Recurrent lumbar disc herniation after discectomy: outcome of repeat discectomy

The outcomes of repeat discectomy for recurrent disc herniation were satisfactory. No factors such as age, sex, traumatic events, times of prior surgery, level of herniation, side of recurrence, pain-free interval, duration of recurrence symptoms, walking capacity, the preoperative JOA score, associated spinal stenosis, procedures of revision surgery, and dural tear were found to be of predictive value for a prognosis of revision surgery for recurrent disc herniation (P > .05).
