Orthopedic surgery of the limbs presents a unpredictable postoperative course, which can be more or less lengthy in terms of functional recovery and resumption of personal or professional activities. Not uncommon, convalescence can require many months with dramatic personal and/or socio-professional consequences (disability, unemployment, etc.), particularly in the postoperative development of complex regional pain syndrome (CRPS) and/or adhesive capsulitis.

Among the suspected contributing factors, the existence of an unfavorable preoperative psychological context in patients is often mentioned.

This research is based on the hypothesis that a high level of preoperative stress in patients could contribute to the occurrence of more significant postoperative complications in patients who have undergone shoulder surgery.

The main objective is to measure the level of preoperative stress in patients undergoing surgery for rotator cuff tendinopathy.

Inclusion Criteria:

• Patient, male or female, over 18 years of age
• First-line surgery for rotator cuff tendinopathy (torn and untorn)
• Subject affiliated with or covered by a social security scheme
• Collection of the patient's non-opposition to participate in the study

Exclusion Criteria:

• Patients with medical history of adhesive capsulitis or complex regional pain syndrome (CRPS)
• Patients with a history of diabetes or thyroid dysfunction
• Patients with a history of fibromyalgia
• Patients with a history of mental illness (PMD, schizophrenia)
• Patients taking antidepressants or similar medications
• Patients participating in another clinical trial
• Protected patients: adults under guardianship, curatorship, or other legal protection, deprived of liberty by judicial or administrative decision;
• Pregnant, breastfeeding, or parturient women;
• Patients hospitalized without their consent.

Patients will be recruited from the orthopedic surgery department of the centers (Clinique de l'Union, Clinique la Croix du sud and Clinique des Cèdres).
