1
Q

which part of femur is in knee joint?

A

distal portion

2
Q

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

A

tibia: big, medial; fibula: small, lateral

3
Q

what is unique about knee joint?

A

largest single joint in human body

is actually 3 joints

4
Q

joints of knee joint

A

patella-femur (1 joint)

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

5
Q

what are menisci, how many in knee, where?

A

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

6
Q

which meniscus is larger?

A

lateral

aka “o shaped” meniscus

7
Q

ligaments around knee joint?

A

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

8
Q

what does quadriceps tendon attach to?

A

tibial tuberocity

9
Q

bursae of knee?

A

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
Q

which bursa is most clinically significant, why?

A

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
Q

what is infrapaterlla fold

A

embryonic remnant from when knee cavity was separated off

12
Q

which meniscus attaches to which ligament?

A

medial meniscus-ACL, MCL

13
Q

what comprises unhappy triad of the knee?

A

ACL, MCL, medial meniscus

14
Q

does lateral collateral ligament attach directly to lateral meniscus?

A

no

15
Q

poplitius muscle function?

A

initial flexor/unlocker of knee jiont

its tendon runs between LCL and knee joint
