Degenerative changes of the knee often cause loss of extension. This may affect aspects of posture such as lumbar lordosis. A total of 366 patients underwent radiological examination of the lumbar spine in a standing position. The knee and body angles were measured by physical examination using a goniometer. Limitation of extension of the knee was significantly greater in patients whose lumbar lordosis was 30 degrees or less. Lumbar lordosis was significantly reduced in patients whose limitation of extension of the knee was more than 5 degrees. It decreased over the age of 70 years, and the limitation of extension of the knee increased over the age of 60 years. Our study indicates that symptoms from the lumbar spine may be caused by degenerative changes in the knee. This may be called the 'knee-spine syndrome'.

Background: Adults with spinal deformity (ASD) are known to have spinal malalignment, which can impact their quality of life and their autonomy in daily life activities. Among these tasks, ascending and descending stairs is a common activity of daily life that might be affected.
Research Question: What are the main kinematic alterations in ASD during stair ascent and descent?
Methods: 112 primary ASD patients and 34 controls filled HRQoL questionnaires and underwent biplanar X-from which spino-pelvic radiographic parameters were calculated.

To analyze the influence of cervical range of motion on the preferable sagittal vertical axis in ankylosis spondylitis (AS)-related thoracolumbar kyphosis following single-level pedicle subtraction osteotomy (PSO). The clinical data of sixty-five AS patients who underwent single-level PSO from February 2012 to November 2018 in the Drum Tower Hospital of Nanjing University Medical School were retrospectively reviewed. Of the patients, 59 were males and 6 were females with a mean age of (34.

Purpose: This study aims to investigate how aspirin influences lumbar degeneration by analyzing the effect of aspirin on patients with low back pain (LBP) and concurrent atherosclerosis.
Methods: Using 1:1 nearest neighbor matching based on propensity score matching (PSM), 73 patients who regularly took aspirin were assigned to the aspirin group, while another 73 patients who did not take aspirin formed the control group. Radiographs were used to measure lumbar lordosis (LL) and intervertebral height index (IHI).
Spinopelvic malalignment correlates to lumbar instability and lumbar musculature in chronic low back pain-an exploratory study.

As PI-LL mismatch is an effective index for spinal surgery and PI-LL less than 10 probably indicates better quality of life, this study aimed to assess spinopelvic parameters, lumbar instability, and lumbar muscle morphology in patients with chronic low back pain (CLBP) with different PI-LL mismatches. This cross-sectional study included 158 CLBP patients. The association between lumbar extensor muscle morphology (measured from magnetic resonance imaging) and spinopelvic parameters (measured from standing lateral radiographs) and lumbar instability (measured from lumbar flexion/extension radiographs) was compared between two groups of patients with different PI-LL mismatch.
