This study investigated the relationship between preoperative pelvic tilt and postoperative outcomes in patients undergoing hip preservation surgery for FAIS or hip dysplasia. We reviewed a prospective hip preservation database for demographic, radiographic, and outcome data for 89 patients who underwent hip preservation surgery with a primary diagnosis of FAIS or dysplasia from 2016 to 2020. Pelvic tilt was assessed on the standing anteroposterior radiograph with the pubic symphysis to sacroiliac joint (PS-SI) distance measurement. The International Hip Outcome Tool 12 (iHOT-12), Hip Outcome Score, Harris Hip Score, UCLA activity score, and European Quality of Life\u2013Visual Analog Scale were used to assess hip function and pain preoperatively and postoperatively. The mean pelvic tilt (PS-SI distance) was 86.4\u00b118.3 mm for the FAIS group and 96.2\u00b115.1 mm for the dysplasia group. The statistical analysis demonstrated a positive relationship between pelvic tilt and change in iHOT-12 score (<jats:italic>r<\/jats:italic><jats:sub>s<\/jats:sub>=0.262,<jats:italic>P<\/jats:italic>=.019) for all 89 patients with hip pathology and, separately, a trend toward significance for the 42 patients with FAIS (<jats:italic>r<\/jats:italic><jats:sub>s<\/jats:sub>=0.330,<jats:italic>P<\/jats:italic>=.056). No other significant relationships were observed. The improvement in iHOT-12 score was greater for patients with more anterior tilt and less for patients with posterior pelvic tilt, regardless of underlying hip etiology. These results provide intriguing insights into an initial investigation on pelvic tilt in patients undergoing hip preservation surgery. Further investigation is necessary to assess pelvic tilt preoperatively and postoperatively, spinal parameters, and longer-term outcomes.
