Description
Xinxiang Tang and six co-authors ask whether the angles of arthritic knees echo in the curve of the lower back, in this 2025 study. Knee osteoarthritis twists the joint's alignment, and patients with back pain alongside it fare worse. The lumbar curve, lordosis, is central to spinal balance and back pain, yet studies rarely connect the two ends of the leg-spine chain.
The team took patients treated during 2023 and measured a battery of angles from their X-rays. The list covered thigh and shin alignment front-on and side-on, joint line tilts, and the lumbar curve. Correlating knee angles with the back's curve tests a clinical intuition, that the body compensates as one column. If bent knees predict a flattened or exaggerated lordosis, a knee clinic's films become a cheap warning for the spine. Surgeons could then plan for the whole posture, not the joint alone.
