Table 2 Myogenic vs. arthrogenic components of extension deficit (ED). Angles are presented as means ± standard deviation. Contracture is displayed as the difference in extension deficit between intervention group and the respective control
From: A novel rat model of stable posttraumatic joint stiffness of the knee
