PATHOLOGY OF LOWER EXTREMITY VEINS IN OSTEOARTHRITIS OF KNEE JOINTS
Based on a thorough clinical and instrumental study, establish a possible association between osteoarthritis (OA) of the knee joints (KJ) and lower extremity vein pathology (LVC). A case-control study was conducted including women 45-65 years old. The main group included 75 women with OA KJ and the control group included 40 women without OA KJ. Patients of both groups underwent evaluation of complaints and targeted objective examination to detect joint diseases and chronic VNS diseases, X-ray examination of the KJ, and duplex scanning of the VNS. Varicose vein disease (VWD) of the lower extremities (42% vs 23%; p=0.016) and signs of chronic venous insufficiency (29% vs 11%; p=0.04) were diagnosed more frequently in female patients with OA KJ than in the control group. Duplex scanning of NK revealed a generalized lesion of VNK (bilateral lesion of great saphenous vein and small vein valves, severe degree of valve insufficiency), which was revealed in 52% of patients in this group versus 20% of the control group (p=0,0005). After correction for body mass index, differences in the incidence of CH between the groups remained clinically and statistically significant (odds ratio 2.8 at 96% confidence interval from 1.2 to 6.8; p=0.037). In female patients with OA KC aged 45-65 years with VB NK, signs of chronic venous insufficiency develop more frequently than in their healthy female peers. Although obesity is a risk factor for both diseases, there is an independent association between OA KJ and CHF.
