Used to assess for ligamentous laxity of the medial (deltoid) and lateral (ATF) ligaments​

Varus test (aka Talar Tilt Test)​:

• Supporting the proximal ankle, hold the talus and calcaneus as one unit and apply a varus force to the ankle, causing inversion​
• Positive test when pain and ligamentous laxity are appreciated. May appreciate a “clunk”​

Valgus test​:

• Supporting proximal ankle and holding talus and calcaneus as a unit, apply a valgus force to the ankle, resulting in eversion​
• Positive with pain and excessive movement
• Supporting proximal ankle and holding talus and calcaneus as a unit, apply a valgus force to the ankle, resulting in eversion​
• Positive with pain and excessive movement

With both of these tests, always compare both sides by testing the non-injured ankle first.
