Hip and Knee Joints

Question 1

Which is the inverted Y-shaped ligament?

Answer 1

iliofemoral ligament

Question 2

Where is the iliofemoral ligament attached to?

Answer 2

proximal attachment- AIIS

distal attachment- intertrochanteric line

Question 3

which artery traverses the iliofemoral ligament?

Answer 3

an articular branch from the deep branch of the medial femoral circumflex artery

Question 4

Where does the pubofemoral ligament attach?

Answer 4

obturator crest and the superior ramus (anterior border of the iliopectineal eminence) of the pubis to proceed inferolaterally to blend in with the fibers of the iliofemoral ligament

Question 5

Where does the ischiofemoral ligament attach?

Answer 5

(is triangular in shape and found on the posterior side of teh capsule)
-its fibers spring proximally from the body of the ischium posterior and inferior to the acetabulum

Question 6

what is the function of the iliofemoral, pubofemroal, and ischiofemoral ligament?

Answer 6

prevent hyperextension of hip joint

Question 7

which ligament is seen in the head of the hip joint?

Answer 7

ligamentum capitis femoris

Question 8

which ligament makes the acetabular notch into a foramen?

Answer 8

transverse acetabular ligament

Question 9

is the LCL attached to the lateraL meniscus?

Answer 9

no- the popliteal tendon lies in btwn

makes it unstable

Question 10

is teh MCL attached to the medial meniscus?

Answer 10

yes

Question 11

Which structures lie superficial to the MCL?

Answer 11

SGT muscles
sartorius
gracilis
semitendinosus

Question 12

which muscle provides fibers to the oblique popliteal ligament?

Answer 12

semimembranosus

Question 13

what direction does the oblique popliteal ligament run?

Answer 13

runs superolaterally

Question 14

the arcuate popliteus ligament is formed by what ?

Answer 14

thickening over the popliteus muscle

Question 15

which ligament acts to prevent hyperextension of the knee joint?

Answer 15

ACL

Question 16

which ligament acts to prevent hyperflexion of the knee joint?

Answer 16

PCL

Question 17

which intra-capsular ligament is stronger (ACL or PCL)?

Answer 17

PCL

Question 18

what does the transverse ligament attach?

Answer 18

attaches the menisci to the tibia anteriorly

Question 19

are the menisci attached to the tibia or teh femur?

Answer 19

tibia

Question 20

what is the coronary ligament in the knee joint?

Answer 20

attachment of capsule to teh meniscus

Question 21

what is the only bursa that communicates with the knee joint?

Answer 21

suprapatellar bursa

Question 22

what is the “unhappy triad” of knee joints?

Answer 22

MCL torn
medial meniscus torn
ACL torn

Question 23

what ligament does posterior drawer sign test for?

Answer 23

damage to PCL - which normally prevents hyperflexion of the knee

Question 24

which ligament does the anterior drawer sign test for?

Answer 24

ACL- normally prevents hyperextension of the knee

Question 25

what type of joint is the knee joint?

Answer 25

condyloid joint- allows hinge, gliding, and some rotational movement

Question 26

the articular capsule of the knee joint is incomplete where?

Answer 26

anteriorly- it is replaced by the medial and lateral retinaculi of the quadriceps tendon

Question 27

where does the ACL attach?

Answer 27

anterior intercondylar area of the tibia (it is named for its attachment) and runs superolaterally to attach to the posterior part of the medial surface of lateral femoral condyle

Question 28

if found, the anterior and posterior meniscofemoral ligaments are found attached to which meniscus?

Answer 28

from lateral meniscus and extends to the medial condyle of the femur
