INTRODUCTION: The aim of this study was to examine the satisfaction and associated factors in patients aged 65 years and older, who underwent surgery for lumbar spinal stenosis (LSS), up to the 1‐year postoperative phase.

PATIENTS AND METHODS: Sixty‐four patients (mean age 75 years, men 34%) with symptomatic LSS were included. Data collection took place with the same set of questionnaires before surgery and 1 year postoperatively. Postoperative satisfaction was assessed with the two‐item visual analog scale (full satisfaction 100mm): 1. Did you satisfy with the surgical results? 2. Did you want to receive the same surgery? In addition, patients' preoperative expectation, comorbidity, depression scale, pain, numbness and points of five subscale calculated from Japanese Orthopaedic Association Back Pain Questionnaire (JOABPEQ), which consists of pain‐related disorder, lumbar spine dysfunction, gait disturbance, social life disturbance and psychological disorder were assessed. Multiple regression analysis was used to examine a predictor of postoperative satisfaction.

RESULTS: Mean satisfaction 1 and 2 were 78.5mm and 64.2mm, respectively. Two statistical significant models were obtained: Satisfaction 1 = 39.3 + 0.3 × acquired points of gait disturbance + (‐0.3 × postoperative leg numbness) + 0.3 × preoperative leg pain + 0.2 × preoperative points of lumbar spine dysfunction (R = 0.8) and Satisfaction 2 = 33.4 + 0.5 × postoperative points of social life disturbance + (‐0.45 × postoperative leg numbness) + 0.35 × preoperative points of lumbar spine dysfunction (R = 0.7). There were no statistical relationships between the satisfaction, preoperative expectation and depression scale.

DISCUSSION: Preoperative lumbar spine dysfunction and postoperative leg numbness were predictor factors of patients' satisfaction. It is possible that early surgical intervention for elderly LSS patients with lumbar spine dysfunction and leg numbness improves the postoperative satisfaction.
