Rotator cuff disease is the most common pathology causing shoulder pain with an overall prevalence rate of 30%. There is a significant association between increasing age and the presence of rotator cuff tears. Spontaneous healing of clinically relevant tears has not been observed. Although satisfactory pain relief is possible without rotator cuff tendon healing, functional outcome is better for healed repairs. Operative treatment must be considered in the context of the reasonable expectations for success. Repairability and potential of surgically tendon construct to heal are important considerations in surgical indications. There is no difference of outcomes between the arthroscopic and the open techniques.
