My son had this diagnoses verfied by ultra sound. Eccentric exercise is all they believe in...which is making him worse..
Tendinosis is an accumulation over time of small-scale injuries that don't heal properly; it is a chronic injury of failed healing. Although you can't see the tendinosis injury on the outside of your body, researchers have seen what the injury looks like on the cellular scale by viewing slides of tendons under the microscope. (The microscopic changes in the tendon are described on the page The Tendinosis Injury, and the difference between tendinosis and tendinitis is described below in the section on terminology.) Tendinosis can occur in many different tendons, with some of the most common areas being the hand, wrist, forearm, elbow, shoulder, knee, and heel.
Some studies have shown that eccentric exercise is especially helpful for tendinosis. Eccentric exercise is when a muscle is forced to lengthen while it contracts because it is being used as a brake or to absorb energy while doing "negative work." On the other hand, concentric exercise is when a muscle shortens as it contracts because it is acting as an engine doing "positive work." Your quadriceps muscles perform eccentric exercise when you walk down a hill, ski, or decelerate when landing from a jump. Your quadriceps muscles perform concentric exercise when you ride a bike or swim. Given the same load, eccentric exercise places more stress on the muscles and tendons than concentric exercise. You might ask your physical therapist or sports medicine doctor about trying eccentric exercises as part of your strengthening program.
