<p class="abstract"><strong>Background: </strong>Study aimed to assess and compare the functional outcome in patients underwent the large femoral head THA and conventional femoral head THA.</p><p class="abstract"><strong>Methods:</strong> It is a comparative prospective cross sectional study conducted among the patients undergoing primary total hip arthroplasty through postero-lateral approach at department of orthopaedics Vydehi institute of medical sciences, Bengaluru during the period of July 2017 to July 2019. Patients aged between 18-80years of both genders undergoing Primary THA for Osteoarthritis (OA), Rheumatoid Arthritis (RA), Ankylosing Spondylitis (AS), Post traumatic arthritis, Avascular necrosis (AVN), Acute fracture neck of femur, Non-union fracture neck of femur (NOF). Patients undergoing primary total hip arthroplasty in Intertrochanteric fracture, Acetabular fracture and patients undergoing Revision Hip Arthroplasty were excluded from study. Patients were grouped as the ones treated with large femoral head THA and conventional femoral head THA.</p><p class="abstract"><strong>Results: </strong>This series consisted of 36 patients with 44 diseased hips treated with primary total hip arthroplasty (THA). Out of 36 patients, 9 patients (25%) belonged to an age group of below 30 years of age, 10 patients (27.8%) belonged to the age group between 31-40 years of age, 8 patients (22.2%) belonged to the age group 41-51 years of age and 9 patients (25%) belonged to age group of 51-60 years of age. The mean level of Modified Harris Hip score and improvement of movements in all planes was found to be statistically significantly in the patients treated with large femoral head primary THA compared to those treated with conventional method. (p<0.001)</p><p class="abstract"><strong>Conclusions: </strong>Study has shown improved functional outcome (Modified harris hip score) and range of movement in the patients treated with the large femoral head primary THA as compared to those treated with a conventional femoral head.</p>
