Design outcomes

Primary

Measure	Time frame
Overall feasibility score derived from the 15-item Likert questionnaire based on a 5-point Likert scale Feasibility is systematically assessed using a standardized 15-item Likert questionnaire. Evaluation is conducted •from a surgical-technical perspective by the Clinic of Orthopaedics and Sports Orthopaedics, TUM University Hospital Munich •microbiologically by the Institute of Microbiology, Immunology and Hygiene, TUM University Hospital Munich •pathologically/histologically by the Institute of Pathology, TUM University Hospital Munich.	—
