1

ACL

anterior cruciate ligament

2

PCL

Posterior cruciate ligament

3

Anterior drawer sign

With patient supine, bending knee at 90 degree angle , increased anterior of tibia due to anterior cruciate ligament injury ---> Lachman tst similar, but 30 angle

4

Knee exams - tests ?

1. Anterior drawer sign
2. Posterior drawer sign
3. Abnormal passive abduction
4. Abnormal passive adduction
5. McMurray test
6. Lschman sign

5

Posterior drawer sign

With patient supine , bending knee at 90 degree angle , increased posterior gliding of tidia due to posterior cruciate ligament

6

Abnormal passive abduction

With patient supine and knee either extended or at 30 degree angle, lateral ( varus) force --> medial space widening of tidia --> MCL inhury

7

Abnormal passive adduction

With patient supine and knee either extended or at 30 degree angle, medial ( varus) force --> lateral space widening of tidia --> LCL inhury

8

McMurray test

With the patient supine and knee internally and externally rotated during range of motion
- pain, pooping on external rotation --> medial meniscal tear
-pain, pooping on internal rotation --> lateral meniscal tear

9

anterior and posterior in anterior and posterior cruciate ligament refer to

sites f tibial attachment (superior surface )

10

ligaments of the knee

1. anterior cruciate ligament
2. posterior cruciate ligament
3. lateral meniscus
4. medial meniscus
5. Lateral collateral ligament
6. Medial collateral ligament

11

Lateral collateral ligament injury - test

abnormal passive adduction

12

posterior cruciate ligament - test

posterior drawe sign

13

meniscal tear test

McMurray test

14

abnormal passive adduction --> injury of

Lateral collateral ligament

15

Lateral meniscal tear test

McMurray test with internal rotation

16

• A supine man with his knees at a 90° angle has an increase in anterior tibial gliding without other knee findings. Injury location?

This is likely anterior cruciate ligament injury

17

• A supine man with his knees at a 90° angle has an increase in posterior tibial gliding without other knee findings. Injury location?

This is likely posterior cruciate ligament injury

18

• Regarding the cruciate ligaments, the terms anterior and posterior refer to the sites of ____ (tibial/femoral/fibular) attachment.

Tibial

19

• On physical exam, a patient has a positive anterior drawer sign. This indicates that what ligament was torn?

Anterior cruciate ligament

20

• A patient has knee pain. While supine, there is a "pop" elicited on external rotation of the knee. Where is the patient's injury?

Medial meniscus

21

• A patient has knee pain. While supine, there is a "pop" elicited on internal rotation of the knee. Where is the patient's injury?

Lateral meniscus

22

• A supine man with his knee extended has medial tibial space widening when a valgus force is applied. Site of injury?

Medial collateral ligament (valgus force is lateral

23

• A supine man, with his knee at a 30-degree angle, has lateral tibial space widening when a varus force is applied. Site of injury?

Lateral collateral ligament (varus force is medial)
