1

Tendon of the quadriceps muscles

Suspending the patella

2

Femur

Function: articulates only with the tibia

3

Weight bearing segment of the knee joint

Formed btwn the medial and lateral condyles of the femur and medial and lateral condyles of the tibia.

4

Patella

Suspened in the tendon of the quadriceps and is attached to the tibial tuberosity above
Below, by the the patellar ligament.

5

Menisci

Dense c-shaped fibrous tissues with the medial meniscus, being larger and firmly attached to the medial condyle, provide stability to the joint.

6

Collateral ligaments

Location: on each side,
Function: act to reinforce the joint capsul, help to provide strength to the knee joint

7

Proximal end of the medial (tibial) collateral ligament

Location: firmly attached to the medial epicondyle of the femur

8

Distal end of the medial (tibial) collateral ligament

Location: secured to the upper shaft of the tibia.

9

Medial collateral ligaments

Posterior fibers of this wide, triangular ligament are attached to the medial meniscus

10

Latera (Fibular) collateral ligament

Location: extends btwn the lateral epicondye of the femur and the head of the fibula.
Function: not attached to the lateral meniscus.

11

Anteriro tibiofibular ligament

Location: attached to the head of the fibula
Originates from the lateral condyle of the tibia.

12

Cruciate Ligaments

Paired
Location: crosses to connect the femur and tibia.
Inside the knee capsule and named because of their attachment to the tibia.

13

Anterior Cruciate ligament

ACL
Location: attached to the anterior surface of the tibia, in front of the tibial spine
Curves backward to reach the lateral condyle of the femur, behind the intercondylar notch
Function: limiting extension of the lateral femoral condyle.

14

Posterior cruciate ligament

PCL
Location: attached btwn the tibial condyles, on the posterior surface and passes forward to reach the medial condyle of the femur in front of the intercondylar notch.

15

Cruciate ligaments (Function)

serve to prevent displacement of the femur from the tibial plateau.

16

Interosseous Membrane

Function: bind the two leg bones together, help resist the downward displacement of the fibula, when muscles of the fibula contract.

17

Knee Injurises

Damage to these ligaments, severe blow to the lateral knee,
Medial meniscus, medial collateral ligament and anterior cruciate ligament are often torn at the same time.

18

Posteriro cruciate ligament tear

Knee is bent and force is applied from the anterior direction
