The surgery itself usually lasts 60 to 90 minutes

A total hip replacement operation takes between one and two hours from the moment the surgeon makes the first incision until the final stitch closes. Most procedures fall in the 60 to 90 minute range, though some run longer depending on bone density, scar tissue from earlier surgery, or anatomical variations that require the surgeon to adjust technique.

The actual time spent in the operating room is longer than the surgery time itself. You will be in the OR for roughly two to three hours total because the surgical team needs time to position you, prepare and drape the surgical field, and may support all instruments and implants are ready before cutting begins.

Key Takeaways

  • The surgical incision and implant placement takes 60 to 90 minutes, though the full operating room time is two to three hours.
  • Anesthesia administration and positioning add 30 to 45 minutes before the surgeon begins, and closing the incision adds another 15 to 20 minutes.
  • Previous hip surgery, bone quality issues, or obesity can extend operating time by 20 to 40 minutes beyond the typical range.
  • You will spend two to four hours in recovery before returning to your hospital room, separate from the time spent in the operating room.

What happens before the surgeon starts cutting

Before the incision, you spend 30 to 45 minutes in the operating room while the anesthesia team places your IV, monitors, and breathing tube. The surgeon and nurses position your body on the operating table—usually on your back or side depending on the surgical approach—and find you with positioning devices to keep you stable during the procedure.

Once you are positioned, the surgical team cleans your hip and surrounding area with antiseptic solution and drapes you with sterile sheets, leaving only the surgical site exposed. This preparation phase is essential for infection prevention and takes another 10 to 15 minutes. Only after all of this is complete does the surgeon make the first incision.

The steps that take up most of the operating time

The surgeon makes an incision, usually 8 to 10 inches long, and carefully separates the muscles and soft tissue to reach the hip joint. This exposure phase takes 15 to 20 minutes. The surgeon then removes the damaged cartilage and bone from the femoral head and acetabulum (hip socket), which requires careful work to preserve healthy bone and takes another 20 to 30 minutes.

Preparing the bone surfaces for the implants—shaping them to fit the new components precisely—accounts for another 15 to 25 minutes of operating time. The surgeon then inserts the acetabular cup into the socket, secures it (sometimes with screws), and positions the femoral stem into the thighbone. Inserting and aligning these components so the hip moves smoothly and bears weight correctly takes 15 to 20 minutes. Finally, the surgeon places the ball component on the femoral stem and tests the hip's range of motion and stability before closing.

Closing the incision and moving to recovery

Closing the incision layer by layer—muscle, fascia, subcutaneous tissue, and skin—takes 15 to 20 minutes. The surgical team then removes the drapes, transfers you to a recovery bed, and moves you to the post-anesthesia care unit (PACU). This transition takes another 10 to 15 minutes.

In the PACU, nurses monitor your vital signs, manage pain, and watch for any when ready complications as the anesthesia wears off. This recovery phase typically lasts two to four hours. You will not return to your hospital room until you are alert enough to follow commands, your pain is controlled, and your vital signs are stable.

Factors that can make surgery take longer

If you have had previous hip surgery on the same side, scar tissue can make it harder for the surgeon to access the joint, adding 20 to 40 minutes to operating time. Severe arthritis that has damaged a large amount of bone may require bone grafting or specialized implants, which also extends the procedure. Osteoporosis or very dense bone can slow the preparation and implant insertion steps.

Body weight, muscle mass, and anatomical variations also affect timing. A surgeon may need extra time to navigate around larger soft tissue or to adjust the surgical approach if your hip anatomy differs from the typical pattern. Complications discovered during surgery—such as unexpected fractures or implant fit issues—can add 30 minutes or more.

What to expect on the day of your surgery

Plan to arrive at the hospital two to three hours before your scheduled surgery time. You will check in, change into a hospital gown, and meet with the anesthesia team and surgical nurses. The surgeon will mark the surgical site and answer any last-minute questions.

From the time you leave your pre-op area to the time you return to your hospital room, plan on four to six hours total. This includes the two to three hours in the operating room, the two to four hours in recovery, and the time spent moving between areas. You will not be able to eat or drink until after you wake up, and you should arrange for someone to drive you home if you are discharged the same day (though many patients stay overnight).

Frequently Asked Questions

Can hip replacement surgery be done faster with newer techniques?

Minimally invasive approaches using smaller incisions can sometimes reduce operating time by 10 to 15 minutes compared to traditional open surgery, though the difference is modest. The time saved on exposure and closing is offset by the need for more precise instrument placement through a smaller opening. Surgeon experience with the technique matters more than the approach itself.

What if my surgery takes longer than expected?

Your surgical team will contact your family if the procedure is running significantly longer than anticipated. Minor delays of 15 to 30 minutes are common and usually do not indicate a problem. Longer delays may mean the surgeon encountered unexpected bone damage, implant fit issues, or anatomical variations that required adjustment.

Will I be asleep the entire time?

Yes. General anesthesia keeps you unconscious throughout the surgery and into the early recovery period. You will not wake up until you are in the post-anesthesia care unit, and you will have no memory of the procedure.

How long until I can go home after surgery?

If you are discharged the same day, you will leave four to six hours after arriving at the hospital. Many patients stay overnight for pain management and monitoring. Your surgeon will decide based on your age, overall health, and how well you are recovering in the when ready post-op period.

Does the type of hip implant affect how long surgery takes?

Different implant designs and materials require slightly different insertion techniques, but the difference in operating time is usually only five to ten minutes. Cemented implants may take slightly longer than press-fit implants, but both fall within the standard 60 to 90 minute range.
