Purpose
To report minimum 2-year patient-reported outcome scores (PROs) and return to sport
(RTS) for competitive athletes undergoing primary hip arthroscopy for femoroacetabular
impingement syndrome within 1 year of symptom onset and to compare these results with
a propensity-matched control group of competitive athletes with symptoms for over
1 year.
Methods
Data on professional, collegiate, high-school, and organized amateur athletes who
underwent primary hip arthroscopy within 1 year of symptom onset between April 2008
and November 2017 were collected. RTS and minimum 2-year PROs were collected for the
modified Harris Hip Score (mHHS), Non-arthritic Hip Score (NAHS), Hip Outcome Score-Sport
Specific Subscale (HOS-SSS), International Hip Outcome Tool (iHOT-12), and visual
analog pain scale (VAS). Rates of achieving minimal clinically important difference
(MCID) were also evaluated. These patients were propensity-matched to a control group
of competitive athletes with symptoms for over one year for comparison.
Results
Fifty competitive athletes (51 hips, 54.9% female) were included in the study group
with a mean follow-up of 70.9 ± 29.1 months and age of 23.6 ± 11.3 years. They demonstrated
significant improvement from preoperative to latest follow-up for all recorded PROs
(P < .001) and RTS at a rate of 72.9%. When outcomes were compared to the control group,
the study group demonstrated similar preoperative scores for all PROs but significantly
better minimum 2-year postoperative scores for NAHS (93.8 vs 85.1, P = .0001), HOS-SSS (89.1 vs 77.2, P = .001), iHOT-12 (87.7 vs 76.4, P = 0.011), and VAS (1.5 vs 2.4, P = 0.027). Rates of achieving MCID for HOS-SSS and mHHS were comparable between groups.
Further, RTS rates were similar between groups (P = .301).
Conclusion
Competitive athletes undergoing primary hip arthroscopy with symptoms for less than
1 year demonstrated superior 2-year PROs compared to a propensity-matched control
group with symptoms for over 1 year, but the rates achieving MCID and RTS were similar
between groups.
Level of Evidence
Level III, retrospective comparative study.
