Dr. Joseph F. Zabilski: A lot of people come into my office and ask me how long after hip or knee replacement will it be before I can return to my normal activities? And for the most part, the hip and knee replacements are very similar as far as timeframes. Usually, somewhere between four to six weeks, patients are walking pretty much independently. Sometimes between six or eight weeks, they can start returning to some of their activities that don’t involve higher impacts such as walking for exercise, possibly golf, swimming and things such as that. Once the muscles recover a little more fully and then fully rehab, then they can start returning to other activities such as easy doubles tennis and possibly even downhill skiing, staying away from those double black diamonds.
