Meniscal dimensional measurements in a pig stifle joint representative of all measurements recorded across species. Panel a shows the two circumference measurements along the periphery of the meniscal body (grey solid semi-circular line) and the whole periphery (dotted black semi-circular line), and the width of the meniscal body as measured from the three locations, indicated with black solid lines. Panel b shows the three locations for the peripheral height, arranged from right to left: anterior, middle and posterior third. Panel c shows a cross-sectional view at the mid-point in a pig meniscus demonstrating the superior articular length (red solid curved line) and the articulating height (black vertical lines) at the four measurement points (A, B, C and D)
