A recent study has found similar Hip Outcome Score-activities of daily living subscale scores among patients who underwent primary hip arthroscopy performed with looped, pierced or combined labral repair techniques.
Marc J. Philippon, M.D., and his colleagues with the Steadman Philippon Research Institute in Vail, Colo., queried a prospective data registry for adult patients who underwent primary hip arthroscopy with labral repair from 2009 and 2011, and grouped patients on whether they received looped, pierced or combined labral repairs. Researchers performed statistical equivalence testing to evaluate Hip Outcome Score-activities of daily living subscale (HOS-ADL) scores, and also measured HOS-sport subscale, modified Harris Hip scores, SF-12, WOMAC and patient satisfaction scores
Results showed the looped group, the pierced group and the combined group all improved from preoperative scores. Clinicians found all groups had a median patient satisfaction of nine on a scale of one to 10, with 10 denoting very satisfied. At a mean 36-month follow-up, all groups were statistically and clinically equivalent to the validated HOS-ADL to within a clinically irrelevant threshold, according to study results. When it came to secondary outcome measures and revision rate, researchers also found no differences between the looped, pierced and combined groups.
