Knee Replacement Symptom Triage Flowchart & Red‑Flag Guide
Stop Guessing: Is This Knee Pain or Swelling “Normal” or a Red‑Flag?
In the weeks after knee replacement, every new ache, swelling, or warm patch can feel terrifying.
Is it just normal healing—or the start of an infection or blood clot?
Infections and blood clots are rare but serious, and patient‑education sites emphasise that acting early when red‑flag symptoms appear can help protect your new joint and your life.
Most hospital leaflets list long bullet lists of “normal” versus “abnormal” signs, but when you’re in pain, you don’t want paragraphs—you want a clear, simple “What do I do right now?” guide.
This free, print‑friendly Knee Replacement Symptom Triage Flowchart & Red‑Flag Guide gives you exactly that.

“Normal‑ish vs. concerning” guide for everyday symptoms
Examples of what is often expected in early recovery (swelling that eases with rest and ice, mild warmth around the knee, stiffness that’s worse after activity but gradually improving) versus patterns that should trigger a call to your surgeon within 24 hours (swelling or pain staying the same or worsening over a week, warmth/redness spreading instead of fading).
