Question 49

What is bench alignment

Answer 49

5 degrees of socket flexion 5 degrees socket adduction foot slightly inset, medial border in parallel to line of progression

Question 50

Why is the socket set to 5 degrees flexion (anteriorly)?

Answer 50

elongates quad --> increase shock absorption during LR
