Frequently asked questions

The things you’re
probably wondering.

Plain-language answers to everyday questions about knee replacement. No question is too small to bring to your care team.

Does pain medicine mean I should be pain-free?

Not necessarily. The Ascension Seton manual describes a goal of pain control that lets you participate in recovery. Tell the team both your pain level and what it stops you doing, such as sleeping, getting up, or exercising. Ask which medicines are scheduled, which are as needed, and whom to call if the plan is not working.

What if I go home with a nerve block or catheter?

A nerve block can temporarily numb part of the knee. If your team uses one, ask for written instructions on walking safely, what to expect as it wears off, and whom to call. If a catheter stays in place at home, confirm its care and removal plan, and your specific shower restrictions.

How should I use ice safely?

The Ascension Seton manual advises a fabric barrier between the skin and an ice pack. Ask your team how long and how often to use cold therapy, especially with numb skin or a cooling machine. Do not place ice directly on your skin or assume every device uses the same instructions.

Do I need to buy all the recovery equipment I see online?

Ask your physical or occupational therapist which items fit your needs and home. Confirm who supplies them, how to use them, and what you will owe before accepting or buying equipment. The manual discusses walkers and bathroom aids, but coverage and costs depend on your insurer and supplier.

Why is sleeping so difficult?

Pain, medicines, and changes in routine can interrupt sleep after knee replacement. Tell your team what is waking you and ask how your prescribed pain plan should work at night. Do not add sleep medicines or change doses without checking with a clinician or pharmacist.

How much swelling should I expect?

Swelling can be noticeable in the early weeks and may linger for months. Follow your team’s instructions for ice, elevation, and compression if prescribed. New or severe swelling, especially with calf pain, needs prompt medical advice. Do not assume every change is normal.

How much help will I need at home?

Plan for help with meals, transport, errands, and some daily tasks. The amount and duration vary with your mobility, home, and procedure. Before discharge, ask what you can safely do alone and how long someone should stay with you. Tell the team if that support is unavailable.

When can I drive again?

Your surgeon should clear you based on the operated leg, your control and reaction time, and your medicines. Do not drive while taking opioids or other medicines that impair alertness. A general week-by-week guide cannot tell you that you are ready.

Should I push through pain in physical therapy?

Rehabilitation can be uncomfortable, but uncontrolled or worsening pain deserves a conversation. Ask your therapist what discomfort is expected and what means you should stop. Follow the exercise plan you were given rather than adding repetitions or forcing movement on your own.

When can I shower or get the incision wet?

This depends on your dressing, wound closure, and surgeon’s instructions. Ask for an exact plan before going home. Do not soak the incision in a bath, pool, or hot tub until your team says it is safe. Call about new drainage or increasing redness.

Can the pain medicine cause constipation or nausea?

Yes. Opioid pain medicines can cause both, along with drowsiness and other side effects. Ask your care team about a prevention and treatment plan. Contact them if symptoms are troublesome, you cannot keep fluids down, or you are unsure what is safe to take.

Can I add an over-the-counter pain reliever?

Check with your clinician or pharmacist first. Some prescription pain medicines already contain acetaminophen, and some anti-inflammatory medicines may be unsuitable with blood thinners or certain health conditions. Have someone review your full medication list before combining products.

Why do I feel tired or emotional?

Surgery and recovery can leave you tired, frustrated, or less confident for a while. Allow room for rest and talk about how you are feeling. Ongoing low mood, significant anxiety, or fatigue that feels severe or is getting worse is worth discussing with your healthcare team.

Can I use stairs at home?

Ask a therapist to teach and watch your technique with the right aid and handrail. Tell them how many stairs you have and where the bathroom and bedroom are. Do not practise an unfamiliar technique without the supervision your team recommends.

Should I put a pillow under my knee?

Keeping the knee bent over a pillow can make it harder to regain straightening. Ask your therapist to show you how to support and elevate the leg for your situation, including at night. Follow their positioning instructions.

Is clicking in the new knee always a problem?

Some people notice clicking from implant components. Mention it to your team, especially if it is new or worrying. Clicking with new pain, swelling, instability, or trouble bearing weight needs medical advice rather than reassurance from an online guide.

Does this guide apply to ACL or meniscus surgery?

This guide focuses on knee replacement. Ligament reconstruction, meniscus repair, and other procedures can have different weight-bearing, brace, and movement restrictions. Ask for instructions for your exact operation rather than using the recovery stages here.
