Flashcards in Knee Region Deck (10):
0

Articulation of medial & lateral condyles of femur with the medial & lateral condyles of the tibia

Knee (femorotibial) joint

1

Struck to elicit the knee jerk reflex

The reflex is blocked by damage to the femoral nerve or spinal cord segments L2-4

Patellar ligament

2

From medial epicondyle of the femur to the tibial shaft

Abduction of the knee joint

Tearing causes abnormal passive abduction of extended leg

Medial (tibial) collateral ligament

3

From lateral epicondyle of the femur to the head of fibula

Adduction of the knee joint

Tearing causes abnormal passive adduction of extended leg

Lateral (fibular) collateral ligament

4

From anterior aspect of the tibia to the lateral condyle of femur

Prevents anterior movement of the tibia in reference to the femur

If torn --> abnormal passive anterior displacement of the tibia (anterior drawer sign)

Stretched by hyperextension injury at the knee joint

Anterior cruciate ligament

5

From posterior aspect of tibia to medial condyle of the femur

Prevents posterior movement of the tibia

If torn --> abnormal passive posterior displacement of the tibia (posterior drawer sign)

Stretched by hyperextension injury at the knee joint

Posterior cruciate ligament

6

C-shaped fibrocartilage attached to the medial collateral ligament

Easily torn because not very mobile

Medial meniscus

7

O-shaped fibrocartilage

Lateral meniscus

8

Related to the popliteal fossa which contains the tibial nerve, common peroneal nerve, popliteal artery & vein, & small saphenous vein

Knee region

9

Violent blow on the lateral side of the knee (football clipping) --> causes abduction & lateral leading to tearing of the ff:
- anterior cruciate ligament
- medial collateral ligament (excessive abduction of knee joint)
- medial meniscus

Terrible triad of Donoghue
