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.
