Fig. 6From: A novel rat model of stable posttraumatic joint stiffness of the kneeBox plots of extension deficits. Extension deficit (ED, left picture), arthrogenic extension deficit (AED, middle picture), and myogenic extension deficit (MED, right picture) of operated knee joints vs. controls. The difference in extension deficit between an intervention group and its control is defined as contracture. A highly significant difference between an operation group and the respective control is indicated by a hashtag (#p < 0.01). A significant difference between operation groups is marked by an asterisk (*p < 0.05, **p < 0.01)Back to article page
