Your hip is hurting so bad, you can't sleep. It's hard to bathe, to clean, make it to the mailbox or shop at the mall. You may have severe arthritis in your hip, and there's a good chance you need a hip replacement.
Hip replacements are usually done in people age 60 and older. If you need one, you probably have severe arthritis that limits your daily life, or perhaps have a hip fracture.
Your hip joint is made up of two parts, the hip socket and the upper end of the thigh bone. One or both parts may be replaced during surgery. Your new hip will probably have a socket made of strong metal, a liner that fits inside the socket, usually plastic, a metal or ceramic ball to replace the round head of your thigh bone, and a metal stem attached to the thigh bone to make your joint more stable.
So, how is the hip replacement procedure done?
Well you won't not feel any pain during surgery because you will have medicine to make you fall asleep. The surgeon will cut and remove the head of your thigh bone and clean out your hip socket, removing cartilage and damaged or arthritic bone. The surgeon will put the new hip socket in place, insert the metal stem into your thigh bone, and place the ball for a new joint. Cement will probably hold the new joint in place. The surgery can take several hours.
After the surgery, you will probably stay in the hospital for three to five days. As soon as the first day after surgery, you will be asked to start moving and walking around with a walker, crutches, or a cane. You will need physical therapy to strengthen your new joint for up to several weeks after your operation. Some people need a short stay in a rehabilitation center after they leave the hospital. At the rehab center, you will learn how to safely do your daily activities on your own.
Your new hip should allow you to resume your daily activities once you've learned to move around on your own. In the long run, over 20 years or so, the joint may need to be placed again. But, in the short run, most or all of your pain should go away. The stiffness should go away. Your doctor should be able to monitor any problems and you should enjoy your new joint.
