Abstract	Background: Primary total hip arthroplasty (THA) is performed to relieve pain and restore function in patients with advancedhip pathology. Patient-reported and clinician-based outcome measures provide an objective assessment of recovery. Thisstudy evaluated functional outcomes following primary THA at a tertiary care centre. Methods: A prospective observational study was conducted in the Department of Orthopaedics, VDGMC, Latur, fromJanuary 2023 to December 2024. Fifty patients aged 45–85 years undergoing primary THA were included. Functional outcome was assessed using the Harris Hip Score (HHS) and WOMAC Index. Patients were assessed preoperatively andduring postoperative follow-up. Radiographs were used to assess implant position and complications. Statistical analysisused paired testing for preoperative and postoperative continuous outcomes, with p<0.05 considered statistically significant. Results: Fifty patients were included; 32 (64%) were male and 18 (36%) female. Mean age was 62.4±9.7 years. Indicationswere avascular necrosis in 30 (60%), fracture neck of femur in 12 (24%), primary osteoarthritis in 7 (14%), and inflammatoryarthritis in 1 (2%). Uncemented implants were used in 38 (76%) and cemented implants in 12 (24%). Mean HHS improvedfrom 43.8±6.2 preoperatively to 64.7±5.9 at 6 weeks, 78.3±6.7 at 3 months and 88.6±7.1 at 6 months (p<0.001). At 6months, 21 patients (42%) had excellent, 20 (40%) good, 7 (14%) fair and 2 (4%) poor HHS results. WOMAC pain, stiffness,physical function and total scores also improved significantly (all p<0.001). Reported complications included superficialinfection (4%), dislocation (2%), deep-vein thrombosis (2%) and transient nerve palsy (2%); 90% had no recorded complication. Conclusion: In this single-centre cohort, primary THA was associated with substantial improvement in hip function, pain andphysical function by 6 months. Early mobilization and structured rehabilitation were integral to recovery. Larger multicentrestudies with longer follow-up are required to assess predictors of outcome and implant survivorship.
