The surgery itself lasts one to two hours
Hip replacement surgery typically takes between 60 and 120 minutes once you are in the operating room. The exact time depends on whether you are having a traditional open procedure or a minimally invasive approach, the complexity of your hip damage, and your surgeon's experience. A straightforward primary hip replacement — your first one — usually falls toward the shorter end. Revision surgery, where a surgeon replaces an implant that has already failed, often takes longer because scar tissue must be removed and the bone may need more work.
The surgeon makes an incision, removes the damaged bone and cartilage, and secures the new socket and stem into place. If your surgeon uses cement to hold the implant, that adds a few minutes. If the implant is press-fit (held by friction and bone growth), the procedure may be slightly faster. Blood loss is controlled throughout, and the incision is closed in layers.
Key Takeaways
- The actual surgery takes one to two hours, but you will be at the hospital or surgical center for four to six hours total because of preparation and recovery time.
- Minimally invasive techniques may shorten operating time but do not necessarily reduce overall recovery or hospital stay length.
- You will spend one to three hours in the recovery room waking from anesthesia before moving to a regular hospital bed or discharge area.
- Most people go home the same day or stay one night; length of stay depends on your age, overall health, and whether complications arise.
Total time from arrival to discharge
Plan to be at the hospital or surgical center for four to six hours on surgery day. You will arrive one to two hours before your scheduled procedure for check-in, blood work, and final paperwork. The surgical team will review your medical history, place an IV, and prepare you for anesthesia. You may be given a sedative to help you relax.
After surgery ends, you move to a recovery room (also called post-anesthesia care) where nurses monitor your vital signs, pain level, and nausea as the anesthesia wears off. This phase typically lasts one to three hours. Once you are alert and stable, you are moved to a hospital room or a discharge area if you are going home the same day. The entire process from arrival to leaving the building is usually four to six hours.
Hospital stay: same-day discharge or overnight
Most hip replacement patients go home the same day or stay one night. Same-day discharge is increasingly common for people in good overall health with no major complications during surgery. You must be able to walk with a walker or crutches, manage pain with oral medication, and have someone drive you home and stay with you for at least the first night.
An overnight stay is more likely if you are older, have other medical conditions, live alone, or if there were complications during surgery. Some surgeons routinely keep patients overnight for observation. If you stay, you will receive pain medication, physical therapy will begin, and nurses will monitor your incision and blood clots. You will typically be discharged the morning after surgery if everything is stable.
When minimally invasive surgery is used
Minimally invasive hip replacement uses smaller incisions — often two to three inches instead of four to six — and may reduce operating time by 15 to 30 minutes. However, the total time you spend at the facility is usually similar because preparation and recovery take the same amount of time. The main advantage is less tissue damage, which can mean less pain and faster early healing, not necessarily a shorter hospital stay.
Not all patients are candidates for minimally invasive techniques. Factors like bone quality, implant size, and surgeon training determine whether this approach is an option for you. Ask your surgeon whether they recommend it for your specific situation and what difference it would make in your recovery timeline.
What happens in the first few hours after waking
As you wake from anesthesia, you may feel groggy, nauseous, or cold. Nurses will give you oxygen if needed and pain medication through your IV. Your leg will be in a pillow or abduction wedge to keep your hip in the correct position. You will be encouraged to move your foot and ankle to prevent blood clots, even though your hip itself will be immobilized.
Physical therapy often begins within hours of surgery. A therapist will help you sit up, stand with support, and take a few steps with a walker. This early movement is crucial for preventing complications and starting the healing process. You will also be fitted with compression stockings or given blood-thinning medication to reduce clot risk. Pain is managed with medication, and you will be monitored closely for any signs of bleeding, infection, or other problems.
Factors that can extend your time at the facility
Complications during or after surgery can add hours or days to your hospital stay. Excessive bleeding, difficulty waking from anesthesia, or a drop in blood pressure may require extended monitoring in recovery. Some people develop nausea that takes time to settle, or their pain is harder to control initially. These situations usually resolve within a few hours but may delay discharge.
Your age and overall health also matter. Patients over 75 or those with heart disease, diabetes, or lung problems are monitored more carefully and may stay longer. If you live far from the hospital or have no one to help you at home, your surgeon may recommend an overnight stay even if you are medically ready to leave. Discuss your specific situation with your surgical team before the procedure so you know what to expect.
Preparing for the time commitment on surgery day
Arrange for someone to drive you to the facility and pick you up afterward — you cannot drive yourself home because of anesthesia. Plan for that person to stay with you for at least the first 24 hours. Wear loose, comfortable clothing that is straightforward to remove and put back on. Bring your insurance card, photo ID, and a list of all medications you take.
Do not eat or drink after midnight the night before surgery, unless your surgeon gives different instructions. Arrive early to allow time for check-in. Bring a phone charger and something to read or watch while you wait, though you will be sedated for much of the day. If you are staying overnight, bring toiletries, comfortable pajamas that open in the front, and any comfort items that help you relax.
Frequently Asked Questions
Can I go home the same day as my hip replacement?
Most people can go home the same day if they are in good health, have no complications, and can walk with information. You must have someone to drive you and stay with you overnight. Your surgeon will decide based on how you are doing in recovery, not on a set schedule.
What if I need a blood transfusion during surgery?
Blood loss during hip replacement is usually minimal and controlled. Transfusions are rare but may be needed if you lose more blood than expected or if your blood count drops significantly. If this happens, your hospital stay may be extended for monitoring, but the surgery itself does not take longer.
How long does it take to walk after hip replacement?
You will take your first steps with a walker or crutches within hours of surgery, often the same day. Walking will be slow and painful at first, but movement is encouraged to prevent clots and stiffness. Full, pain-free walking usually takes several weeks to months as you progress through physical therapy.
Will I be awake during the surgery?
No. You will receive general anesthesia, which means you are completely asleep and feel nothing during the procedure. A regional anesthetic (numbing your lower body) is sometimes used alongside general anesthesia. You will not remember the surgery.
What if my surgery takes longer than two hours?
If your surgery takes longer than expected, it usually means your surgeon encountered more damage or scar tissue than anticipated, or needed extra time to position the implant correctly. This does not necessarily mean something went wrong — it means your surgeon took the time needed to do the job properly. You will spend more time in recovery but usually still go home the same day or after one night.
