Lower preoperative PAM scores were associated with worse improvement in clinical outcomes following MIS LD. Patients with lower PAM scores had diminished improvement in long-term patient-reported outcomes including ODI, SF-12, and VAS back and leg pain. Our investigation suggests that preoperative PAM assessments may be an effective tool to predict postoperative outcomes following MIS LD.
