Flashcards in 1. Knee exam Deck (23)
anterior cruciate ligament
Posterior cruciate ligament
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
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
Posterior drawer sign
With patient supine , bending knee at 90 degree angle , increased posterior gliding of tidia due to posterior cruciate ligament
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
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
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
anterior and posterior in anterior and posterior cruciate ligament refer to
sites f tibial attachment (superior surface )
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
Lateral collateral ligament injury - test
abnormal passive adduction
posterior cruciate ligament - test
posterior drawe sign
meniscal tear test
abnormal passive adduction --> injury of
Lateral collateral ligament
Lateral meniscal tear test
McMurray test with internal rotation
• 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
• 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
• Regarding the cruciate ligaments, the terms anterior and posterior refer to the sites of ____ (tibial/femoral/fibular) attachment.
• On physical exam, a patient has a positive anterior drawer sign. This indicates that what ligament was torn?
Anterior cruciate ligament
• A patient has knee pain. While supine, there is a "pop" elicited on external rotation of the knee. Where is the patient's injury?
• A patient has knee pain. While supine, there is a "pop" elicited on internal rotation of the knee. Where is the patient's injury?
• 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
