what bones create the ankle joint -talocural
tibia, fibula, talus
knee joint
what 3 stabilities is the knee joint made for?
- bony stability
- muscualr stability
- ligamentous stability
what are the 3 bones participating in the knee?
- femur
- tibia
- patella
only 2 of these are bones technically
how many points of articulation are in the knee? what are they?
3 points of articulation
- femur and tibia (medial/lateral) condyles
- femur (patellar surface)
- patella (medial/lateral articular surfaces)
osteology
what shape is the patella?
what kind of bone is the patella?
what is the patella an important insertion point for?
- relatively heart shaped
- sesamoid bone
- importatn insertion for ligaments
soft tissue also supports the knee - what 2 types of ligaments?
- intra-articular
- extra-capsular
what is the primary action of patella?
flexion/extension
how many facets of patella? how many are paired? how many are singular?
7 facets (relative to action)
- 6 paired facets (medial/lateral)
- 1 unpaired (mostly medial)
Where is the Q angle drawn between?
drawn between os coxa (ASIS) and mid patella
tibia (tibial tuberosity) and mid patella
What are the three major joints of the lower limb?
Knee, Hip, Ankle (Talocrural)
The knee involves the patella, unlike the upper limb joints.
