Knee Hurts

Why Does My Knee Hurt Going Up or Down Stairs? Here's What Your Knee May Be Telling You

September 07, 2026•5 min read

Have you ever noticed that your knee feels fine while sitting, but the moment you walk up or down the stairs, you feel pain?

You are not alone.

Stair climbing can place a significant demand on the muscles and structures around your knee. For some people, the pain may be related to muscle weakness or poor movement control. For others, it may be associated with irritation around the kneecap, arthritis, a tendon problem, or a previous injury.

The important thing is this: knee pain on the stairs is a symptom, not a diagnosis.

Understanding when and where your knee hurts can provide useful clues about what may be contributing to the problem.

Why Do Stairs Make Knee Pain Worse?

Walking on level ground is different from climbing or descending stairs.

When you climb stairs, your leg muscles have to produce more force to lift your body upward. Your quadriceps, the muscles on the front of your thigh, play an important role in straightening and controlling your knee.

When you walk down stairs, your quadriceps have another challenging job. They must control your body as you lower yourself from one step to the next.

If the muscles around your knee and hip are not strong enough, or if your movement mechanics are not ideal, stair climbing may expose a problem that is less noticeable during regular walking.

Lack of muscle strength and flexibility can contribute to knee problems, while strengthening the muscles around the knee can improve stability and function.

Does Your Knee Hurt More Going Up or Going Down?

This small detail can actually be helpful when trying to understand your symptoms.

Knee Pain Going UP the Stairs

If going upstairs is particularly painful, your knee is being asked to produce more force as you push your body upward.

Pain around the front of the knee may sometimes be associated with patellofemoral pain, which involves the area around and behind the kneecap. This type of pain commonly becomes worse with activities such as climbing stairs, squatting, or sitting with the knee bent for long periods.

Pain below the kneecap may also occur with irritation of the patellar tendon. Patellar tendinopathy can cause pain during activities that place repeated stress on the tendon, including climbing stairs.

Knee Pain Going DOWN the Stairs

Going downstairs requires your muscles to control your body as you lower your weight.

This can be particularly challenging if your quadriceps are weak or if you have difficulty controlling the position of your knee.

Some people also experience pain related to osteoarthritis or other knee conditions that make activities such as stairs, squatting, or lowering into a chair more difficult.

So if you notice that going down the stairs hurts more than going up, don't automatically assume your knee is simply "getting old."

It may be telling you that something about your strength, mobility, or movement needs attention.

Don't Just Avoid the Stairs Forever

When something hurts, your first instinct may be to avoid it.

And if an activity is significantly increasing your pain, temporarily modifying it may be appropriate.

But avoiding stairs indefinitely doesn't necessarily address why the stairs hurt in the first place.

The goal should be to figure out what is contributing to the problem and then gradually restore your ability to perform the activity.

Depending on the cause, treatment may include:

  • Improving knee and hip strength

  • Restoring flexibility and mobility

  • Improving balance and stability

  • Retraining movement patterns

  • Modifying activities while symptoms settle

  • Gradually increasing your tolerance to stairs and other activities

For certain knee conditions, physical therapy may help reduce pain, improve strength, stability, flexibility, and movement.
