To explore the effect of outcome oriented multi-dimensional intervention in the rehabilitation period of elderly patients with osteonecrosis of the femoral head (ONFH) after hip replacement.

Eighty-six patients with ONFH who were diagnosed with advanced necrosis of the femoral head through imaging at Beijing Friendship Hospital affiliated with Capital Medical University from November 2020 to November 2021 and underwent unilateral total hip replacement surgery for the first time were selected. The patients with other hip disease, dysfunction of limbs, mental diseases, tumors and insufficiency of vital organs were excluded. According to the random number method, the enrolled patients were divided into the control group and the observation group, 43 cases in each group. The control group received routine intervention, while the observation group received outcome oriented multidimensional intervention. The visual analog scale (VAS) for pain, Harris hip function scale (Harris), Hamilton depression scale (HAMD), and Hamilton anxiety scale (HAMA) before and after intervention between two groups were analyzed, as well as the first time of getting out of bed, length of hospital stay, and incidence of postoperative complications. Independent sample t test was used for inter group comparison of quantitative data, and paired sample t test was used for intra group comparison. The counting data analysis adopted chi square test.

Compared with the data before intervention, VAS score, HAMD and HAMA scores of both groups decreased after intervention (t=3.963, 3.624, 4.325, 3.698, 4.524, 3.597, all P<0.05); and the data of observation group were lower than the control group (t=3.246, 3.562, 4.304, all P<0.05). Compared with before intervention, the Harris scores of both groups increased after intervention (t=16.542, 13.624, both P<0.05); and the data of observation group was higher than the control group (t=5.642, P<0.05). The first time of getting out of bed and hospitalization time in the observation group were shorter than those in the control group (t=3.032, 3.674, both P<0.05), and the total incidence of postoperative complications was lower than that in the control group (χ²=5.108, P<0.05).

Outcome oriented multidimensional interventions can alleviate the pain level, anxiety, and depression of elderly ONFH hip replacement patients, improve hip joint function, reduce the incidence of postoperative complications, and accelerate postoperative recovery.
