Sacrotuberous Ligament
O: anterior sacrum
I: Ischial tuberosity
EXTRINISIC SI
Prevents anterior tilt
Sacrospinous Ligament
O: Anterior sacrum
I: Ischial spine
EXTRINSIC SI
Prevents anterior tilt
Medial Collateral Ligament
O: Medial apicondyle of femur
I: Medial prox tibia
CAPSULAR: THICKENING of CAPSULE
Prevents Valgus forces
(effective in extension; high load when flexed)
Lateral Collateral Ligament
O: Lateral condyle of femur
I: Posterior fibular head (under biceps fem tendon)
EXTRINSIC
Prevents Varus force, ER, and Posterior glide
Oblique Popliteal Ligament
O: Lateral condyle femur
I: Medial condyle tibia
CAPSULAR
Prevents hyperextension, ER tibia, IR femur
(posterior reinforcement)
Arcuate Ligament
O: Lateral condyles of femur and tibia
I: head fibular
CAPSULAR
Limits hyperextension, varus force
(posterior reinforcement)
Anterior Cruciate Ligament
O: Medial aspect of lateral femoral condyle
I: Anterior intercondylar fossa
EXTRASYNOVIAL but in capsule
Prevents anterior tibial translation, IR tibia (Varus and Valgus)
Posterior Cruciate Ligament
O: Intercondylar surface of medial femoral condyle
I: Posterior intercondylar fossa (w/ meniscofemoral of menisci)
EXTRASYNOVIAL but in capsule
Prevens Posterior tibial translation (varus and valgus)
At risk when knee flexed 70-90 degrees
Ligament of Fibular Head (ant and post)
O: Lateral condyle of tibia
I: Ant/Post aspect of fibular head
SYNOV/GLIDING
Supports and seperation of prox tib-fib joint
Tibiofibular Ligament (Ant and Post)
O: Distal aspects of tibia
I: Distal Aspects of fibular
SYNDESMOSES
Support and seperation of distal tib-fib joint
Middle Tib-fib: Interosseus membrane
Tibia to fibula
SYNDESMOSES
Iliotibial Tract
O: Fascia of TFL and glute max
I: Lat tibial condyle
Reinforces lateral knee
assists ACL w/ tibi IR, posterior displacement
Varus stress
Coronary Ligament (Meniscus)
O: Menisci
I: tibia
Loose laterally with gap
Transverse Ligament (Meniscus)
O: anterior menisci
I: Other anterior menisci
Intercondylar Ligament (Meniscus)
O: Meniscal horns
I: Intercondylar eminence
Meniscofemoral Ligament (Meniscus)
O: Posterior horn of lateral menisci
I: Medial femoral condyle
Attatches posteriorly w/ PCL
