AnatoKNEE
What does the MCL responsible for?
Valgus Stress
(especially with knee flexion)
What are the main functions of the menisci?
Load distribution and shock absorption
What would an increase in Q angle lead to ?
Genu Valgum
What are the three bones that comprise the hip and the official name
the ilium, ischium, and pubis
Inomonate
What is the typical angle of inclination of the femur in a normal adult?
125
Name a passive stabilizer of the knee other than the crucate/collateral ligaments?
ITB
Joint Capsule
True or False: the lateral meniscus is smaller, thinner, and less mobile than the medial meniscus
What is full knee extension?
Closed Packed position
Where is articular cartilage thicc in the hip?
Superior aspect of acetabulum because of load
As you increase angle of torsion, what happens to internal and external rotation?
ER decreases
IR increases
The structure that cushions the patella within the knee joint.
patellar tendon
How does the menisci help with joint stability?
Deepens articulating surfaces of the tibial plateau
What is genu valgum?
The condition where the anatomical axes of the tibia and femur form an angle greater than 195 degrees
What is the labrums function at the hip?
Deepen socket
Increase stability
What is the Closed-Pack Position of the Hip
Full extension, slight abduction, and slight
internal rotation
This structure is responsible for resisting anterior tibial translation and internal rotation, and its injury often involves hyperextension
Anterior Cruciate Ligament (ACL)
Describe how abnormalities in rolling mechanics can affect overall knee function
Impaired movement
Increase wear and tear
Instability
How does a clinician measure q angle?
SA: ASIS
AOR: midpoint of patella
MA: tibial tuberosity
True or False: As you move distally, the femur travels medially
TRUEEEEEEEEE
What affects can weak hip abductors do to gait?
Name them
Weak hip abductors can lead to a Trendelenburg gait
Gluteus Med/Min
The two joints that make up the knee
Describe how the alignment of the tibia and femur affects knee joint stability.
the patellofemoral and tibiofemoral joints
How does the menisci guide movement in the knee?
During flexion, the menisci moves posteriorly
During extension, the menisci moves anteriorly
What is the roll-and-glide mechanism?
The biomechanical term describing the movement pattern of the femur on the tibia during knee flexion and extension.
In how many planes and degrees of freedom does the hip joint move?
Name them
