USAHS Anatomy LE Test Exam

Questions with 100% Correct Answers


What is Q angle (patellofemoral angle) - ✔✔The angle between the

quadriceps muscle (primarily the rectus femoris muscle) and the patella

tendon

Male/female differences in Q angle - ✔✔The angle tends to be greater in

females because the pelvis is generally wider in women

Normal Q angle - ✔✔Knee extension ranges from 13-19 degrees in normal

individuals

Genuvarum - ✔✔Bowlegged/ problem in which the distal segments are

positioned more medially than normal

Genuvalgum - ✔✔knock knees/ problem in which the distal segments are

positioned more laterally than normal. Knees tend to touch while ankles are

apart.

Genurecurvatum - ✔✔Back knees/ hyperextension, ROM goes beyond 0

degrees extension

During an open chain knee extension what kind of rotation takes place in

tibia in relation to femur? For example, the tibia rotates laterally on the

femur. During open chain knee extension, Femur does not rotate on tibia,

but tibia rotates on femur. On the other hand, during closed chain reaction,

the femur rotates on tibial condyle - ✔✔Open chain- the knee has a

concave on convex relationship where the concave tibial condyles glide

posteriorly with flexion and anteriorly with extension, while the distal end of

the tibia moves in the same direction



Closed chain- the knee has a convex on concave relationship, but is

reversed when non weight bearing

When you come up from sit to standing, what happens at the end of knee

extension (now this is the closed chain reaction). At the end of knee

extension, the femur spins (medially or laterally) to lock into place for

optimal standing stability - ✔✔When going from sit to stand, the femur must

glide posteriorly on the tibia as it rolls into extension



At the end of knee extension, the femur spins/rotates medially on the tibia

What is the patellofemoral pain syndrome? What are the common causes

of the syndrome, some examples include: - ✔✔Patellafemoral pain

syndrom: a common problem causing diffuse anterior knee pain and

around the knee cap

Common causes- overuse, improper use of sports equipment,

misalignment of patella, muscle imbalance, and tightness in anatomical

structures

Generally considered the result of a variety of alignment factors

Femoral triangle fig 7-11 - ✔✔Bordered by the inguinal ligament superiorly,

the sartorius laterally, and adductor longus medially



The femoral artery, vein, nerve, numerous lymph nodes, and terminal

portion of great saphenous vein lie within the triangle



Pectineus and iliopsoas muscle form the floor of the triangle

External iliac artery ------> - ✔✔which becomes femoral artery--->

which becomes popliteal artery--->

which becomes anterior/posterior tibial artery--->

which becomes dorsalis pedis artery
