Prevalence of Generalized Ligamentous Laxity in Patients Undergoing Hip Arthroscopy: A Prospective Study of Patients' Clinical Presentation, Physical Examination, Intraoperative Findings, and Surgical Procedures..

Abstract

Background: Recent studies identified microinstability in the hip as a pathoetiology of painful hip conditions, and it was proposed that generalized ligamentous laxity conditions may predispose patients to such microinstability.

Purpose: To study the relationship of generalized ligamentous laxity with patient characteristics, clinical presentation, intraoperative findings, and surgical treatments in a cohort of patients undergoing hip arthroscopy.

Methods: Registry data were prospectively collected and retrospectively reviewed between February 2014 and November 2017 for patients who underwent primary hip arthroscopy and had a documented Beighton score to assess generalized ligamentous laxity. Patients with a history of an ipsilateral hip condition or ipsilateral hip surgery, those with Tönnis grade >1, and those who had simultaneous arthroscopic and open procedures were excluded from the study. Two comparisons were made between patients with low and high Beighton scores: Beighton 0 vs ≥1 (B 0 vs B ≥1) and Beighton 0-3 vs ≥4 (B 0-3 vs B ≥4). Patient demographics, symptomatology, physical examination, and intraoperative findings were compared between these low and high Beighton groups.
