Quick Answer
A negative-pressure dressing after hip replacement is a sealed dressing connected to a portable pump that applies controlled suction over a closed incision. Surgical teams use it selectively to help manage incision fluid and maintain a sealed environment; it does not guarantee prevention of complications or replace follow-up.
- The dressing is intended for a closed incision, not an open wound.
- Whether to use the dressing depends on the individual patient, surgical situation, and care plan.
- Keep the dressing in place for the period specified by your team, and do not remove or change it unless instructed.
- Device features, alarms, and showering rules vary, so follow the instructions for your specific pump and dressing.
- If the pump alarms or stops, check the device guide and contact your care team if the alert continues or you are unsure what to do.
- Contact your surgical team about worsening redness, increasing drainage, wound separation, fever, or worsening pain.
- A functioning pump does not rule out a wound problem, and an alarm alone does not establish one.
Negative-Pressure Dressings After Hip Replacement: Why Might One Be Used?
A negative-pressure dressing after hip replacement is a sealed dressing connected to a small pump that applies controlled suction over a closed incision. Your surgical team may choose it when they believe extra support for incision management is appropriate. It is not used for every hip replacement, and it cannot guarantee that infection or other wound problems will be prevented. The dressing also does not replace follow-up or assessment by your care team.
The device may look different from a standard dressing because it includes tubing and a portable pump. Depending on the product, the pump may run continuously or have indicators and alarms that signal a change needing attention. What you should do depends on the specific device and the instructions you received at discharge, so do not rely on general advice to override them.
If you are recovering away from the hospital, including after travelling for surgery, make sure you know whom to contact about device questions and incision changes. Ask for instructions in a language you can comfortably understand, and keep the device guide and discharge information accessible. Knowing what the dressing does, how to protect it, and when to call can make it easier to manage this part of recovery without trying to diagnose a wound yourself.

What the sealed dressing and pump do over your incision
Incisional negative-pressure wound therapy is a dressing system placed over a closed surgical incision. A sealed cover connects through tubing to a small pump, which creates controlled negative pressure, or suction. The dressing is designed for the incision surface rather than an open wound that needs a different wound-care plan.
The dressing may help manage fluid at the incision and maintain a sealed environment while the tissue heals. It does not close the incision itself, replace surgical closure, or show whether the deeper tissues have healed. Your clinician still needs to assess your recovery when indicated.
Compared with a conventional dressing, this system includes a pump that must remain connected and work as intended. Its appearance, controls, and alerts vary by product. Some systems have a canister, while others may collect fluid differently, so check your own device guide rather than assuming every component is the same.
Keep attending scheduled follow-up and report concerns even if the pump appears to be working normally. A functioning device cannot rule out a wound problem, and an alarm does not by itself establish that one exists. The dressing is one part of your postoperative care, not a substitute for clinical review.
Why your surgical team may select this dressing
A clinician may consider incisional negative-pressure therapy when there are particular concerns about healing or the incision. The decision is made for an individual patient and surgical situation. Your team can explain what factors influenced its recommendation in your case, without implying that a complication is expected.
Some hospitals use these dressings selectively, while others may follow different protocols. They are not required after every hip replacement. The fact that you have one does not necessarily mean something went wrong during surgery, just as not receiving one does not mean your incision is being overlooked.
Research has examined whether negative-pressure dressings affect wound complications in different surgical settings, but results and recommendations can depend on the patients and procedures studied. It is not responsible to treat the dressing as a guarantee against infection, fluid leakage, or other complications. Your usual incision checks and follow-up remain important.
If you want to understand the choice, ask what the dressing is intended to do, how long your team expects you to wear it, and what signs should prompt a call. Those questions are especially useful if you will be travelling after surgery or transferring care between providers. For a broader view of follow-up after treatment abroad, see guidance on comparing the first 90 days of care after hip replacement abroad.
What to expect during daily wear and recovery
Your team will tell you how long to keep the dressing on. Wear time varies with the device and your care plan, so do not remove it simply because it has been on for a certain number of days. Keep the dressing in place unless a clinician or the written instructions tell you otherwise.
The dressing should form a seal over the incision, with tubing leading to a portable pump. You may notice the pump running or feel a gentle pulling sensation, but do not change settings to make it feel different. Keep the pump secure and avoid tugging, bending, or trapping its tubing as you move around.
Showering rules are product-specific. Some devices or dressings may have restrictions, so check the instructions before getting the pump or dressing wet. Do not soak the incision in a bath or pool unless your care team has specifically cleared this. If the dressing lifts, becomes wet, or is damaged, contact the team for direction instead of patching or replacing it yourself.
If your recovery involves travel or care in another country, carry the device instructions and discharge notes with you. Confirm how to reach your surgical team and how a local clinician can contact them if needed. This practical handover can help avoid confusion about the dressing, particularly when device labels or care instructions are not in your preferred language.
What to do when the pump alarms or stops
An alarm can indicate different things depending on the pump. Possible alerts include a leak in the seal, a blockage, low battery, or a full canister when the system uses one. Some devices also use lights or sounds to indicate that therapy has stopped. Check the product guide to identify the alert on your specific model.
Follow the troubleshooting steps provided by your surgical team or device instructions. You may be asked to check that the tubing is not kinked or that the pump is charged, but only follow steps that apply to your system. If the alert continues, you cannot identify it, or you are unsure what to do, contact your surgical team or the named support contact.
Do not switch off the pump, dismantle the dressing, or disconnect tubing unless your care team specifically instructs you to do so. If the pump stops, tell the team how long it has been off if you know. Avoid trying to repair a leak with household materials, since this could interfere with the seal or conceal a problem.
A device alert is a reason to check instructions and seek help when needed, but it does not automatically mean the incision is infected. Conversely, no alarm does not prove the incision is healing normally. If the incision itself is changing, report that separately rather than focusing only on the pump.
Which incision changes should prompt medical advice?
Contact your surgical team promptly if redness around the incision is worsening, drainage is increasing, the wound edges appear to separate, you develop a fever, or pain is getting worse rather than following the pattern your team described. These changes can have different causes, and symptoms alone cannot confirm an infection. A clinician can decide whether the incision needs examination.
Do not wait for the next routine appointment if a concerning change is developing. Describe when it started, how it has changed, and whether the pump has alarmed or stopped. If you are away from the team that performed your surgery, use the contact plan in your discharge instructions and arrange local assessment when advised.
Seek urgent medical care for severe or rapidly worsening symptoms, particularly if you feel acutely unwell or the incision is changing quickly. If you cannot reach your surgical team and believe the situation is urgent, use your local urgent or emergency care service. This advice applies whether the dressing is on, has been removed by a clinician, or is no longer functioning.
People planning recovery across borders may want to review what follow-up problems after returning home could require readmission. Whatever your location, keep the operating team’s contact details and a copy of your care plan available. When in doubt about a new wound change, professional assessment is safer than trying to diagnose it from the dressing or a photograph.

Your request has been received!
Thank you. If you have hip X-ray, MRI, CT scan, diagnosis notes, medication history, injection records, physical therapy notes, or previous surgery records, please keep them ready. A HealthNode consultant will guide you through the next step.
A: No. Surgical teams use these dressings selectively, and practices differ between providers. Having one does not necessarily mean a complication is expected, and not having one does not mean your incision is receiving inadequate care. Ask your team why it was chosen for your situation.
Q: How long might I need to wear the dressing?
A: The expected wear time depends on your device and your surgical team’s plan. Keep it in place until you are told to remove it or have it changed. If it becomes loose, wet, damaged, or uncomfortable, contact the team for specific advice rather than changing it yourself.
Q: Can I shower with the dressing and pump?
A: Showering guidance varies by product, so check your device instructions and discharge plan first. Protect the pump and dressing as directed, and do not assume that a sealed appearance means the system can get wet. Avoid baths, pools, or soaking the incision unless your care team has cleared this.
Q: What should I do if the pump alarms or stops?
A: Check the device guide for the meaning of that specific light or sound and follow only the troubleshooting steps provided for your pump. Contact your surgical team if the alarm continues, the pump will not restart, or you are uncertain. Do not dismantle the system or disable it unless you are specifically instructed.
Q: Can I remove or change the dressing myself?
A: Do not remove or change it unless your surgical team has instructed you to do so. The dressing and pump may need to stay connected for the period set out in your plan. If it lifts, leaks, or is damaged, ask the team how to proceed rather than applying a replacement on your own.
Q: Which incision changes should prompt a call to my care team?
A: Call promptly about worsening redness, increasing drainage, wound separation, fever, or worsening pain. These symptoms need assessment but do not diagnose infection by themselves. Seek urgent care for severe or rapidly worsening symptoms, especially if you feel very unwell.
