Kinesiology: Knee

Front 1

What are the two joints in the knee?

Back 1

Patellofemoral joint
Tibiofemoral joint

Front 2

What is the purpose of the fibula?
a. maintains alignment of the knee
b. transfers weight across knee joint down to ankle

Back 2

a. maintains alignment of knee

Front 3

What is the purpose of the tibia?
a. maintains alignment of the knee
b. transfers weight across knee joint down to ankle

Back 3

b. transfers weight across knee joint down to ankle

Front 4

What is the normal angle of knee joint alignment?

Back 4

170-175 degrees

Front 5

What occurs when there is coxa vara at the hip joint?

Back 5

genu valgum

Front 6

When there is coxa valga at the hip joint what occurs at the knee?

Back 6

genu varum

Front 7

Name some complications of the knee joint.

Back 7

1. Vastus lateralis pulls the patella laterally
2. Excessive pronation/eversion
3. Vastus Medialis Oblique (VMO)

Front 8

What occurs in the unhappy triad that occurs because of sublaxation during a meniscal tear?

Back 8

tear of medial meniscus, MCL and ACL

Front 9

Are medial or lateral meniscus tears more prevalent?

Back 9

medial

Front 10

What are the treatment options for meniscus tears?

Back 10

If tear occurs on peripheral meniscus it is vascular and can heal on its own.
If tear occurs on the inside of the meniscus, a partial menisectomy is recommended. Sometimes complete menisectomies are used but it leads to osteoarthritis of the knee.

Front 11

Why are medial meniscus tears more common than lateral meniscus tears?

Back 11

They commonly occur when the foot is planted during axial rotation. The medial meniscus attaches to capsule of the joint rather than the MCL

Front 12

What are the menisci made of? And what are they the attachment point for? What are their purposes?

Back 12

fibrocartilage
quads and hamstrings
reduce and absorb compressive forces

Front 13

How many bursa packs are there in the knee? Where does the biggest fat pad occur?

Back 13

14
underneath the patella
