TOP: Maximum isokinetic torque and corresponding knee angle values (mean and 95% confidence intervals) separated for the operated (OP) and non-operated (nOP) leg as well as the 60°/s and 180°/s velocity. BOTTOM: Linear relationships between the conventional HQ-ratio and the angle-specific HQ-ratios separated for the operated (OP) and non-operated (nOP) leg as well as the 60°/s and 180°/s velocity. Note: dotted lines mark the locations of the maximum values
