Threshold scores for treatment success after arthroscopic bankart repair using Oxford Shoulder Instability Score, Constant-Murley Score, and UCLA shoulder score

AIM: To determine the threshold score for Oxford Shoulder Instability Score (OSIS), Constant-Murley score (CMS), and University of California Los Angeles (UCLA) shoulder score that predict treatment success after arthroscopic bankart repairs. METHODS: 77 patients were followed up for 12-mmonth. Threshold scores were determined by Receiver Operating Characteristic (ROC) analyses with treatment success defined as improvement in pain, no re-dislocation, expectation and satisfaction met. RESULTS: The follow threshold scores were identified:6-month: OSIS 35, CMS 68,UCLA 2612-month: OSIS 24, CMS 84, UCLA 33. CONCLUSION: OSIS, CMS, and UCLA are good predictors of treatment success after arthroscopic bankart repair.Level of EvidenceIII.
