Abstract 【Objective】To explore the related factors affecting postoperative pain in patients undergoing primary total hip arthroplasty. 【Methods】The clinical data of 114 patients who underwent total hip arthroplasty from March 2016 to April 2019 were analyzed retrospectively. The patients were followed up for 2 weeks. According to the postoperative pain visual analog score (VAS), the patients were divided into moderate and severe pain group (VAS ≥ 4, observation group) and mild pain group (VAS ≤ 3, control group). The related factors that may affect postoperative pain were observed, and univariate analysis and binary logistic regression analysis were carried out. 【Results】 The postoperative follow-up showed that 23 of 114 patients had hip pain within 2 weeks after operation, and the incidence was 20.18%; The age, postoperative leukocyte (WBC), C-reactive protein (CRP) and VAS scores of the observation group were higher than those of the control group; The postoperative functional exercise time was shorter than that in the control group (P<0.05); The incidence of pain increased with the increase of anxiety (P<0.05); Multivariate logistic regression analysis showed that short postoperative functional exercise time, large length difference of both lower limbs, and increase of WBC and CRP were independent risk factors for pain after hip arthroplasty (OR=3.08, 3.52, 3.90, 3.89;P<0.05). 【Conclusion】The postoperative pain of patients undergoing total hip arthroplasty is affected by many factors. Short postoperative exercise time, large difference in the length of both lower limbs, and elevated levels of WBC and CRP were independent risk factors for pain after hip arthroplasty. Clinically, we should formulate reasonable operation methods according to the differences of patients, and avoid the occurrence of risk factors as far as possible.
