Compartments innervated by the inferior gluteal nerve
Gluteus maximus
Ligament that prevents lateral displacement (abduction) of the tibia under the femur
Tibial collateral ligament
Ligament that prevents medial displacement (abduction) of the tibia under the femur
Fibular collateral ligament
Estructures whitin the femoral triangle

Artery
Vein
Empty space (femoral canal)
Lymph nodes
3 most common injured structures at the knee
- Tibial collateral ligament
- Medial meniscus
- Anterior cruciate ligament
Signs of medial meniscus tear
Pain then the leg is medially rotated at the knee
