describe the adductor canal + the structures that pass through it
passageway for structures moving b/t anterior thigh + posterior leg
-> fem artery, vein, saphenous nerve
list the borders of the adductor canal
anteromedial = sartorius
lateral = vastus medialis
posterior = adductor longus/magnus
what types of joints are the proximal and distal tibiofibular joints
proximal = plane synovial
distal = syndesmosis
4 ligaments of the tibiofibular joints
anterior inferior tibiofibular
posterior inferior tibiofibular
inferior transverse
interosseus lig
3 ligaments making up lateral collateral lig of ankle
attaching to talus:
- anterior TFL
- posterior TFL
attaching to calcaneus:
- calcaneofibular
4 ligaments making up medial collateral lig of ankle
- tibionavicular
- tibiocalcaneal
- posterior tibiotalar
- anterior tibiotalar
what is the pes anserine tendon
where gracilis, semitendinosus + sartorius join and insert to medial knee (tibial condyle)
what 3 things attach to the medial process of the calcaneus
abductor hallucis longus
flexor digitorum brevis
plantar apneurosis
what is the talar canal + tarsal sinus
space b/t calcaneal + talar sulci (b/t talus + calcaneus)
tarsal sinus = lateral wider portion of canal
2 ligaments attaching to talus neck
anterior tibiotalar
anterior talofibular
what ligament attaches to the medial tubercle of the talus

3 things inserting onto the navicular tuberosity
plantar + medial navicular ligs
tib posterior tendon
fibularis longus
o = lateral condyle of tibia, prox. 2/3rds of lateral fib surface, intermuscular septa
i = secured by superior peroneal retinaculum, inserts on lateral base of 1st metatarsal + medial cuneiform
a = eversion + plantarflexion
n = superficial fibular
ACL function
prevents anterior displacement of tibia on femur
PCL function
prevents posterior displacement of tibia on femur
Menisci function
stability, weight distribution + lubrication
MCL function
resists valgus stress, checks ER
LCL function
resists valgus stress, checks ER of tibia
Tensor fasciae latae
o = iliac crest
i = iliotibial tract (lateral condyle)
a = flex/abduct hip
n = superior gluteal
Iliotibial band
o = lateral aspect of iliac crest, lateral hip joint capsule, aponeurosis for glute max, TFL
i = iliotibial tract (lateral condyle)
a = all except ER
n = superior gluteal

forms roof of tarsal tunnel
location and function of long plantar ligament
calcaneus to base of metatarsals
-> forms longitudinal arch
location + function of spring ligament
sustentaculum tali of calcaneus to medial plantar surface of navicular
-> thick + wide / supports medial longitudinal arch
