Background: Total hip replacement (THR) remains the definitive surgical intervention for end-stage hip arthritis. While numerous studies have documented its effectiveness, continuous evaluation of outcomes helps refine surgical techniques and patient selection criteria. This prospective study assessed the clinical outcomes, patient satisfaction, and complications in 100 consecutive cases of primary total hip replacement.

Methods: Between January 2022 and December 2023, 100 consecutive patients with hip arthritis underwent primary total hip replacement at our institution. The cohort included both osteoarthritis (85%) and rheumatoid arthritis (15%) cases. All procedures were performed using a standardized posterior approach. Outcomes were evaluated using the Harris Hip Score (HHS), Visual Analog Scale (VAS) for pain, Oxford Hip Score (OHS), and EQ-5D-5L quality of life questionnaire. Radiological assessment and complication rates were documented over a 12-month follow-up period.

Results: The mean age of patients was 65.3±8.7 years, with a female predominance (58%). Harris Hip Scores improved significantly from a preoperative mean of 42.5±7.8 to 88.7±6.4 at twelve months (p<0.001). Pain scores decreased from 7.8±1.2 to 0.8±0.7 on the VAS (p<0.001). Patient satisfaction was high, with 95% reporting satisfaction with their outcomes. Radiological analysis showed optimal component positioning in 98% of cases. The overall complication rate was 7%, including one case each of prosthetic joint infection and dislocation. Multiple regression analysis identified younger age, lower BMI, better preoperative function, and absence of rheumatoid arthritis as significant predictors of favorable outcomes.

Conclusion: This study demonstrates that standardized total hip replacement techniques yield excellent clinical outcomes and high patient satisfaction rates at one-year follow-up. The identified predictive factors for outcomes may help optimize patient selection and preoperative counseling. Future studies with longer follow-up periods are warranted to assess the durability of these results.
