The enthesis (plural: entheses) is the connective tissue between tendon or ligament and bone.There are two types of entheses: Fibrous entheses and fibrocartilaginous entheses.In a fibrous enthesis the collagenous tendon or ligament directly attaches to the bone whereas the fibrocartilaginous interface encompasses four transition zones: Tendinous area displaying longitudinally oriented fibroblasts and a parallel arrangement of collagen fibres Fibrocartilaginous region of variable thickness where the structure of the cells changes to chondrocytes Abrupt transition from cartilaginous to calcified fibrocartilage—the so-called ‘tidemark’ or ‘blue line’ Bone↑
