Outpatient Hip and Knee Replacement: Is It Safe and Right for You?
If I tell a patient, “You may be able to go home the same day as your hip or knee replacement,” I can usually see the reaction on their face.
Surprise. Sometimes disbelief.
A joint replacement is a major operation. So how could it possibly be safe to leave the hospital just a few hours later?
That is a very reasonable question.
The answer is that joint replacement has changed considerably over the past several decades. We have better anesthesia, better pain control, improved surgical techniques, and much better recovery protocols. Patients who once needed a lengthy hospital stay can now, when carefully selected, recover safely at home after outpatient joint replacement.
This is not about rushing patients out of the hospital. It is about helping the right patient recover in the right environment.
And that distinction matters.
The Evolution of Joint Replacement
Years ago, hip and knee replacement often meant several days in the hospital. Some patients stayed even longer. They needed help getting out of bed, managing pain, walking, and beginning rehabilitation.
Today, many of those early recovery steps can happen within hours.
We have learned that patients do not necessarily need to remain in a hospital bed simply because they have had a joint replaced. Once a patient is medically stable, comfortable enough to move, able to walk safely with assistance, and has appropriate help at home, recovering in a familiar environment can make a great deal of sense.
The growth of outpatient hip replacement and outpatient knee replacement reflects that change.
The American Association of Hip and Knee Surgeons (AAHKS) reports that outpatient total joint replacement has increased substantially in the United States. Its guidance emphasizes three things that have to work together: careful patient selection, well-designed rapid-recovery protocols, and a strong clinical team.
So when I discuss same-day surgery with a patient, I am not simply asking, “Can we send you home?”
I am asking a much more important question:
“Can you recover safely at home?”
What Makes “Same-Day” Surgery Possible Now?
Several advances have changed the way we approach joint replacement.
One is anesthesia.
Modern regional anesthesia and nerve blocks can provide effective pain relief around the hip or knee without necessarily leaving a patient heavily sedated for hours. Depending on the operation and the patient’s medical situation, these techniques can be combined with other medications to make the first part of recovery more comfortable.
Surgical technique has changed as well. Depending on the procedure, we can use approaches designed to minimize disruption to surrounding tissues. Less tissue trauma can help make early movement more manageable.
Then there is rehabilitation.
We no longer think of recovery as lying in bed until you feel completely normal. We want you moving safely as soon as your medical team says it is appropriate.
A patient may stand and walk with assistance within hours of surgery. You may practice getting into a chair, using the bathroom, walking with a walker, or going up and down stairs if that is part of your home environment.
That early movement is planned. It is not an afterthought.
This combination of anesthesia, surgical technique, pain management, and early rehabilitation is what makes same day joint replacement possible for selected patients.
The Safety Data: What the Science Says
Let me address the question most patients really want answered:
Is outpatient joint replacement safe?
For appropriately selected patients, current evidence supports outpatient total hip and knee replacement as a safe option when it is performed within a well-designed program.
AAHKS reviewed the available evidence and reported that studies have found no meaningful difference in overall complications, readmissions, or patient-reported outcomes between appropriately selected outpatient and inpatient patients. The organization also stresses that outpatient surgery is not appropriate for everyone.
A 2025 systematic review and meta-analysis of prospective studies likewise found no significant difference in readmission or complication rates between outpatient and inpatient total joint arthroplasty groups, although the authors noted that additional high-quality prospective research is still needed.
That does not mean outpatient surgery eliminates risk.
It doesn’t.
Blood clots, infection, bleeding, wound problems, dislocation after hip replacement, complications related to anesthesia, and other problems can still occur.
There are also potential advantages to getting home and moving sooner. You have less time exposed to the hospital environment, and early mobility is an important part of preventing complications associated with prolonged inactivity.
The key point is this: outpatient surgery is not automatically safer simply because it is outpatient. It can be safe when the patient, surgical procedure, recovery protocol, and medical team are all appropriate for it.
Are You a Good Candidate?
This is where the individual patient matters most.
There is no magic age at which you qualify—or do not qualify—for outpatient surgery.
When I evaluate someone for outpatient joint replacement in Scottsdale or anywhere else, I look at the whole picture.
Your medical health
We want medical conditions to be reasonably well controlled.
High blood pressure, diabetes, heart disease, lung disease, sleep apnea, and other conditions do not automatically rule out outpatient surgery. But they may change the plan.
Your medications, heart and lung health, blood pressure, blood sugar, weight, previous surgical history, and other medical factors all need to be considered.
Someone with serious medical problems who needs close monitoring may be better served by staying overnight.
Your support at home
This is easy to overlook.
You need a responsible adult who can take you home and help you during the early recovery period. You should not plan to be completely on your own immediately after surgery.
That support may involve helping with meals, medications, walking, bathing, and other everyday activities.
Your home environment
Your home should be reasonably safe.
Loose rugs, clutter, poor lighting, and difficult stairs can become problems when you are using a walker.
If you have several stairs immediately inside your front door, for example, we need to know that before surgery—not after you arrive home.
Your willingness to participate
This matters more than many people realize.
Outpatient surgery requires an active patient.
You need to follow your medication and exercise instructions, get up and walk as directed, attend therapy when prescribed, and communicate with your care team if something does not seem right.
You don’t have to be an athlete.
You do need to be prepared to participate in your recovery.
AAHKS recommends considering medical, social, and surgical factors together rather than using a single cutoff to determine who should have same-day discharge.
The Reality of Recovering at Home
Let’s be honest about those first 48 hours.
You will not feel completely normal.
Your hip or knee will be sore. Swelling is expected. You may feel tired. You may need help getting around. Your sleep may not be perfect the first night.
That does not mean something is wrong.
One advantage many patients appreciate is being able to recover in their own home. There is something reassuring about sleeping in your own bed, using your own bathroom, and having a family member nearby.
Pain control is a big part of making this possible.
When we talk about multimodal pain control, we mean using several methods together rather than relying on a large dose of one strong pain medication. Depending on your individual needs, this may include different medications, regional anesthesia or nerve blocks, local anesthetic techniques, ice, elevation, and movement.
The goal is not to promise that you will have no pain.
The goal is to keep pain controlled enough that you can breathe comfortably, rest, get up, and participate in your early rehabilitation while limiting unnecessary use of opioid medication.
AAHKS specifically identifies effective multimodal pain management as part of a successful outpatient joint replacement program.
Your care team will also give you clear instructions about medications, wound care, walking, exercises, blood-clot prevention, and when to call.
And if you are not ready to go home?
You stay.
That is not a failure of outpatient surgery. It is exactly why discharge should be based on your recovery rather than the clock.
A Surgeon’s Final Advice
If you are considering outpatient total knee replacement or outpatient total hip replacement, don’t make the decision based on the phrase “same day” alone.
Ask what that means for you.
Ask how your medical history affects the decision. Ask what happens if you are not ready to leave. Ask how your pain will be managed. Ask who will help you at home. Ask when you will start walking and what your first few days will look like.
Most of all, be honest with your surgeon.
Tell us about your health. Tell us about your home. Tell us if you are worried about managing stairs or if you will be alone after surgery. These details are not minor. They help us build a safer plan for you.
For some patients, ambulatory joint replacement and same-day discharge can be an excellent way to begin recovery. For others, an overnight hospital stay may be the better choice.
There is no prize for going home first.
As a surgeon, my goal is to help you get home when you are ready, with a clear plan, appropriate support, and confidence about what comes next.
The decision should be a partnership between you and your surgical team.
If you are thinking about hip or knee replacement, have that conversation before surgery. Ask questions. Share your concerns. Together, you can decide whether outpatient joint replacement is a safe and appropriate path for your recovery.

The official biography identifies Dr. Russo as a third-generation orthopedic surgeon specializing in total hip and knee replacement and states that he has performed more than 4,000 joint replacement procedures since completing fellowship training and joining his father in practice in 2017.
FAQs
Is outpatient joint replacement safe?
For appropriately selected patients, outpatient hip and knee replacement can be a safe option when the procedure is performed within a structured program with appropriate patient selection, pain control, mobility assessment, and follow-up.
Can you go home the same day after knee replacement?
Some patients can go home the same day after knee replacement, but eligibility depends on overall health, pain control, mobility, home support, and other individual factors.
Can you go home the same day after hip replacement?
Yes. Many appropriately selected patients undergoing anterior total hip replacement may be candidates for same-day discharge, although the decision is made individually.
What makes someone a good candidate for outpatient joint replacement?
Good candidates generally have manageable medical conditions, appropriate home support, a safe environment, and the ability to participate in early rehabilitation.
Is outpatient knee replacement safe for older adults?
Age by itself does not determine whether outpatient surgery is appropriate. Overall health, medical conditions, mobility, support at home, and the patient’s ability to recover safely outside the hospital are also considered.
How soon do you walk after outpatient joint replacement?
Many patients begin standing and walking with assistance within hours of surgery when medically appropriate. The exact timing depends on the procedure, anesthesia, and individual recovery.
What happens if I am not ready to go home?
If you do not meet the required safety and recovery milestones, your surgical team can recommend additional observation or an overnight stay. Going home should depend on your condition, not simply the planned discharge time.
