What is Runner’s Knee?
If you’ve ever felt a dull, aching pain around your kneecap—especially after a run or a long day of climbing stairs—you might be dealing with what’s commonly known as Runner’s Knee. The medical term for it is Patellofemoral Pain Syndrome (PFPS), and it’s something many of us who are active have encountered at one point or another.
Runner’s Knee typically flares up during activities that involve repeated bending of the knee—like running, squatting, jumping, or even sitting for long periods. You might notice pain around the front of your knee, a popping or grinding sensation, or discomfort that gets worse the longer you stay seated.
So, how does it happen? It’s often a mix of overuse, poor movement mechanics, or muscle imbalances. If you ramp up your mileage too quickly or stick to uneven terrain, your knees might start to protest. Weak hips or core muscles can also make it harder for your knees to track properly, which puts even more strain on the joint.
You’re not alone—studies suggest that between 25% to 40% of runners will experience Runner’s Knee at some point. And it’s not just runners. Athletes in sports with repetitive knee movements or those who’ve had prior knee injuries are at risk too. Even the shape of your feet—whether you have flat feet or high arches—can influence your chances of developing this condition.
The good news? When you understand what causes Runner’s Knee, you’re in a better position to prevent it. Building strength, improving flexibility, and being mindful of your movement patterns can go a long way in keeping your knees healthy and your performance strong.
Are You at Risk for Runner’s Knee?
If you run regularly or stay active in other sports, it’s worth taking a closer look at the factors that could increase your chances of developing Runner’s Knee. We all want to stay injury-free, and knowing what puts your knees at risk is a smart first step.
Age plays a role. Young athletes going through growth spurts or older adults dealing with natural muscle loss and joint wear-and-tear can both be more vulnerable. Either way, it can change how your body moves—and your knees often take the brunt of it.
Your training habits matter too. If you’re a weekend warrior pushing hard after a week off, or if you’re increasing your training volume quickly without proper recovery, you might be putting too much stress on your knees. Going slow and steady gives your body time to adjust and strengthens your joints along the way.
Pay attention to your running surfaces. Hard concrete paths are rougher on your knees than softer trails or tracks. And don’t underestimate the power of good footwear. Shoes that fit well and offer the right support for your foot type and gait can help prevent biomechanical issues that lead to pain.
If you’ve had knee problems in the past—like tendinitis or a previous injury—that history might make you more likely to develop Runner’s Knee again. And your unique anatomy, like flat feet or unusually high arches, can also affect how forces are distributed when you move.
Understanding these risk factors helps you take a proactive approach—so you can keep doing what you love without unnecessary setbacks.
Why Preventative Exercises Matter?
If you’re aiming to stay healthy and pain-free while running, incorporating preventative exercises into your routine is one of the smartest moves you can make. Think of it as giving your knees the support system they deserve.
These exercises aren’t just about avoiding injury (though they definitely help with that). They’re about building strength in the muscles around your knee—especially your quads, hamstrings, and calves—so your joints can handle the impact and stress that comes with every stride.
Plus, working on flexibility can make a big difference too. When your muscles and joints can move through a full range of motion without restriction, your running form improves, and the chance of sprains or strains goes way down.
By regularly focusing on both strength and mobility, you’re not only protecting yourself from conditions like Runner’s Knee—you’re setting yourself up for better performance. A well-balanced body moves more efficiently, recovers faster, and holds up better over time.
Think of it as an investment: a little time spent on the right exercises now can save you from frustrating injuries later. And it means more time doing what you love—running pain-free and feeling strong.
Top 5 Exercises to Prevent Runner’s Knee
Want to give your knees the best support possible? These five exercises are easy to add to your routine and can make a big difference in keeping Runner’s Knee at bay.
- Straight Leg Raises
This one’s great for strengthening your quads without putting pressure on your knee. Lie on your back with one leg bent and the other straight. Slowly lift the straight leg to the height of your bent knee, hold for a second, then lower. Aim for 3 sets of 10–15 reps. - Clamshells
Your hips play a major role in keeping your knees aligned. Lie on your side with knees bent at 90 degrees. Keeping your feet together, lift your top knee without moving your pelvis. Do 3 sets of 12–15 reps on each side. - Wall Sits
These target your entire lower body. Slide down a wall until your knees are at a 90-degree angle and hold the position for 20–30 seconds. Repeat 3 times, and try to increase the duration over time. - Step-Ups
Find a sturdy step or bench. Step up with one foot and bring the other to meet it. Step down and repeat. This helps build quad and glute strength—key for healthy knees. Aim for 3 sets of 10–12 reps per leg. - Calf Raises
Strong calves help absorb impact and protect your knees. Stand on the edge of a step with your heels hanging off. Raise your heels as high as you can, then lower slowly. Do 3 sets of 15–20 reps.
Try to do these exercises 2–3 times per week. They don’t take long, and they can make all the difference in keeping your knees strong and resilient.
It is recommended to incorporate these exercises into your routine two to three times a week to effectively promote injury prevention and enhance running performance. Strengthening the surrounding muscles of the knee is a proactive approach towards sustaining a healthy running lifestyle.
