Regardless of the preoperative predominant pain location, patients undergoing UBE-LD reported significant improvements in physical function, back and leg pain, and disability. Patients in both cohorts demonstrated improvements in mental health outcomes, with comparable MCID achievement rates for VR-12 MCS. These findings suggest that UBE-LD might be effective for patients with both predominant back and leg pain presentations, although differences in specific outcome domains should be interpreted with caution due to potential selection bias. Consideration of predominant pain location might help inform preoperative patient counseling regarding expected outcomes following UBE-LD.
