Femoroacetabular impingement: prospective study of rate and factors related for nerve injury after hip arthroscopy.

Prospective, longitudinal, descriptive study was conducted from January 2016 to January 2018 to detect nerve dysfunction after hip arthroscopy. A total of 110 patients were included. Twenty-four hours after surgery, 62.7% reported symptoms of abnormal sensation at least in one area. The most common was the perineal area. Three weeks after hip arthroscopy, 42.6% still experienced abnormal sensation. Six months after hip arthroscopy, only one patient remained with symptoms. Nerve dysfunction after HA was more common than has been reported in the literature within large populations. Traction time was a significant factor for the development of perineal nerve dysfunction.
