Rotator cuff tear may have significance include os acromiale and acromial spurs. Environmental factors implicated include increasing age, shoulder overuse, smoking, and any medical condition that affects circulation or impairs the inflammatory and healing response, such as diabetes mellitus. Intrinsic factors refer to injury mechanisms that occur within the rotator cuff itself. The principal is a degenerative-microtrauma model, which supposes that age-related tendon damage compounded by chronic microtrauma results in partial tendon tears that then develop into full rotator cuff tears. As a result of repetitive microtrauma in the setting of a degenerative rotator cuff tendon, inflammatory mediators alter the local environment, and
Rotator cuff tear which they use grafted tissues rather than stitching to reconnect tendon segments. This can result in a complete repair. Other options are a partial repair, and reconstruction involving a bridge of biologic or synthetic substances. Partial repairs typically are performed on patients with retracted cuff tears. Two methods of promoting rotator cuff healing are injecting patients' own stem cells (or other growth factors) into the site of the repair, and installing scaffolds (natural or artificial supports that maintain tissue contour). The results of using PRP (platelet rich plasma) to augment the healing of rotator cuff repair at the time of
