A graph shows external tibial rotation in response to a 5-Nm external rotation force at 30° and 90° of knee flexion in Group II. Sectioning of the LCL, PFL, popliteus, and PCL were required to generate an increase in external rotation at both 30° and 90° of knee flexion. Comp = compartment; POP = popliteus tendon.
