Core Tip

Core Tip: Sagittal spinopelvic alignment (SSA) plays a critical role in maintaining upright posture and mobility. While spinal alignment changes are known to cause compensatory shifts in the pelvis, hips, and knees, few studies have explored the reverse relationship, particularly in patients undergoing total knee arthroplasty (TKA), with inconclusive findings. SSA represents a complex interaction among pelvic, spinal, and lower limb structures. Although TKA can improve knee flexion contractures, it may not fully address lumbar lordosis, especially in individuals with concurrent spinal degenerative conditions, limiting overall sagittal correction.
