About

The goal of this clinical trial is to compare the effectiveness of combined care guidance and general care guidance on pain scores, anxiety levels and joint mobility in patients undergoing total artificial knee replacement. The main questions it aims to answer are:

• Does combined care coaching reduce patient pain scores and anxiety levels after surgery?
• Does combined care guidance improve knee joint mobility after surgery? Researchers will compare combined care guidance and general care to see if combined care guidance reduces patients' pain scores and anxiety levels after surgery, and improves knee joint mobility after surgery.

Participants will:

• Watch pain and rehabilitation exercise guidance videos before surgery and learn how to use a walker.
• Complete questionnaires before surgery, 24 hours, 48 hours, 72 hours and three months after surgery.
• Questionnaire records pain level, anxiety level and joint mobility.

Full description

Background:The population is aging rapidly, and an aging society is approaching. According to Taiwan government statistics, the population over 65 years old has reached 16.2%. The number of people suffering from knee osteoarthritis has reached 860,000, and the number of patients undergoing total artificial knee replacement has reached 29,000. people.Artificial knee replacement can effectively relieve joint pain, correct joint deformities, and improve joint function. However, patients who undergo total artificial knee replacement still experience moderate to severe pain after surgery. Effective pain control can promote early rehabilitation and early ambulation of patients. In clinical practice, it is more common to provide a single interventional measure to improve the pain level after surgery, but less to provide combined measures before surgery, which leads to the motivation for discussion.

Purpose:To compare the effectiveness of combined care guidance and general care Method:guidance on pain scores, anxiety levels and joint mobility of patients undergoing total artificial knee replacement before surgery, 24 hours, 48 hours, 72 hours and three months after surgery.Experimental group: Researchers provided combined care, watched animated videos, demonstrated rehabilitation exercises and practiced walking using walkers.Control group: The researchers provided general preoperative care and demonstrated rehabilitation exercises and the use of walking aids after surgery.

:This study adopted an experimental research design, single-blind, and randomly assigned groups, one experimental group and one control group.Data were collected five times in total, before surgery, 24 hours after surgery, 48 hours after surgery, 72 hours after surgery and 3 months after surgery.All five data collections are required to fill in the Numerical Rating Scale (NRS) state-trait anxiety inventory (STAI), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC)
