I have good news for you. According to a recent study conducted by Moffat et al there is good evidence that there is no down side to having your at home physical therapy provided via the internet and video. They showed no significant difference at four months after hospital discharge between face to face and video therapy after total knee replacements. They also described that the treatments provided were exactly the same. They included individual evaluation, supervised exercises, instruction in exercises to complete on days without a session, advice about pain control, use of walking aids and return to activities. The intensity and difficulty was based on each individual patients progress. This is good news for patients and therapists looking for the benefits of physical therapy following a total knee replacement, but do not have the resources to access at home face to face treatments.
