Introduction: Hip osteoarthritis is a major public health issue associated with a considerable loss of Health-related Quality of Life (HR-QoL). However, not all patients achieve the same level of functional improvement after Total Hip Arthroplasty (THA) and it is unclear which factors are associated with it. Aim: To determine the functional outcome and QoL in patients who underwent Total Hip Replacement (THR) in an Indian set-up. Materials and Methods: The present prospective cohort study was conducted in the Department of Orthopaedics, Eras Lucknow Medical College and Hospital, Uttar Pradesh, India, from March 2020 to September 2021. A total of 100 patients who underwent THA were included through convenience sampling. Demographic and clinical information, like name, age, gender, Body Mass Index (BMI), duration of symptoms, co-morbidity, Visual Analogue Scale (VAS) score and Western Ontario and McMaster Universities Arthritis Index (WOMAC) scores, were noted from the medical records. A single follow-up of all the patients who underwent THA was conducted to assess the complications, functional outcomes and QoL using VAS score (preoperative and postoperative), WOMAC score (preoperative and postoperative), Harris Hip Score (HHS) (postoperative), Short Form-36 (SF-36) health survey (postoperative) questionnaire. The data was analysed using Statistical Package for the Social Sciences (SPSS) software version 25.0. Continuous variables were analysed using the Wilcoxon signed-rank test for paired data. Correlation assessment was done using Pearson’s correlation coefficient for continuous factors and Spearman’s correlation coefficient for categorical factors. Results: The average age of the patients who underwent THR was 58.90±15.93 years, with a range of 17-95 years. There were 72 males and 28 females. The mean VAS score preoperatively was 7.41±1.20, which decreased significantly to 2.93±0.81 in the postoperative follow-up (p-value<0.001). The mean total WOMAC score improvement was 38.51±10.26 (p-value<0.001). The average postoperative HHS was 73.53±16.16, suggesting a good outcome. The average postoperative SF-36 score was 68.89±12.88. A correlation coefficient of 0.21 (p-value=0.033) suggested that the WOMAC score improvement became higher with an increase in follow-up duration. Patients with postoperative complications had a significantly lower WOMAC improvement (r-value=-0.26, p-value=0.0084). It was observed that the follow-up duration (p-value=0.047) and postoperative complications (p-value=0.016) were significant factors of WOMAC score improvement. Conclusion: Follow-up duration and the presence of postoperative complications were important factors in the functional outcome of patients who underwent THA. Knowledge of these factors can help the clinician to plan the management accordingly while counseling the patients and their relatives regarding any possible adverse outcomes.
