Decreases stability
The rectus femoris is more powerful in extending the knee when the hip is in ___.
Extension
The lateral collateral ligament is more frequently injured than other knee joint ligaments.
False
The patella is classified as an "irregular" bone because it is imbedded in the patellar tendon.
False
The popliteus originates on the medial aspect of lateral femoral condlye.
False
The quadriceps muscles perform eccentric contractions during accelerating actions.
False
The semitendinosus is located laterally and internally rotates the knee.
False
The lateral collateral ligament originates on the lateral femoral condyle distally to popliteus origin and inserts on the fibular head.
False.
Which of the following is true regarding the medial collateral ligament?
Maintains medial stability by resisting valgus forces or preventing knee from being abducted
The only uniarticular knee flexor is the ____.
Popliteus
Which of the following is not true regarding the hamstring muscle group?
Provides static stability to the knee joint.
Which of the following is not true with respect to the synovial cavity?
Provides the knee with stability.
The tibial division of the sciatic nerve innervates all of the following muscles except?
Sartorius
Which of the following muscles internally rotates the knee?
Semimembranosus
Which of the following is not correct regarding the knee joint proper?
Sometimes referred to as trochoginglymus joint due to internal and external rotation occurring when in full extenison
Which of the following is not true regarding strength and endurance being essential for maintenance of patellofemoral stability?
Strength and flexibility are not often a problem with the muscles of the knee joint
Muscles that flex the knee include all of the following except?
Tensor fascia latae
All three of the vasti muscles of the quadriceps originate on proximal femur and insert on patellar superior pole.
True
Articular cartilage is located on the surfaces of both the femur and tibia.
True
As the knee joint approaches full extension the tibia must extremely rotate approximately 10 degrees to achieve proper alignment of the tibial and femoral condyles.
True
Tears in menisci can occur due both compression and shear forces during rotation while flexing or extending during quick directional changes in running.
True
The biceps femoris inserts primarily on the head of the fibula.
True
The fibula is not part of the ginglymus articulation of the knee joint.
True
The iliotibial tract of the tensor fasciac latae inser.ts on Gerdy's condoyle
True
The knee joint can extend to 180 degrees normally although some individuals can extend slightly further.
True
The knee joint is the largest joint in the body.
True
The lateral fibula serves as the attachment for knee joint structures but does not articular with the femur or patella.
True
The medial collateral ligament originates on the medial aspect of upper medial femoral condyle and inserts on medial tibial surface.
True
The patella serves as a pulley by improving the angle of pull with the result being a greater mechanical advantage for the quadriceps during knee extension.
True
The sartorius, gracilis, and semitendinosus all insert just below the medial condyle on upper anteromedial tibial surface.
True
The tibia bears the majority of the weight as compared to the fibula.
True
The vastus medialias provides a ____ pull on the patella when contracting concentrically.
?
Which of the following is not true regarding the rectus femoris, vastus medialis, vastus intermedius, vastus lateralis?
All are superficial and palpable except vastus medialis
In basketball and soccer injury to the ____ occurs much more commonly to females than to males.
Anterior cruciate ligament
The most common serious knee ligament involves the ____.
Anterior cruciate ligament
Which of the following is not considered to be one of the quadriceps muscle group?

All of the following are key bony landmarks of the knee joint except?
Gerdy's Condlye
The pes anserinus tendinous expansion is comprised from the ____.
Gracilis, sartorius, semitendinosus
The semimembranosus is located posteromedially and internally rotates the knee.
True
The Q angle is usually ___ or less for males and ___ or less for females.
15, 20`
The vastus lateralis providees a ____ pull on the patella when contracting concentrically.
?
The anterior and posterior cruciate ligaments are located on the outermost anterior and posterior surface of the knee joint.
False
The femoral condyles articulate with the fibular condyles during flexion of the knee.
False
The hamstring muscles function as a decelerator of the knee when decreasing speed to change direction and especially when landing from a jump.
False
The semimembranosus inserts anteromedially on the medial tibial condyle.
False.
