What is Patellar / Quadriceps Tendonitis vs Tear?

Patellar tendonitis and quadriceps tendonitis are terms used when discussing anterior knee pain related to inflammation. These conditions are related to overuse. Athletes, industrial laborers that squat, lunge, run, jump, push or pull can cause repetitive stress to this area creating unwanted inflammation and pain. In addition to the repetitive stresses, muscular imbalances, muscular tightness or weakness can be a contributing factor to these symptoms.

Tendonitis of the Patellar Tendon

Tendonitis of the Quadriceps Tendon

The knee is the largest and one of the most complex joints in the human body. The joint and its components function together to provide stability and power for activities of daily living and athletic movements. Muscles are connected to the bone by tendons. Muscles and tendons provide the motion of the joint. The quadriceps (thigh muscle) is connected to the patella (knee cap) by the quadriceps tendon. After crossing over the patella, the patellar tendon inserts onto the tibial tubercle (upper portion of your shin). These tendons promote knee extension – straightening of the knee.
