Following hospital discharge, patients must manage pain, wound care and home rehabilitation with limited professional support. This pragmatic randomised pilot trial will evaluate whether a web-based conversational postoperative assistant, used in addition to standard care, improves patient satisfaction and exercise adherence during the first 6 weeks after TKA. Forty to sixty patients undergoing primary elective TKA will be randomised 1:1 to standard care with or without access to the conversational assistant. The primary outcome is overall patient satisfaction at 6 weeks. Secondary outcomes include pain intensity, exercise adherence, unplanned healthcare contacts and postoperative complications.",[27],"Osteoarthritis (OA) of the Knee",[29,30,31,32,33],"Total Knee Arthroplasty","Conversational assistant","Patient Satisfaction","Artificial Intelligence","Digital Health","NOT_YET_RECRUITING","2026-07-23",{"date":37,"type":38},"2026-07-28","ACTUAL",{"date":40,"type":21},"2026-10",{"date":42,"type":21},"2027-03",{"name":44,"class":45},"Wojciech Sroga","OTHER",""]
