Владивосток, Россия, 690002ABSTRACT Aim. Evaluation of the role of vascular remodeling in the formation of structural phenotypes of osteoarthritis (OA). Materials and methods. 62 patients with OA aged 65,9±8,8 years and 18 volunteers without clinical and roentgenologic signs of OA aged 60,7±7,9 years were examined. All patients underwent magnetic resonance imaging of knee joints. To analyze the structural changes in the tissues of the knee joint, the WORMS protocol was used for magnetic resonance imaging. The thickness of the vascular wall, the external diameter, the vascular index (VI) were measured -the ratio of the diameter of the lumen of the vessel to the thickness of the popliteal artery (PA) wall, the branch of the upper lateral artery (LA), the medial artery of the knee (MA).Results. The analysis of the parameters of the arteries of the knee joint showed that with a subchondral OA phenotype, the thickness of the PA wall is statistically significantly larger than the cartilage phenotype, and the vascular index of the PA is significantly higher in the group of the cartilaginous phenotype. The upper LA wall was significantly thicker in the subchondral OA phenotype. VI of the upper LA was significantly lower in patients with a subchondral phenotype compared

Locomotive syndrome'' is defined as a condition associated with restriction in one's ability to walk or lead a normal life due to a dysfunction in one or more of the parts of the locomotion system, including the muscles, bones, joints, cartilage or intervertebral discs. This syndrome especially refers to individuals who have come to need nursing care services because of problems with the locomotive organs, or those who have conditions which may require them to need such services in the near future. Recent epidemiological studies revealed that the one-fourth of elderly individuals who require special assistance or nursing care have locomotive disorders in Japan. Osteoarthritis of the knee (knee OA) and hip (hip OA), and osteoporosis and spinal canal stenosis due to spondylosis are three major locomotive disorders that cause elderly individuals require special assistance or nursing care. In this review, we focus on the effects of knee and hip OA on the lives of elderly individuals and the recent advantages in clinical research on the pathophysiology and management of these diseases.
