We studied 50 knees of 25 women patients with bilateral varus osteoarthritis of the knee to determine the
relationship between the bone mineral density (BMD), body-mass index (BMI) and varus deformity. The mean
age of patients were 66,6. Four angles were measured to assess the varus deformity of each knee: The
femorotibial (FT) angle, the femoral condylar-femoral shaft (FC-FS) angle, the femoral condylar-tibial plateau
(FC-TP) angle, the tibial plateau-tibial shaft (TP-TS) angle. The FC-FS/FT, FC-TP/FT and TP-TS/FT angles
were also calculated to determine which component angle was predominant in the varus deformity. BMD of the
L2-L4 spinal region was measured, by dual photon x-ray absorptiometry. Body-mass index (BMI), an indicator of
obesity, was calculated. BMD/BMI was also calculated to determine the influence of body mass on BMD.
In statistical evaluation of results a correlation was found between severity of varus osteoarthritis and low BMD
and BMD/BMI (r= -0.486, p
