For most patients who need hip replacement, a new, artificial hip joint leads to reduced pain and better function. Studies show that the surgery helps to relieve pain in more than 90% of patients.
However, any type of surgery poses risks, such as infection and blood clots in the legs or lungs. Some possible complications from hip replacement surgery include abnormal bone growth or calcium deposits, loosening or breakage of the implant, and fracture of the bone. In about 1% of patients, hip replacement surgery leads to nerve damage, usually in the sciatic nerve.
Overall, the benefits of hip replacement surgery often outweigh the risks, and the risk of serious complications is generally low. However, it is important to talk to your doctor about the risks and benefits in your individual case.
