functions of the hamstrings
flex the knee and extend the thigh
functions of the quadriceps
extend the knee
The extensor mechanism of the knee consists of
, quadriceps muscles and tendons
- patella
- patellar ligament
- tibial tubercle
- adjacent soft tissues
muscles that flex the knee
Biceps femoris
semimembranosus
semitendinosus
sartorius
gracilis
popliteus
gastrocnemius
muscles that extend the knee
rectus femoris
vastus lateralis
vastus medialis
vastus intermedius
extracapsular ligaments
patellar ligament
MCL
LCL
Oblique popliteal ligament (posterior)
Arcuate popliteal ligament (posterior)
Intraarticular ligaments
ACL
PCL
ACL functions
Prevent anterior sliding of tibia
- also secondary restraint to internal and valgus tibial rotations at full extension and
controls the screw home motion
PCL functions
prevents posterior sliding of the tibia
MCL
resteaint to valgus angulation
- secondary restraint to external tibial rotation
LCL
primary restraint to varus angulation
- secondary restraint to posterior translations
Ligaments roles during extension
collaterla vs cruciate
collateral ligaments are tensed, providing stability
- cruciate ligaments are relaxed
Ligament roles during flexion
collateral vs. cruciate
