详细说明
This single-centre pragmatic randomized pilot trial will evaluate the feasibility and preliminary effectiveness of a web-based conversational postoperative assistant following primary total knee arthroplasty (TKA). Participants will be randomized in a 1:1 ratio to receive either standard postoperative care alone or standard care plus access to the conversational assistant for 6 weeks after surgery.
The assistant provides evidence-based postoperative education, recovery guidance, answers to common patient questions, and safety-oriented recommendations. The primary outcome is overall patient satisfaction at 6 weeks. Secondary outcomes include pain intensity, exercise adherence, unplanned healthcare contacts, and postoperative complications. The study is designed to generate preliminary evidence to support the development of a larger definitive randomized controlled trial.

实验性的:Intervention
Participants receive standard postoperative care plus access to a web-based conversational postoperative assistant for 6 weeks after primary total knee arthroplasty.
|
Participants assigned to the intervention group receive access to a web-based conversational assistant for 6 weeks after primary total knee arthroplasty.
The assistant provides evidence-based postoperative education, recovery guidance, answers to common patient questions, and safety-oriented recommendations.
It is available on demand and complements, but does not replace, standard postoperative care.

无干预:Control
Participants receive standard postoperative care without access to the web-based conversational postoperative assistant.
