SUMMARY
TIP: mnemonic - LAMP: Lateral condyle to Anterior cruciate; Medial condyle to Posterior cruciate.
1. Named for their tibial origins. There is torsion of the ligaments.
2. ANTERIOR CRUCIATE LIGAMENT - arises from the anterior tibial plateau, in front of the tibial spine. It has 2 bundles: anteromedial & posterolateral. Attached to the lateral femoral condyle in the intercondylar notch. This is important in limiting extension & involved in the locking ('screw-home') mechanism.
3. POSTERIOR CRUCIATE LIGAMENT - arises from the posterior surface of the tibia. Attached to the medial femoral condyle in the intercondylar notch. The PCL is the only stabilizing factor in the weight-bearing flexed knee, hence the patient will have difficulty walking down hill.
