What Is Jumpers Knee (Patellar Tendonitis)?
Jumpers knee occurs when the patellar tendon (located just below your knee cap) swells up due to inflammation. The patellar tendon is very important in sports because it connects your quads to your knees and helps you propel yourself off the ground when you jump. It also acts as a stabilizer muscle in the leg, ensuring that you remain balanced as you jump or move around. The patellar tendon therefore comes under a lot of stress, especially by athletes in sports that involve lots of jumping.
