1
What is anterior and superior parts of the knee joint?
Quadriceps tendon and patellar tendon
2
What are the three separate articulations?
Femoropatellar and two femorotibial
3
What does not articulate with the knee joint?
Fibula
4
What are the capsule attachments anteriorly?
Fuses with quadriceps tendon, patella and ligamentum patellae
5
What are the capsule attachments posteriorly?
Encloses intercondylar fossa of femur; open posterior to lateral condyle of tibia for popliteus muscle
6
What covers the inner surface of the fat pads on either side of the patellar ligament?
Medial and lateral alar folds
7
What are synovial attachments?
Alar folds and Infrapatellar synovial fold
8
What are in communication with the synovial cavity of the knee joint?
Suprapatellar, Gastrocnemius, Semimembranosus and popliteus
9
What are the extracapsular ligaments?
Oblique Popliteal, Arcuate Popliteal and Medial & Lateral collateral
10
What are the intracapsular ligaments?
Anterior and posterior cruciate
11
What is the oblique popliteal ligament?
Expansion of Semimembranosus tendon which reinforces posterior capsule
12
What is the arcuate ligament?
Thickening of capsule over popliteus
13
What is the function of the arcuate ligament?
Strengthens posterolateral joint capsule
14
What is the medial collateral ligament?
Strong, flat thickening of capsule
15
What is the proximal attachment of the medial collateral ligament?
Medial epicondyle of femur
16
What is the distal attachment of the medial collateral ligament?
Medial condyle and superior medial surface of tibia
17
What do the deep fibres of the medial collateral ligament attach to?
Medial meniscus
18
What is the lateral collateral ligament like?
Strong and cord like
19
What is the proximal attachment of the lateral collateral ligament?
Lateral epicondyle of femur
20
What is the distal attachment of the lateral collateral ligament?
Lateral head of fibula
21
The tendon of biceps femoris is split into?
Two
22
What are taut in every joint position?
Cruciate ligaments
23
What do the cruciate ligaments do?
Maintain contact between femoral and tibial articular surfaces when knee is flexed
24
When do the cruciate ligaments wind around each other?
During medial rotation of the tibia limited to 10 degrees
25
What is the function of the posterior cruciate ligament?
Prevents the femur from sliding anteriorly on the tibia, particularly when the knee is flexed
26
What is the function of the anterior cruciate ligament?
Prevents the femur from sliding posteriorly on the tibia, preventing hypertension of the knee, and limits medial rotation of the femur when the foot is planted
27
What is the proximal attachment of the anterior cruciate ligament?
Anterior intercondylar area of tibia
28
What is the distal attachment of the anterior cruciate ligament?
Medial side of lateral condyle of femur
29
What degrees does the anterior cruciate ligament spiral through?
110 degrees between tibia and femur
