Abstract
Objective To assess axial (lumbar spine {LS} and femoral neck {FN}) and local tibial BMD by DXA (tibial spine {TS} and internal condylus {IC}) in menopausal women with mild knee OA (kOA). Methods Seventy seven consecutive postmenopausal women (aged 61±5 years, bone mineral indez [BMI] 27.7±3.8 kg/m2) were studied; 81.8% had mild to moderate spine OA (sOA) and 51.9% mild to moderate kOA (Kellgren- Lawrence scale, KLs). Ten women without OA were used to calculate local tibial Z scores. Results Control and OA groups were comparable. Local tibial BMD was increased in kOA patients (Z score; TS: 0.73±1.14 g/cm2, p=0.001; IC: 0.79±2.17 g/cm2, p=0.027), correlating with radiographic rating scale of OA and with axial BMD. 44.1% of patients had densitometric OP. Patients with kOA were older (62±5 vs 60±5 years; p=0.02) and heavier (71.4±10.9 vs 66.0±8.9 kg; p=0.02) versus non-kOA patients. Conclusions Local tibial BMD is increased in menopausal women with mild kOA and this increase is related to radiological score. Local tibial and axial BMD are closely related. The prevalence of OP in these women is very high.
