Why Your Knee Hurts More When Going Down Stairs

Why Your Knee Hurts More When Going Down Stairs

If you have knee pain, you’ve probably noticed this:

Going up stairs? Not great…
But going down stairs?

👉 That’s when it really hurts.

So why is that?

Down Stairs = More Pressure on the Knee

When you walk down stairs, your knee isn’t just supporting your body weight…

👉 It’s controlling and slowing it down.

That creates higher pressure inside the joint than walking on flat ground.

Muscles Have to Work Harder

Your quadriceps muscles are responsible for controlling your descent.

They work in a way called eccentric contraction (lengthening while under load).

If those muscles are:

• Weak
• Fatigued
• Not activating well

👉 The joint takes on more stress.

Why Arthritis Makes It Worse

With arthritis:

• Cartilage may be thinner
• The joint may be more sensitive
• Inflammation may already be present

So when pressure increases…

👉 You feel it more.

It’s Similar to Walking Downhill

If hills bother your knees, stairs will too.

Both require:

• Control
• Stability
• Load management

And both can expose weaknesses in the joint.

What This Usually Means

Pain going down stairs often signals:

• Reduced muscle support
• Increased joint irritation
• Decreased ability to handle load

👉 Not just “wear and tear.”

What Can Help

• Strengthening surrounding muscles
• Slowing your pace
• Using handrails
• Improving joint stability

Small changes can make a big difference.

The Takeaway

If going down stairs hurts more than going up, it’s usually because of increased pressure and control demands on the knee.

Understanding this helps explain why certain movements trigger pain more than others.

At Buffalo Arthritis & Joint Pain Center, we help patients explore non-surgical options designed to improve strength, stability, and comfort.

👉 Your knees should support you—not hold you back.
