Flashcards in Joints - Knee joint Deck (23):
1

The knee joint is the _______ and most _______ joint.

Largest and most complex

2

The knee joint primarily acts as a ____ joint. Meaning it is _______.

Hinge joint
uniaxial

3

Two _______ _____ occur within the joint cavity.

Fibrocartilage menisci.

4

The condyles of the _____ roll along the almost flat condyles of the _____.

femur
tibia

5

The knee joints performs what types of movements?

Flexion and extension

6

______ tendon runs through the ______ and inserts on the _____ ________.

Quadriceps
Patella
tibial tuberosity

7

In the knee joint, ______ prevents friction of the ______ on the _______ tendon.

Bursa
tibia
quadriceps

8

Two ________ ligaments called ______ ligaments are found within the knee capsule.
Cruciate means to _____.

Two intracapsular ligaments called cruciate ligaments are found within the knee capsule.
Cruciate means to cross.

9

The lateral ______ are on either side of the _______ ligaments.

Menisci
Cruciate

10

_______ floats into the quadriceps tendon.

Patella

11

The major ligaments of the knee joint become _____ when the knee is extended to prevent _________.

taut
hyperextension

12

What are the major ligaments of the knee joint?

Extracapsular ligaments.

13

Extracapsular ligaments, include what? What do they prevent?

Fibular collateral ligament (lateral)
Tibial collateral ligament (MCL) (medial)
Prevent medial/lateral movement of the leg.

14

The MCL is located on the ______.

tibia

15

The intracapsular ligaments are called the ________ ligaments.
They cross each other like an ___.
Each cruciate ligament runs from the _______ ____ to the _____ _____.

cruciate
X
proximal tibia
distal femur

16

The ACL or, ______ _____ _____ prevents ______ sliding of the _______.

Anterior cruciate ligament prevents anterior sliding of the tibia

17

The posterior cruciate ligament prevents _______ sliding of the _____ or _______ displacement of the ______.

forward sliding of the femur or posterior sliding of the tibia

18

Describe the stabilizing function of the cruciate ligaments?

Prevent anterior/posterior movement of the tibia with respect to the femur when not straight.
When straight, ligaments get tight to prevent hyperextension.

19

Lateral blows to the knee can tear what?

Tibial collateral and medial meniscus.
ACL
i.e. lateral blows affect the medial side

20

Recently, we found the ______-_____ ligament. Old surgeries would often break this.

Anterior-lateral ligament

21

How is an ACL fixed?

Take tendon from hamstring, thread it through to make new ACL.

22

Describe osteoarthritis.

Cartilage destroyed, bone on bone grinding, causes bone spurs, pieces of bone broken off with friction.

23

Why is the butterfly stance problematic?

Acetabulum hit by the head of the femur, get bone spurs.
Also slams the medial part of the knee joint.
