What is inferior What is superior
200
During terminal stance what position is the knee joint in?
What is 0 degrees of flexion and moving into extension
200
The mechanism for an ACL rupture is...
What is forced flexion combined with rotation (either lateral or medial)
300
This part of the capsule secretes and absorbs synovial fluid into the joint for lubrication & nutrition to avascular structures
What is the synovial layer of the joint capsule
300
What muscle tenses the iliotibial band?
What is the tensor fascia latae
300
