Joints Flashcards
what are the intrinsic hip ligaments?
iliofemoral
ischialfemoral
pubofemoral
what is the shape and function of iliofemoral ligament
y shaped covers anterior aspect of the hip
-prevents overextension
pubofemoral ligament function
strengthens anterior and inferior part of capsule
helps prevent overabduction and overextension
ischiofemoral ligament function
strengthens joint posteriorly helps prevent overextension
5 extracapsular ligaments of knee joint
1) patellar ligament
2) fibular collateral ligament
3) tibial collaretal ligament (intrinsic)
4) oblique popliteal ligament (intrinsic)
5) arcuate popliteal ligament

Patellar retincaula
aponeurotic expansions of the vastus medialis and lateralis
support the articular capsule laterally and medially
1) medial and lateral longitudinal patellar retinaculum
2) medial and lateral transverse patellar retinaculum
fibular collateral ligament
popliteus tendon passes deep to it, seprates it from lateral meniscus
biceps femoris tendon split by fibular collateral ligament
medial or tibial collateral ligament
deep fibers attach to medial meniscus so often more damaged
tibial and fibular collateral ligaments
prevent damage to side of knee joint
taut when leg exteneded
slack during leg flexion
oblique popliteal ligament
expansion of semimembranousus tendon, strengthens capsule posteriorly
aarcuate popliteal ligament
y shaped, arches over popliteus and strengthens capsule posteriorly
ACL origin and insertion
origin, anterior part intercondylar eminence
inserts: medial side of lateral condyle of femor
PCL origin and insertion
posterior part intercondylar area of tibia
then attaches to lateral surface of medial condyle
functgion of anteromedial bundle
resists anterior tibial translation especially during flexion
function of posterolateral bundle
resist anterior tibial translation and tibial rotation in extension
