Assessment of Functional Outcome between Cemented and Uncemented Total Hip Replacement: A Comparative Study

Abstract

Introduction: Total hip arthroplasty (THA) or total hip replacement is the most effective, economical surgical procedure for femoral neck fractures or hip joint diseases among elderly patients. The main purpose is to reduce pain as well as reduce joint function. Hence, the aim of the present study was to assess the functional outcome between cemented and uncemented total hip arthroplasty. Material and Methods: The present study was an observational study which was hospital-based conducted among 140 cases divided into two groups with 70 cases in each group. All the patients of 50-80 years in which THR was indicated were taken in this study. Patients with neurovascular deficit and active infection were excluded from this study. In Group 1, cemented THR was done while in Group 2 uncemented THR was done. Pain was evaluated using Harris hip score. Results: In cemented group, majority of the cases were avascular necrosis 24(34%) followed by fracture neck of femur 10 (14%), fracture-dislocation of hip 6 (8%) and in uncemented group, maximum cases were avascular necrosis 36 (51%) followed by fracture neck of femur 21 (30%) and fracture-dislocation of hip 14 (20%). mean difference among cemented group was 82.41±7.2 at 6 weeks followed by 81.31±7.5 in uncemented group and this difference was found to be statistically significant at p value 0.001. Conclusion: Cemented implants showed better functional outcomes than uncemented in total hip arthroplasty at 6 weeks, 3 months and at 6 months.
