Background:

Femoroacetabular impingement syndrome (FAIS) is a common cause of hip pain among running athletes. Arthroscopic correction of FAIS has been associated with improvement in hip pain and symptoms as well as return to sport. However, specific outcomes in runners are less defined.

Purpose:

To compare patient-reported outcomes at minimum 2 years after primary hip arthroscopy for treatment of FAIS in running athletes versus nonrunning patients.

Study Design:

Cohort study; Level of evidence, 2.

Methods:

Patients aged 14 years or older who underwent primary arthroscopic osteoplasty and labral treatment of FAIS by a single surgeon at a single academic medical center were entered into the study. Patients were classified as Runners if they listed running as a primary exercise or sporting activity on a baseline activity questionnaire versus Nonrunners who did not. The study included patients with complete preoperative and postoperative Hip Disability and Osteoarthritis Outcome Score (HOOS) subscale scores. Multivariable linear regression was used to determine whether Runner status was a significant independent predictor of postoperative HOOS subscale scores after adjustment for age, sex, body mass index, tobacco use, alpha angle, lateral center edge angle, Tönnis grade, presence of high-grade chondral lesion, and preoperative score.

Results:

A total of 112 patients were included, of whom 36 were running athletes (mean age 33 years; 53% female; mean follow-up 35 ± 11 months) and 76 were nonrunners (mean age 32 years; 55% female; mean follow-up 37 ± 11 months). No baseline differences were found in HOOS subscale scores between the 2 groups ( P > .05). Both groups had clinically and statistically significant improvements in HOOS scores between pre- and postoperative time points (mean change ranged from 15 to 41 points; all P < .001). On multivariable analysis, Runner status was found to be a significant independent positive predictor of higher postoperative scores across all 5 HOOS domains ( P < .05).

Conclusion:

In this cohort analysis, patients with a preoperative self-reported activity of running experienced independently greater improvements in hip outcome scores after arthroscopic treatment of FAIS compared with those who did not report themselves as runners.
