1

3 compartments of the knee

Medial, lateral, patellofemoral

2

Why are Cruciates extra-synovial

Covered in capsule lining

3

Med students ACL

Ligamentum mucosum

4

Lateral knee first layer

IT Band
Biceps

5

Middle lateral knee

Lateral patellofemoral ligament and lateral patellar retinaculum

6

Deep lateral knee

Superficial: LCL and fabelofemoral ligament
Deep: popliteus, popliteofibular ligament, capsule, arcuate ligament

7

Where does the inferior lateral geniculate artery pass*

B/w the superficial and deep lamina of the third layer posterolateral corner

8

First layer of medial knee

Sartorius and deep fascia

9

Second layer of medial knee

Superficial MCL, posterior oblique ligament,
medial paterofemoral ligament, medial patellar retinaculum, semi-M

10

Third layer of medial knee

Deep MCL (meniscofemoral and meniscotibial fibers)
Capsule

11

What attaches medial meniscus to tibial plateu

Coronary ligaments

12

3 layers of meniscus

1. Superficial: woven collagen fiber pattern (circumferential)
2: Surface: randomly
3. Middle (deepest)- radially oriented fibers

13

Where is the lateral meniscus not attached

Popliteal hiatus

14

Two terminal branches of popliteal artery

Anterior and posterior tibial

15

What comes off the lateral cord of the plexus

Lateral pectoral nerve

16

What comes off the posterior cord

Lower subscapualar
Thoracodorsal
Upper subscapular

17

What comes off the medial chord

Medial pectoral
Medial cutaneous nerve of arm
Medial cutaneous nerve of forearm

18

Branch of 1st part of axillary artery

Superior thoracic

19

Branches of 2nd part of axillary artery

Thoracoacromial (clavicular, acromial, deltoid, pectoral)
Lateral thoracic

20

Branches of 3rd part of axillary artery

Subscapular (circumflex scapular)
Anterior circumflex humeral
Posterior circumflex humeral

21

Artery that supplies most of the humeral head

Arcuate artery (branch of anterior circumflex humeral)

22

SGHL FUnction

Resists inferior translation and ER in adduction
Resists posterior translation in 90 of FF

23

MGHL Function

Resists anteroposterior translation in 45 of abduction

24

AIGHL function

Resists anterior and inferior translation in abduction

25

PIGHL Function

Resists posterior translation in IR and 90 FF

26

Biceps pully

SGHL, CHL, and subscaps form anterior pulley to keep biceps tendon located in joint/groove

27

What forms the rotator interval

Triangular space b/w anterior border of supraspinatus and superior border of subscap

28

Rotator interval contents

SGHL, CHL and biceps tendon, antosuperior capsule
