About Tendinitis

A tendon is a flexible band of fibrous tissue that connects muscles to bones. Tendinitis is inflammation of a tendon. Tendons transmit the pull of the muscle to the bone to cause movement. They are found throughout the body, including the hands, wrists, elbows, shoulders, hips, knees, ankles, and feet. Tendons can be small, like those found in the hand, or large, like the Achilles tendon in the heel.

Bursitis is commonly caused by overuse or direct trauma to a joint. Bursitis may occur at the knee or elbow, from kneeling or leaning on the elbows longer than usual on a hard surface, for example. Tendinitis is most often the result of a repetitive injury or motion in the affected area. These conditions occur more often with age. Tendons become less flexible with age, and therefore, more prone to injury.

People such as carpenters, gardeners, musicians, and athletes who perform activities that require repetitive motions or place stress on joints are at higher risk for tendinitis and bursitis....Read more about Tendinitis NIH - National Institute of Arthritis and Musculoskeletal and Skin Diseases

Eccentric exercise protocols for chronic non-insertional Achilles tendinopathy: how much is enough?

Eccentric exercises for the calf muscles have been shown to be effective for chronic non-insertional Achilles tendinopathy (AT). However, the relative effectiveness of various dosages is unknown. A systematic review of randomized-controlled trials (RCTs) was designed to determine whether an optimum dose of eccentric exercises could be recommended. Three selected RCTs showed positive effects of very similar eccentric exercise protocols for chronic non-insertional AT. Owing to insufficient reported compliance data, a conclusion on the relative effectiveness of various compliances was not feasible. According to our review, the relative effectiveness of various dosages of eccentric exercises for AT is still unclear. However, it appears that highly variable compliance rates result in similar positive outcomes; these findings, therefore, highlight the need for further investigations.

Deep transverse friction massage for the treatment of lateral elbow or lateral knee tendinitis

We conducted an update of the review of the effects of deep transverse friction massage (DTFM) for people with lateral elbow or knee tendinitis. We found two studies (no new additional studies in this update) with 57 people.

Platelet‐rich therapies for musculoskeletal soft tissue injuries

Muscle, ligament and tendon injuries frequently occur during activities such as sports, and may be due to tissue degeneration. These injuries are more frequent in particular parts of the body, such as the tendons located in the shoulder, elbow, knee and ankle.

Terms to know

Achilles Tendinitis
The Achilles tendon connects the calf muscle to the back of the heel. Achilles tendinitis is a common injury that makes the tendon swell, stretch, or tear.
Bursitis
Inflammation or irritation of a bursa, the fibrous sac that acts as a cushion between moving structures of bones, muscles, tendons or skin.
Inflammation
Redness, swelling, pain, and/or a feeling of heat in an area of the body. This is a protective reaction to injury, disease, or irritation of the tissues.
Tendons
Tough, fibrous, cord-like tissue that connects muscle to bone or another structure, such as an eyeball. Tendons help the bone or structure to move.
