Introduction: Osteoarthritis and Osteoporosis are highly prevalent disease, so is hypovitaminosis D. We tried to find out prevalence of osteoporosis and hypovitaminosis D in patients suffering from primary knee Osteoarthritis. We also compared the prevalence of oseotoporosis between general population and patients of primary osteoarthritis.
Methods: Patients suffering from primary knee OA were taken from Rheumatology OPD of Medical College Hospital and SSKM Hospital Kolkata, India. For each patient age and sex matched friend or relative of same locality was taken in the study as controls. Hospital staffs that come from different part of state was taken in the study as controls. The control population was the representative of general population.
Results: Total number of participants in this study was 206. Out of which there were 98 cases and 108 controls. BMD status correlates significantly with Primary OA. Serum Vitamin D3 status correlates significantly with Osteoarthritis. Age of the patients correlated significantly with both BMD Status and Knee OA but not with the vVitamin D level. There were significant correlation between the Serum Vitamin D3 status and BMD of the subjects.
Conclusion: Osteoporosis is prevalent both in general population and patients suffering from Knee Osteoarthritis and may increase the disability. The matter is complicated by the fact hypovitaminosis D is also prevalent in the population and positively correlated with both Osteoporosis and osteoarthrosis, though we cannot comment on further pathogenesis because of cross sectional design of the study.
