Decreased hip labral width measured via preoperative MRI is associated with inferior outcomes for arthroscopic labral repair for femoroacetabular impingement
Arthroscopy Aug 25, 2020
Kaplan DJ, Samim M, Burke CJ, et al. - This study was intended to ascertain the relationship between labral width as measured on preoperative MRI with hip-specific validated patient self-reported outcomes at a minimum of 2 years follow-up. Researchers conducted an IRB-approved retrospective review of prospectively gathered hip arthroscopy patients from 2010 to 2017. This study characterized inclusion criteria as patients > 18 years old with radiographic evidence of femoroacetabular impingement who underwent a primary labral repair and had a minimum of 2 years of clinical follow-up. This analysis included a total of 103 patients (107 hips) (mean age 39.4 ± 17 years; BMI 25.0 ± 4; 51% right-sided; 68% female; mean follow-up 76.5 months ± 19.1, range 30.0 to 113.0 months). Via preoperative MRI, Hip labral width < 1 standard deviation below the mean measured was correlated with significantly worse functional outcomes following arthroscopic labral repair and treatment of FAI. The data illustrate that the negative association between labral width and outcomes may be non-linear.
