Generally speaking, although many doctors say that patients can play various types of sports after surgery, in reality, because these artificial joints are inorganic materials, they are not living organisms, they do not have metabolism, there will be use, there will be wear and tear, and wear is wear and tear, it will not repair itself. Therefore, although there are many reports that patients can play various types of sports such as skiing, hockey, basketball, soccer, etc. after surgery, excessive strenuous exercise will accelerate the wear of the joints. Of course, this also depends on the individual’s pursuit of life, and there is no clear rule that one must not do the types of sports that ordinary people usually participate in on a daily basis. As for the problem of squatting on the toilet, because of the current large diameter femoral head, the stability of the joint is better and theoretically it is possible to squat. However, as a doctor, because there is still a local injury and risk of joint dislocation after surgery, we suggest that patients should not squat too much, especially in the early post-operative period and elderly patients. Of course, most of our patients who have had hip replacement surgery can squat, but I don’t recommend it because no one knows how much the patient can squat, and there is still a certain risk of dislocation if the patient exceeds the limit. Therefore, we recommend that hip replacement patients should not squat as much as possible, and should not perform cross-legged movements. However, for most patients, it is possible to put on socks and squat occasionally to pick up things, but it is important to note that these movements should be done only after a longer period of time, for example, 3 months or 6 months or even a year after surgery.
