ABSTRACT
PURPOSE: To program a Web application for simplified calculation of the Advanced Rotator Cuff tear Score (ARoCuS), which is a 5-part, 18-item treatment-oriented intraoperative scoring system for intraoperative evaluation of rotator cuff tears. METHODS: ARoCuS characteristics (torn tendon, tear size, tissue quality and tear pattern) were assessed intraoperatively on 40 consecutive patients with rotator cuff tears for calculation of defect category ΔV. Video recordings were used to re-calculate the ARoCuS after surgery and to assess inter-observer reliability. RESULTS: The Web application "ARoCuS App" was built using Angular and transformed to a native iOS application. The intraoperative use of the app proved to be simple and intuitive. There were inter-/intra-observer differences neither in ARoCuS defect categories ΔV nor in ARoCuS characteristics (p > 0.05). CONCLUSION: The ARoCuS app is a supportive tool for integration of standardized treatment procedures and documentation of rotator cuff tears in clinical routine.
