Degenerative lesions of the shoulder occur very frequently and their incidence increases with age. The Constant-Murley score is currently considered the gold standard in Europe to assess the shoulder and is widely used by the orthopaedic community to follow up on shoulder pathologies. However, healthcare professionals are taking an increasing interest in self-administered patient-reported out-come measures. Several self-administered questionnaires are available to assess the shoulder. Among these questionnaires, the OSS (Oxford Shoulder Score) is considered to be quick, simple, and reliable for the English-speaking population. This score was initially developed at the University of Oxford in 1996. It is a self-administered questionnaire designed to evaluate pain and shoulder function through 12 questions. This score has since been adapted in different languages but not in French.

The aim was to develop a translation and a transcultural adaptation of the OSS and to assess its validity in native French-speaker patients with shoulder pain.
