Aim:
To determine the Minimal Clinically Important Difference (MCID) for Constant-Murley score (CMS), University of California Los Angeles (UCLA) shoulder score, and Oxford Shoulder Scores (OSS) after arthroscopic rotator cuff (RC) repairs.
Material And Methods:
306 patients were followed up for 24-month. MCID for CMS, UCLA and OSS were determined using simple linear regression according to patient satisfaction and expectation fulfilment.
Results:
The following MCID were identified:12-month: CMS 6.7, UCLA 3.0, OSS 3.3.24-month: CMS 6.3, UCLA 2.9, OSS 2.7.
Conclusions:
The various MCID could assist in meaningful interpretation of these scores and to power future comparative studies.
Level Of Evidence:
III.
