Forster-Horvath C, Unterreithmeier U, Fries S, et al. - In this study, the clinical and radiological outcome, a sum of acetabular and femoral cartilage thickness, and rate of failure were assessed in the mid-term following the arthroscopic treatment of femoroacetabular impingement (FAI) syndrome with femoral osteoplasty, labral repair, and rim trimming without labral detachment. Between January 2009 December 2010, researchers conducted a retrospective case series including patients with FAI syndrome who had undergone hip arthroscopy by a single surgeon with a minimum follow-up of 55 months. They conducted 148 hip arthroscopies by a single surgeon, from which 97 cases included rim trimming, labral refixation, and femoral osteoplasty. This study’s findings revealed that arthroscopic cam resection, rim trimming, and labral repair without detachment of the labrum provides a good or excellent outcome in 77.1% of hips based on non-arthritic hip score (NAHS) in the mid-term. There was an association between the higher range of motion in flexion and the higher NAHS postoperatively. For the treatment of FAI syndrome, arthroscopic cam resection, rim trimming and labral repair without detachment of the labrum is a successful method in the midterm.
