Functional outcome of total hip arthroplasty after a previous hip arthroscopy: a retrospective comparative cohort study.

Background: Despite patients demonstrating significant short-term clinical improvement from a hip arthroscopy (HA), a number of patients progress to significant osteoarthritis of the hip requiring total hip arthroplasty (THA). This study aims to evaluate if there is any difference in the functional outcome of patients undergoing THA after a previous hip arthroscopy compared to patients undergoing THA for primary osteoarthritis of the hip.

Methods: Between 2010 and 2013, in a group of 414 patients who underwent hip arthroscopy, we identified 18 patients who underwent a subsequent uncemented THA.
