Fine structural alterations of collagen fibers in degenerative tendinopathy.
Fine structural alterations of collagen fibers were analyzed in 29 ruptured tendons. The most frequent alterations were longitudinal splitting, disintegration, angulation, and the so-called "Knickdeformation" of the collagen fibers. All these phenomena were considered to be the consequences of stress fatigue and mechanical injuries of fibers.
