High Rate of Return to Running for Athletes After Hip Arthroscopy for the Treatment of Femoroacetabular Impingement and Capsular Plication.
BACKGROUND
Femoroacetabular impingement (FAI) is most commonly diagnosed in athletes who sustain repetitive flexion loading to their hips. No studies to date have focused solely on patients' return-to-running ability after hip arthroscopy.


OBJECTIVE
To evaluate patients' ability to return to running after hip arthroscopy for FAI and capsular plication.


METHODS
Case series; Level of evidence, 4.


METHODS
Clinical data were retrospectively retrieved for 51 consecutive patients with FAI (22 men, 29 women) who had undergone hip arthroscopy for the treatment of FAI and identified themselves as recreational or competitive runners on intake forms. Two-year outcome measures included the modified Harris Hip Score (mHHS) and the Hip Outcome Score Activities of Daily Living (HOS-ADL) and Sport-Specific (HOS-SS) subscales. A postoperative return-to-running survey was used to obtain running-specific information.


RESULTS
Patient age and body mass index (BMI) were a mean (±SD) of 26.3 ± 7.8 years and 23.7 ± 3.3 kg/m2, respectively. Before surgery, patients had refrained from running because of pain for a mean of 8.1 ± 5.7 months. After surgery, 48 patients (94%) returned to running at a mean of 8.5 ± 4.2 months. Patients who had discontinued running for more than 8 months before surgery had a longer return-to-running time than did those who had stopped for less than 8 months (10.6 ± 4.2 vs 7.6 ± 4.1 months; P = .01). After 2 years, mean preoperative distance had decreased significantly ( P < .01) from 9.5 ± 6.5 miles per week when healthy to 6.4 ± 5.8 miles postoperatively. Despite decreased mileage, all 2-year outcomes scores improved significantly ( P < .001).


CONCLUSIONS
Recreational and competitive runners with FAI returned to running 94% of the time at a mean of 8.5 months after hip arthroscopy. However, runners should be counseled before their surgery that they may run fewer miles than when they were pain free. Additionally, patients with a higher BMI and/or longer preoperative lull may have a longer recovery time.
