Sport Participation Is Associated with Superior 10-Year Patient Acceptable Symptom State Achievement Following Contemporary Hip Arthroscopy for Femoroacetabular Impingement.

BACKGROUND

Sport participation has been associated with favorable outcomes following hip arthroscopy (HA) for femoroacetabular impingement (FAI) at short- and mid-term follow-up; however, few studies have evaluated the 10-year outcomes in this population. The purpose of this study was to compare patient-reported outcome measures (PROMs), the achievement of clinically significant outcomes, and reoperation-free survivorship between patients with and without regular preoperative sport participation who underwent HA for FAI and had a minimum of 10 years of follow-up.

METHODS

Data were prospectively collected for patients who underwent primary HA for FAI between January 2012 and September 2013. Patients who participated in weekly sport participation at the time of surgery ("athletes") were matched 1:1 to patients who denied sport participation ("nonathletes"), controlling for age, sex, and body mass index (BMI). Preoperative and 10-year postoperative PROMs were collected, including the Hip Outcome Score Activities of Daily Living (HOS-ADL) and Sports (HOS-Sports) subscales, the modified Harris hip score (mHHS), and the visual analog scale for pain (VAS Pain) and satisfaction (VAS Satisfaction). Patient acceptable symptom state (PASS) achievement and reoperation-free survivorship were compared between the groups.

RESULTS

Sixty-four athletes were matched to 64 nonathletes of similar age, sex, and BMI (p ≥ 0.411). In the athlete group, 85.9% were recreational-level athletes. The groups had similar preoperative PROMs, except for the HOS-ADL subscale, where the athlete group demonstrated a higher preoperative score (67.8 ± 16.7 versus 59.9 ± 21.1, p = 0.029). Both groups demonstrated a significant improvement in all PROMs (p < 0.001) at the minimum 10-year follow-up10.3 ± 0.4 years). At the time of the final follow-up, the athlete group demonstrated significantly higher scores across all of the measured PROMs (p ≤ 0.036). Athletes showed a higher cumulative PASS achievement compared with nonathletes for the HOS-ADL subscale (73% versus 50%, p = 0.033), the HOS-Sports subscale (85% versus 61%, p = 0.010), the mHHS (69% versus 43%, p = 0.013), and the VAS Pain (78% versus 51%, p = 0.006). Reoperation-free survivorship frequencies were 87.5% and 82.8%, respectively (p = 0.504).

CONCLUSIONS

Athletes who underwent contemporary HA for FAI showed superior PROMs and PASS achievement compared with nonathletes at the 10-year follow-up. Athletes and nonathletes showed reoperation-free survivorship frequencies of 87.5% and 82.8%, respectively.
