FiberLocker® System Augmentation of Rotator Cuff Repairs

Purpose

The 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.

Augmentation of Rotator Cuff Repair using the FiberLocker® System 		All enrolled participants will undergo repair of the rotator cuff tear, with augmentation utilizing the FiberLocker® System.
  • Device: FiberLocker® System (encompassing FiberLocker® Instrument SN & SpeedPatch® PET)
    The FiberLocker® System is a mechanical augmentation system that includes an implant (SpeedPatch® PET) and an instrument (FiberLocker® Instrument SN) for its attachment. The implant is composed of non-woven PET fibers, and the instrument features a reciprocating needle at its tip, which pushes the individual patch fibers into the underlying tendon tissue.
