Patellar Tendonitis, or runners knee, is a common over-use injury that causes pain and stiffness in the front of the knee. Chronic pain can lead to physiologic changes in the structure of the patellar tendon. This new study from JOSPT shows increased micro-circulation of the patellar tendon after prescribed eccentric exercises. Eccentric exercises are lengthening contractions such as slowly lowering during a squat or slowly bending your knee from a fully straightened position. Eccentric exercise can more readily bring nutrition to the tendon and create a healing environment that will reduce pain and stiffness. This approach is very similar to the eccentric protocol that we use to treat achilles tendonitis. The key is in the exercise prescription-so give us a call!
