Actual Exam Questions and CORRECT
Answers
What is Q angle (patellofemoral angle) - CORRECT ANSWER- ✔✔The angle between the
quadriceps muscle (primarily the rectus femoris muscle) and the patella tendon
Male/female differences in Q angle - CORRECT ANSWER- ✔✔The angle tends to be
greater in females because the pelvis is generally wider in women
Normal Q angle - CORRECT ANSWER- ✔✔Knee extension ranges from 13-19 degrees in
normal individuals
Genuvarum - CORRECT ANSWER- ✔✔Bowlegged/ problem in which the distal segments
are positioned more medially than normal
Genuvalgum - CORRECT ANSWER- ✔✔knock knees/ problem in which the distal segments
are positioned more laterally than normal. Knees tend to touch while ankles are apart.
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 - CORRECT ANSWER-
✔✔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 - CORRECT ANSWER- ✔✔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: - CORRECT ANSWER- ✔✔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 - CORRECT ANSWER- ✔✔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 ------> - CORRECT ANSWER- ✔✔which becomes femoral artery--->
which becomes popliteal artery--->
which becomes anterior/posterior tibial artery--->
which becomes dorsalis pedis artery
Popliteal space and structures - CORRECT ANSWER- ✔✔Popliteal space- the area behind
the knee and it contains important nerves (tibial and common fibularis) and blood vessels
(popliteal artery and vein)
Bound superiorly on the medial side by medial hamstrings and lateral hamstrings
