Akpinar B, Lin LJ, Bloom DA, et al. - The present study was performed to evaluate the prognostic impact of lumbar spinal stenosis on clinical outcomes after hip arthroscopy for femoroacetabular impingement syndrome (FAI). Between September 2009 and December 2015, individuals undergoing hip arthroscopy for FAI with concomitant lumbar spinal stenosis (central/neuroforaminal) and a 2-year follow-up were distinguished (hip-spine). A total of 26 patients were included in the study. The results indicated that the presence of concomitant lumbar spinal stenosis negatively affects postoperative PROs while net PROs from baseline improve after hip arthroscopy for FAI. The findings considered that FAI patients with spinal stenosis should be counseled accordingly.
