To observe the implementation effect of an intelligent training system in the perioperative rehabilitation of patients undergoing total knee arthroplasty (TKA).

A prospective randomized controlled trial was conducted. A total of 40 patients who underwent TKA in the Department of Orthopedics, Beijing Hospital, from December 2023 to July 2024, The cohort consisted of 13 males and 27 females, with a mean age of 70.40±6.22 years. Using a random number table, patients were allocated to either the control or experimental group, with each group consisting of 20 patients. The control group received standard rehabilitation training, while the experimental group received rehabilitation training based on an intelligent training system in addition to conventional rehabilitation. Outcomes compared between the two groups included knee joint function, range of motion (ROM), adherence to rehabilitation training, first ambulation time, activities of daily living (ADL), nursing satisfaction,and pain levels.

Repeated measures analysis of variance for HSS scores, ROM, Barthel Index, and NRS pain scores at various postoperative time points indicated statistically significant differences between the groups (P<0.001). Compared with the control group, the experimental group showed higher knee function scores at 4 days and 6 weeks postoperatively (P<0.001), greater knee range of motion at postoperative days 1, 4, and 6 weeks (P<0.001), higher activities of daily living scores at postoperative days 4 and 6 weeks (P<0.001), and lower pain scores from postoperative days 1 to 4, as well as at 6 weeks (P<0.05). Significant interactions between group and time point were observed (P<0.001), with statistically significant differences noted across all postoperative time points in the experimental group. Furthermore, the experimental group showed significantly superior exercise compliance, time to first ambulation, and nursing satisfaction compared with the control group (P<0.001).

The intelligent wearable training system demonstrates significant efficacy in perioperative rehabilitation for TKA patients, effectively improving rehabilitation outcomes and warranting widespread clinical application and promotion.
