As a matter of fact, elderly people do not have their hips replaced, but their hip joints, that is, hip replacement surgery. The time it takes to return to normal after hip replacement surgery for the elderly is usually 3-4 months, but the exact recovery time will depend on post-operative wound healing, post-operative nutritional supply, and the patient’s health. Elderly hip replacement is a relatively large operation. After the surgery, if the wound heals well and calcium and nutrition are supplemented in time, coupled with the fact that the elderly are healthy and have fewer underlying diseases, the recovery time will be relatively short. Clinically elderly patients who have wound infections, misaligned joints, are unable to keep up with nutrition, or have many underlying diseases will have a correspondingly longer recovery time. Elderly people should pay attention to rest and timely nutrition after hip replacement to avoid various complications. At the same time, family members can give leg muscle massage to prevent muscle atrophy.
