Hip replacement is a common and very successful surgery for people who have chronic pain and/or movement problems in one or both of their hip joints.
Hip replacement is the removal and replacement of portions of the pelvis and femur (thighbone) that form your hip joint. It is performed primarily to relieve hip pain and stiffness caused by hip arthritis.
This procedure is also sometimes used to treat injuries such as a broken or improperly growing hip, and for other conditions.
If you have these arthritis symptoms, you should consider a hip replacement:
The hip is a ball-and-socket joint. The ball, at the top of your femur (thighbone) is called the femoral head. The socket, called the acetabulum, is a part of your pelvis. The ball moves in the socket, allowing your leg to rotate and move forward, backward and sideways.
In a healthy hip, soft tissue called cartilage covers the ball and the socket to help them glide together smoothly. If this cartilage wears down or gets damaged, the bones scrape together and become rough. This condition, known as osteoarthritis, causes pain and restricts motion. An arthritic hip can make it painful for you to walk or even to get in or out of a chair. If you have been diagnosed with hip arthritis, you may not need surgery. Nonsteroidal anti-inflammatory drugs (NSAIDs) and/or physical therapy may provide relief. But, if these efforts do not relieve symptoms, you should consult an orthopedic surgeon.
The three major types of hip replacement are:
The most common type of hip replacement surgery is called a total hip replacement (also called total hip arthroplasty). In this surgery, worn-out or damaged sections of your hip are replaced with artificial implants. The socket is replaced with a durable plastic cup, which may or may not also include a titanium metal shell. Your femoral head will be removed and replaced with a ball made from ceramic or a metal alloy. The new ball is attached to a metal stem that is inserted into the top of your femur.

Two other types of hip replacement surgeries are each generally appropriate for patients of specific age groups and activity levels:
There are two major surgical approach methods for peforming a total hip replacement:
The two most common surgical approaches in hip replacement are the posterior approach and anterior approach (sometimes called the "mini-anterior approach" or "muscle-sparing hip replacement").
To begin the operation, the hip replacement surgeon will make incisions on either the back (posterior) or front (anterior) of the hip. Both approaches offer pain relief and improvement in walking and movement within weeks of surgery.
There are certain steps patients can take both before and after surgery to improve recovery time and results. It is important to follow the instructions and guidance provided by your orthopedic surgeon, medical team and rehabilitation therapist.

Most patients will stay in the hospital one or two nights after surgery. Some patients may be able have same-day hip replacement and return home after an outpatient procedure
Same-day, rapid recovery or outpatient hip replacement surgery means that a patient goes home to recover on the day of their procedure. This is possible due to advancements in technology, technique and pain management, and it offers many benefits to those who qualify for this procedure. Patients who are in good general health, do not smoke, are motivated and have a good support team at home are the best candidates. Those who qualify are given special education on their recovery, which must be followed closely. The benefits of this surgery include:
HSS joint replacement specialists perform a thorough evaluation of each patient’s individual circumstance in order to determine their eligibility for same-day hip replacement surgery.
Total hip replacement surgery takes about one and a half hours. Most patients also stay in the hospital for one or two days after the procedure.
Your rehabilitation within 24 hours after surgery. Most hip replacement patients progress to walking with a cane, walker or crutches within day or two after surgery. As the days progress, you will increase the distance and frequency of walking.
If you have THR surgery at HSS:
The surgery is very safe, but every surgery has risks, and infection is the most serious. You should ask your surgeon what the surgical infection rate is for hip replacements at the hospital or facility where you will have your surgery.
HSS is a leader in preventing infection. A New York State Department of Health report stated that out of more than 160 hospitals in New York that did hip replacements in 2014, only Hospital for Special Surgery had a hip replacement surgery site infection (SSI) rate that was "significantly lower than the state average" for that year, and that those infection rates at HSS had been significantly lower than the state average in each of the seven years between 2008-2014.
Other risks include blood clots in the leg or pelvis, and accidental hip dislocation during or after recovery. Hospital for Special Surgery performs better than the national average in preventing blood clots after surgery.
Generally speaking, a hip replacement prosthesis should remain effective for between 10 and 20 years, and some can last even longer.
Results vary according to the type of implant and the age of the patient. In a 2008 study of more than 50,000 patients who had THR surgery at age 55 or older, between 71% and 94% still had well-working implants after 15 years.*
When a hip implant does need to be replaced because it has loosened or worn out over time, this requires what is called hip revision surgery.
Yes, healthy patients younger than 75 years old who have no history of cardiopulmonary disease may be able to have both hips replaced at once. In some cases, however, it may be better to stage the surgeries.
There are three separate implants: the stem, the ball and the socket.

Today's sensitive screening machines will detect the implant but can also effectively identify it. The machine operator will know that it is an implant rather than an unauthorized metal object contained outside the body.
It is still helpful to tell airport security that you have had a hip replacement before entering the screening machine. You may also ask your doctor's office if they can provide a card that identifies that you have received a hip implant that contains metal.
Most patients can resume driving by six weeks after surgery.
When looking for an orthopedic surgeon to perform your hip replacement surgeon, it’s important to do your research and check the surgeon’s credentials, experience and reputation. It is also important to research the hospital or facility where you will have your operation, as well as its supporting staff, such as the anesthesiologists.
HSS has one of the lowest rates of infection for hip replacement surgery, as well as a significantly lower rate of readmission compared to the national average. HSS also performs more hip and knee replacements than any other US hospital and is ranked the No. 1 hospital for orthopedics in the United States by U.S. News and World Report. No other hospital in the world focuses solely on health problems of the bones, joints and soft tissues like muscles.
The success rate for hip replacement surgery at HSS is very high. In a study, HSS interviewed patients to learn about their progress. Two years after their surgeries, 99.4% of patients said they had relief from pain, 98.8% said their ability to move was improved, and 97.8% said their quality of life was better because of their surgery.
