Why do my knees hurt going down stairs?

Descending loads the knee far more than climbing — the quadriceps work while lengthening to control the drop, which is demanding on the joint. Pain specifically going down usually points to the patellofemoral joint or to quadriceps weakness rather than damage. A hot, red, acutely swollen knee is different and needs medical review.

The pattern is diagnostic in itself. Pain going down but not up, worse after sitting for a long time, and worse on slopes, is one of the most common presentations we see — and one of the most responsive to strengthening.

What usually helps

  • Quadriceps strength, which is the single biggest lever and takes weeks rather than days
  • Hip strength, particularly the glutes, because a knee that collapses inward is often a hip that is not controlling it
  • Reducing sustained deep knee bend for a while — not stopping activity, but choosing which activity
  • Losing excess weight where relevant, since descending stairs loads the knee at several times body weight

When to get it looked at first

A hot, red, acutely swollen joint, or joint pain with fever, needs medical review before anything else. So does a knee that locks, gives way, or followed a specific injury.
