Knee osteoarthritis, a common condition in postmenopausal women, is due to obesity and increased bone hypertrophy and osteophytes. Osteoporosis is a gradual loss of bone after menopause. The two conditions are often found simultaneously.
Objectives of the study: To determine the osteoporosis rate in women with knee osteoarthritis and to investigate risk factors for osteoporosis in patients with knee osteoarthritis.
Methods: Osteoporosis and risk factors for osteoporosis are assessed in 68 patients with postmenopausal knee osteoarthritis.
Results: The proportion of women with knee osteoarthritis associated with osteoporosis was 37/68 (54.4%). There were 46/68 patients (67.6%) with muscle mass index – SMI below 6.75. The skeletal muscle index in the osteoporosis group was 6.25 ± 0.75. Vitamin D deficiency was found in 57/68 patients (83,8%).
Conclusion: The proportion of women with knee osteoarthritis associated with osteoporosis accounted for 54.4%. The following factors: age, low weight, and low muscle mass, affect osteoporosis in women with knee osteoarthritis.
