Abstract
ObjectiveTo analyze the broadband ultrasound attenuation (BUA), speed of sound (SOS), standard deviation of bone density (T-Score) and stiffness index (SI) with bone mineral density (BMD) in elderly female patients with knee osteoarthritis and their diagnostic efficacy of osteoporosis.
MethodsFifty elderly female patients with knee osteoarthritis admitted o Tangshan People′s Hospital from January 2021 to January 2022 were selected as the observation group, and 40 healthy female patients during the same period were selected as the control group. The results of BUA, SI, T-score and SOS in observation group and control group were analyzed and compared. The BUA, SI, T-score and SOS in elderly women with knee osteoarthritis at different ages and with different bone densities were compared, and the diagnostic value of BUA, SI, T-score and SOS in osteoporosis was analyzed by receiver operating characteristic (ROC) curve.
ResultsThe BUA, SI and T-score of observation group were lower than that in the control group, while SOS was higher than that in the control group (all P<0.05). Among elderly female patients with knee osteoarthritis of different ages, the older the age, the lower the BUA, SI and T-score (all P<0.05), while there was no statistical significance in SOS of elderly female patients with knee osteoarthritis of different ages (P>0.05). In elderly women with knee osteoarthritis with different BMD grades, the BUA, SI, and T-score in the osteoporosis group were lower than those in the osteopenia group and the normal bone group, and the BUA, SI, and T-score in the osteopenia group were lower than those in the normal bone group; the SOS in the osteoporosis group was higher than those in the osteopenia group and the normal bone group, and the SOS in the osteopenia group was higher than those in the normal bone group (all P<0.05). BUA, SOS, T-score and SI had high sensitivity and specificity in the diagnosis of osteoporosis in elderly women with knee osteoarthritis (all P<0.05).
ConclusionsBMD in elderly women with knee osteoarthritis is associated with BUA, SI, T-score, and SOS, and has high diagnostic value for osteoporosis.
