The Fragility Index of Hip Arthroscopy Randomized Controlled Trials: A Systematic Survey.

Purpose: To characterize the fragility index (FI) of statistically significant results from randomized controlled trials (RCTs) in hip arthroscopy.

Methods: The PubMed-MEDLINE, Embase, and Cochrane databases were queried for hip arthroscopy RCTs published between January 2010 and July 2020. RCTs were included if they contained only 2 treatment arms, randomized patients to a 1:1 allocation to each arm, and reported at least 1 statistically significant dichotomous outcome.
