Why the study?
Does the use of 2.8 mm anchors compared to 4.5 mm anchors reduce the volume of bone replaced in patients undergoing double-row rotator cuff repair?
Does the use of 2.8 mm anchors compared to 4.5 mm anchors reduce the volume of bone replaced in patients undergoing double-row rotator cuff repair?
Using 2.8 mm anchors in double-row rotator cuff repair significantly reduces the volume of bone replaced compared to 4.5 mm anchors, preserving bone stock for potential revisions without compromising clinical outcomes.
May support smaller anchors to minimize bone loss in rotator cuff repair; leaves open whether outcomes match larger anchors.
Rotator cuff tears are a common shoulder problem and recently double-row repair techniques have shown superior biomechanical advantages when compared to single-row constructs in a properly selected patient. This study compared 2.8 mm and 4.5 mm anchors with respect to clinical and radiological outcome in two groups of patients. Of course, for the same number of 4.5 anchors used. Volume of Bone Replaced (VBR) will be far less if 2.8 anchors are used in equal number. But, in such surgeries, the ultimate objective was to restore the anatomic footprint and the number of anchors used varied accordingly.
