Knee Joint
The most poorly constructed joint in the
body. Femur round, tibia flat.
 Comprised of four bones.

Femur
 Tibia
 Fibula
 Patella

Femur

Medial and Lateral
Condyles- distal ends
of the femur.
Patella


Patella tendonattaches to the
anterior of the tibia.
Quadriceps tendonattaches the
quadriceps to the
patella.
Cruciate Ligaments



Major stabilizing
ligaments in the knee
Anterior Cruciate
Ligament (ACL)-prevents
the tibia from sliding out
in front of the femur
Injuries caused by
hyperflexion
Cruciate Ligaments


Posterior Cruciate
Ligament (PCL)-It
prevents the tibia
from sliding
backwards under the
femur.
Injuries usually
caused by
Hyperextension
Collateral Ligament


Medial Collateral
Ligament (MCL)connect the tibia and
the femur.
A force from the
lateral side could
cause a tear.
Collateral Ligament


Lateral Collateral
Ligament (LCL)connect the fibula to
the femur.
A force from the
medial side can
cause a tear of the
LCL
How are ligaments torn?


Medial collateral
ligament (MCL) is
injured from a
blow/force to the
outside of the leg.
Lateral collateral
ligaments are torn
blow/force to the
inside of the leg.
Cartilage


Articulate Cartilagecovers the moving
parts of the knee.
Chronic damage to
articulate cartilage
leads to arthritis.
Cartilage

Meniscus- half moon
shaped cartilage lying
between the knee
joint.
