Inclusion criteria

Inclusion criteria: All men and women aged 18 to 65 who are diagnosed with a type 5 Rockwood AC joint dislocation during the study period will be included in the study. Sufficient compliance to participate in this study as well as the existence of the signed study consent form after oral and written explanation is a prerequisite.

Exclusion criteria

Exclusion criteria: Exclusion criteria are pre-existing diseases that affect mobility or strength in the affected shoulder joint, previous operations on the affected shoulder, the implementation of immunosuppressive therapy, a lack of patient consent, insufficient compliance, or legal incompetence. A change from one group to another due to the patient's will does not result in exclusion from the study. The same applies if the patients do not agree to the randomization. The patients will still be clinically monitored and listed as a separate group in the study design (the "drop-out" group).

Design outcomes

Primary

Measure	Time frame
ACJI-Score (Acromioclavicular Joint Instability Score) Timetable: Measured at fixed intervals: (2 weeks (conservative group only), 6 weeks, 6 months, and 12 months post-surgery/trauma)	—

Secondary

Measure	Time frame
Clinical Endpoints: • Range of Motion (ROM) of the shoulder joint • Patient satisfaction (scale from 0 to 10 (0 = very dissatisfied, 10 = maximum satisfaction)), • Pain level (scale from 0 to 10 (0 = no pain, 10 = worst pain)) • Need for analgesics • Return-to-sports • Return-to-work Objective Scores: • Constant Score • Taft Score • ASES Score (American Shoulder and Elbow Surgeons score) • SACS (Specific AC Score) • SSV (Subjective Shoulder Value) • SICK Scapula Score (Scapular Dyskinesia) Radiological Difference: • Difference between the affected side in AC + CC distance compared to the opposite side in % (X-ray/Sonography) Timetable: Measured at fixed intervals: (2 weeks (conservative group only), 6 weeks, 6 months, and 12 months post-surgery/trauma)	—
