ABSTRACT
PURPOSE: To evaluate symptom duration and its relationship to patient reported outcomes and survivorship following hip arthroscopy in adolescents.
METHODS: Patients ≤18 at time of primary hip arthroscopy for FAI between January 2011 and September 2018 were included. Exclusion criteria consisted of history of previous ipsilateral hip surgery, presence of osteoarthritis or dysplasia on preoperative radiographs, previous hip fracture, or history of slipped capital femoral epiphysis or Legg-Calve-Perthes disease. Minimum 2-year patient-reported outcomes (modified Harris Hip Score (mHHS), Hip Outcome Score (HOS)-Activities of Daily Living (ADL), HOS-Sport Scale (SSS), Short Forms 12 (SF-12)), minimum clinically significant difference (MCID) and patient acceptable symptom state (PASS) rates, and revision surgery rates, were compared based on symptom duration.
RESULTS: Two-year minimal follow-up was obtained for 111 patients (134 hips) (80%), including 74 females and 37 males with mean age of 16.4±1.1 (range: 13.0-18.0). The mean symptom duration was 17.2±15.2 months (range: 43 days to 6.0 years). Ten patients (11 hips), 6 females (7 hips) and 4 males, required revision surgery at an average of 2.3±1.0 years (range, 0.9 to 4.3 years). At a mean follow-up of 4.8±2.2 years (range, 2 to 10 years), there were statistically significant improvements in all PROs (p<.05 for all). Symptom duration showed no significant correlation to post-operative scores (correlation coefficient range: -0.162 to -.078, p>0.05 for all). Symptom duration <12 months versus >12 months or as a continuous variable was not a predictor for requiring revision surgery or achieving MCID/PASS (95% Confidence Interval crosses 1 for all).
CONCLUSION: In an adolescent cohort of symptomatic FAI patients who underwent hip arthroscopy, there is no difference in patient reported outcome measures when analyzing symptom duration by arbitrary time intervals or as a continuous variable.
