Why Does My Knee Hurt Going Down Stairs?

If your knee hurts when walking down stairs but feels better on level ground, you're not alone. This is one of the most common complaints we hear at Apex Physical Therapy & Wellness.
Pain while descending stairs often means the structures around your kneecap are under more stress than they can currently tolerate. The good news is that identifying the cause early can help you recover without relying on injections or surgery.
Why Going Down Stairs Hurts More Than Going Up
Walking downstairs places significantly more force through the knee than walking on flat ground.
As you lower your body, your quadriceps muscles work to control your descent. This increases pressure between your kneecap (patella) and the thigh bone (femur).
If the joint, tendons, muscles, or cartilage are irritated, you'll often notice pain during this movement before other daily activities become uncomfortable.
The Most Common Causes
1. Patellofemoral Pain Syndrome (Runner's Knee)
This is one of the most common reasons people experience pain going downstairs.
Symptoms include:
Pain around or behind the kneecap
Pain with stairs
Pain after prolonged sitting
Pain during squatting
Patellofemoral pain often develops because the kneecap isn't moving efficiently due to muscle weakness or movement mechanics.
2. Arthritis
As cartilage wears down, the knee becomes less able to tolerate compressive forces.
Common signs include:
Morning stiffness
Swelling
Grinding or crunching
Pain during prolonged walking
Difficulty descending stairs
3. Patellar Tendinitis
Pain just below the kneecap may indicate irritation of the patellar tendon.
This condition is common in:
Runners
Basketball players
Volleyball athletes
Individuals who recently increased activity
4. Quadriceps Weakness
Weak quadriceps muscles make it difficult to control your body while walking downstairs.
Your knee may feel:
Weak
Unstable
Like it wants to give way
Fatigued after activity
5. Meniscus Injury
Although meniscus tears usually cause twisting pain, some people notice symptoms primarily when using stairs.
Other symptoms may include:
Clicking
Locking
Swelling
Pain with deep bending
How Physical Therapy Helps
Physical therapy focuses on identifying why your knee hurts—not simply treating the pain.
Treatment may include:
Strengthening the quadriceps
Hip and glute strengthening
Balance training
Walking and stair retraining
Manual therapy
Mobility exercises
Activity modification
Most patients notice gradual improvement as strength and movement quality improve.
Should You Keep Using Stairs?
In most cases, yes.
Avoiding stairs completely can lead to additional weakness.
Instead, your physical therapist may recommend:
Using the handrail
Taking one step at a time temporarily
Reducing activity during painful flare-ups
Performing strengthening exercises to improve tolerance
When Should You See a Physical Therapist?
Schedule an evaluation if:
Pain lasts longer than one to two weeks
Your knee swells regularly
The knee feels unstable
Pain limits work or exercise
You avoid stairs because of discomfort
Early treatment often leads to a faster recovery.
Frequently Asked Questions
Is knee pain going downstairs a sign of arthritis?
Not always. While arthritis can cause stair pain, younger individuals commonly experience symptoms from patellofemoral pain syndrome or tendon irritation.
Should I stop exercising?
Usually no.
Modifying your activities while continuing appropriate exercise often leads to better outcomes than complete rest.
Will I need surgery?
Most causes of stair-related knee pain respond well to conservative treatment, including physical therapy.
Surgery is generally reserved for more significant structural injuries or cases that fail to improve with non-surgical care.
