Term
Movements of the knee joint
Definition
flexion
extension
inward rotation (flexed)
outward rotation (flexed)
Term
Anterior muscles of knee joint
Definition
Rectus femoris
Vastus lateralis
Vastus Medialis
Vastus Intermedius
Term
Posterior muscles of knee joint
Definition
Biceps femoris
Semimembranosus
Semitendinosus
Sartorius
Gracilis
Popliteus
Gastrocnemius
Term
Knee Flexion Muscles
Definition
Biceps Femoris
Semimembranosus
Semitendinosus
Sartorius
Gracilis (early flexion)
(popliteus)
(Gastrocnemius)
Term
Knee Extensions Muscles
Definition
Rectus femoris
Vastus lateralis
Vastus medialis
Vastus Intermedius
Term
Knee outward/inward rotation during flexion
Definition
Outward: Biceps femoris (non weight bearing)
Inward: Semimembranosus, semitendinosus, popliteus
Term
Posterior Cruciate Ligament of the knee
Definition
Stops tibia from sliding backwards
Term
Anterior Cruciate Ligament of the knee
Definition
stops tibia from sliding backwards
Term
Ligaments of the knee
Definition
Lateral collateral ligament
Medial collateral ligament
ACL
PCL
Transverse ligament
Oblique popliteal ligament
Patellar ligament
Term
Lateral Collateral Ligament
Definition
attatched at femur and fibula
Term
Medial collateral ligament
Definition
attached at condyle of femur to tibia and medial meniscus
Term
Menisci
Definition
Thick outer border, thin inner border
Term
Transverse Ligament
Definition
Lateral meniscus to medial meniscus
Term
Patellar ligament
Definition
Connects patella with tuberosity of tibia
Patella increases angle of pull which makes quads more effective in knee extension
Term
Q angle
Definition
Anterior superior ilia spine to patella.
Tibial tuberosity to patella
Makes angle
Medial condyle is longer b/c of femoral angle
