Background:
Hip arthroscopy is a safe and effective mechanism for treating femoroacetabular impingement symptoms in high level athletes. Bilateral symptoms occur in a subset of this population.
Purpose:
To discuss outcomes of bilateral hip arthroscopy in high-level athletes and compare a standard staged timeline for bilateral hip arthroscopic surgery versus an accelerated timeline.
Study Design:
Cohort study; Level of evidence, 3.
Methods:
A retrospective review of all staged bilateral hip arthroscopies was performed on high-level athletes over a 3-year period. Patients were categorized into cohorts based upon when the second procedure was performed (4-6 weeks after the index procedure or >6 weeks after the index procedure). Exclusion criteria included any prior hip surgery, advanced arthritis, previous pelvic or femoral fracture, or inflammatory arthropathy. Demographics, radiographic measurements, operative reports of procedures performed, and patient-reported outcomes (Hip Outcome Score-Activities of Daily Living, Hip Outcome Score-Sport Specific Subscale, modified Harris Hip Score, return to sports, return to same level of play) were compared between groups at 6-month, 1-year, and 2-year intervals, with the Student t test used for continuous data and a chi-square test used for categorical data.
Results:
50 patients were identified: 22 in the accelerated surgery (AS) group and 28 in the standard surgery (SS) group. Age and number of collegiate participants were greater in the AS group, whereas the number of high school participants and the time away from sports were higher in the SS group. Preoperative alpha angles were significantly larger among the AS group, but no differences were found in postoperative alpha angles, center edge angles, or Tönnis grades. No significant difference was seen in patient-reported outcomes between the 2 groups at 6-month, 1-year, and 2-year follow-up.
Conclusion:
Bilateral hip arthroscopy performed 4 to 6 weeks apart is a safe and effective treatment option for athletes with bilateral femoroacetabular impingement and labral tears; the procedures entail a high rate of return to sports, return to the same level of sports, and decreased time lost from sports. This information could be useful for an athlete deciding on whether to proceed with bilateral hip arthroscopy and deciding on the timing for the procedures.
