Evidence of Healing of Partial-thickness Rotator Cuff Tears Following Arthroscopic Augmentation With a Collagen Implant: A 2-year MRI Follow-up

Abstract

SummaryBackground: partial-thickness rotator cuff tears frequently enlarge due to increased local strain and often progress to full-thickness tears. Studies suggest the addition of new tendinous tissue to injured cuff tendons would significantly decrease peak strain, possibly protecting against tear progression. The aim of this study was to assess the ability of a highly-porous collagen implant to induce new tissue formation and limit tear progression when placed on the bursal surface of partialthickness cuff tears.
