Quick Answer
Psoriasis around the knee does not automatically prevent knee replacement, but the surgical team should assess skin near the planned incision, especially if it is inflamed, cracked, open, or may be infected. The team considers the skin’s location and condition, your overall health, and your medicines when planning next steps.
- Tell your orthopedic team where your psoriasis appears and whether it has changed recently.
- Skin directly over the planned incision may raise different concerns from a stable plaque elsewhere.
- Share a complete list of psoriasis medicines, other medicines, and supplements with your clinicians.
- Do not start, stop, or change psoriasis treatments without guidance from your clinicians.
- A flare or broken skin may prompt closer review or discussion of treatment and timing, but does not always mean surgery will be delayed.
- Report new wounds, spreading redness, warmth, drainage, or worsening pain near the knee promptly.
- If travelling for surgery, share your skin and medication information before departure and confirm how to contact the care team.
How Can Psoriasis Around the Knee Affect Preparation for Knee Replacement?
Psoriasis around the knee does not automatically prevent knee replacement, but your surgical team should assess any active plaques, cracks, open skin, or possible infection near the planned incision. The location and condition of your skin, your overall health, and the medicines you take all help clinicians plan safely. If the skin needs further evaluation, your team may discuss treatment or timing with you rather than applying a one-size-fits-all rule.
Before surgery, make sure the orthopedic team knows where your psoriasis appears and whether it has changed recently. A plaque on another part of your body may be different from inflamed or broken skin directly where the surgeon expects to make an incision. Do not try to quickly clear a patch by changing prescription creams or other medicines without advice. Your dermatologist, primary care clinician, and surgeon can help coordinate a plan that considers both your skin and your operation.
If you are travelling for knee replacement, share this information before departure, not just at the hospital check-in. Send an up-to-date medication list and, if requested, clear photographs of the affected area through the care team’s approved process. Confirm who will review a new flare and how you can contact that person while away from home. Clear communication helps avoid surprises and supports an individualized decision about proceeding, treating the skin, or reassessing the schedule.

Why skin near the planned incision matters
Before knee replacement surgery, the team checks the skin around the knee and the area where the incision is planned. They may look for active inflammation, thick or scaling plaques, cracks, bleeding, open sores, or signs that could suggest infection. These observations help the surgeon judge whether the skin is suitable for the planned approach and whether further assessment is needed.
Psoriasis is not the same as a skin infection, and having psoriasis does not by itself mean you cannot have surgery. Still, irritated or broken skin close to an incision deserves attention because the surgical team needs to consider skin integrity and infection prevention. The specific location matters. A stable patch away from the incision may raise different questions than a painful, fissured area directly over it.
Tell your team promptly about warmth, increasing pain, spreading redness, drainage, or a new wound near the knee. Such symptoms can have different causes, so do not assume they are simply a psoriasis flare. Your surgeon will consider the skin findings alongside your medical history and other health factors. That assessment, rather than the psoriasis diagnosis alone, guides the next step.
What your surgeon and dermatologist need to know
Describe where your psoriasis is active, when the current flare began, and whether the area is changing. Mention previous episodes of cracking, bleeding, or infection, especially if they involved the knee or lower leg. If a patch is close to the expected incision, say so directly. A simple body-location description can help the team focus its examination.
Bring a complete list of prescription medicines, non-prescription products, injections, and supplements you use for psoriasis or other conditions. Include topical creams and ointments, even if you apply them only occasionally. Note when you last used each product and who prescribed it. The team needs this context before advising you about skin care or medication changes.
Your orthopedic clinician may ask a dermatologist or primary care clinician to assess the skin or help manage a flare. If you are receiving care in another country, ask how records and medication names should be shared, and confirm that you can communicate in a language you understand. A translated medication list or recent dermatology notes can make handoffs clearer. Coordinated advice matters because the clinicians need to consider both skin treatment and surgical planning, rather than make decisions in isolation.
When a flare or broken skin may change the schedule
A flare near the incision may lead the team to examine the area more closely, ask for a dermatology opinion, or discuss whether the skin should be treated before surgery. Open skin or symptoms that could indicate infection also need timely clinical review. These steps are intended to clarify what is happening and whether the planned incision can be made through skin the team considers appropriate.
A psoriasis plaque does not automatically require postponing surgery, and not every plaque carries the same concern. Decisions depend on where the plaque is, whether the surface is intact, how active the inflammation appears, and whether there are signs of another skin problem. Your overall health and the reason for surgery also inform the discussion. The surgeon can explain how those factors apply to you.
If the team recommends changing the date, ask what needs to improve or be reassessed before a new date is chosen. If they do not recommend a delay, ask what changes should prompt another call. Report new wounds, spreading redness, drainage, or a rapid worsening of symptoms rather than waiting for the routine preoperative visit. This is particularly useful if you are travelling and may otherwise have limited access to your usual clinicians.
How to prepare your skin and review psoriasis medicines
Follow the skin-care instructions given by your surgical team. They may tell you how to wash the area and which products to avoid close to the operation, but instructions can differ according to your skin and the planned procedure. Do not scrub plaques, pick at scales, or apply a new product in an effort to make the skin look clearer before the assessment. Irritation can make it harder for clinicians to judge the area.
Do not start, stop, or change topical treatments, oral medicines, injections, or biologic medicines on your own. Whether a medicine should continue around surgery depends on the specific drug and your health situation, as well as the surgical team’s plan. Stopping treatment without guidance could allow symptoms to worsen, while continuing a medicine without discussing it may leave important questions unanswered. Ask the clinicians who prescribe and manage your medicines to coordinate their advice.
Keep your current medicine packaging or a reliable written list available, especially when travelling internationally, where brand names may differ. Use generic medicine names when possible and record the dose, schedule, and most recent dose. If you receive different instructions from different clinicians, tell them what you were advised and ask them to clarify the plan together. A shared plan is safer than trying to reconcile conflicting directions yourself.
Questions to take to your preoperative appointment
A short written list can help you cover skin concerns during a busy preoperative visit. Be specific about the plaque location and any recent change. You can ask:
- Does the skin near my planned incision need an additional review?
- What should I do if the psoriasis flares before surgery?
- Which cleansers, creams, or dressings should I use or avoid?
- Who should I contact about a new wound or possible infection?
- How should each of my psoriasis medicines be managed around surgery?
If your team wants a dermatologist’s input, ask who will arrange the review and how the recommendation will reach the orthopedic surgeon. International patients can also confirm how to share clinical records, whether an interpreter is available for important discussions, and whom to contact if symptoms change after arrival. Make sure you understand the instructions before leaving the appointment.
Write down the agreed plan, including any medicine instructions and the symptoms that should prompt a call. Contact the care team promptly if you notice a new open area, increasing redness, warmth, drainage, or worsening pain around the knee. If symptoms are severe or you feel acutely unwell, seek urgent medical assessment. These questions help turn a general discussion into clear steps for your own operation.

A: Not necessarily. Psoriasis alone does not automatically rule out knee replacement, but the surgeon will assess the skin near the planned incision and your overall health. Tell the team about active plaques, cracks, open areas, or recent changes so they can decide what evaluation or planning is appropriate.
Q: Will surgery be delayed if I have a plaque near the incision?
A: A plaque near the incision may need closer review, but it does not always mean surgery must be postponed. The decision depends on its location, whether the skin is intact, and whether there are signs of infection or another concern. Ask your surgeon what specific finding would affect your timing.
Q: Should I stop biologics or other psoriasis medicines before surgery?
A: Do not stop or adjust biologics, topical treatments, or other psoriasis medicines without instructions from your clinicians. The plan depends on the medicine, your health, and the operation. Share a complete medication list with your orthopedic team and the clinician who manages your psoriasis.
Q: What should I do if psoriasis flares before my operation?
A: Contact your surgical team and describe where the flare is, when it began, and whether the skin is cracked, bleeding, or painful. Do not try a new treatment or increase a dose unless a clinician advises you to. If the area is near the planned incision, mention that clearly.
Q: When should I contact my care team about knee skin changes?
A: Let the team know promptly about a new wound, spreading redness, warmth, drainage, or a rapid worsening near the knee. These changes can have different causes and need clinical assessment rather than self-diagnosis. Seek urgent care if symptoms are severe or you feel acutely unwell.
