Abstract:
Successful arthroscopic femoroplasty in patients with cam lesions have been reported in Western countries in the last two decades. However, the outcomes after arthroscopic femoroplasty in Asia have thus far only been reported in patients with borderline dysplasia and in the military population. This retrospective study was designed to evaluate the short-term clinical outcomes and radiologic outcomes after hip arthroscopy in patients with cam-type femoroacetabular impingement (FAI) at a minimum postoperative follow-up of 2 years. Methods: From January 2013 to December 2016, 204 hip arthroscopy procedures were performed. Of these cases, 62 patients (73 hips) underwent hip arthroscopy for cam-type FAI. Results: Of the 73 hips, 65 (89.0%) achieved gratified reduction or elimination of preoperative pain. The clinical outcomes showed improvement in scores from before surgery to the last follow-up: 67.1 ± 15.0 to 90.2 ± 6.3 for the modified Harris hip score ( p 〈 0.001), 4.7 ± 2.5 to 7.1 ± 1.4 for the University of California Los Angeles score ( p 〈 0.001), and 7.4 ± 1.9 to 1.8 ± 1.5 for the visual analog scale score ( p 〈 0.001). In radiologic assessments, significant improvement was observed in the alpha angle from a mean 60.9° to 49.5° ( p 〈 0.001) and in the head–neck offset from a mean of 3.3 mm to 6.3 mm ( p 〈 0.001). Of the 73 hips, 65 (89.0%) achieved satisfactory reduction or elimination of preoperative pain. In subgroup analysis for the sufficiency of femoroplasty (alpha angle 〈 55°), the clinical outcomes were not different between the two groups. Conclusion: Arthroscopic femoroplasty resulted in an 89% satisfaction at the 2-year follow-up. Therefore, hip arthroscopic femoroplasty might be an excellent alternative to open surgery and offers a greater probability of good to excellent results.
