Flashcards in Knee Joint Deck (18):
1

What type of joint is the knee?

synovial, hinge

2

What are the movements of the knee?

flexion/extension with some gliding and rotation

3

Is the knee a weak or strong joint?

relatively weak because it's stability is primarily by ligaments and muscles

4

Name the 3 articulations of the knee

1. tibiofemoral joint: lateral femoral condyle with lateral tibial condyle

2. tibiofemoral joint: medial femoral condyle with medial tibial condyle

3. patellofemoral joint: patella and femur

5

This capsule of the knee does not form a closed fibrous sleeve around the joint. There are ligamentous expansions that replace it anteriorly and it is perforated posteriorly by the popliteal muscles.

articular capsule

6

3 anterior structures of the knee

1. quadriceps tendon
2. patella
3. patella ligament

7

What is the lateral expansion from the quadriceps tendon, patella, and patella ligament that extend to the femoral and tibial condyles.

patellar retinacula

8

What m. perforates the capsule posteriorly?

popliteus m.

9

What ligament is a thickening of the capsule arching over the exiting popliteus?

arcuate popliteal ligament

10

What runs parallel to the popliteus?

oblique popliteal ligament

11

Where does the oblique popliteal ligament extend from?

semimembranosus n.

12

Which ligament DOES NOT blend with the capsule?
1. medial tibial collateral ligament
2. lateral fibular collateral ligament

2. lateral fibular collateral ligament

13

What blends with the capsule laterally?

iliotibial tract

14

What lines the fibrous capsule, creating an envelope for the synovial fluid that bathes the tibiofemoral and patellofemoral articular surfaces?

synovial membrane

15

What structure is within the capsule but are NOT within the synovial membrane?

menisci

16

The OUTER or INNER surface of the synovial membrane attaches to the edges of the menisci. (select one, OUTER or INNER)

OUTER

17

What structure is created anteriorly to cruciate ligaments?

infrapatellar synovial folds

18

What is the large, upward extension of the synovial cavity, deep to quadriceps tendon?

suprapatellar bursa
