Abstract:

Objective

To analyze the effect of the quality improvement tool of the supply tube on the very early ambulating activity of the elderly after total knee arthroplasty.

Methods

A total of 122 elderly patients receiving RA-TKA from the Department of Orthopedics of the 920th Hospital of the Joint Logistics Support Force of PLA from March 2022 to April 2023 were conveniently sampled. Among them, 61 patients from March 2022 to September 2022 were not treated with the intervention of the supply circle quality improvement tool as the control group, and were given routine nursing and related health education.The observation group included 61 patients who used the tool intervention from October 2022 to April 2023.T test, Chi-square test and repeated analysis of variance were used to compare the rate of getting out of bed and the time of first ambulation time. Visual anaolgue scale (VAS) and Knee Society score (KSS) were performed at rest, during and after activity.

Results

The compliance rate of getting out of bed after surgery, the time of getting out of bed for the first time and the compliance rate of all types of getting out of bed were higher in the observation group than in the control group, with statistical significance (χ2=21.058, t=16.611, walking on ground≥10m χ2=8.396, bed to chair transfer χ2=11.517, standing at the bedside over five minutes χ2=9.210, all P<0.05). VAS score showed statistically significant differences in inter-group effect, intra-group effect and interaction effect(F=5041.267, 317.856, 10.749, all P<0.001).Simple effect analysis showed that VAS scores in the observation group were lower than those in the control group (F=10.680, 28.846, both P<0.05). KSS, KSS function scores,and range of motion of knee in observation group were significantly higher than those in control group (t=2.150,2.530, 14.489, all P<0.05).

Conclusion

The quality control circle quality improvement tool can improve the ultra-early ambulation rate of elderly patients after robot-assisted total knee arthroplasty, improve the active pain,shorten the first ambulation time after surgery, improve the joint range of motion, and promote the recovery of joint function.
