what’s the function of the tibia?
weight bearing bone of the lower leg
osgood Schlatter disease
- a condition where the tibial tuberosity separates from the body of the tibia
- occur in younger people
whats the function of the patella?
serves to protect the anterior aspect of the knee joint
what 2 ligaments does the knee joint rely on for stability?
depends on the posterior collateral ligament (PCL) and the anterior collateral ligament (ACL) for stability
collateral ligament
- strong bonds on the side of the knee
- prevents adduction and abduction movements in the knee
cruciate ligament
- strong cords that cross each other
- stabilize the knee by preventing anterior and posterior movement
true or false: the proximal fibula is NOT part of the knee joint
true
the border of the tibia is also known as the-
shin
when does the patella become loose/movable?
when the leg extends
patellar ligament
- maintains the integrity of the knee
infrapatellar fat pad
- protect the anterior aspect of the knee joint
bursa

true or false: the articular cavity of the knee is the largest in the body
true
true or false: the synovial joint enclosed in an articular capsule/bursa
true
define menisci
- articular disk
- crescent shaped fibrocartilage disk
whats the purpose of the menisci
- they act as shock absorbers to reduce some of the direct impact and stress that occurs at the knee joint
what does the menisci produce
they produce synovial fluid, lubricating the ends of the femur and tibia
how does knee trauma occur?
- happen as a result of sports such as snowboarding, skiing, football, or basketball
patellar surface
where the patella moves
true or false: the patella bone is the largest sesamoid bone
true
what is PCL
Posterior cruciate Ligament
what is ACL
Anterior cruciate Ligament
what is LCL
Fibular (Lateral) collateral ligament
what is MCL
Tibial (Medial) collateral ligament
