Eligibility

Inclusion criteria

Inclusion criteria: 1. Primary elective total hip arthroplasty. 2. Patients requiring cemented or uncemented THA. 3. Patients with diagnosis of hip osteoarthritis, avascular necrosis, rheumatoid arthritis, or fracture neck of femur requiring THA. 4. Patient willing to be a part of the study by giving due informed consent. 5. Patients who are declared fit for appropriate anaesthesia by the department of anaesthesia.

Exclusion criteria

Exclusion criteria: 1. Patients requiring Revision THA 2. Patients with prior surgeries around the hip that could alter pelvic anatomy. 3. Patients with fracture acetabulum, protrusion acetabulum, hip dysplasia and ankylosis hip 4. Patients requiring acetabular reconstruction or augmentation 5. Tumors, or severe deformities involving the pelvis or proximal femur. 6. Intraoperative complications that alter the planned procedure (e.g., unanticipated fractures). 7. Patients with neuromuscular conditions affecting hip joint stabilty. 8. Inability to undergo follow-up imaging, or poor-quality images unsuitable for angle measurement. 9. Lack of compliance or withdrawal of consent during the study period.
