Prevalence of Recurrent Herniation Following Percutaneous Endoscopic Lumbar Discectomy: A Meta-Analysis.

Background: Percutaneous endoscopic lumbar discectomy (PELD) is a minimally invasive surgery for the treatment of lumbar disc herniation (LDH) with a smaller incision, decreased damage to soft tissues, faster recovery, and fewer postoperative complications. However, the exactly epidemiological prevalence of recurrent herniation after PELD remains unclear.

Objectives: To investigate the epidemiological prevalence of recurrent herniation in patients following PELD and to analyze the potentially related risk factors.
