PurposePatient-reported outcome measures (PROMS) are increasingly used for patient evaluation, as well as for scientific research. Few are used for practical purposes in the clinical setting, and few are reliable enough to allow proper feedback to physicians. Two of the most commonly used assessment tools in shoulder instability are the Walch–Duplay and the Rowe scores. The aim of this study was to evaluate the validity of self-administered versions of the Walch–Duplay and Rowe scores following shoulder stabilization procedure.MethodsBetween the months of May and December 2021, all patients who were followed in one of six institutions for shoulder instability were included. Patients were required to anonymously fill a self-administered version of Walch–Duplay and Rowe score. The classic scores were measured by the surgeon. Correlations between self-assessment and physician-assessment were then recorded.ResultsA total of 106 patients were evaluated during the study period. Using the Spearman coefficient for correlation, a strong correlation (r> 0.5) was found between the results of the self-administered questionnaire and the surgeon-measured score. The difference between surgeon- and patient-administered questionnaires was non-significant.ConclusionThe self-administered version of the Walch–Duplay and Rowe questionnaires can reliably be used in the clinical setting for post-operative follow-up of patients undergoing shoulder stabilization procedures.Level of evidenceLevel II.
