Knee Pain When Walking Stairs: Causes, Treatment, and When to See a Physio

Knee pain when going up or down stairs is a very common concern, especially for people who walk regularly, exercise, or spend long hours on their feet. For many people in Adelaide, it’s one of the first signs that something isn’t quite right with how the knee is coping with daily load.

The reassuring news is that stair-related knee pain is rarely dangerous and, in most cases, responds well to the right guidance and treatment.

Why stairs often trigger knee pain

Walking on stairs places higher forces through the knee than level walking. Going downstairs in particular increases load on the kneecap and surrounding structures because the muscles must control your body weight as you lower yourself.

Knee pain on stairs usually reflects how load is being managed, rather than “wear and tear” or damage.

Common causes of knee pain on stairs

1. Patellofemoral pain (pain around or behind the kneecap)

This is one of the most common causes of stair-related knee pain.

People often describe:

• Pain behind or around the kneecap

• Discomfort going downstairs or downhill

• Symptoms after sitting for long periods

It’s linked to how the knee, hip, and ankle work together under load, not a single structural fault.

2. Tendon-related pain

The quadriceps or patellar tendon can become sensitive with:

• Sudden increases in walking, running, or gym work

• Repetitive stair use

• Reduced recovery time

Tendon pain is usually load-related and improves with the right strength progression.

3. Knee osteoarthritis (OA)

Knee OA can cause pain on stairs, particularly when:

• Strength has reduced

• Joint stiffness is present

• Activity levels have changed

Importantly, pain does not mean you should stop using your knee. Exercise is a core part of managing knee OA and helps maintain function and confidence.

4. Muscle weakness or control issues

Reduced strength in the:

• Quadriceps

• Gluteal muscles

• Calf muscles

can increase knee load on stairs. This is common after periods of reduced activity, injury, or pain-related avoidance.

5. Recent injury or flare-up

A recent fall, twist, or sudden increase in activity can temporarily make stairs uncomfortable. In many cases, this settles with appropriate management.

What often helps knee pain on stairs

1. Modify load, not eliminate movement

Avoiding stairs completely can lead to deconditioning. Instead:

• Reduce volume temporarily if pain is flared

• Use handrails during recovery

• Gradually rebuild tolerance

Movement is usually part of the solution.

2. Strengthen key muscle groups

Evidence consistently shows that progressive strengthening helps many forms of knee pain.

A physiotherapist may guide exercises targeting:

• Quadriceps

• Gluteals

• Calves

• Hip and knee control during functional tasks

These are tailored to your symptoms and goals.

3. Improve movement confidence

Pain can change how we move. Retraining stair technique and building confidence often reduces symptoms and fear.

4. Address contributing factors

This may include:

• Work or sport load

• Footwear

• Training errors

• Recovery strategies

There’s rarely one single cause—context matters.

When should you see a physiotherapist?

Consider seeking help if:

• Knee pain persists for more than 2–3 weeks

• Pain is worsening or limiting daily activities

• You’re avoiding stairs due to fear or discomfort

• Pain keeps returning despite rest

A physiotherapist can:

• Take time to understand your symptoms

• Assess strength, movement, and load tolerance

• Provide a clear, individualised plan

• Help you return to stairs and daily life confidently

A calm, evidence-based message

Knee pain on stairs is common, but it doesn’t mean your knee is “damaged” or that surgery is inevitable. In most cases, the knee responds well to thoughtful loading, strength, and reassurance.

If this sounds like you, a physiotherapist can help guide the next steps.
