Background: Percutaneous endoscopic lumbar discectomy (PELD) has been widely used for treating lumbar disc herniation. Recurrence after PELD has been reported, but few studies have focused on the risk factors responsible for recurrence after PELD.

Methods: This retrospective study enrolled 116 patients with recurrent herniation after successful PELD from March 2005 to March 2016. Kaplan-Meier method and Cox regression analysis were employed to identify significant risk factors predicting recurrence after PELD.
