What Is Patellar Tendonitis?
To understand patellar tendonitis, you must first understand the anatomy of the tendon. The patellar tendon [1] is a tough, and flexible band of tissue that connects the bottom of your kneecap to the top of your shinbone. Its major function is to transmit force from your quadriceps muscles [2] to straighten your knees. It is a 1.75 inch tendon that aids walking, jumping, and running.
The patellar tendon is located in a high-stress spot in your body, and it can suffer from severe damage. Patellar tendonitis is a condition that occurs when this tendon is overused. It is usually characterized by severe pain, irritation, and aches.
