- medial cutaneous
- intermediate/anterior cutaneous
- lateral femoral cutaneous
- superficial branch of obturator
- posterior cutaneous

STUDY DERMATOMES
Great saphenous vein drains…
dorsal venous arch
Small saphenous vein drains into…
popliteal vein
Muscles of anterior thigh
- sartorius
- iliacus
- psoas major
- pectineus
- quads
FEMORAL ARTERY
FEMORAL NERVE
Muscles of medial thigh
- gracilis
- adductor longus
- adductor brevis
- adductor magnus
- obturator externus
OBTURATOR NERVE (ANTERIOR)
MEDIAL CIRCUMFLEX ARTERY
Muscles of posterior thigh
- biceps femoris
- semitendinosus
- semimembranosus
- adductor magnus
TIBIAL PORTION OF SCIATIC NERVE
DEEP FEMORAL ARTERY
Femoral triangle borders
Superiorly - inguinal ligament
Medially - adductor longus
Laterally - sartorius
Contents passing through femoral triangle, from lateral to medial
- femoral Nerve and branches
- femoral Artery and vein
- deep inguinal lymph nodes
- femoral canal with femoral ring
Adductor canal contents
- femoral artery and vein
- deep lymphatic vessels
- saphenous nerve
- nerve to vastus medialis
Knee joint is a ______ joint
synovial condylar joint (modified hinge)
Patella on patellar surface of femur is a ________ joint
gliding
Knee joint is innervated by nerves that cross the knee joint, called…
- femoral
- obturator
- sciatic nerves
Movements of knee
- flexion (with 25° medial rotation)
- extension (with 25° lateral rotation)
The patella is thought to __________ the pull of the quadriceps
increase
Fibrous capsule is thick, but deficient anteriorly. To make up for it….
it’s covered by the fused tendons of the quadriceps and its expansion
Articularis genu…
pulls fibrous capsule out of the joint upon extension to prevent injury
The synovial membrane lines the fibrous capsule. It does/does not cover the articular surfaces?
DOES NOT
Of the 16 or so bursar around the knee, what are a 4 examples?
prepatellar, superficial infrapatellar, suprapatellar, and deep infrapatellar
Extracapsular ligaments of knee
- ligamentum patellae (continuation of quad tendon)
- tibial collateral (MCL; attaches to medial meniscus)
- fibular collateral (LCL; covered by tendon of biceps femoris)
- oblique popliteal (extension of semimembranosus)
- arcuate popliteal (Y-shaped)
How to test ACL/PCL/MCL/LCL injury?
“(direction of possible injury) Drawer Test”
Eg. “Anterior Drawer Test” tests ACL injury
ACL and PCL are most relaxed in…
30° of flexion
MCL and LCL are relaxed in…
flexion
Medial meniscus
- Oval
- attaches to transverse genicular ligament, fibrous capsule, and MCL
Lateral meniscus
- Round
- attaches to transverse genicular ligament and tendon of popliteus
