Rosinsky PJ, Kyin C, Maldonado DR, et al. - This study was intended to improve the interpretability of the Nonarthritic Hip Score (NAHS) by ascertaining the minimal clinically important difference (MCID), patient acceptable symptomatic state (PASS), and substantial clinical benefit (SCB) after hip arthroscopy for femoroacetabular impingement (FAI). Researchers distinguished variables associated with the achievement of the thresholds. Between August 2019 and March 2020, researchers enrolled patients who had undergone hip arthroscopy for FAI and completed postoperative questionnaires. Using receiver operating characteristic analysis, distribution and anchor-based methods were utilized to determine the thresholds. Predictors of achieving MCID and PASS were ascertained by performing multivariate logistic regression. A total of 343 hips with an average follow-up of 48 months were included in this study. The results reveal important clinical thresholds for the NAHS. They ascertained these thresholds for minimum one-, two-, and five-year timepoints. As per the results, the MCID was ascertained as 8.7, PASS ranged between 81.9-85.6, and absolute SCB ranged from 91.9-94.4. It was shown that preoperative NAHS was observed to be positively correlated with achievement of PASS and inversely related to the achievement of MCID.
