ABSTRACT
Introduction: Recently, the patient-reported outcome measures (PROMs) have been considered as the most important assessment tool for surgical outcome evaluation in arthroplasty. However, no study from the Indian subcontinent has evaluated the PROM in the total hip (THA) and knee (TKA) arthroplasties. Materials and Methods: This cross-sectional study evaluated the health-related quality of life (HRQoL) of 1244 North Indian patients following primary THA and TKA who had at least one-year follow-up. This study included 617 patients with 664 THA and 627 patients with 1152 TKA. The patients were asked to answer the EQ-5D-5L questionnaires and EQ-VAS in their own languages. The EQ-5D-5L values were used to derive level frequency scores (LFS) with validated Indian norms of EuroQoL. Results: Ninety percent of THA and 82% of TKA patients rated excellent HRQoL using EQ-VAS. The regression analysis revealed age, gender, etiology and brand of prosthesis had a significant impact on EQ-5D-5L following THA. However, gender and simultaneous bilateral surgery were found to be important predictors of outcome in TKA. The mean value of LFS for THA was 0.95 ± 0.12 and TKA was 0.88 + 0.24 (p < 0.001). However, There was no difference in LFS between THA and TKA when only elderly patients (> 60 years) were considered (p = 0.168). Conclusion: THA patients reported better HRQoL than TKA in the Indian subcontinent. One of the factors for a better outcome in hip arthroplasty was the relatively younger age of the patients. Patients above 60 years of age reported similar levels of statisfactior in both THA and TKA.
