Quizplus · Accepted Answer

The medial collateral ligament (MCL) is the primary stabilizer of the elbow to valgus stress between 20° and 120° flexion. It is a thick, strong ligament on the inside of the elbow joint that provides stability against forces pushing the elbow outwards, or in a valgus direction. The other options, including the quadrate ligament, oblique cord, and annular ligament, do not play a significant role in stabilizing the elbow joint during valgus stress.
