Satisfactory Clinical Outcomes and Continuance of Sports After Hip Arthroscopic Labral Repair in Young Competitive Athletes at Minimum 8.5-Year Follow-Up.

ABSTRACT

PURPOSE: To evaluate long-term patient-reported outcomes and achievement rates of patient acceptable symptomatic state (PASS) in young athletes undergoing hip arthroscopy, and to report long-term sports continuance and reoperation. METHODS: Inclusion criteria consisted of age <24 years at surgery, femoroacetabular impingement undergoing primary hip arthroscopy with labral repair, and participation in sport with intent to return to sport after surgery. The enrollment period was from April 2009 to June 2014. Modified Harris Hip Scores (mHHS), Hip Outcome Score (HOS), HOS Activities of Daily Living (HOS-ADL), and HOS Sport (HOS-Sport) were collected preoperatively, 2 years' postoperatively, and final follow-up. Patients were evaluated for PASS achievement, reoperation, and sports participation. RESULTS: Forty-two hips in 37 patients (11 male, 26 female, age 17.7 ± 2.1 years, range 13.6-23.0, body mass index 22.8 ± 2.9, range 17.6-33.7) met inclusion criteria and were followed for 10.0 ± 1.3 years (range 8.5-13.0) postoperatively. Mean mHHS, HOS-ADL and HOS-Sports outcome scores at minimum 8.5 years were 82.2 ± 12.9, 89.6 ± 10.9, and 81.8 ± 16.4, respectively, with significant (P < .001) postoperative improvements. Thirty survey respondents (83%) met PASS for mHHS, 27 (75%) for HOS-ADL, and 24 (67%) for HOS-Sports. At minimum 8.5-year follow-up, only 9 of 37 (24%) cited their hip as the reason for stopping sport. Of the remaining patients, 17 of 28 (61%), continued playing their initial sport. There was no difference in patient-reported outcomes between patients who endorsed sports continuance and patients who did not report sports continuance and did not cite their hip as a reason (P ≥ .229). At final follow-up, 4 hips (10%) had undergone subsequent surgical intervention at a mean of 4.8 ± 3.3 years (range 1.0-8.4) postoperatively. CONCLUSIONS: Durable mid-term outcomes and satisfactory PASS achievement rates are observed in young amateur athletes undergoing primary hip arthroscopy. At minimum 8.5-year follow up, approximately 1 in 4 patients discontinue their sports due to hip related reasons. LEVEL OF EVIDENCE Level IV, case-series.
