Since the correlation between spinal and lower extremity alignments is high, high
tibial osteotomy (HTO) surgery may also affect spinal alignment, where the spinal
alignment parameters are the most important parameters for the evaluation of
spinal disorders. In this study, the effect of HTO surgery on spinal alignment
during gait was investigated by comparing spinal alignment parameters between
patients with knee osteoarthritis (OA) and healthy young controls. Eight patients
(age, 55.0+/-5.1years; height, 160.3+/-7.0cm; weight, 71.3+/-14.1kg) with a
medial compartment knee OA participated in the gait experiment two times
approximately one week before and one year after HTO surgery and eight healthy
young controls (age, 26.7+/-1.7years; height, 163.4+/-6.5cm; weight,
58.4+/-11.3kg) participated only once. Cervical curvature angle, thoracic
curvature angle, lumbar curvature angle, coronal vertical axis, and coronal
pelvic tilt in the coronal plane and cervical lordosis, thoracic kyphosis, lumbar
lordosis, sagittal vertical axis, and sagittal pelvic tilt in the sagittal plane
were estimated using motion analysis system with skin markers. All spinal
alignment parameters after HTO surgery were significantly closer to those of
healthy young subjects than those before HTO, especially in the coronal plane.
These findings suggest that the HTO had a positive effect on spinal alignment, as
well as lower extremity alignment, and moreover, reduced the abnormality that may
result in spinal problems such as degeneration or pain.
