Why Does My Knee Hurt Going Up or Down Stairs?

Most people don’t think much about climbing stairs—until it hurts.

If you’ve noticed pain in your knee when walking upstairs or downstairs, you’re not alone. This is one of the most common reasons people visit an orthopedic specialist. While the discomfort may start as a minor annoyance, it can also be an early warning sign of an underlying knee condition that shouldn’t be ignored.

The good news is that many causes of knee pain are highly treatable, especially when diagnosed early.

Why Do Stairs Cause Knee Pain?

Every time you climb stairs, your knees absorb several times your body weight.

Walking on level ground places about one and a half times your body weight across the knee joint. Climbing stairs increases that force to roughly three to four times your body weight, while walking downstairs can create even greater pressure as your muscles work to control your descent.

If any part of the knee isn’t functioning properly, those extra forces can quickly become painful.

Common Causes of Knee Pain on Stairs

Patellofemoral Pain Syndrome

Often called “runner’s knee,” this condition develops when the kneecap doesn’t glide smoothly within its groove.

You may notice:

• Pain around the front of the knee
• Discomfort after prolonged sitting
• Pain when climbing stairs
• Aching during squats

This is especially common among active adults and younger athletes.

Arthritis

Osteoarthritis gradually wears away the cartilage that cushions the knee joint.

As the cartilage becomes thinner, everyday activities—including climbing stairs—can become increasingly painful.

Symptoms often include:

• Morning stiffness
• Swelling
• Grinding or popping sensations
• Pain that worsens with activity

---

Meniscus Tears

The meniscus acts as a shock absorber inside the knee.

A tear can develop from a sports injury or simply from years of normal wear and tear.

Common symptoms include:

• Sharp pain
• Catching or locking
• Swelling
• Difficulty bending the knee
• Pain while twisting or climbing stairs

---

Chondromalacia Patella

This condition occurs when the cartilage underneath the kneecap begins to soften or wear away.

Many patients experience:

• A dull ache in the front of the knee
• Pain during stair climbing
• Discomfort after sitting for long periods
• Grinding sensations when bending the knee

Tendon Injuries

Inflammation of the quadriceps tendon or patellar tendon can also make stairs uncomfortable.

These injuries often affect people who:

• Run regularly
• Play jumping sports
• Increase activity too quickly
• Spend long hours on their feet

When Is Knee Pain Serious?

While occasional soreness after a strenuous workout may not be concerning, persistent pain deserves evaluation.

Schedule an orthopedic appointment if you experience:

• Pain lasting more than a few weeks
• Swelling
• Instability
• Locking or catching
• Difficulty walking
• Pain that interferes with daily activities

Early diagnosis often leads to simpler, less invasive treatment.

Treatment Options

Fortunately, surgery is not necessary for many patients.

Treatment may include:
