The quadriceps are a group of four muscles found on the anterior thigh. They work together to extend, straighten, the knee, and control knee flexion when you are on your feet. They play an important role in activities such as running, standing up from a chair, climbing stairs, jumping, squatting and kicking.
The quadriceps tendon attaches your quadriceps muscles to your kneecap (patella). It works to straighten your knee, which helps you walk, jump, and climb stairs. If the tendon becomes inflamed, it’s called quadriceps tendinitis or quadriceps tendinopathy. It’s often a result of repetitive movements like jumping or kneeling.
This overuse leads to tiny tears, which cause pain and swelling. The injury often affects athletes, however, any active person can develop quadriceps tendinopathy. The risk is higher if you suddenly increase your physical activity.
Pain is in the front of your knee, just above the kneecap. Usually, the pain is dull and gradually increases over time. The pain may get worse after sitting down for too long or jumping, squatting, and running.
