How does the anterior cruciate ligament (ACL) attach/run?
|
From anterior intercondylar part of tibia, to lateral posterior of femur.
The ACL runs Posteriorly to attach to the EXternal femoral condyle (APEX). |
|
|
How does the posterior cruciate ligament (PCL) attach/run?
|
From posterior intercondylar part of tibia, to medial anterior of femur.
The PCL runs Anteriorly to attach to the INternal femoral condyle (PAIN). |
|
|
What does the lateral meniscus look like?
|
Very close to a complete circle.
|
|
|
What does the medial meniscus look like?
|
Very close to a half circle.
|
|
|
Which meniscus is attached to the collateral ligament?
|
The medial meniscus is directly attached to the tibial/medial collateral ligament.
|
|
|
Which three structures of the knee are commonly injured together?
|
1. medial collateral ligament
2. medial meniscus 3. ACL |
|
|
Does the joint capsule (synovium) encompass the ACL/PCL?
|
No

What is the role of the ACL?
|
prevents anterior displacement of the tibia (at 90 degrees)
|
|
|
What is the role of the PCL?
|
prevents posterior displacement of the tibia (at 90 degrees)

|
|
When the knee is straight, which ligament is taught?
|
ACL

What type of cartilage are the menisci?
|
fibrocartilage
|
|
|
What is the role of the menisci?
|
act as shock absorbers
|
|
|
What is the test for the ACL?
|
anterior drawer test
Lachman's test (Pivot shift test) |
|
|
What is the test for the PCL?
|
posterior drawer test
tibial sag sign |
|
|
What is the test for the menisci?
|
McMurray's test
|
|
|
What is the basic principle behind McMurray's test?
|
Open the joint on the medial side, then close the medial side while getting the femur to ride all along the meniscus feeling for a tear.
(opposite for the lateral meniscus) |
