Abstract
Total hip arthroplasty (THA) is an established therapeutic intervention for advanced degenerative and traumatic hip disorders. While both cemented and cementless fixation techniques are widely used, their comparative influence on therapeutic effectiveness, pharmacologic utilization, and population-level clinical outcomes in routine clinical practice remains incompletely characterized. To compare therapeutic and functional outcomes, postoperative pharmacologic requirements, and population-level clinical outcomes between cemented and cementless total hip arthroplasty. A retrospective comparative cohort study was conducted at SCB Medical College, Cuttack, a tertiary care hospital, from January 2023 to January 2025, involving 120 patients who underwent primary total hip arthroplasty. Patients were equally divided into cemented (n = 60) and cementless (n = 60) fixation groups. Data on demographic characteristics, postoperative pain scores, functional outcomes, medication utilization, complications, mortality, and length of hospital stay were extracted from medical records. Statistical analyses included descriptive statistics, independent t-tests, correlation analysis, and multivariate linear regression. Both fixation techniques resulted in significant improvement in postoperative pain relief and functional recovery, with comparable long-term outcomes. Cemented THA was associated with lower pain scores at discharge and shorter duration of postoperative analgesic use compared with cementless THA (p < 0.001). Length of hospital stay was significantly shorter in the cemented group. Correlation analysis demonstrated a moderate positive association between postoperative pain intensity and analgesic duration (r = 0.46, p < 0.001). Regression analysis identified cementless fixation, higher pain scores, and prolonged analgesic use as independent predictors of longer hospital stay. Cemented and cementless THA provide comparable long-term therapeutic benefits; however, cemented fixation is associated with reduced early postoperative pain, lower pharmacologic burden, and shorter hospitalization. These findings highlight the importance of integrating therapeutic and population-level considerations in fixation selection.
