Comparing mid-term outcomes and patient satisfaction between percutaneous endoscopic lumbar discectomy and microendoscopic discectomy for foraminal and extraforaminal lumbar disc herniations: a retrospective matched cohort study.

ABSTRACT:

Objective

This study aimed to compare the mid-term outcomes and patient satisfaction between percutaneous endoscopic lumbar discectomy (PELD) and microendoscopic discectomy (MED) for the treatment of foraminal and extraforaminal lumbar disc herniations.

Methods

A retrospective matched cohort study was conducted, including patients diagnosed with foraminal or extraforaminal lumbar disc herniations who underwent PELD or MED between January 2014 and December 2021. Patient demographics, clinical characteristics, and perioperative data were analyzed. Primary outcomes included Visual Analog Scale (VAS) scores for pain, Japanese Orthopaedic Association (JOA) scores and improvement rates for functional status, and overall satisfaction at a minimum 2-year follow-up.
