Hip Replacement Patient Guide To Surgery
Total hip replacement surgery is also called total hip arthroplasty. This means that your hip joint is surgically replaced. During the operation, the damaged part of the hip (ball and socket) is removed. It is replaced with artificial parts, called components or prostheses (pros - THEE - seez). The type of fixation is determined by your bone quality, activity level, and weight. Most people can leave the hospital after a one night hospital stay and some can go home the same day. The procedure takes approximately 60 to 90 minutes to perform. It is done through an incision which is as small as possible to allow adequate visualization for your surgery. A walker or crutches are used for approximately 2 to 4 weeks, then a cane for 1 to 3 weeks. Ninety to 95 percent of patients are happy with the results after surgery. Your surgeon chooses the parts that are best for you.
Figure 1 shows you what the artificial parts look like and where they are located in the hip.
Surgical approach
There are three basic approaches used in total hip replacement. These are direct anterior, lateral and posterior. They all have their advantages and disadvantages. Different approaches are used for different surgical problems.
Implants
Most hip replacements are performed with implants designed to grow into you bone. At our Joint Center we use primarily DePuy, state of the art implants. None of the implants we use have been recalled and all have industry leading track record for survivorship and durability.
Bearing surfaces and head sizes
There are three main bearing surfaces with their own advantages and disadvantages
Highly Crosslinked Polyethylene
Metal (Cobalt Chromium)
Ceramic
Most primary hip replacements utilize ceramic or metal femoral heads and highly cross linked polyethylene inserts, consistent with industry standard. Our surgeons occasionally utilize ceramic on ceramic bearings in unique situations.
How long do they last?
Obviously, results can vary, based on many factors. In general, 90-95% of patients are happy with the outcome of their joint replacement surgery, and they return to most activities. We recommend avoiding such as running, jumping, and lifting excessive weights. Depending you your age and activity, 90% of patients can have their total hip last at least 15 years, maybe longer.
