After hip replacement surgery, if you have recovered well, you can wear pants by yourself about one month after the surgery. However, there are still some points to note when wearing pants, first of all, wear the side of the replacement joint, avoid the side of the replacement joint to bend the hip more than 90 degrees. In addition, avoid internal rotation and internal retraction, otherwise the hip joint may be dislocated. After hip replacement surgery, besides wearing pants, you also need to pay attention when wearing socks and try to avoid hip flexion over 90 degrees. After hip replacement surgery, the prosthesis has a certain life span, generally about 15 years on average. Pay attention to your personal habits and try to avoid long distance walking and strenuous exercise to help reduce the wear and tear of the prosthesis and prolong its service life.
