Why Does My Knee Hurt Going Up and Down Stairs? Causes, Treatment & When to See a Physiotherapist

Does your knee ache every time you walk up or down a flight of stairs? You're not alone. Knee pain while climbing stairs is one of the most common reasons people seek physiotherapy, affecting people of all ages—from active athletes to office workers and older adults.

Whether it's a dull ache, sharp pain, or a clicking sensation, discomfort when using stairs is often a sign that something isn't functioning properly within the knee joint or surrounding muscles.

At VanCity Physio, our experienced physiotherapists help patients identify the root cause of knee pain and create personalized treatment plans that relieve pain, restore movement, and prevent future injuries.

Why Does Stair Climbing Cause Knee Pain?

Walking on level ground places moderate force through your knees. However, going up or down stairs can increase the force through your knee joint to 3-6 times your body weight.

Descending stairs is often even more painful because your quadriceps muscles must work harder to control your body's movement while absorbing impact.

If any structure around your knee is irritated or weak, stair climbing quickly becomes uncomfortable.

Common Causes of Knee Pain on Stairs

1. Patellofemoral Pain Syndrome (Runner's Knee)

One of the most common causes of knee pain on stairs is Patellofemoral Pain Syndrome (PFPS).

This occurs when the kneecap (patella) doesn't move smoothly within its groove, creating irritation and inflammation.

Symptoms include:

  • Pain around or behind the kneecap
  • Pain when walking downstairs
  • Pain after prolonged sitting
  • Clicking or grinding sensations
  • Pain during squats

This condition is especially common among:

  • Runners
  • Cyclists
  • Active adults
  • Office workers who sit for long periods

2. Knee Osteoarthritis

As we age, the cartilage inside the knee gradually wears down.

This can cause:

  • Stiffness
  • Swelling
  • Pain during stairs
  • Difficulty standing from a chair
  • Reduced mobility

While arthritis cannot be reversed, physiotherapy can significantly reduce pain and improve function.

3. Patellar Tendonitis (Jumper's Knee)

Repeated jumping, running, or sports can overload the patellar tendon.

Symptoms often include:

  • Pain below the kneecap
  • Tenderness
  • Pain during stairs
  • Pain while jumping or squatting

Without treatment, tendon pain can become chronic.

4. Meniscus Injury

The meniscus acts as the knee's shock absorber.

A tear can occur from:

  • Twisting movements
  • Sports injuries
  • Age-related degeneration

Common symptoms include:

  • Sharp pain
  • Locking
  • Catching
  • Swelling
  • Difficulty using stairs

5. Muscle Weakness

Weak muscles are one of the biggest contributors to knee pain.

Weakness in the:

  • Quadriceps
  • Glutes
  • Hamstrings
  • Core

can cause the knee to absorb more force than it should, leading to pain over time.

6. Tight Muscles

Tight muscles can alter knee mechanics.

Common tight areas include:

  • Hip flexors
  • Hamstrings
  • Calves
  • IT Band
  • Quadriceps

Improving flexibility often reduces stress on the knee.

Why Does My Knee Hurt More Going Down Stairs?

Many people notice descending stairs hurts more than climbing up.

That's because walking downstairs requires your quadriceps muscles to slowly control your body weight.

This creates significantly more pressure behind the kneecap.

If your kneecap isn't tracking properly or the surrounding muscles are weak, pain often appears during this movement.

Signs You Shouldn't Ignore

Seek assessment if your knee pain includes:

  • Pain lasting more than 1–2 weeks
  • Swelling
  • Locking or catching
  • Knee giving way
  • Difficulty walking
  • Reduced range of motion
  • Pain that interrupts sleep
  • Pain that limits daily activities

Early treatment often prevents chronic pain.

How Physiotherapy Can Help

At VanCity Physio, we don't just treat the pain—we identify why it's happening.

Your physiotherapy assessment may include:

  • Movement analysis
  • Walking assessment
  • Stair assessment
  • Strength testing
  • Flexibility testing
  • Joint mobility assessment
  • Functional movement screening

Based on your assessment, your personalized treatment plan may include:

Manual Therapy

Hands-on techniques help improve joint mobility, reduce stiffness, and decrease pain.

Strengthening Exercises

Targeted strengthening for:

  • Quadriceps
  • Glutes
  • Hamstrings
  • Core
  • Hip muscles

helps improve knee alignment and reduce stress on the joint.

Stretching Program

Improving flexibility can restore normal movement and reduce pressure around the knee.

Balance & Movement Retraining

Proper movement patterns reduce unnecessary stress during walking, stairs, and exercise.

Education

You'll learn how to modify activities, improve posture, and safely return to exercise without aggravating your symptoms.

Can Knee Pain Go Away on Its Own?

Minor irritation may improve with rest.

However, if pain continues for more than a couple of weeks or keeps returning whenever you use stairs, it's important to determine the underlying cause.

Ignoring knee pain often leads to:

  • Increased inflammation
  • Muscle weakness
  • Reduced activity
  • Chronic pain
  • Longer recovery times

Early physiotherapy usually leads to faster recovery.

Tips to Reduce Knee Pain on Stairs

While waiting for your assessment, try these strategies:

Hold the handrail for support

Avoid taking stairs repeatedly if symptoms worsen

Wear supportive footwear

Apply ice for 10–15 minutes if swelling is present

Stay active with low-impact exercises like cycling or swimming

Avoid pushing through severe pain

Frequently Asked Questions

Why do my knees hurt only when going downstairs?

Going downstairs places greater force through the kneecap than walking on level ground. Weak muscles, poor knee alignment, or cartilage irritation can make this movement painful.

Is walking good for knee pain?

Yes. Gentle walking is often beneficial for knee health, provided it doesn't significantly increase your symptoms. A physiotherapist can help determine the right level of activity for your condition.

Can physiotherapy help avoid knee surgery?

In many cases, yes. Physiotherapy can reduce pain, improve strength, and restore movement, helping many people manage knee conditions without surgery.

How long does knee pain take to heal?

Recovery depends on the underlying cause. Mild conditions may improve within a few weeks, while tendon injuries or arthritis may require a longer rehabilitation plan. Following a personalized exercise program can help speed recovery.
