Prospective Sensor Controlled Compliance Analysis of Shoulder Abduction Splint After Rotator Cuff Repair

The postoperative shoulder rehabilitation in an abduction brace after rotator cuff reconstruction of the shoulder is crucial for a successful healing of the reconstruction. In this study the investigators want to analyse the abduction brace-wearing time using a electronic sensor, which is implanted in the abduction brace. The participants will be informed about the sensor after completion of the abduction brace rehabilitation 6 weeks postoperatively.
