Attachments of fibrous capsule of knee
margins of the femoral condyles to the margins of the tibial condyles
Attachments of medial collateral ligament of the knee
medial epicondyle of the femur to the medial condyle & shaft of the tibia
Deep to sartorious and pes anserine
Function of MCL of the knee
resists valgus force, stabilizes medial aspect of the joint
Attachments of lateral collateral ligament of the knee
lateral epicondyle of the femur to the head of the fibula
Function of LCL in knee
resists varus force, stabilizes lateral aspect of the joint
Attachments of anterior cruciate ligament
medial part of the anterior intercondylar area of the tibia to the posterior part of the medial surface of the lateral condyle of the femur
Functions of the ACL
prevents posterior displacement of the femur on the tibia/anterior displacement of tibia on femur; prevents hyperextension of the knee and limits rotation of the tibia on the femur
Attachments of the posterior cruciate ligament
posterior intercondylar area of the tibia to the lateral surface of the medial condyle of the femur
Function of the PCL
prevents anterior displacement of the femur on the tibia/prevents posterior displacement of tibia on the femur
Attachments of medial meniscus
anterior and posterior regions of the intercondylar area of the tibia & fibrous capsule at the medial collateral ligament
Attachments of lateral meniscus
anterior & posterior regions of the intercondylar area of the tibia
Attachments of patellar ligament
apex of patella to the tibial tuberosity
Function of patellar ligament
resists knee flexion, serves as a component of extensor mechanism for quadriceps mm. to extend the tibia on the femur
Attachments of medial patellofemoral ligament
proximal 50% of medial patell to the medial epicondyle of the femur
Function of medial patellofemoral ligament
restrains against lateral patellar displacement
Attachments of talocrural fibrous capsule
borders of the articular surfaces of tibia & malleoli to the margins of the trochlear surface of the talus
Attachments of medial collateral ligament of ankle (deltoid)
medial malleolus to the talus, navicular, & sustentaculum tali of the calcaneous
Function of medial collateral ligament (deltoid) of ankle
stabilizes joint & resists forced eversion
Attachments of posterior talofibular ligament
malleolar fossa of the fibula to the lateral tubercle of the talus
Function of posterior talofibular ligament
resist talocrural inversion
Attachments of calcaneofibular ligament
tip of the lateral malleolus to the lateral surface of the calcaneous
Function of calcaneofibular ligament
resist calcaneal/subtalar inversion
Attachments of anterior talofibular ligament
anterior lateral malleolus of the fibula to the neck of the talus
Function of anterior talofibular ligament
resist talocrural inversion and resist anterior translation of the talus
Attachments of long plantar ligament
plantar surface of the calcaneous & cuboid to the plantar surface of the bases of the metatarsals
Attachments of short plantar ligament (plantar calcaneocuboid)
calcaneus to the plantar surface of the cuboid
Attachments of spring ligament (plantarcalcaneonavicular)
anterior margin of the sustentaculum tali to the plantar surface of navicular
Function of spring ligament
supports medial longitudinal arch of the foot
Glide that occurs with talus in mortise during ankle dorsiflexion
posterior glide
