Use of Nanoscaffold Augmentation in Rotator Cuff Repair: Clinical Outcome and Ultrasound Assessment of Healing Rates and Vascularity

Inclusion Criteria: * -symptomatic supraspinatus or supraspinatus and infraspinatus tear that can be repaired to the greater tuberosity in an anatomical manner using a dual layer repair technique. * also included will be patients that have concomitant pathology addressed at time of surgery, specifically pathologies of the biceps tendon (tenodesis or tenotomy), arthrosis of the acromioclavicular joint (distal clavicle resection), or labral tearing (debridement or repair) * included age range of subjects will be from 18-80 years old Exclusion Criteria: * diabetes, cancer or medical states that may impair healing, such as organ transplantation or systemic inflammatory process treated with immune modulating drugs (chemotherapy, immunosuppression drugs) * prior surgery to the ipsilateral rotator cuff tendon * need of soft tissue releases to accomplish an anatomic repair, partial repairs and/or concomitant subscapularis repair * significant glenohumeral arthritis * active or ongoing infection * pregnancy
