Hip replacement is the removal and replacement of portions of the pelvis and femur (thighbone) that form your hip joint.

 

Hip replacement is a surgical procedure in which the hip joint is replaced by an artificial prosthetic implant. The procedure is called hip arthroplasty. The surgery is generally conducted to relieve joint pain (arthritis) or for the treatment of physical hip joint damage and hip fractures. Hip replacement surgery can be performed as a total replacement or a hemi (half) replacement.

In a total hip replacement (also called total hip arthroplasty), the damaged bone and cartilage is removed and replaced with prosthetic components.

• The damaged femoral head is removed and replaced with a metal stem that is placed into the hollow center of the femur. The femoral stem may be either cemented or "press fit" into the bone.

• A metal or ceramic ball is placed on the upper part of the stem. This ball replaces the damaged femoral head that was removed.

• The damaged cartilage surface of the socket (acetabulum) is removed and replaced with a metal socket. Screws or cement are sometimes used to hold the socket in place.

• A plastic, ceramic, or metal spacer is inserted between the new ball and the socket to allow for a smooth gliding surface. 

What are normal amounts of pain after hip replacement surgery?

Your surgeon will remove damaged pieces of your hip joint and replace them with artificial parts composed of metal, ceramic, or plastic during a hip replacement. In the long run, these components should increase your range of motion and alleviate whatever pain you are currently experiencing. A hip replacement, like any surgical operation, can cause temporary pain.

Because each individual and case is different, it is difficult to predict how much agony you may feel after surgery. Always consult your doctor about the type and level of pain you're experiencing during your recuperation, and follow their pain management recommendations.

Typically, many patients may find relief from over-the-counter medications, such as Tylenol (acetaminophen). The Food and Drug Administration (FDA) considers 2,000-3,000 milligrams per day to be safe, but you should consult with your doctor regarding an appropriate regimen for your specific needs. For example, if you are elderly or have a history of liver problems, you will need a smaller dose.
