Question 1

What type of joint is the knee joint

Answer 1

Question 2

There are two articulations within the knee joint

Answer 2

Tibiofemoral joint

Patellofemoral joint

Question 3

Which femoral condyles are longer and curves laterally

Answer 3

Medial femoral condyle

Question 4

Femoral condyles are seperated by… (anteriorly and posteriorly)

Answer 4

Patella surface

Intercondylar fossa

Question 5

Central intercondylar regions is

Answer 5

The attachment side for menisci, ligament, and intercondylar eminence

Question 6

Cartilage is made up of

Answer 6

Proteoglycans

Question 7

Shape of medial meniscus

Answer 7

C shaped

Question 8

Shape of lateral meniscus

Answer 8

O shaped (mobile)

Question 9

Function of menisci contact area

Answer 9

Increases contact area, so the stress between articular surfaces is reduced.

Question 10

Knee capsule attachements

Answer 10

Anterior: margins of patella , patella ligaments, and medial and lateral patellar retinacular.
Posterior: above femoral condyles and below tibial plateau.

Question 11

Patella ligament is a

Answer 11

Capsular ligament

Question 12

Capsular ligament is

Answer 12

Thickening of capsule.

Question 13

Non-capsule is

Answer 13

Not attached to capsule, either intracapsular or extracapsular.

Question 14

Posterior capsular ligaments

Answer 14

Arcuate Popliteal Ligament

Oblique Popliteal Ligament

Question 15

Lateral femoral collateral ligaments attachment

Answer 15

non-capsular extracapsular

Lateral femoral epicondyle to the head of fibula

Question 16

Lateral femoral collateral ligament prevents

Answer 16

Excessive movement of tibia in the medial direction (varus)

Question 17

Medial tibial collateral ligament attachment

Answer 17

capsular and noncapsular extracapsular.

Medial femoral epicondyle to medial condyle and medial meniscus.

Question 18

Medial tibial condyle prevents

Answer 18

Excessive movement to tibia in lateral direction (valgus)

Question 19

Anterior Cruciate ligament attachment

Answer 19

Non-capsular intracapsular

Anterior intercondylar area of tibia to lateral femoral condyle.

Question 20

ACL prevents

Answer 20

Excessive tibia movement forward.

Question 21

PCL attachment

Answer 21

Noncapsular intracapsular

Posterior intercondylar area of tibia to medial femoral condyle.

Question 22

PCL prevents

Answer 22

Excessive posterior displacement of tibia

Question 23

Tibiofemoral joint movement

Answer 23

Flexion and extension

When knee is flexed there is slight medial and lateral rotation.

Question 24

Weight non-bearing of knee flexion and extension

Answer 24

Tibia rolling and gliding on the fixed femur.

Question 25

Weight bearing of knee during flexion and extension

Answer 25

Femur rolling and gliding on a fixed tibia.

Question 26

Knee flexion degree

Answer 26

120 to 135

Question 27

Knee extension

Answer 27

0 to 10

Question 28

In non weight bearing extension from flexion tibia moving on femur

Answer 28

The tibia laterally rotates as knee joint approaches full extension. Conjunction rotation.
