Ligaments consist of many strands of fibrous tissue which may run parallel or crisscross at various angles to each other. They provide stabilization of joints in all positions.
Pain occurs when normal tension on a ligament stretches the fibers.
In sprain or tearing, the fibers become separated from bone, and tthere is an accumulation of lymphy or blood at the site of injury. Healing occurs through initiation of the wound response cascade mediated by chemotactic agents and inflammatory cells. Fibrin is produced and develops into a permanent strong fibrous tissue attached to bone. The healing process can be interfered with. Subsequent activity can cause separation, or the repair capacity in the individual can be deficient.
