Question 2

excessive genu valgum

Answer 2

Answer 5

Flexion ~130-140 deg
Extension ~5-10 deg beyond straight

Question 6

Medial Collateral Ligament

Answer 6

Resists valgus, resists knee extension, and resists extremes of axial rotation (especially knee external rotation)

Question 7

Lateral Collateral Ligament

Answer 7

Resists varus, knee extension, and extremes of axial rotation (probably more ER)

Question 8

ACL

Answer 8

Increasingly taut in extension; resists ant. tib translation, tib IR, obliquely oriented

Question 9

PCL

Answer 9

Increasingly taut in flexion; resists post. tib translation, more vertical than ACL
