Why Does the Front of My Knee Hurt? Common Causes and How Physical Therapy Can Help

If the front of your knee hurts when you squat, run, climb stairs, get out of a chair, or sit for a long time, you are not alone.

Front of knee pain—often called anterior knee pain—is one of the most common knee problems we treat in physical therapy.

One of the most important things to understand is that where you feel pain does not necessarily tell us why you have pain.

Two people can have pain in almost exactly the same place and need very different treatment. That is why good physical therapy should do more than give everyone with knee pain the same handful of exercises.

What Causes Pain in the Front of the Knee?

Several conditions can cause or contribute to pain around the front of the knee, including:

• Patellofemoral pain

• Patellar or quadriceps tendon irritation

• Osteoarthritis

• Meniscus injuries

• Irritation of the fat pad or other structures around the kneecap

• Weakness or poor control of the hip, knee, ankle, or trunk

• A sudden increase in running, jumping, lifting, or other activity

Sometimes imaging identifies a structural change. Other times, an MRI or X-ray does not completely explain why the knee hurts.

A good physical therapy evaluation looks beyond the painful area to determine what is preventing your knee from tolerating the activities you want to perform.

Step 1: Calm Down the Irritated Knee

The first goal is to get your knee calm enough that you can begin rebuilding its capacity.

We look at what aggravates your symptoms, what makes them feel better, and how much activity your knee currently tolerates.

That doesn't necessarily mean completely resting.

It may mean temporarily modifying running mileage, squat depth, stairs, jumping, cycling resistance, or another activity while using hands-on treatment and exercise to reduce symptoms.

Step 2: Restore Normal Mobility

Next, we look beyond just the knee.

Your knee needs adequate motion, but so do your hips and ankles. Restrictions at surrounding joints can change how you squat, walk, run, climb stairs, and land.

The goal is to restore the mobility necessary for your specific activities.

Step 3: Improve Movement and Control

You can have enough flexibility and still have difficulty controlling your leg.

We look at how you control your hip, knee, ankle, foot, and trunk during movements such as:

• Squatting

• Stepping down

• Single-leg balance

• Running

• Jumping and landing

• Cutting and changing direction

This is where rehabilitation starts progressing from simply treating a painful knee to improving how your entire body handles load.

Step 4: Get Strong—Really Strong

Strength is one of the most important pieces of successful knee rehabilitation.

Depending on what we find, treatment may focus on the quadriceps, hamstrings, glutes, calves, and other muscles throughout the lower extremity.

And simply being able to perform an exercise isn't the same thing as being strong enough.

At Summit Physical Therapy, we use VALD strength testing technology when appropriate to objectively measure strength and compare your injured leg with your other leg and established benchmarks.

Instead of guessing whether you're getting stronger, we can measure it.

Step 5: Build Strength Into Functional Movements

Once local strength improves, we progressively load the movements you actually need.

For one person, that might mean getting up and down stairs comfortably.

For another, it might mean heavy squats.

For a runner, it may mean developing the single-leg strength necessary to repeatedly absorb force over thousands of steps.

Your rehabilitation should eventually look like preparation for your life—not just a collection of knee exercises.

Step 6: Develop Power

Strength is essential, but active people and athletes often need more than strength.

They need to produce and absorb force quickly.

As symptoms improve and strength returns, rehabilitation can progress toward faster movements and power development.

This becomes especially important for runners and athletes trying to return to higher-level activity.

Step 7: Jump, Land, and Change Direction

If your goal involves running, tennis, pickleball, basketball, soccer, skiing, or another dynamic sport, your rehabilitation shouldn't stop because you can perform a pain-free squat.

We progressively introduce jumping, landing, hopping, acceleration, deceleration, and change-of-direction work when appropriate.

At Summit Physical Therapy, we can use VALD ForceDecks to objectively assess force production, jumping performance, and side-to-side differences during this stage of rehabilitation.

Step 8: Build Endurance and Durability

Being able to do something once isn't the same as being able to tolerate it repeatedly.

Your knee might feel great for the first mile and hurt at mile three. You might tolerate ten squats but develop symptoms during a full workout.

The later stages of rehabilitation should build your ability to tolerate the volume, repetition, and fatigue of your actual activities.

Step 9: Get Back to What You Actually Want to Do

This is the part that matters.

Your goal probably isn't to become good at physical therapy exercises.

It might be to run without thinking about your knee. Play tennis three times per week. Ski with your family. Lift heavy weights. Walk around Europe. Or simply climb the stairs without pain.

Your rehabilitation should progressively prepare you for that goal.

When Should I See a Physical Therapist for Front of Knee Pain?

Consider having your knee evaluated if the pain is persistent, keeps returning, limits your activity, or causes you to repeatedly modify things you want to do.

You don't necessarily need to wait until the pain becomes severe.

Understanding why your knee isn't tolerating a particular activity allows us to develop a plan to address the underlying limitations rather than simply waiting for the pain to disappear.
