Oswestry Disability Index (ODI) scores and Japanese Orthopaedic Association (JOA) scores at admission and 104 weeks postoperatively in the 4 groups. The lowest ODI score corresponds to the best functional state. The JOA recovery rate was calculated according to the following formula: (104-week follow-up score - preoperative JOA score)/(29 - preoperative JOA score) × 100%. P<0.05 in JOA recovery rate (group A vs. group B).
