Understanding the procedure
๐ Overview
What this procedure is
Total hip replacement, also known as total hip arthroplasty, is a surgery where a damaged hip joint is replaced with an artificial one. The hip is a "ball-and-socket" joint. During the procedure, a surgeon removes the worn-out bone and cartilage and replaces them with new parts made of metal, ceramic, or very hard plastic.
The artificial joint, called a prosthesis, is designed to mimic the natural movement of a healthy hip. It usually consists of a socket that fits into the pelvic bone and a ball attached to a stem that fits into the thighbone. This helps the joint move smoothly again without the pain caused by bone rubbing against bone.
What it treats or fixes
This procedure is most often used to treat damage caused by different types of arthritis. Your clinician may suggest it if other treatmentsโlike physical therapy, walking aids, or medicationโno longer provide enough relief. Common conditions include:
- Osteoarthritis: Often called "wear-and-tear" arthritis, which damages the slick cartilage that covers the ends of bones.
- Rheumatoid arthritis: An immune system condition that causes inflammation and can erode the joint surface.
- Osteonecrosis: A condition where the blood supply to the ball part of the hip joint is limited, which may cause the bone to collapse or deform.
The main goal of the surgery is to reduce chronic pain that makes it hard to walk, climb stairs, or get in and out of chairs. It is also used to fix stiffness that limits your ability to move or lift your leg during daily activities.
How common it is & where it's done
Hip replacement is one of the most common and successful operations performed today. Hundreds of thousands of these procedures are done each year in North America. Because technology and surgical techniques have improved, many people find they can return to their favorite low-impact activities after they recover.
The surgery is typically performed in a hospital or a specialized outpatient surgery center. While many patients stay in the hospital for a day or two, some may be able to go home the same day of the procedure. Your care team will determine the best setting for you based on your overall health and the support you have at home.

โญ Key Patient Questions (Quick Answers)
Recovery: What to Expect
Recovery begins almost immediately after surgery. Your care team will likely encourage you to stand and take a few steps the same day. This early movement helps prevent stiffness and keeps your blood flowing. Most patients can return home within one to two days after the procedure.
Once home, you will likely work with a physical therapistโa specialist who helps you regain strength and movement through specific exercises. You may need to use a walker, cane, or crutches for several weeks. Your clinician may also suggest simple changes at home, like using a raised toilet seat or a stable chair with arms, to make moving around easier during the first few weeks of healing.
Risks & Possible Complications
While hip replacement is generally safe, all surgeries have some risks. Your surgical team takes many steps to prevent issues. Some possible complications include:
- Blood clots: These are clumps of blood that can form in the leg veins. Your clinician may prescribe blood-thinning medicine or special compression stockings to help prevent them.
- Infection: This can happen near the incision or deep in the tissue. You will likely receive antibiotics before and after surgery to lower this risk.
- Dislocation: This is when the new ball of the joint comes out of the socket. Following your therapist's movement guides helps keep the joint in place while it heals.
You should contact your clinician if you notice signs like a high fever, sudden calf pain, or unusual redness and drainage around your incision.
Outcomes & Long-Term Results
The main goal of a hip replacement is to reduce chronic pain and help you move more easily. Most people find they can return to favorite activities like walking, swimming, and biking without the deep ache they felt before surgery. Modern hip implants are very durable and often last 15 to 20 years or more for many patients.
To keep your new hip working well, your clinician may advise against high-impact activities, such as running or jumping. Regular, low-impact exercise is usually encouraged to keep the muscles around your hip strong and supportive, which helps the implant last as long as possible.
Emotional Support & Reassurance
It is completely normal to feel a mix of emotions, from anxiety before the procedure to occasional frustration during the first few weeks of physical therapy. Recovery takes time and patience. Many people find it helpful to talk with friends or family members who have had the surgery or to join a patient support group.
Focus on the small wins each day, like walking a little further or noticing your daily pain is fading. This surgery is one of the most successful procedures in medicine for improving quality of life. With the support of your healthcare team and loved ones, you can look forward to getting back to the activities you enjoy with much more comfort.
๐งฌ Why This Surgery Is Performed
Why doctors recommend it
Doctors usually suggest a total hip replacement when the hip joint is damaged and causes significant pain. The most common reason is osteoarthritis, which is "wear and tear" that breaks down the cartilage that cushions your bones. Other reasons include rheumatoid arthritis (an inflammatory condition) or osteonecrosis, which happens when the bone doesn't get enough blood supply.
Your clinician may recommend this surgery if:
- Hip pain limits your daily activities, such as walking or bending.
- Pain continues even while you are resting or trying to sleep.
- Stiffness in the hip makes it difficult to move or lift your leg.
- Other treatments, like physical therapy or pain medications, have not helped enough.
Urgent vs planned treatment
In most cases, a hip replacement is a planned (elective) procedure. This means you have time to discuss the options with your care team and prepare your home for recovery. You and your clinician might decide to schedule surgery when your symptoms begin to interfere with your quality of life.
Sometimes, the surgery is more urgent. This often happens if you experience a hip fracture, which is a break in the top part of the thigh bone. In these situations, a clinician may recommend surgery quickly to help you regain mobility and prevent complications from being immobile.
Goals of treatment
The main goal of a total hip replacement is to relieve the chronic pain that makes daily life difficult. By replacing the damaged bone and cartilage with artificial parts, the surgery aims to create a smoother, more stable joint.
Other important goals include:
- Improved mobility: Making it easier to walk, climb stairs, and get in and out of chairs.
- Increased strength: Allowing you to participate in low-impact exercises and activities.
- Better quality of life: Helping you return to the hobbies and routines you enjoy with less discomfort.
While results vary for everyone, many people find that a successful surgery allows them to move more freely for many years.
๐ฅ Who May Need This Surgery
Who may benefit
Total hip replacement is often considered when hip pain and stiffness make it hard to perform daily tasks. This surgery involves removing damaged bone and cartilage and replacing it with artificial parts. Your clinician may suggest this if you have osteoarthritis (the "wear and tear" of joint cartilage) or rheumatoid arthritis, which is an inflammatory condition that can damage the joint over time.
Other people who may benefit include those with osteonecrosis. This happens when the blood supply to the "ball" part of the hip joint is limited, causing the bone to collapse or flatten. If you find that your hip pain continues even while resting, or if it keeps you awake at night, you might be a candidate for this procedure.
Usually, surgery is discussed after other treatments have not provided enough relief. These treatments might include physical therapy, using walking aids like a cane, or taking anti-inflammatory medications. If these options no longer help you walk, bend, or climb stairs comfortably, a hip replacement may help improve your quality of life.
When it may not be the right option
While hip replacement is a common procedure, it is not the right choice for everyone. Your clinician may advise against surgery if you have an active infection in your body. Surgery during an infection could cause the new artificial joint to become infected, which is a serious complication that is difficult to treat.
Other health factors can also play a role. For example, if you have severe medical conditions that make general anesthesia or major surgery very risky, your care team might suggest continuing with non-surgical treatments. They will also look at the strength of your bones and muscles. If the bone is too weak to support an implant or if the muscles around the hip cannot function well, the surgery may not be as successful.
Finally, if your pain is mild and does not interfere with your daily life, surgery is usually delayed. Doctors often prefer to wait as long as possible to ensure the artificial joint lasts for the rest of your life, as these parts can wear down over many years.
Questions to ask your care team
Deciding to have surgery is a big step. It is helpful to bring a list of questions to your appointment to make sure you feel comfortable with the plan. Your care team can help you understand what to expect before, during, and after the procedure.
- What are the specific risks for someone with my health history?
- How long do you expect the artificial joint to last?
- What kind of physical therapy will I need after surgery, and for how long?
- How soon will I be able to return to activities like driving or walking for exercise?
- Are there any activities I should avoid forever after the surgery?
- What are the alternatives if I decide not to have surgery right now?
The procedure & preparation
๐ฅ What happens during the procedure
In the procedure room
When you arrive in the operating room, the surgical team will help you get into a comfortable position on the table. They will clean the skin around your hip with a special soap to help prevent infection. You will also have an intravenous (IV) line placed in your arm or hand to provide fluids and medicine during the surgery.
High-level steps
The surgeon removes the worn-out or damaged parts of the hip joint. This includes the "ball" at the top of the thigh bone and the "socket" in the pelvic bone. These are replaced with new, artificial parts called a prosthesis. The new parts are made of materials like metal, ceramic, or very hard plastic. They are designed to move smoothly and reduce pain.
The surgeon prepares the bone surfaces so the new parts fit securely. In some cases, a special bone cement is used to hold the parts in place. In other cases, the parts have a special coating that allows your natural bone to grow into them over time.
Anesthesia and pain control
Your clinician may use general anesthesia, which puts you into a deep sleep. Another common choice is a spinal block, which numbs the lower half of your body while you remain relaxed or lightly asleep. These methods help ensure you do not feel pain during the surgery.
Afterward, you may feel some numbness or a heavy sensation in your legs as the medicine wears off. Your care team will use various methods to manage discomfort, which may include oral medicines or injections near the hip to help with local pain control.
Monitoring and safety steps
Throughout the surgery, the team monitors your vital signs, such as your heart rate, blood pressure, and oxygen levels. They use sterile drapes and tools to keep the area clean and reduce the risk of germs entering the site. Your clinician may also give you antibiotics through your IV to further protect against infection.
Immediately after the procedure
You will be moved to a recovery room where nurses will watch you closely as the anesthesia wears off. You might feel sleepy, thirsty, or have a bit of a sore throat. It is normal to feel some soreness or pressure in the hip area as you wake up.
The staff will check your pain levels and help you stay comfortable. They may also encourage you to do simple breathing exercises or move your ankles to help with blood flow. Most patients are encouraged to stand or take a few steps with help shortly after the surgery to begin the healing process.
Typical procedure length
A total hip replacement usually takes about one to two hours to complete. The exact time can vary depending on your specific needs and the surgical approach used by your clinician. Your surgical team will keep your family or loved ones updated on your progress.
๐ง Different approaches doctors may use
Common approaches (open vs minimally invasive)
Surgeons can reach the hip joint from different angles to perform the replacement. The most common approaches are from the front (anterior), the side (lateral), or the back (posterior). Your doctor will recommend the specific approach based on your body structure and their surgical training.
There are generally two main techniques used to access the joint:
- Traditional surgery: This method uses one longer incision (cut). It provides the surgeon with a wide view of the hip joint to place the implant securely.
- Minimally invasive surgery: This technique uses one or two smaller incisions. The goal is to disturb less muscle and tissue, which may help reduce pain and allow for a faster recovery in some patients.
Not everyone is a candidate for minimally invasive surgery. Factors such as previous surgeries, bone shape, or body weight may make the traditional approach a safer and more effective option for you.
Partial vs total
In a total hip replacement, the surgeon replaces both main parts of the hip joint. The damaged ball at the top of the thigh bone (femur) is replaced with a prosthetic ball, and the socket in the pelvis (acetabulum) is lined with a durable cup. This is the standard treatment for conditions like osteoarthritis that affect the entire joint.
In a partial hip replacement (also called hemiarthroplasty), only the ball is replaced. The patientโs natural socket is left in place. This procedure is most often used to treat certain hip fractures where the socket is still healthy and intact.
Your clinician will decide between these options based on the health of your hip socket. Because arthritis usually damages both the ball and the socket, partial replacement is rarely used for treating arthritis.
Revision or repeat procedures
Modern hip implants are durable and often last 15 to 20 years or more. However, they are mechanical parts that can eventually wear out or loosen. If the implant becomes loose, infected, or painful over time, a second surgery known as a revision may be necessary.
During revision surgery, the doctor removes some or all of the original implant and replaces it with new components. This procedure is typically more complex than the first hip replacement and may take longer to perform.
Recovery from a revision procedure can vary and may be slower than your original recovery. Regular follow-up appointments with your surgeon are important to monitor the condition of your implant over the years.
๐งช How to prepare
Tests and imaging that may be done
Before your surgery, your care team needs to confirm that you are healthy enough for the procedure. You will likely have a pre-operative appointment with your surgeon or primary care doctor. During this visit, they will examine your hip to check the strength of the surrounding muscles and how well the joint moves.
Your clinician may order several standard tests, including:
- X-rays: These provide clear pictures of your hip bones to help the surgeon plan the replacement.
- MRI or CT scans: These are sometimes used if the surgeon needs to see the bone shape or soft tissues in greater detail.
- Blood and urine tests: These samples are checked to rule out active infections, anemia (low red blood cell count), or pregnancy.
- Electrocardiogram (EKG): This test checks your heart rhythm to ensure your heart is strong enough for anesthesia.
Medication adjustments
Your surgical team will review all the medications you take, including prescriptions, over-the-counter drugs, and vitamins. Because some substances can increase bleeding or interact with anesthesia, you may need to pause them for a short time.
Important: Only stop taking medicines if your clinician instructs you to do so. Common instructions may include:
- Blood thinners: If you take medication to prevent blood clots, you may be asked to stop taking it a few days or weeks before surgery.
- Anti-inflammatory drugs (NSAIDs): Pain relievers like aspirin, ibuprofen, and naproxen can increase bleeding risk and are often stopped before the procedure.
- Supplements: Certain herbal supplements can affect bleeding or heart rate and may need to be paused.
If you take insulin or heart medication, ask your doctor specifically about whether you should take your usual dose on the morning of the surgery.
Day-before and day-of instructions
Getting ready the day before surgery helps reduce stress and lowers the risk of complications. Your care team will provide a specific timeline, but general preparations often include a few key steps.
The day before surgery:
- Fasting: You will likely be told not to eat or drink anything after midnight. This is important to prevent nausea during anesthesia.
- Bathing: You may be instructed to shower with a special antibacterial soap (such as chlorhexidine) to kill germs on your skin and reduce the risk of infection.
- Packing: Pack a bag with loose, comfortable clothes, flat slip-on shoes, your insurance card, and a list of your medications.
The day of surgery:
- Arrival: Arrive at the hospital or surgical center early to fill out paperwork and meet with the anesthesiologist.
- Transportation: You will not be allowed to drive immediately after surgery. You must arrange for a friend, family member, or care service to drive you home when you are discharged.

โ ๏ธ Risks & Possible Complications
General surgical risks
Like any major operation, hip replacement surgery carries some general risks. Your surgical team takes many precautions to keep you safe, but it is helpful to be aware of potential issues. These risks are similar to those found in other orthopedic surgeries.
- Reaction to anesthesia: Some patients may feel nauseous or have a reaction to the medication used to put them to sleep or block pain.
- Infection: Bacteria can enter the wound site. This can happen superficially on the skin or deeper around the new artificial hip.
- Blood clots: Clots can form in the leg veins (deep vein thrombosis) due to decreased movement after surgery. In rare cases, these can travel to the lungs.
- Bleeding: While some blood loss is expected, excessive bleeding is uncommon.
Procedure-specific complications
There are also risks specific to the hip joint itself. While serious problems are rare, your surgeon will check for these issues during your recovery to ensure your new hip is functioning correctly.
- Dislocation: The ball of the new joint can come out of the socket. This is most likely to happen in the first few months while the tissues are healing.
- Leg length changes: Sometimes one leg may feel slightly longer or shorter than the other. This is often done intentionally to ensure the hip is stable and the muscles are tight enough to hold it in place.
- Fracture: Healthy bone around the implant can sometimes crack during the surgery while the new parts are being fitted.
- Loosening or wear: Over many years, the new joint may wear down or become loose from the bone.
- Nerve injury: Rarely, nerves near the implant may be stretched or injured, causing numbness or weakness. This often improves over time.
How complications are treated
Most complications can be managed successfully if they occur. Your care team focuses heavily on prevention and early treatment. To prevent blood clots, your clinician may prescribe blood-thinning medication and compression stockings. They will also encourage you to move and walk soon after surgery to keep blood flowing.
If an infection occurs, it is typically treated with antibiotics. Superficial infections may only need oral medication, while deeper infections might require a procedure to clean the area or replace parts of the implant.
Mechanical issues also have specific treatments. If the hip dislocates, a doctor can usually put it back in place without surgery, followed by wearing a brace to let it heal. For leg length differences, a shoe lift or physical therapy can often help balance your walking. If the implant becomes loose or wears out after many years, a second surgeryโcalled a revisionโmay be recommended to replace the old parts.
๐ Medications Commonly Used
Pain control medicines
Managing pain is a key part of your recovery. Your care team often uses a "multimodal" approach. This means using different types of medicine together to provide better relief with fewer side effects. This helps you start moving and participating in physical therapy sooner.
Your clinician will tailor this plan to your specific needs. Common options include:
- Acetaminophen: Often used to reduce pain and fever.
- Non-steroidal anti-inflammatory drugs (NSAIDs): Medicines like ibuprofen or naproxen that help reduce swelling and pain.
- Opioids: Stronger pain relievers that may be used for a short time for more intense pain.
It is important to discuss any allergies or other medications you take with your care team. This helps them avoid harmful drug interactions and ensures the plan is safe for you.
Antibiotics
To help prevent infection at the site of your new hip, your surgical team will likely give you antibiotics. These are medicines that kill or stop the growth of harmful bacteria.
Usually, these are given through an intravenous (IV) line just before the surgery starts. Your clinician may continue them for a short period after the procedure. They will check your medical records for any history of antibiotic allergies to ensure the medicine is safe for you.
Blood thinners and clot prevention
After a hip replacement, your blood flow may slow down while you are less active. To help prevent blood clots from forming in your legsโa condition called deep vein thrombosisโyour clinician may prescribe blood thinners, also known as anticoagulants.
Commonly used options include:
- Aspirin: Often used in lower-risk cases to help keep blood moving.
- Prescription pills or injections: Stronger medicines that interfere with the body's clotting process.
You may need to take these for several weeks after you go home. Your care team will monitor you closely, as these medicines can increase the risk of bleeding. Always tell your clinician if you notice unusual bruising or have other safety concerns.
๐ When to Seek Medical Care After Surgery
Emergency warning signs
While serious complications are rare, they require immediate attention. Go to the emergency room or call 911 if you experience signs of a blood clot in your lungs (pulmonary embolism). These signs may include:
- Sudden shortness of breath or difficulty breathing
- Chest pain or pressure
- Coughing for no apparent reason
You should also seek immediate help if you suspect your new hip joint has dislocated (popped out of place). Signs of dislocation often include:
- Sudden, severe pain in the hip
- Inability to move your leg
- The leg appearing shorter or turning outward abnormally
Call your surgeon or clinic ifโฆ
Contact your care team right away if you notice signs of an infection or a blood clot in your leg. Catching these issues early helps ensure a smooth recovery. Your clinician may want to see you if you have:
- Fever: A temperature higher than 100.4ยฐF (38ยฐC), or shaking chills.
- Wound changes: New redness, swelling, or drainage (fluid or pus) coming from your incision.
- Leg clot signs: Pain, tenderness, or redness in your calf or leg that is unrelated to your incision.
- Uncontrolled pain: Pain that does not get better after taking your pain medicine.
Expected vs concerning symptoms
Recovering from hip replacement takes time. It is normal to have some pain, swelling, and bruising around the hip and thigh. For most people, this discomfort slowly improves as the body heals. Mild swelling in the leg is also common and often helps if you elevate the leg or use ice as directed by your surgeon.
However, symptoms should not get worse over time. It is concerning if swelling increases suddenly or does not go down when you rest and elevate the leg. Likewise, while the incision may be tender, it should stay clean and dry. If the wound starts leaking fluid or becomes hot to the touch, let your medical team know.
๐ฎ Outcomes & Long-Term Outlook โญ
Alternatives & decisions
๐ Alternatives or Non-Surgical Options
Non-surgical treatments
Before suggesting surgery, your clinician may recommend several non-surgical options to help manage hip pain and improve your mobility. These treatments are often the first step in care and aim to reduce inflammation (swelling) and strengthen the joint.
- Physical therapy: Specific exercises can help strengthen the muscles around your hip, which may take some pressure off the joint itself.
- Weight management: Losing even a small amount of weight can significantly reduce the stress placed on your hip joint during daily activities.
- Medications: Your clinician may suggest over-the-counter pain relievers or nonsteroidal anti-inflammatory drugs (NSAIDs) to help manage discomfort and swelling.
- Walking aids: Using a cane, crutches, or a walker can help improve your balance and reduce the weight your hip has to carry.
- Injections: In some cases, your clinician may recommend steroid injections directly into the joint to provide temporary relief from severe inflammation.
Watchful waiting
Watchful waiting is a period where you and your clinician monitor your symptoms without starting a new or aggressive treatment. This approach is often used when hip pain is mild or only happens during certain activities. It allows you to see if the condition stays the same or if it begins to interfere more with your life.
During this time, you might be encouraged to try low-impact activities, such as swimming or cycling, which keep the joint moving without the heavy impact of running or jumping. Keeping a record of when your pain occurs can help your clinician decide if your treatment plan needs to change in the future.
When surgery becomes the best option
Surgery is typically considered when non-surgical treatments no longer provide enough relief to maintain your quality of life. If your hip pain persists despite trying therapy and medication, your clinician may discuss a total hip replacement as the next step.
Common signs that it may be time for surgery include:
- Pain that limits your ability to perform basic daily tasks, such as walking, bending, or getting dressed.
- Stiffness that makes it difficult to lift your leg or move comfortably.
- Pain that continues even while you are resting or trying to sleep at night.
- Inadequate relief from physical therapy or pain-relieving medications.
The decision to move forward with surgery is usually based on how much the hip condition affects your daily function and whether other options have failed to provide lasting comfort.
Reference & resources
โ Common Misconceptions
๐งพ Safety & medical evidence
Evidence overview
Total hip replacement is widely considered one of the most successful surgeries in modern medicine. Doctors have performed this procedure for decades to help people suffering from severe hip pain and stiffness. Medical research consistently shows that for most patients, replacing a damaged hip joint leads to significant pain relief and improved ability to move and walk.
Studies indicate that modern hip implants are durable. While no artificial joint lasts forever, evidence suggests that many implants function well for 15 to 20 years or longer. This long-term success allows many people to return to daily activities and low-impact exercises, such as swimming or biking, that were previously painful.
Safety notes and individualized care
While hip replacement is generally safe, every surgery carries some risk. Your healthcare team follows strict safety protocols to help prevent complications. Common safety considerations include:
- Blood clots: To lower the risk of clots forming in the legs after surgery, your clinician may prescribe blood-thinning medication, support stockings, or compression devices.
- Infection: Antibiotics are typically given around the time of surgery to reduce the chance of infection at the incision site or around the new joint.
- Dislocation: In the early stages of recovery, there is a small risk of the ball of the new joint popping out of the socket. Your physical therapist will teach you specific movements to avoid while your muscles heal.
Other potential risks, though less common, include injury to nearby nerves or a feeling that one leg is slightly longer or shorter than the other. Your surgeon plans the procedure carefully to minimize these issues. Recovery is highly individual; factors such as your age, weight, and overall health (including conditions like diabetes) affect how quickly you heal. Your doctor will create a care plan tailored to your specific needs.
