General rules of total hip replacement that the patient needs to follow are:
In the first six to eight weeks after the operation, the individual receiving a total hip needs to avoid bending the hip beyond 90 degrees. This can be achieved by keeping knees below the hips when sitting. Sitting on a small pillow can help with this positioning. Avoiding sitting in sofas or couches which may cause excessive bend at the hip.
Avoid bending over from the hip to reach the floor.
Avoid crossing the surgical leg over the non-surgical leg. When sitting, it is good advice to keep the legs three to six inches apart.
Avoid turning the operated leg inward, i.e. pigeon-toed.
