Effect of Different Cold Therapy Programs in Patients Received Total Knee Arthroplasty Operation

Condition(s) studied

Investigational drug(s) / intervention(s)

mixed ice and water, continuous ice application: the ice pack was placed on the knee joint immediately after returning to the ward for 24 hours, and the ice pack was replaced every 3 to 4 hours, if it melted, replaced immediately.

mixed ice and water, intermittent ice compress: within 72 hours after operation, the patients were given ice compress for 20 minutes each time, with an interval of 2 hours, 3 times a day

full ice, continuous ice compress: After returning to the ward, an ice pack should be placed on the knee for 24 hours. The ice pack should be replaced every 3-4 hours and replaced immediately if melted

full ice, intermittent ice compress: Within 72h after surgery, the patient applied ice for 20min each time, with an interval of 2h,3 times a day.

Study summary

This study conducts clinical experiments on the form, temperature, frequency and other issues of cooling therapy, so as to provide scientific evidence for the practice of cooling therapy and improve the comfort and effect of cooling therapy, so as to achieve the goal of improving service and patient experience proposed by the National Health Commission.

Eligibility

Primary outcome measure(s)

• numerical rating scale ，NRS — Day 1, Day2, Day 3
  ostoperative pain intensity will be evaluated using the Numerical Rating Scale (NRS) at 24 hours following total knee arthroplasty (TKA). The NRS is an 11-point scale ranging from 0 to 10, where 0 represents "no pain" and 10 indicates "the worst imaginable pain." Patients will self-report their pain level by selecting a numerical value corresponding to their perceived intensity. The scale is visually presented as a 10-cm horizontal line divided into 10 equal segments, with each segment labeled sequentially from 0 to 10.
• general comfort questionnaire，GCQ — Day 1, Day2, Day 3
  GCQ was developed by the famous nursing scientist Kekaba. In 2004, it was sinicized by Chinese scholar Julixia et al. It is suitable for all kinds of people with discomfort. The scale contains four dimensions of physiology, psychology, environment and social culture, a total of 28 items, using 1-4 Likert scores, with 1 indicating "strongly disagree" and 4 indicating "strongly agree". The total scores range from 28 to 112. That is, patients were in low comfort (total score \< 60), moderate comfort (60-90 points) and high comfort (\> 90 points). Clinical research found that the scale had good reliability and validity (Cronbach's α coefficient was 0.893).
• Joint range of motion (ROM), knee swelling — Day 1, Day2, Day 3
  Range of Motion (ROM) Range of Motion (ROM), also termed joint range of motion, refers to the maximum arc of movement achievable by a joint during motion. ROM is categorized into two types based on the force driving the movement:
