Outcomes for Hip Arthroscopy Based on Gender and Age: A Comparative Matched-Group Analysis

Abstract

The purpose of this study was to compare the clinical outcomes of patients undergoing hip arthroscopy for femoroacetabular impingement (FAI) based on between sex and age. A total of 150 patients undergoing hip arthroscopy for FAI by a single fellowship-trained surgeon were prospectively analyzed, with 25 patients categorized in each of the following groups: A) females ≤30 years, B) females 31-45 years, C) females >45 years, D) males ≤30 years, E) males 31-45 years and F) males >45 years. Primary clinical outcomes included the Hip Outcome Score Activity of Daily Living (HOS-ADL) and Sport-Specific Subscales (HOS-SS), the modified Harris Hip Score (mHHS), and clinical improvement at final follow-up. Statistical analysis was performed utilizing ANOVA and student's paired and unpaired T-tests, with P At a minimum 2-year follow-up, all groups demonstrated significant improvements in HOS-ADL, HOS-SS, and mHHS outcomes at final follow-up (P45 scored significantly worse on the HOS-ADL, HOS-SS, and mHHS compared to females ≤30 (P45 scored significantly worse on the HOS-ADL, HOS-SS, and mHHS compared to males ≤30 (P=0.016, P45 scored significantly better than females >45 on the HOS-SS (P=0.019) and the mHHS (P=0.029). Incorporating both genders, patients >45 scored significantly worse on the HOS-ADL, HOS-SS, and mHHS compared to patients ≤30 (P While all patients had significant improvements in all outcomes following hip arthroscopy for FAI, patients >45 performed worse compared to patients in younger age groups, with females >45 demonstrating the poorest outcome scores. Overall, care must be individualized to optimize outcomes following hip arthroscopy for FAI.
