Tendons are comprised of long strong strands of protein called collagen, intersapced with cells called tenocytes.
Tendons transmit amazingly huge repetitive forces, undertaking activities such as running or jumping. Some time their intrinsic healing ability is overwhelmed, leading to tendon micro-tears. These degenerative lesion as called a tendinopathy. Tendons have a poor blood supply and their healing rate is much slower than other musculoskeletal tissues.
Sometimes an abnormal healing response to the micro-tears occurs, known as angiofibroblastic dengeneration.
Patients notice pain, swelling and impaired function at the site of the tendon injury.
Common tendon injuries include Jumper's Knee, Tennis Elbow, Golfer's Elbow, Achilles Tendinosis, Hamstring Tendinosis, Hip adductors and Gluteal Tendinosis and Plantar fascitis. De Quervain's tenosynovitis is also similar.
