we tend to advise our patients to avoid high impact activities following hip and knee arthroplasty procedures. so we do not want people running or jumping if it can be avoided. there really is no consensus opinion about activities following hip and knee replacement. different surgeons will allow different amounts of activity. if a patient of mine wants to do some weight training i tend to advise them to avoid really heavy weights and focus more on "reps". i also tend to tell my patients to try to maintain exercise as they can because i certainly feel that the benefit gained from the exercise likely outweighs the wear seen by the implant. it is certain that you will have less wear if you do not exercise at at all but that will likely come at the expense of your overall health.
what type of exercises are ok after knee and hip replacement?
