Background The purpose of this study was to compare the clinical outcome of surgery using robot‐assisted posterior interbody fusion with that using freehand posterior interbody fusion in patients with degenerative spinal disease. Methods 78 participants with degenerative spinal disease were randomly allocated (1:1) to the minimally invasive (MIS), posterior lumbar interbody fusion (Robot‐PLIF) or conventional, freehand, open‐approach, posterior lumbar interbody fusion (Freehand‐PLIF). Results The baseline‐adjusted scores on the Oswestry Disability Index (ODI) in both groups at 1 year after surgery were not different ( P = 0.688). However, the decrease in disc height at the proximal adjacent segment was significantly less in the Robot‐PLIF group than in the Freehand‐PLIF group ( P = 0.039). Conclusion One‐year surgical outcomes including Visual Analog Scale, ODI and Short Form‐36 did not differ between the two groups. The disc height in the proximal adjacent segment was significantly less decreased in the Robot‐PLIF group than in the Freehand‐PLIF group.
