Tendon tears or breaks are difficult to repair both physiologically and surgically. Why?
What will be an ideal response?
Tendons are composed of dense regular connective tissue, which consists of densely packed, parallel connective tissue fibers. This type of tissue has relatively few cells and vascular supply is poor; consequently, repair is slow. Because of the structure of the tissue, surgical repair can be compared to attempting to suture two bristle brushes together.
