Abstract
Total hip replacement (THR) is a common surgical intervention for patients with hip osteoarthritis (OA) aimed at reducing pain and improving function. This study evaluates the clinical and biomechanical outcomes of THR in hip OA patients preoperatively and at 6 and 12 months postoperatively. A prospective study was conducted on 35 patients undergoing THR for hip OA. Data were collected on pain (Visual Analog Scale‐VAS), hip function (Harris Hip Score‐HHS) and gait parameters (walking speed, stride length, joint angles and ground reaction forces) preoperatively and postoperatively at 6 and 12 months. Statistical analysis included paired t‐tests and Wilcox on signed‐rank tests to determine the significance of changes. The mean age of patients was 55.77 years (SD=9.87) with a mean BMI of 27.50 (SD=4.64)., 51.4% were male. Preoperative VAS was 4.50 (SD=3.05) and HHS was 46.38 (SD=28.90). At 6 months, VAS was 5.10 (SD=3.10) and HHS was 56.78 (SD=25.53)., at 12 months, VAS was 5.21 (SD=2.82) and HHS was 52.26 (SD=28.17). Walking speed improved from 1.06 m/s (SD=0.29) preoperatively to 0.96 m/s (SD=0.34) at 6 months and 1.02 m/s (SD=0.27) at 12 months. Improvements in stride length, joint angles and ground reaction forces were observed but were not statistically significant. Total hip replacement in patients with hip osteoarthritis showed improvements in hip function and gait parameters, although these changes were not statistically significant within the first year post‐surgery. Variability in pain and functional outcomes highlights the need for personalized postoperative care and rehabilitation. Further research with larger sample sizes and longer follow‐up periods is necessary to better understand long‐term benefits and challenges of THR in hip OA patients.
