Tendinitis vs Tendinosis

Tendon injuries can result from activities that involve repetitive motion, resulting in micro-tears within the collagen fibers of the tendon. Tendinitis and tendinosis are different types of tendon injury, which may require different treatment approaches.

Tendinitis is associated with inflammation of the tendon, which can resolve itself with rest, bracing, corticosteroid injections, and physical therapy. When a tendon is unable to heal, or is repeatedly reinjured, the tendon structure can breakdown causing degeneration of the tendon fibers.  This condition is referred to as tendinosis and is best treated by resection of diseased tissue, thus allowing the tendon to regain its structure and strength through physical therapy and home exercises.

Healthy Tendon

Strong, flexible bands of tissue that connect muscle to bone and transmit the energy needed to create movement.

Tendinitis

Refers to an inflamed tendon without microscopic damage.

Tendinosis

Refers to a chronically damaged tendon with disorganized fibers and tissue degeneration.

What is TenJet?

TenJet is a needle-like device, designed to treat tendinosis by using pressurized saline to selectively resect and remove diseased tendon tissue while sparing healthy tissue.

The device enables sports medicine physicians to treat patients suffering from chronic tendon pain due to tennis or golfers elbow, jumpers knee, Achilles tendinitis, or calcifications in the shoulder, elbow, hamstring or hip. It can also be used to treat plantar fasciitis.

The minimally invasive intervention is performed in an outpatient setting, aiming to accomplish goals of traditional surgery using real-time ultrasound imaging to visualize the diseased tissue, and requiring only a small incision.
