR patients would benefit tremendously from having access to a pool. A trained attendant can develop specific exercises for TKR rehab (did for me), and those are sooooooo much less painful to do under water than they are “on land”.
