Knee/Leg Flashcards
name the articulations of the knee joint and what types of joints they are
medial and lateral femorotibial joints - condyloid (hinge) joints
patellofemoral - sellar (gliding) joint
ACL function
primary restraint to anterior tibia translation
secondary restraint to varus (in extension) and IR
PCL function
primary restraint to posterior tibial translation
secondary restraint to varus, valgus, ER
where does the iliotibial band insert
- Gerdys tubercle
- patella and patellar tendon
- supracondylar tubercle
primary restraint to varus stress and also resists ER
lateral collateral ligament
primary static restraint to ER
popliteofibular ligament
primary restraint to valgus force
superficial MCL
primary static stabilizer against patella lateralization
medial patellofemoral ligament
what provides sensory to medial leg?
femoral n/saphenous
what provides sensory to lateral leg?
peronal n (L5)
- proximal lateral: lateral sural
- distal lateral: superficial branch
what provides sensory to proximal posterolateral leg?
tibial nerve - medial sural
what provides sensory to distal posterolateral leg?
sural n
what nerve root does patellar reflex test?
L4
