Introduction: Lumbar disc herniation (LDH) is a prevalent condition that can cause radiculopathy and leg pain. Full-endoscopic lumbar discectomy (FELD) has emerged as a minimally invasive alternative to microdiscectomy, offering similar clinical efficacy with potentially reduced recovery times. Degenerative disc disease (DDD) is frequently observed in patients undergoing surgery, yet its influence on surgical early outcomes of FELD remains unclear. Methods: This prospective study included 91 patients who underwent FELD for single-level LDH between January 2022 and March 2024. Patients were classified in two groups based on Pfirrmann grade: grade inferior to 4 (Group 1) and grade 4 or 5 (Group 2). Clinical outcomes were assessed using the Numeric Rating Scale (NRS) for back and leg pain preoperatively and at 2, 14, 30, and 90 days postoperatively, and the Oswestry Disability Index (ODI) preoperatively and at 30 and 90 days postoperatively. Results: = 0.041). Postoperatively, both groups experienced significant pain relief, but Group 1 showed superior back pain improvement across all time points. No significant differences were observed in ODI scores or leg pain improvement. Discussion: Patients with moderate disc degeneration (Pfirrmann grade 3) exhibited greater preoperative back pain but experienced superior back pain relief after FELD compared with those with advanced degeneration (Pfirrmann grade 4 or 5).
