Why Does My Knee Hurt Going Up or Down Stairs?

If your knee hurts every time you climb stairs, walk downhill, or step down from a curb, you’re not alone.

Knee pain during stair movement is one of the most common complaints orthopedic specialists hear—and it can happen for several different reasons. Sometimes the pain is mild and annoying. Other times, it can feel sharp, unstable, or even make you avoid stairs altogether.

The good news is that identifying the source of the pain is often the first step toward finding relief.
Common Causes of Knee Pain on Stairs
Patellofemoral Pain Syndrome (Runner’s Knee)

One of the most common causes of knee pain on stairs is patellofemoral pain syndrome.

This occurs when the kneecap does not move smoothly over the joint as the knee bends. Climbing stairs increases pressure behind the kneecap, which can trigger pain.

Many patients describe it as:

• Pain in the front of the knee
• Aching after sitting for long periods
• Discomfort when squatting or using stairs
• Grinding or popping sensations

This condition is common in active individuals but can affect anyone.
Knee Arthritis

Arthritis can also make stairs painful.

As cartilage wears down inside the knee joint, bending the knee under pressure becomes more uncomfortable. Stair climbing places additional stress on the joint, especially when going down stairs.

Symptoms may include:

• Stiffness
• Swelling
• Crunching sensations
• Pain that worsens with activity
• Difficulty standing after sitting

Meniscus Injuries

The meniscus acts as a cushion inside the knee. A tear can cause pain, catching, locking, or instability—especially during stair movement.

Patients often notice:

• Sharp pain when twisting
• Clicking or catching
• Swelling
• Feeling like the knee may give out

Tendonitis or Overuse Injuries

Inflammation of the tendons around the knee can also create stair-related pain.

This is common in people who:

• Exercise frequently
• Spend time kneeling
• Walk long distances
• Increase activity too quickly

Pain may worsen after activity and improve with rest.
Why Going Down Stairs Often Hurts More

Many people notice that going down stairs hurts more than going up.

That’s because descending stairs places greater force on the kneecap and requires more control from the muscles supporting the knee joint. If the joint is irritated, unstable, or inflamed, the increased pressure can make symptoms worse.
When Should You See an Orthopedic Specialist?

Occasional soreness may improve with rest, but ongoing knee pain should not be ignored.

You should consider seeing a specialist if you experience:

• Persistent pain
• Swelling
• Instability
• Locking or catching
• Difficulty walking
• Pain that interferes with daily activities

Early evaluation can help identify the problem before it worsens.
Treatment Options for Knee Pain on Stairs

Treatment depends on the cause of the pain, but common options include:

• Physical therapy
• Strengthening exercises
• Activity modification
• Anti-inflammatory treatments
• Bracing
• Injections
• Advanced imaging if needed

In some cases, surgery may be recommended if conservative treatments are unsuccessful.
