Abstract
BackgroundAs the total hip arthroplasty (THA) mainly aims to improve the quality of life of the patients, study of health-related quality of life (HRQoL) after THA has attracted much attention. Yet, the results considerably vary between studies. Here, we evaluate the HRQoL of the patient after THA, for the first time in the Iranian population.MethodsIn a case-control study, HRQoL was assessed in 217 patients after THA and compared with a matched reference population. The 36-item short-form health survey (SF-36) was used for the evaluation of HRQoL. A multiple linear regression model was used to investigate the influence of sociodemographic and clinical characteristics of the patients on the HRQOL.ResultsThe mean follow-up of the patients was 27 ± 18 months. The mean total SF-36 score was 41.4 ± 22.2 in the case and 67.3 ± 26.6 in the control group (p = 0.001). The mean physical component score, but not the mental component score, was significantly lower in the patient group (p = 0.001). Except for the vitality and emotional role, all other SF-36 subscales were significantly lower in the case group. Male sex (B = 4.52, p = 0.023), number of comorbidities (B = − 4.82, p = 0.011), body mass index (B = − 1.18, p = 0.044), number of post-operative complications (B = − 6.57, p = 0.001), and adherence to physiotherapy protocol (B = 2.09, p = 0.014) were associated with HRQoL after THA.ConclusionAlthough THA is considered as one of the most successful orthopedic practices, it is associated with remarkable reduced HRQoL in Iranian population when compared with the reference population. A variety of patients-associated factors influence the HRQoL after THA.
Highlights
As the total hip arthroplasty (THA) mainly aims to improve the quality of life of the patients, study of health-related quality of life (HRQoL) after THA has attracted much attention
According to our multivariate analysis, male gender, lower body mass index (BMI), lower number of comorbidities and post-operative complications, and adherence to the physiotherapy protocol were positively associated with the total 36-tem short-form Health Survey_ (SF-36) score
It is of note that the majority of the studies included in the review of Shan et al were performed in the developed countries, while here we reported the HRQoL of the patient in a developing country
Summary
As the total hip arthroplasty (THA) mainly aims to improve the quality of life of the patients, study of health-related quality of life (HRQoL) after THA has attracted much attention. While conventionally clinical parameters have been used to assess the outcomes of patients after THA, a recent consensus states the patientreported Health-related quality of life (HRQoL) is a better indicator of patients’ outcome and should be primarily used in due researches and clinical setting as well [8]. The results of the HRQoL assessment after THA vary considerably between studies [9]. In addition to the patient-related factors such as age, gender, comorbidity, and preoperative functional status that have been associated with the results of HRQoL, the role of other factors such as individual orthopedic surgeon have been noticed [10]. A thorough evaluation of HRQoL of patients after THA is still encouraged
