knee, patella, femur rad tech

The knee is formed by

Femoral condyles and tibial plateaus

The knee is classified as

Synovial, diarthrodial, hinge

type joint

The knee is protected by the

Protected by patella

the patella is a ______ bone and is located on the ______ surface of the _________

Sesamoid bone

– Located on anterior surface of

femur

The femur, tibia, fibula, and patella are held together by a

_________

complex group of ligaments.

These ligaments work together to provide stability for the knee joInt

-Posterior cruciate ligament (PCL)

– Anterior cruciate ligament (ACL)

– Tibial collateral ligament (TCL)

– Fibular collateral ligament (FCL)

the knee is stabilized and cushioned by

menisci

menisci lie on the ______

tibial plateaus

medial menisci and lateral menisci

The knee is made up of:

epicondyles

-condyles

-intercondylar fossa

Th epicondyles are on the _____

Distal end, designed as medial and lateral

The condyles are

– Expanded, palpable

distal ends

– Medial and lateral articulate with tibia to form knee joint

Intercondylar fossa

– Depression between

condyles on posterior

surface

The patella is the ______ sesmoid bone

largest, most consistent sesmoid bone in the body

The patella is on the ______, ______ side of the ______

Distal, anterior, femur

Where and when does the patella form

In the quadriceps femoris tendon at 3-5

The patella is

Triangular shaped,

• apex points towards knee

• Base is superior aspect

The Prox femur has a

• head

• Neck

• Greater trochanter

• Lesser trochanter

• 
  

The femur is classified as

Classified as a long bone

• Largest bone in the body

The head

• Proximal, rounded end

– Articulates with acetabulum of pelvis to form hip joint

The neck

Slender region just below head

Greater trochanter

Large prominent, palpable process at proximal end on lateral side

Lesser trochanter

Located medial and posterior surface

The distal femur has

• lateral condyles

• Medial condyles

• Lateral epicondyle

• Medial epicondyle

• Intercondylar fossa

• Polietal surface

• Adductor tubercle

Epicondyles

• Distal end, just above condyles

• Designated as medial and

lateral

condyles

• Expanded, palpable distal ends

• Medial and lateral articulate with tibia to form knee joint

Fabella

• The posterior area of the knee, between the condyles, contains a sesamoid bone in 3% to 5% of people. This sesamoid bone is called the Fabella

Intercondylar fossa

Deep depression on posterior surface between condyles

The triangular area superior to the intercondylar fossa on the posterior femur is the

trochlear groove, over which the popliteal blood vessels and nerves pass
