Outcomes After Superior Capsular Reconstruction With an Achilles Tendon-Bone Allograft Using the Modified Keyhole Technique: A 2-Year Follow-up of a Novel Technique for Irreparable Rotator Cuff Tears.

Background: Despite improved outcomes, failure or nonhealing of graft materials has been reported after superior capsular reconstruction (SCR) for massive irreparable rotator cuff tears.

Purpose: To evaluate the short-term clinical and radiological outcomes of a novel technique for SCR using an Achilles tendon-bone allograft.

Study Design: Case series; Level of evidence, 4.
