With the app, patients are able to self-monitor their daily protein intake and PA level, have insight in personal goals on protein intake and receive (real-time) feedback. The patients receive an ankle-worn PA monitor (PAM) and corresponding application one week prior to surgery to get familiarized with the application. After discharge, the patients continue the use for 3 months and patients will be monitored and coached by a physiotherapist and dietician during this period. The intervention will be tailored on the patients personal needs and preferences based on a shared decision making process with the patient. The patients will be coached by the physiotherapist and dietician following the principles of Motivational Interviewing. Primary outcome(s): The main study endpoint is postoperative recovery in physical functioning measured with the CAT PROMIS-physical functioning item bank. The most important secondary outcome is objectively measured level of physical activity (average stepping minutes per day).
