What are the other Names for the Procedure?
- Hip Replacement Surgery
- Total Hip Arthroplasty
What is the Total Hip Replacement surgical procedure?
- A Total Hip Replacement procedure is a surgical intervention technique that involves the complete removal and replacement of the hip joint
- It is recommended for individuals who have a degenerative joint disorder, such as osteoarthritis, or an injury that affects the entire hip joint
What part of the Body does the Procedure involve?
A Total Hip Replacement procedure involves the hip joint, muscles, surrounding ligaments, bones and bursa, which shape the hip.
- The hip is a ball-and-socket joint
- The socket is formed by the acetabulum, which is a part of the pelvis bone. The ball is the femoral head, which is the upper end of the femur (thigh bone)
- The bony surfaces of the ball and socket are covered with a smooth tissue, called articular cartilage that cushions the ends of the bones and enables them to move easily
- The hip joint is surrounded by a thin tissue, called the synovial membrane, which produces a small amount of fluid that lubricates the cartilage and eliminates friction during hip movement
- Ligaments (the hip capsule) are the bands or tissue that connects the ball to the socket and provide stability to the joint
Why is the Total Hip Replacement surgical procedure Performed?
A Total Hip Replacement surgery is performed for the following reasons:
- When there is a degeneration of the hip joint
- Due to an injury to the hip, which causes pain and reduced mobility, impairing an individual’s quality of life
What are some Alternative Choices for the Procedure?
- Conservative therapy, such as pain medications, physical therapy, exercise, and use of a cane or walker, may be recommended initially
- For patients with significant damage to hip joint, Total Hip Replacement procedure remains a gold standard approach
What are the Recent Advances in the Procedure?
Use of less invasive techniques has been the recent advances in the procedure.
What is the Cost of performing the Total Hip Replacement surgical procedure?
The cost of Total Hip Replacement procedure depends on a variety of factors, such as the type of your health insurance, annual deductibles, co-pay requirements, out-of-network and in-network of your healthcare providers and healthcare facilities.
In many cases, an estimate may be provided before the procedure. The final amount depends upon the findings during the surgery/procedure and post-operative care that is necessary.
When do you need a Second Opinion, prior to the Procedure?
- It is normal for a patient to feel uncomfortable and confused with a sudden inflow of information regarding Total Hip Replacement procedure and what needs to be done
- If the patient needs further reassurance or a second opinion, a physician will almost always assist in recommending another physician
- Also, if the procedure involves multiple surgeries or has many alternatives, the patient may take a second opinion to understand and choose the best one. They can also choose to approach another physician independently

Prior to Total Hip Replacement surgical procedure:
How is the Total Hip Replacement surgical procedure Performed?
The Total Hip Replacement surgery is performed as follows:
- The damaged hip joint is removed and replaced with prosthetic components
- The head of the thigh bone is removed and replaced with a metal stem that is placed into the hollow center of the femur
- The stem may be secured in place, either with bone cement, or is "press fit" into the bone
- A prosthetic (metal or ceramic) ball is placed on the upper part of the stem. This ball replaces the femoral head that was removed
- The damaged acetabulum is removed and replaced with a metal socket
- Screws or cement are 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
There are two basic types of hip replacement procedure: Standard hip replacement, and minimally invasive approach.
Standard Total Hip Replacement surgery:
- This involves a bigger incision in the affected hip
- Some of the muscles are detached to expose the joint
- The damaged bone and cartilage are removed and the artificial joint (prosthesis) inserted
- The new socket attaches to the pelvic bone and the ball, to the top of the thigh bone
Minimally invasive surgery:
- Hip replacement can now be performed using less invasive techniques, using smaller incisions
- These techniques can be performed with regional anesthesia. Minimally invasive techniques comprise:
- Anterior approach: Performed through an incision in the front of the hip
- Posterior approach: Performed through an incision in the back of the hip
- Anterolateral approach: Performed through an incision on the side of the hip
Where is the Procedure Performed?
The Total Hip Replacement surgical procedure is performed in a hospital.
Who Performs the Procedure?
An orthopedic surgeon performs a Total Hip Replacement procedure.
How long will the Procedure take?
A Total Hip Replacement surgical procedure may take anywhere between 3 to 5 hours.
What do you need to tell your Physician before the Procedure?
It is very important to provide the following information to your healthcare provider. This enables your healthcare provider in assessing the risks for the surgical procedure and helps avoid unnecessary complications.
- Provide a complete list of medications you are currently, taking to your physician. This information is useful for a variety of reasons. For example, it can help your healthcare provider prevent complications due to a drug interaction
- If you are allergic to any specific medication or food items
- If you are taking blood thinners, such as aspirin, warfarin, herbal supplements, or any other such medications
- If you or your family members, have a history of bleeding disorders, or if there is a tendency to bleed more than normal
- If you have diabetes, high blood pressure, chest pains, or have previously suffered from a heart attack
- If you have ever been diagnosed with blood clots in your leg (deep vein thrombosis) or lung (embolism of lung)
- If you have a history of frequent bone fractures (this may affect bone-healing, if bones are involved as part of your procedure)
- A list of all previous surgical procedures you have undergone, like for example: Removal of appendix, gallbladder, or any other part, of your body; surgical repair of any body part, such as hernia repair, perforation of bowel wall, etc.
What Preparations are needed, prior to the Procedure?
- The physician may evaluate the individual’s medical history to gain a comprehensive knowledge of the overall health status of the patient including information related to the medications that are being currently taken
- Some medications increase a person’s chances of bleeding and it may be recommended to discontinue them for a period of time, before the procedure is performed
- Blood tests may be performed to determine if there is a bleeding tendency or any other medical conditions that prevents the person from undergoing the procedure
- Do inform the physician if you are allergic to any local anesthetics, lidocaine, etc.
- Avoid application of any cosmetics, deodorant, or topical medicines on the area, prior to the procedure
- It is advisable to quit smoking and the use of any nicotine based products, for a while, before the surgery
- Consumption of alcoholic drinks must also be avoided for a period of time, as instructed
- The patient must avoid eating or drinking at least 8 hours prior to the surgical procedure, depending on when the procedure is arranged
- For persons suffering from diabetes, it is important that the blood sugar stays within the normal range; if not their diabetologist may have to control blood sugar by recommending insulin and/or a combination of oral medicines
What is the Consent Process before the Procedure?
A physician will request your consent for Total Hip Replacement procedure using an Informed Consent Form.
Consent for the Procedure: A “consent” is your approval to undergo a procedure. A consent form is signed after the risks and benefits of the procedure, and alternative treatment options, are discussed. This process is called informed consent.
You must sign the forms only after you are totally satisfied by the answers to your questions. In case of minors and individuals unable to personally give their consent, the individual’s legal guardian or next of kin, shall give their consent for the procedure.
What Tests are needed, before the Total Hip Replacement surgical procedure?
Prior to a Total Hip Replacement procedure, the patient has to undergo certain tests, such as:
- Routine blood and urine analysis
- X-ray of the hip joint
- Computerized tomography (CT scan)
- Magnetic resonance imaging (MRI)
- Joint aspiration
