Examinations of patients following total knee replacement revealed that those who continued to report knee stiffness were more likely to have sagittal spinal malalignment. The researchers suspect that postural abnormalities in the spine may lead to compensatory changes in the biomechanics of the knee and a resulting reduction in range of motion. Doctors of chiropractic are trained to assess the whole patient to identify any factors that may contribute to a patient’s chief complaint and treat them with conservative options including manipulation, mobilization, specific exercises, modalities, and nutritional recommendations.
