METHODS: Patients with normal sagittal alignment and normal motion (PI-LL 10°) were defined as control, and patients with any of sagittal alignment or motion abnormalities were defined as case groups. Visual Analog Scale, SF-36, Harris hip score, HOOS-JR, and complications were recorded.
RESULTS: The differences of the means of Harris hip score, HOOS-JR, SF-36, and VAS score in the control and case groups were statistically significant. The mean of these parameters in patients with sagittal balanced (PI-LL 10°). Same results were noted in patients with decreased (∆SS 10°).
CONCLUSION: Our observations indicate that spinopelvic imbalances are associated with worse postoperative functional outcomes in patients undergoing total hip arthroplasty.
