Hip Replacement

Hip replacement surgery, also called total hip arthroplasty, involves removing a diseased hip joint and replacing it with an artificial joint, called prosthesis.

The normal hip joint is a ball and socket joint. The socket is a "cup-shaped" bone of the pelvis called the acetabulum. The ball is the head of the thigh bone (femur).

Total hip joint replacement involves surgical removal of the diseased ball and socket and replacing them with a metal ball and stem inserted into the femur bone and an artificial plastic cup socket. The metallic artificial ball and stem are referred to as the "prosthesis." Upon inserting the prosthesis into the central core of the femur, it is fixed with a bony cement called methylmethacrylate. In some cases, a "cementless" prosthesis is used which has microscopic pores that allow bony ingrowth from the normal femur into the prosthesis stem. This "cementless" hip is believed to have a longer duration and is considered ideal for younger patients.

There are number of hip replacement techniques:

Traditional Hip Replacement: The typical hip replacement procedure uses either of two approaches performed through similar incisions located on the upper thigh and buttock. One is called a posterior-lateral approach and the other is the anterior-lateral approach.
Minimally Invasive Techniques: This technique may use smaller incisions combined with traditional approaches, as well as, alternate surgical approaches employing smaller incisions or sometimes two incisions
Total hip replacements are performed most commonly on patients suffering from progressively severe arthritis in the hip joint. The most common type of arthritis leading to total hip replacement is degenerative arthritis (osteoarthritis) of the hip joint. This type of arthritis is generally seen with aging, congenital abnormality of the hip joint, or prior trauma to the hip joint.

After the surgery, you will be sent to the recovery room where your heart rate blood pressure and respiration will be monitored. You will be given pain medication, by various means depending on your surgeon's plan.

The goal of your inpatient hospital stay is to prepare you for discharge from the hospital.
