Surgical restoration of lumbar lordosis (LL) may reduce increased pelvic tilt (PT), while the influence factors of PT restoration (rPT) remain unclear. This study aimed to identify potential factors affecting rPT in LDD surgery and its correlation to postoperative clinical outcome.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>161 LDD patients underwent surgical treatment were included. Sagittal parameters were measured in whole spine radiographs in standing and sitting. Changes from standing to sitting were denoted as \u0394. The LL restoration (rLL) and rPT was calculated as postoperative - preoperative values. Clinical outcomes were evaluated using the visual analogue scale (VAS) and Oswestry Disability Index (ODI). The influence factors of rPT were analyzed, and the sagittal parameters affecting post-operative ODI, leg pain VAS and low back pain VAS was examined.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      rLL (r=-0.403), PT (r=-0.375), SS (r=0.400), L4-S1 lordosis (r=0.324), LL (r=0.319) and TPA (r=-0.291) in standing, \u0394PT (r=0.304) and \u0394SS (r=-0.254) was significantly related to rPT.
