The timing depends on why you need the second surgery

You can have a second hip replacement as soon as your surgeon clears you, which typically ranges from a few months to several years after your first surgery. The timeline depends on whether you are having the surgery on your other hip (a staged bilateral procedure) or replacing the same hip again (a revision). Staged bilateral hip replacements—where you replace both hips in separate surgeries—usually happen 3 to 12 months apart. Revision surgery on the same hip, done because the original implant failed or wore out, can happen sooner if complications develop, but most surgeons prefer to wait at least 5 to 10 years to see how your first implant performs.

The key factor is not time alone, but your physical recovery and the reason for the second procedure. Your surgeon will assess your strength, range of motion, and overall health before scheduling. If you are having both hips replaced, the first surgery must heal enough that you can safely undergo anesthesia and rehabilitation again—usually a minimum of 3 months, though many surgeons recommend waiting longer to regain full strength.

Key Takeaways

  • Staged bilateral hip replacements (both hips) typically occur 3 to 12 months apart, depending on your recovery and surgeon preference.
  • Revision surgery on the same hip is usually delayed at least 5 to 10 years unless the implant fails early, because surgeons want to observe how long your first implant lasts.
  • Your surgeon will not schedule a second surgery until you have regained adequate strength and mobility from the first, which takes a minimum of 3 months.
  • Medical conditions like infection, blood clots, or poor wound healing can delay a second surgery beyond the typical timeline.
  • Insurance and surgical center availability may also affect scheduling, even after your surgeon clears you medically.

Staged bilateral replacements: replacing both hips separately

If you need both hips replaced, your surgeon will almost certainly do them in two separate surgeries rather than both at once. The standard interval is 3 to 12 months between surgeries, though some surgeons prefer 6 months as a middle ground. The exact timing depends on how quickly you recover from the first surgery and how motivated you are to move forward with the second.

The first surgery must heal enough that you can walk without a walker or cane, climb stairs, and perform basic daily tasks independently. You also need to have regained enough muscle strength to tolerate anesthesia and the physical demands of rehabilitation a second time. Most surgeons will not schedule the second surgery until you have completed physical therapy and reached a plateau in your recovery—usually 3 to 6 months after the first procedure. Waiting longer (8 to 12 months) gives your body more time to fully stabilize and reduces the risk of complications during the second surgery.

Some patients choose to wait longer than 12 months between surgeries because they want to live with one new hip and see how it performs before committing to a second major surgery. This is a reasonable choice, though it means living with pain or limited function in the unreplaced hip for a longer period.

Revision surgery: replacing a hip that has already been replaced

Revision surgery—replacing an implant that has failed or worn out—follows different timing rules than a first replacement. Most hip implants last 15 to 20 years or longer, so revision surgery is typically not needed until well into the future. However, if your implant fails early due to infection, loosening, or wear, your surgeon may recommend revision sooner.

If you need revision surgery because of infection or acute failure, your surgeon may want to operate within weeks or a few months to prevent further damage. If the implant is straightforward wearing out or loosening gradually, your surgeon will likely recommend waiting until the symptoms become severe enough to justify another major surgery. This is because each revision surgery is more complex than the previous one—the surgeon must remove bone cement or ingrown bone, which takes longer and carries higher risks. Waiting 5 to 10 years between your first implant and a revision gives your surgeon the best chance of a successful outcome and allows you to get maximum life from your first implant.

Your age and overall health also influence the decision. A younger patient might benefit from waiting as long as possible before revision, since they may need multiple revisions over their lifetime. An older patient with fewer years ahead might proceed with revision sooner if symptoms are affecting quality of life.

Medical factors that can delay a second surgery

Even if you are ready mentally and your surgeon has given initial approval, medical complications can push back your surgery date. Infection at the surgical site, blood clots, or poor wound healing from the first surgery must resolve completely before a second major surgery can proceed. Your surgeon will order imaging and blood work to confirm you are healed before scheduling.

Uncontrolled high blood pressure, diabetes, or heart conditions may also delay surgery until those conditions are better managed. Weight changes—either significant weight gain or loss—can affect how well your implant will function and may prompt your surgeon to recommend waiting until your weight stabilizes. If you develop anemia or other blood disorders after your first surgery, your surgeon may delay the second surgery until those issues are treated.

Pain or swelling that does not improve as expected can signal a problem with your first implant, which your surgeon will want to investigate before proceeding with a second surgery. In some cases, imaging like X-rays or MRI scans may be needed to rule out loosening or infection before the second procedure is scheduled.

Insurance and scheduling considerations

Your insurance company may have requirements about the timing between surgeries. Some plans require documentation that you have completed physical therapy and reached maximum benefit from the first surgery before approving the second. This is usually not a barrier—most surgeons' offices handle this paperwork—but it can add a few weeks to the scheduling process.

Surgical center availability also affects timing. If your preferred surgeon or facility has a long wait list, you may need to schedule your second surgery months in advance, even if you are medically ready sooner. Conversely, if you are flexible about timing and willing to take an earlier opening, you might have your second surgery sooner than you initially planned.

What to expect between your first and second surgery

During the months between surgeries, you will continue physical therapy to maintain and improve the strength and range of motion in your first hip. Your surgeon may recommend specific exercises to prepare your body for the second surgery. You should also manage pain in your unreplaced hip as best you can—your surgeon may recommend ice, anti-inflammatory medications, or activity modification to keep you comfortable while you wait.

It is normal to feel anxious about undergoing a second major surgery. Many patients find it helpful to talk with others who have had bilateral hip replacements, either through support groups or online communities. Your surgeon's office can often connect you with patients who have completed both surgeries and can share their experience.

Frequently Asked Questions

Can I have both hips replaced at the same time?

Most surgeons do not recommend simultaneous bilateral hip replacement because it increases the risk of blood clots, infection, and complications during recovery. You would be immobilized longer and face a much more demanding rehabilitation period. Staged surgeries (3 to 12 months apart) are safer and allow you to recover fully between procedures.

How long after my first hip replacement can I have the second one?

For staged bilateral replacements, the typical interval is 3 to 12 months, with 6 months being common. Your surgeon will not schedule the second surgery until you have regained adequate strength and mobility from the first, which takes a minimum of 3 months. For revision surgery on the same hip, most surgeons prefer to wait 5 to 10 years unless the implant fails early.

What if I develop complications after my first hip replacement?

Infection, blood clots, or poor wound healing will delay your second surgery until those issues are fully resolved. Your surgeon will order imaging and blood work to confirm you are healed. This may add weeks or months to your timeline, but proceeding with a second surgery before the first has fully healed increases the risk of serious complications.

Will my second hip replacement recovery be easier than the first?

Recovery from the second surgery is often similar to or slightly longer than the first, because your body has already been through major surgery once. However, many patients report that they know what to expect and feel more confident during rehabilitation the second time. Your physical therapist will tailor the program to your needs and your experience with the first surgery.

How long do hip implants last before revision is needed?

Most modern hip implants last 15 to 20 years or longer. Some patients never need revision surgery. If your implant fails early due to infection or mechanical problems, revision may be needed sooner. Your surgeon will monitor your implant during regular checkups and discuss revision timing if problems develop.
