Hip replacement surgery is usually done successfully without too many problems and the mortality rate for hip replacement surgery is between 0.8 percent to 0.25 percent.
The reason people die due to hip replacement surgery is usually because of blood clots forming which can break off and then travel to your lung, heart and sometimes but rarely your brain.
Total hip replacement surgery is considered to be major surgery so you should only get hip replacement surgery if you really think you need the hip replacement surgery.
Sometimes it's better to not have the hip replacement surgery done.
