Flashcards in Knee Video Deck (15):
1

which part of femur is in knee joint?

distal portion

2

which is big/small re: tibia, fibula, and lateral/medial?

tibia: big, medial; fibula: small, lateral

3

what is unique about knee joint?

largest single joint in human body
is actually 3 joints

4

joints of knee joint

patella-femur (1 joint)
medial-lateral condyles of femur and tibia (2 joints)

5

what are menisci, how many in knee, where?

fibrocartilagenous discs that increase articular efficiency of the joint
2- medial, lateral
attach directly to tibia

6

which meniscus is larger?

lateral
aka "o shaped" meniscus

7

ligaments around knee joint?

1) anterior cruciate ligament
2) posterior cruciate ligament
3) medial/tibial collateral ligament
4) lateral/fibular collateral ligament

8

what does quadriceps tendon attach to?

tibial tuberocity

9

bursae of knee?

1) pre-patella fossa/bursa, in front of patella
2) infrapatella bursa, below
3) quadriceps bursa/suprapatella bursa/large quadriceps bursa, under quadriceps m.

10

which bursa is most clinically significant, why?

large quadriceps bursa / quadriceps bursa / suprapatella bursa
around knee joint, under quadriceps m.
large space communicates directly w/ knee joint cavity
infections can spread to cavity proper thru here

11

what is infrapaterlla fold

embryonic remnant from when knee cavity was separated off

12

which meniscus attaches to which ligament?

medial meniscus-ACL, MCL

13

what comprises unhappy triad of the knee?

ACL, MCL, medial meniscus

14

does lateral collateral ligament attach directly to lateral meniscus?

no

15

poplitius muscle function?

initial flexor/unlocker of knee jiont
its tendon runs between LCL and knee joint
