摘要
目的 分析髋关节置换术后患者采取知信行理论的干预模式对其预防髋关节置换术后假体脱位
的价值。方法 应用随机数字表法对于本院 2021 年 2 月-2022 年 2 月期间收治的 78 例髋关节置换术患者进
行分组。其中一组为参考组（n=39），本组采取常规干预方法；另外一组为实验组（n=39），本组采取 知信
行理论干预。以假体脱位发生率、髋关节功能评分以及 ADL 评分评价两组患者干预后的效果。结果 实验
组假体脱位发生率明显要比参考组低（P＜0.05）。实验组术后 1 个月、3 个月以及 6 个月 Harris 评分明显要
比参考组高（P＜0.05）。实验组术后 1 个月、3 个月以及 6 个月 ADL 评分明显要比参考组高（P＜0.05）。
结论 在髋关节置换术后患者采取知信行理论的干预模式，能够显著减少假体脱位发生率，改善患者的髋关
节功能，提升其生活能力。此种方法值得在临床上推广应用。

Abstract
Objective To analyze the value of the intervention mode of knowledge, belief and practice theory
in preventing the dislocation of prostheses after hip replacement. Methods 78 patients with hip replacement in our
hospital from February 2021 to February 2022 were divided into groups by random number table. One group was
the reference group (n=39), and the routine intervention method was adopted in this group; The other group was the
experimental group (n=39), which was intervened by the theory of knowledge, belief and practice. The incidence of
prosthesis dislocation, hip function score and ADL score were used to evaluate the effect of intervention in the two
groups. Results The incidence of prosthesis dislocation in the experimental group was significantly lower than that
in the reference group (P<0.05). The Harris score of the experimental group was significantly higher than that of
the reference group 1 month, 3 months and 6 months after operation (P<0.05). The ADL score of the experimental
group was significantly higher than that of the reference group 1 month, 3 months and 6 months after operation
(P<0.05). Conclusion The intervention mode of knowledge, belief and practice theory can significantly reduce the
incidence of prosthesis dislocation, improve the hip joint function of patients and enhance their living ability after
hip replacement. This method is worth popularizing and applying in clinic.
Key words： Knowledge, trust and practice theory; Hip replacement; Prosthesis dislocation; Hip jointfunction; Living ability
