Flashcards in Knee and Leg Deck (47):
0

Type of joint - knee

Modified hinge joint
Because it will rotate to lock the knee joint in the last few degrees of extension

1

Weight-bearing bone of the leg

Tibia

2

The patella is what kind of bone

Sesamoid bone

3

Patellar stabilizers

Vastus medialis, lateral patellar condyle, joint facets

4

Synovial lining of the knee that is continuous with the synovial membrane capsule of the knee

Suprapatellar bursa

5

How many bursa are present around the knee?

At least 12

6

Suprapatellar Bulge

Excess fluid inside the knee

7

Swelling of the semimembranosus or synovial bursa behind the knee joint

Baker's Cyst

8

Stabilizes the medial area of the knee, against valgus force

Medial collateral ligament/tubular collateral ligament

9

Stabilizes lateral area of the knee, against varus force

Lateral collateral ligament/fibular collateral ligament

10

Contributes to the knees anteroposterior stability

Anterior cruciate ligament and posterior cruciate ligament

11

Space-filler analogous to labrum in the knee

Menisci

12

Static Stabilizers of the Knee

MCL, LCL, PCL, ACL, MENISCI

13

Dynamic Stabilizers of the Knee

Extensor mechanism, biceps femoris, iliotibial tract, pes anserinus, semimembranosus, oblique popliteal ligament, popliteus, medial and lateral head of gastrocnemius

14

Knock-kneed, piki, toes pointing inward

Coxa valga, genu valgum

15

Components of the pes anserinus

(SGT)
Semitendinosus, Gracilis, Sartorius

16

Bow-legged, sakang, toes pointing outward

Coxa vara, genu varum

17

Caused by eroded menisci

Osteoarthritis

18

Area where quadriceps femoris inserts via patellar tendon

Tibial tuberosity

19

Bone that carries most of the body weight

Tibia

20

The tibia superiorly articulates with the ____, and inferiorly with the ____.

Superior: femoral condyle
Inferior: talus

21

[T/F] the fibula has no articulation on the surface of the knee

T

22

Firmly attaches the fibula to the tibia

Tibiofibular syndesmosis

23

Anterior fascial compartment paralysis

Results to inability to dorsiflex, exhibiting a foot drop

24

Fasciotomy

Surgical procedure where the muscle fascia is cut to relieve tension or pressure

25

Muscles of the anterior compartment

PETE: Tibialis anterior, extensor hallucis longus, extensor digitorum longus, peroneus (fibularis) tertius

26

Role of anterior compartment muscles

Dorsiflexion of the ankle and extensor of toe

27

Strongest dorsiflexor

Tibialis anterior

28

Most lateral of the anterior leg muscles, inserts into 2nd to 5th toes

Extensor digitorum longus

29

Extends the big toe

Extensor hallucis longus

30

[ACTION] peroneus tertius

Contributes weakly to dorsiflexion, pronation/eversion of foot, contracts reflexively to protect anterior talofibular ligament

31

Most commonly sprained ligament of the body

Anterior talofibular ligament

33

Muscles of the lateral compartment

Peroneus/fibularis longus, peroneus/fibularis brevis

33

Connects the two heads of the gastrocnemius

Aponeurosis

34

Muscles of the posterior compartment

Superficial posterior: gastrocnemius, soleus, plantaris (ankle plantarflexors)

Deep posterior: popliteus, flexor hallucis longus, flexor digitorum longus, tibialis posterior

35

Needed for push-off phase of walking

Gastrocnemius

36

Components of the triceps sure

Gastrocnemius and soleus

37

Part of the leg that is commonly used as a tendon graft

Plantaris

38

Workhorse of plantarflexion

Soleus

39

Role of popliteus

Forms the interior part of the floor of the popliteal fossa

40

Deepest and most anterior muscle in the flexor compartment

Tibialis posterior

41

Muscles that form the stirrup at the base of the foot

Tibialis posterior and peroneus longus

42

Number of weeks needed to heal an Achilles Tendon Rupture

6-12 weeks

43

[INNERVATION] Anterior compartment of leg

Deep peroneal nerve

44

[INNERVATION] Lateral compartment of leg

Superficial peroneal nerve

45

[INNERVATION] Posterior compartment of leg

Tibial nerve

46

Structures that pass through the tarsal tunnel

Tiny Dogs Are Not Hunters
1. Tibialis posterior
2. Flexor digitorum longus
3. Posterior tibial artery
4. Tibial nerve
5. Flexor hallucis longus
