Term
|
Definition
tibia articulates with femur
Condylar hinge joint - uniaxial joint
Movement: flexion & extension
Flexion of knee = femur slides forward
Extension of knee = femur slides backward
Largest joint in body - no bone stability
supported and maintained by ligaments and muscles
relies on soft tissues
most frequently damaged joint in body |
|
|
Term
|
Definition
Patella articulates with femur - patella joint
Gliding synovial joint - nonaxial
Patella moves up with extension, down with flexion due to the pull of the quadriceps
Posterior surface of patella covered with hyaline cartilage=smooth becomes rough and uneven when patella doesn't slide correctly in trochlear groove |
