Gait Analysis and Clinical Outcomes of Anterior and Lateral Approach Total Hip Arthroplasty.

The goal of this Prospective Randomized Study is to confirm presence or absence of differences in gait mechanics in direct anterior and lateral approaches for total hip arthroplasty. and to compare the clinical outcomes of both approaches. The main questions it aims to answer are: if the anterior approach to the hip is faster recovery than lateral approach? if the anterior approach to the hip has better gait mechanics than lateral approach? Participants will: undergo one of the two approaches for total hip arthroplasty. All patients will be followed up at 2 weeks, 6 weeks, 3 months and 18 months. gait analysis will be done at 6wks, 3m, and 18months.
