| Abstract |
Objective
The purpose of our study was to measure and describe the bilateral hip bone mineral density (BMD)
differences in knee ortheoarthritis (OA) patients and to determine the associations of such differences with the
severity of knee OA.
Methods
Study comprised 56 women over the age of 65 diagnosed with knee OA, and who had their spine and hip
BMD determined from July 2007 to April 2009. After the symptomatic knee site was determined, the hip BMD value
of the leg with the symptomatic knee was compared with that of the contralateral hip. We also investigated the
associations of BMD difference with patient age, body mass index, bilaterality of pain, grades of radiographic change,
knee functional score, presence of vertebral compression fracture and diagnosis of osteoporosis.
Results
Patients had a lower hip BMD on the symptomatic knee side compared with that of the contralateral hip (P
< 0.05). We found no correlations between BMD difference and patient age, body mass index, bilaterality of pain,
presence of vertebral compression fracture and diagnosis of osteoporosis, but it was positively correlated with grade
of radiographic change and negatively correlated with knee functional score.
Conclusions
We suggest that knee OA should be considered as a factor of hip BMD difference and the hip BMD of
the affected side should be measured for the diagnosis of osteoporosis in women over the age of 65.
