evaluation of bone mineral density in patients undergoing total hip arthroplasty and total knee arthroplasty

Background: osteoarthritis and osteoporosis are the most prevalent musculoskeletal disorders (msds) in middle aged and elderly individuals and affect their quality of life (qol). the presence of both these disorders is rarely reported in an individual patient. this study was conducted with the aim to assess this association using dual-energy x-ray absorptiometry (dexa) as a measure of bone mineral density (bmd) in patients undergoing hip and knee arthroplasty.methods: between august 2015 and august 2018, 71 patients were selected as the study participants. the inclusion criteria included age of higher than 50 years and presence of ‎primary or secondary arthritic conditions. the exclusion criteria were age of below 50 years, prolonged steroid intake (3 months), metabolic disease, and performance of ‎arthroplasty for the management of fractures. results: the incidence rate of osteoporosis was found to be higher in higher age groups of patients undergoing arthroplasty. furthermore, there was no statistical difference in the t-scores with respect to the sex of the patients.conclusion: osteoarthritis and osteoporosis can occur simultaneously in an individual. the development of osteoarthritis does not prevent the development of generalized osteoporosis in an individual patient.
