Document Summary
Inert tissue: resist force, contractile tissue, muscle, ability to generate and resist force. Joints move so there has to be flexibility in the ligaments: tendon is to attach muscle to bone, contracting muscles tendons help to move bones, have high collagen fibers. Stretch, tear or rip to the muscle or adjacent tissue: can be mild tear or complete muscle rupture. Involves large force producing muscle: contractile is usually strained. Tendon injuries: collagen tends to weaken, re-absorption occurs with repeated microtrauma, results in weakening tendons, also occurs with immobilization, weakens the tissue, requires gradual loading and conditioning. Tendinitis: tendon inflammation, gradual onset with microtrauma. Swelling and pain: crepitus, sticking of tendon due to accumulation of inflammatory by-products on irritated tissue, rest and modify activity. Less inflammation and more visibly swollen with stiffness and restricted motion: tender lump. Inflammation of synovial sheath: acute case - rapid onset, crepitus and diffuse swelling, chronic cases- thickening of tendon with pain and crepitus.
