Objective:To explore the effect of stability training combined with pain management in the nursing process of patients undergoing hip replacement surgery on joint function recovery and sleep quality improvement.Methods:A total of 88 patients who underwent hip replacement surgery in our hospital from May 2022 to October 2023 were selected as the subjects.They were ran-domly divided into a control group(44 cases,receiving routine nursing support during postoperative recovery)and an observation group(44 cases,receiving stability training combined with pain care)using an Excel table for grouping.Compare the pain level,joint function scores,and sleep quality between two groups of children.Results:Showed that the observation group had lower post-operative VAS levels,initial weight-bearing activity time,and stasis resolution time compared to the control group(P<0.05).Af-ter intervention,the observation group was higher than the control group(P<0.05).After intervention,the PSQI score of the ob-servation group was lower than that of the control group(P<0.05).The incidence of postoperative complications in the observa-tion group was lower than that in the control group(P<0.05).Conclusion:Implementing stability training combined with pain care in the postoperative care process of patients undergoing hip replacement surgery can reduce the degree of postoperative pain,help patients recover joint function,improve sleep quality,reduce the incidence of complications.
