Conditions

Rotator Cuff Tear

Brief summary

Retear rates after arthroscopic rotator cuff repairs remain unsatisfactorily high. Recently, attention has been paid to restore the rotator cuff's native anatomy by reconstructing the superior joint capsule. However, the debate whether to reconstruct only the superficial tendinous part or also the deeper capsulo-ligamentous part of the rotator cuff is ongoing. Thus, the intention of the present study is to compare double-layer versus single-layer arthroscopic rotator cuff repair regarding retear rate and clinical outcome.

Design outcomes

Primary

MeasureTime frameDescription
Retear rate12 months postoperativelyComparison of re-ruptures rate evaluated with magnetic resonance imaging between groups

Secondary

MeasureTime frameDescription
Range of motion (ROM)baseline, 24 and 60 months postoperativelyComparison of ROMs between groups
Satisfaction with the procedure24 and 60 months postoperativelyComparison of satisfaction with the procedure between groups. Satisfaction is evaluated by asking patients one question to rate their satisfaction with the procedure based on a likert scale (4 = 'very satisfied', 3 = 'quite satisfied', 2 = 'moderately satisfied', 1 = 'less satisfied', 0 = 'not at all satisfied').
VASbaseline, 24 and 60 months postoperativelyComparison of the Visual Analogue Scale (VAS) between groups
SSTbaseline and 24 months postoperativelyComparison of the Simple Shoulder Test (SST) between groups
ASESbaseline, 24 and 60 months postoperativelyComparison of the American Shoulder and Elbow Surgeons score (ASES) between groups. The ASES is a patient-rated questionnaire with a total between 0 and 100 points with higher scores indicating better outcome.
Constant-Murley scorebaseline, 24 and 60 months postoperativelyComparison of the total Constant-Murley score (min 0 to max 100; higher values represent a better outcome) between groups
WORCbaseline and 24 months postoperativelyComparison of the Western Ontario Rotator Cuff Index (WORC) between groups
SSVbaseline, 24 and 60 months postoperativelyComparison of the Simple Soulder Value (SSV) between groups
SF-36baseline, 24 and 60 months postoperativelyComparison of the quality-of-life score short form 36 (SF-36) between groups
Tendon integritybaseline and 60 months postoperativelyComparison of tendon integrity (re-tear / no re-tear) evaluated with magnetic resonance imaging between groups
qDASHbaseline, 24 and 60 months postoperativelyComparison of the quick Disability of the Arm, Shoulder and Hand (qDASH) between groups
