After artificial hip replacement, some patients do not pay attention to the protection of the new joint, thinking that the joint is replaced and they can rest easy; some patients are overly concerned about the new joint and are careful about everything. So, after artificial hip surgery, what kind of exercise and diet is “moderate”, let’s talk about it. 1, within six weeks after surgery is not recommended to do squatting and wearing shoes, socks and other movements; six weeks after surgery, wearing shoes, socks, walking and jogging, swimming and other acts can be carried out. If some patients are unsure and think that six weeks after surgery is too early, they can also postpone it to three months later; 2. After artificial hip replacement, it is not completely impossible to “stilt” or cross your legs. It is just that these behaviors should be done only after the patient has recovered well for three months after surgery. If you do “stilts” or cross-legged actions within six weeks after surgery, it is likely to lead to hip dislocation, which is very dangerous; 3. Patients should not sit for a long time after surgery, because sitting for a long time is a test for the hip joint and lumbar spine. Generally speaking, this “long time” refers to more than 30~40 minutes. In other words, it is recommended that patients sit for 30-40 minutes and then stand and walk for a period of time; 4. When going up and down stairs after surgery, patients should pay attention to “good up and bad down”, that is, the leg on the healthy side goes up first when going upstairs and the leg on the operated side goes down first when going downstairs. In addition, within three months after surgery, patients should try to hold the handrail when going up and down the stairs. On one hand, the joint may not be very stable after hip replacement; on the other hand, patients may fall after surgery due to muscle weakness. However, three months after the surgery, if the patient has recovered well through the side leg lift exercise, there is no need to be so careful; 5. If the femoral head necrosis is caused by alcohol consumption, and then the hip joint replacement is needed, it is still recommended to quit drinking or reduce alcohol consumption even after the new joint is replaced. This is because continued drinking after surgery may lead to necrosis of the femoral head on the opposite side (the good side) and may also cause damage to the liver and kidneys; 6, there are not many cautions in terms of diet after artificial hip replacement, and there is no need to avoid eating because of surgery.
