Figure 1 Small cartilaginous Aβ2m deposits (arrowheads;A and B) and massive cartilaginous Aβ2m deposits (C and D); anti-β2m immunoperoxidase (left) and anti-CD68 immunoperoxidase (right). There is an absence of macrophagic infiltration (magnification ×250).

Figure 4 Schematic representation of the three stages of Aβ2m deposition. Aβ2m is represented in black (bone A, cartilage B, capsule C, synovium D). Macrophages accumulate around synovial Aβ2m in stage III.
