1

Bones

Femur
Tibia
Fibula
Patella

2

Gerdy's Tubercle

The site of insertion of the iliotibial tract on the tibia. Some of the fibers of the biceps femoris tendon may also insert on this tubercle.

3

Pes Anserine (Goose Foot)

The common insertion of the gracilis, sartorius and semitendinosus.

4

Pes Anserine Bursa

This bursa is located between the tibia and the Pes Anserine.

5

Ligaments of the Knee

Medial Collateral Ligament
Lateral Collateral Ligament
Anterior Cruciate Ligament
Posterior Cruciate Ligament

6

Patellofemoral JOint

Quadriceps Tedon
Patellar Tendon
Medial Retinaculum
Lateral Retinaculum
Medial Patellofemoral Ligament
Lateral Patellofemoral Ligament

7

Q-Angle

Quadriceps Angle:
ASIS to midpoint of the patella
Midpoint of the patella to the Tibal Tubercle

Normal is 10-12* for males
Normal is 15* for females

8

Popliteus

Functions to unlock the knee by externally Rotating the femur on the tibia during the initial portion of knee flexion.

9

Screw Holme Mechanism

Look Up

10

IT Band

Proximal Attachment - Along the anterior part of the external lip of the iliac crest and outer surface of the anterior iliac spine.

Distal Attachment - inserts into the iliotibial band (or tract) at the junction of the proxmial and middle of the thigh

The ITB continues distally inserting into Gerdy's Tubercle on the tibia

11

Menisci

The menisci are semi-lunar shaped fibrocartilage.

Functionally:
Shock absorption
Dissipation of force
Improve joint lubrication
Enhance joint nourishment
Increase the congruency of the joint surfaces and improve weight distribution.

12

Knee Bursa

Suprapatellar Bursa
Subcutaneous Prepatellar Bursa
Subcutaneous Infrapatellar Bursa
Bursa under the lateral head of the gastroc

13

Plica

Synovial folds of tissue

14

Synovial Joint

and all the crap we talked about in class, intraarticular blah blah blah

15

Extracapsular

Situated outside of the capsule

16

Intracapsular

Situated or occuring inside/within the capsule

17

Intra-articular

Inside the joint

18

Types of Swelling

Immediate Swelling = Intra-articular extracapsular (ACL and PCL)

12-24 Hours after injury = Intracapsular and intra-articular (menisci)

24-48 Hours after injury = Etracapsular (MCL and LCL)
