What is the Running Knee and How to Prevent It

Running Knee

If you’re a runner, you may have experienced a sharp pain in your knee that makes you stop in your tracks. This is called the running knee, and it’s a common injury among runners of all levels. But what causes it, and how can you avoid it?


The running knee, also known as patellofemoral pain syndrome or runner’s knee, is a condition that affects the cartilage under the kneecap. The cartilage acts as a cushion between the kneecap and the thigh bone, but when it gets irritated or damaged, it can cause pain and inflammation. The pain usually occurs when the knee is bent, such as when running, squatting, or going up or down stairs.



There are several factors that can contribute to the running knee, such as:


Overuse: Running too much, too fast, or too often can put stress on the knee joint and wear down the cartilage.


Weak muscles: If the muscles around the knee are weak or imbalanced, they can’t support the joint properly and may cause the kneecap to move out of alignment.


Poor biomechanics: If you have flat feet, knock knees, or other structural problems, you may have an abnormal gait that puts extra pressure on the knee.


Improper footwear: Wearing shoes that don’t fit well or don’t provide enough cushioning or stability can also affect your knee alignment and function.




The good news is that the running knee is not a serious injury and can be treated with some simple steps. Here are some tips to help you prevent and heal the running knee:


Rest: Take a break from running and any other activities that cause pain. You may need to rest for a few days or weeks, depending on the severity of your injury.


Ice: Apply ice to your knee for 15 to 20 minutes several times a day to reduce swelling and inflammation.


Anti-inflammatory drugs: You can take over-the-counter medications such as ibuprofen or naproxen to ease the pain and inflammation. However, don’t rely on them for long-term use, as they may have side effects.


Stretching: Stretch your quadriceps, hamstrings, calves, and hips regularly to improve your flexibility and prevent tightness.


Strengthening: Do exercises that target the muscles around your knee, such as squats, lunges, leg presses, and leg extensions. You can also use resistance bands or weights to increase the intensity. Start with low repetitions and gradually increase them as you get stronger.


Foam rolling: Use a foam roller to massage your thighs and calves. This can help release any knots or trigger points that may cause pain or stiffness.


Running technique: Pay attention to your form when you run. Keep your posture upright, your shoulders relaxed, and your arms swinging naturally. Land on your midfoot or forefoot, not your heel, and avoid overstriding or bouncing. Try to run on soft surfaces such as grass or dirt, rather than concrete or asphalt.


Running shoes: Choose shoes that fit well and suit your foot type and running style. You may need to replace your shoes every 300 to 500 miles, as they lose their cushioning and support over time. You can also consult a podiatrist or a running specialist to get custom orthotics or inserts if you have any foot problems.



The running knee is a common but manageable injury that can affect anyone who runs. By following these tips, you can prevent it from happening and recover faster if it does. Remember to listen to your body and don’t push yourself beyond your limits. Happy running!
