1 Cancellous bone differences between knees with early, definite and advanced joint space loss; a comparative quantitative macroradiographic study  Elizabeth A. Messent, Ph.D., Rupert J. Ward, Ph.D., Carol J. Tonkin, DCR(R), Christopher Buckland-Wright, D.Sc.  Osteoarthritis and Cartilage  Volume 13, Issue 1, Pages (January 2005) DOI: /j.joca Copyright © 2004 OsteoArthritis Research Society International Terms and Conditions

2 Fig. 1 Macroradiograph (4×) of a proximal right tibia showing placement of the medial (M) and lateral (L), subchondral (Sc) and subarticular (Sa) for FSA. Diameter of ball-bearing=5mm. Broken lines represent the inferior margin of the cortical plate.

3 Fig. 2 The mean difference in FD for vertical (i) and horizontal (ii) trabecular structures between OA groups (OA1 —, OA2 ––, OA3 –·–) and the non-OA group (NOA) in the medial subchondral (a) and subarticular (b) regions. Significant differences indicated at P<0.05 , P<0.01 ■, and P<0.001 □.

4 Fig. 3 The mean difference in FD for vertical (i) and horizontal (ii) trabecular structures between OA groups (OA1 —, OA2 ––, OA3–·–) and the non-OA group (NOA) in the lateral subchondral (a) and subarticular (b) regions. Significant differences indicated as described in Fig. 2. Osteoarthritis and Cartilage  , 39-47DOI: ( /j.joca ) Copyright © 2004 OsteoArthritis Research Society International Terms and Conditions

5 Fig. 4 Macroradiographic (4×) image of a left proximal non-OA (a) and OA tibia (b). Subarticular osteoporosis, manifested as increased radiolucency, is visible in the lateral and particularly medial tibial compartments in (b). Diameter of ball-bearings=5mm.
