384 Chapter 18 Figure 3 : Cortical bone thickness changes 1 (left) and 2 (middle) years after treatment with knee joint distraction, and 2 years compared to 1 year post-treatment (right), for patients with predominantly medial compartmental osteoarthritis (n=14). Trabecular bone density The trabecular bone density was also higher before treatment on the medial (most affected) side as compared to the lateral side, for both the tibia and femur, for patients with predominantly medial compartmental OA as shown in Figure 4 with green-blue colors. Similarly, the 2 patients with predominantly lateral compartmental OA showed a higher subchondral trabecular bone density at the lateral site as compared to the medial site (Supplementary Figure S2).
