Clinical Outcomes after Microdiscectomy for Recurrent Lumbar Disk Herniation: A Single-Center Study.

Background: Revision discectomy is the principal procedure for recurrent lumbar disk herniation (RLDH). The clinical outcomes after this procedure are as good as or slightly poorer than those produced by primary discectomy. In this study, the clinical outcomes of patients treated with microsurgical discectomy for RLDH were analyzed.
