 Hello, I'm Dr. Sunil Kini, consultant joint replacement and arthroscopy surgeon at Manipar Hospital's Bangalore. Immediately after knee replacement, we advise the patient to start walking the very next day after surgery. The extent of the patient walking is determined by the level of pain as well as the swelling. By the time of discharge, patients are usually comfortable walking in the corridor. They also can do a couple of steps by the time they are discharged. This improvement slowly occurs over a period of time to up to six weeks or even three months after surgery. The do's after a knee replacement is almost everything. So, the patient can be back on their feet, can do all activities including light work and after six weeks they can resume their most of the activities of daily living. In terms of people who drive, at six weeks would be the safe limit at which the patient can start driving as well. For patients who do stairs immediately after surgery by about two to four weeks, patients are comfortable doing a flight of stairs and this improves. By about four to six weeks after surgery, the patient can walk at least about half a mile and this improvement slowly is seen with progressive distance walking. In terms of patients who want to ride a stationary bike, six weeks to three months would be the time when patients can start to do so. A patient who want to play sport such as golf or doubles tennis, it will say probably three months to six months is the duration at which we start looking at. Swimming is also very good activity and we encourage patients who can do so to start at about six weeks to three months after surgery. The do's after surgery, the couple of things which advice patients not to do firstly is to a lot of impact activities such as a running or jogging which actually puts more strain on the plastic and the implant and subsequently there may be more chances of loosening and polyethylene wear. Also in the Indian patients we advise them not to use an Indian toilet because it requires a lot of forces on the plastic during deep squatting. Also a common question is whether patients ask whether they can sit crosslet on the floor. Although they could, we advise the patient that there are slightly more chances that the plastic wears off during this process and it's best to avoid if possible or only in certain occasions wherever needed.
