The Safety and Efficacy of Hip Arthroscopy Performed using a Novel Knotless Suture Anchor

Introduction: Hip arthroscopy is commonly performed for patients with from femoroacetabular impingement (FAI); however, this procedure is technically difficult due to the anatomy of the hip joint and surrounding tissue. The purpose of this study was to evaluate the complication rates of hip arthroscopy procedures for FAI performed using the MICRORAPTOR Knotless Suture Anchor system. Materials and Methods: Retrospective review of consecutive patients undergoing hip arthroscopy for FAI was conducted. All patients underwent labral repair or reconstruction using the MICRORAPTOR Knotless suture anchor. The primary endpoint was any intraoperative or postoperative complication. Descriptive and inferential statistics were performed to assess the patient characteristics and outcomes. Results: Forty-three hip arthroscopies in 42 patients were reviewed at an average of 9 months (standard deviation 4 months) postoperatively; 36 (85.7%) were reviewed at over 6 months postoperatively. At presentation, 90.7% of patients demonstrated a positive anterior impingement sign, 86.0% demonstrated a positive posterior impingement sign, and the median pain numeric rating scale (NRS) was 7.0 ± 4.0 on a scale of 0–10. Four surgeries (9.3%) were revision hip arthroscopies, whereas the remaining 39 (90.7%) were primary labral repairs or reconstructions. Overall, the complications occurred in two (4.6%) cases. The median postoperative pain NRS was reduced from 7.0 ± 4.0 preoperatively to 2.0 ± 6.0 postoperatively (P = 0.003). Conclusion: The MICRORAPTOR Knotless suture anchor appears to be safe for use in patients undergoing hip arthroscopy for FAI.
