Quadriceps Tendonitis: Knee Tendon Pain, Tendonitis and Tendinopathy
The quadriceps tendon is a patellar tendon with a strong fibrous band connecting the quadriceps to the patella and along with the infrapatellar tendon forming the front of the knee. When the quadriceps tendon becomes inflamed from overuse injuries, tendonitis can occur. This form of knee tendonitis can cause severe knee pain and require treatment. This article will discuss knee tendonitis, a common cause of knee pain.
The quadriceps tendon is designed to efficiently transfer energy from the muscles, through the patellar tendons to create a movement of the lower leg (extension) or slow down the movement of the body while the leg is fixed (eccentric), such as running.
Similar to other tendon injuries resulting in tendonitis or tendinopathy, knee tendon pain usually occurs from repeated stress on the quadriceps tendon that outpaces the ability to heal.
- The rapid increase in training volume or duration
- Limited ankle dorsiflexion or hip internal rotation
- The valgus collapse of the knee during physical activity
If there are limitations on other joints of the lower extremity then the quadriceps and its tendon will have increased torsional stress, which can lead to tendonitis.
