The Effect of the Severity of Preoperative Leg Pain on Patient Reported Outcomes, MCID Achievement, and Patient Satisfaction Following MIS-TLIF.

Patients with severe preoperative leg pain demonstrated worse postoperative PROM scores and patient satisfaction for disability and back/leg pain. MCID achievement rates across cohorts were similar. Patients with severe leg pain may have expectations for surgical benefits incongruent with their postoperative outcomes, and physicians may seek to manage the preoperative expectations of their patients to reflect likely outcomes following MIS-TLIF.
