Difference in Muscle Strength and Functional Outcome in Direct Lateral Approach versus Posterior Approach in Total Hip Arthroplasty: A Prospective Cohort Study.

Background And Purpose: The choice between posterior approach (PA) and direct lateral approach (DLA) for total hip arthroplasty (THA) remains a contentious issue regarding clinical outcome optimization and restoring patient function. Previous studies have evaluated the postsurgical outcomes mostly in the form of Harris hip score (HHS), and the data to objectively measure the postoperative muscle power is scarce. We intend to objectively compare the hip abduction and extension strengths and other functional outcomes with a very simple tool in PA and DLA in the Indian population as most patients do not undergo as intensive rehabilitation in the postoperative period as in the western world.
