RecruitingDevice studyFiberLocker® System Augmentation of Rotator Cuff RepairsThe purpose of this study is to prospectively evaluate healing, functional clinical outcomes, and safety of arthroscopic rotator cuff repairs augmented with the FiberLocker® System (encompassing the SpeedPatch® PET and the FiberLocker® Instrument SN). The primary outcome measure is healing evaluation based on Magnetic Resonance Imaging (MRI) at a minimum of 6 months post-operatively. The secondary outcome measures are the Sugaya classification, Goutallier Stage and tendon quality based on MRI as well as objective scores and patient-reported outcome measures (PROMs) from validated outcome scoring systems.
