Abstract: Total hip arthroplasty evolved as a result of many improvements in design of femoral head prosthesis, the availability of suitable component materials and manufacturing techniques, a better understanding of hip mechanics, and the need for resurfacing the acetabulum. Charnley did pioneering work in all aspects of total hip arthroplasty, including the concept of low frictional torque arthroplasty, surgical alteration of hip biomechanics, lubrication, materials, design, and operating room environment. A retrospective study was conducted on 30 hips of 22 patients who underwent primary uncemented total hip arthroplasty for advanced arthritis for various indications at the Department of orthopaedics. The most common indication for surgery was avascular necrosis of femoral head in 21 hips (70%) in 13 patients. The other causes being secondary arthritis due to non- union fracture neck of femur in 4 hips ( 13.3%), ankylosing spondylitis in 3 patients (10%), perthes disease and developmental dysplasia of hip group had 1 patient (3.3%) each.
