Intertrochanteric line
Which tibial condyle has a facet for articulation with the head of the fibula?
Lateral
The distal end (Close to the foot) of the tibia is a large club shape process called
Medial Malleolus
Above the femoral condyle's is called
Medial epicondyles lateral epicondyles
From the intercondylar eminence goes to 2 peaklike processes called
Medial intercondylar tubercles lateral intercondylar tubercles
When the tibial tuberosity ligament becomes detached it causes
Osgood Schlatter's disease
The incomplete separation or avulsion of the tibial tuberosity is known as:
Osgood-Schlatter disease
Lucent lesion in the metaphysis, usually at the distal femur
Osteoclastoma (giant cell tumor)
Shallow, triangular area on the anterior surface between the condyles
Patellar surface
The femoral condyles are separated anteriorly by
Patellar surface (shallow triangular depression)
Where is the tibial tuberosity?
The anterior surface of the tibia, just inferior from the condyles
The proximal end of the fibula is known as
The head
Tibial lateral condyle has a facet that articulate with
The head of the fibula
The patella is
The largest sesamoid bone
The anterior proximal surface of the tibia has a prominent process known as
Tibial tuberosity where tendons are attached
Why are all these bones composed together?
To carry the body in an upright position with minimal amount of stress
The patella is _____ in shape and located at the _____ _______ surface of the femur.
Triangular Distal anterior
What makes up the knee joint?
femur, tibia, fibula, patella
The small depression in the center of the femoral head is known as
fovea capitis
What does the patella protect?
knee joint
The kneecap is called
patella
Two bones of the leg?
tibia and fibula
Which structure does the head of the femur articulate?
Acetabulum
The proximal femur has a round head that articulates with
Acetabulum of the pelvis
Conical projection at the head/proximal end of the fibula
Apex
The medial formoral condyle is called
Adductor tubercle
distal tibiofibular joint
Amphiarthroses/slightly movable
The body of the femur is convex _______ and slants ______ 5 to 15°
Anteriorly medially
The lateroposterior aspect of the head on the fibula is
Apex or styloid process
Popiteal surface is where
Blood vessels and nerves pass
The knee joint is the most
Complex joint
The anterior surface of the tibial body is called
Crest/shin
proximal tibiofibular joint, patella femoral
Diarthoses/gliding
Knee joint Femorotibial
Diarthoses/hinge
FCL (lateral)
Fibular collateral ligament
The lateral surface of the distal end of the tibia is a triangular surface for articulation with the fibula called
Fibular notch
The apex is located
Inferiorly
In between the tibial plateaus is a sharp projection called
Intercondyle Eminence or tibial spines
The bigger Ridge connecting the trochanters posteriorly is
Intertrochanteric crest
The knee joint contains two fibrocartilage disc that sit on top of the tibial plateaus called
Lateral meniscus Medial meniscus (articulates w/femoral condyles)
Fibula is located on ______ ______.
Lateral side
Tibia and Fibia is referred to as
Leg or lower leg
Femur is the
Longest, strongest, heaviest bone
The proximal end I f the tibia closer to the hip has two condyles on it called
Medial condyle lateral condyle
The distal femur (towards the feet) has two large eminence called
Medial condyle's and lateral condyle's
________ is the triangular area superior/above the intercondylar fossa
Popliteal surface
What do the menisci do?
Provide stability and act as shock absorbers
The ligaments in the knee joint do what?
Provide stability for the joint
The base is located
Superiorly
Femur is referred to as
Thigh or upper leg
TCL (medial)
Tibial collateral ligament
The superior surface of the tibia condyles are smooth flat facets for articulation with the femur called
Tibial plateaus
ACL
anterior cruciate ligament
hip joint
diarthroses/ball and socket
Posteriorly, the femoral condyles are separated by a deep depression called the:
intercondylar fossa
PCL
posterior cruciate ligament
