All of the following are key bony landmarks for knee joint actions except:

• Intercondylar eminence

• Posteromedial surface of the medial tibial condyle

• Upper anterior medial surface of the tibia just below the condyle

• Upper posterior medial surface of tibia

a

Which of the following is not correct regarding the knee joint proper?

• Also referred to as the tibiofemoral joint

• Classified as a ginglymus joint

• Considered by some authorities to be a condyloid-type joint

• Sometimes referred to as trochoginglymus joint due to internal and external rotation occurring when in full extension

d

Which of the following is correct regarding the patellofemoral joint?

• It is relatively uncommon for the joint to be injured.

• Part of the posterior patella is superior to the trochlea groove when the knee is in full extension.

• The patella hinges on the femoral condyles.

• The joint lacks ligamentous support.

b

Which of the following is not correct regarding menisci in the knee joint?

• The lateral meniscus is larger in circumference than the medial.

• They are both attached to the tibia.

• They providing a cushioning effect the between bones.

• They serve to deepen the concavity of the tibial plateus.

a

Which of the following is true regarding the medial collateral ligament?

• Maintains medial stability by resisting valgus forces or preventing tibia from being abducted

• Maintains medial stability by resisting valgus forces or preventing tibia from being adducted

• Maintains medial stability by resisting varus forces or preventing tibia from being abducted

• Maintains medial stability by resisting varus forces or preventing tibia from being adducted

a

Which of the following is not true with respect to the synovial cavity?

• Considered to be the "capsule of the knee"

• Lies under patella and between surfaces of tibia & femur

• Provides the knee with stability

• Supplies knee with synovial fluid

c

Which of the following is not true regarding the bursae of the knee?

• Bursae absorb shock and/or reduce friction

• Bursae are composed mainly of fatty tissue

• Some bursae are connected to synovial cavity

• There are more than 10 bursae in and around knee

b

Which of the following is not considered to be one of the quadriceps muscle group?

• Rectus femoris

• Vastus intermedius

• Vastus lateralis

• Vastus medius

d

Which of the following is not true regarding the quadriceps muscle group?

• Consists of 4 separate muscles

• Located in anterior compartment of the thigh

• Serve to extend the knee

• They all extend the knee and flex the hip when contracting concentrically

d

Which of the following is not true regarding the hamstring muscle group?

• Consists of 3 separate muscles

• Located in posterior compartment of thigh

• Provides static stability to the knee joint

• Responsible for knee flexion

c

Which of the following muscles is important in providing dynamic medial stability to the knee joint because of the manner in which it crosses the joint and is also responsible for internal rotation of the knee?

• The biceps femoris muscle

• The gluteus maximus muscle

• The gracilis muscle

• The semitendinosus muscle

d

The femoral nerve innervates all of the following muscles except:

• Biceps femoris

• Rectus femoris

• Vastus lateralis

• Vastus intermedius

a

The tibial division of the sciatic nerve innervates all of the following muscles except:

• Biceps femoris

• Sartorius

• Semimembranosus

• Semitendinosus

b

Which of the following is not true regarding the rectus femoris, vastus medialis, vastus intermedius, vastus lateralis?

• All attach to the patella then to tibial tuberosity via patellar tendon

• All are superficial and palpable except vastus medialis

• Generally desired to be 25% to 33% stronger than hamstring group

• Power may be measured by the vertical jump test

b

Which of the following is not true regarding strength and endurance being essential for maintenance of patellofemoral stability?

• Functional weight-bearing activities such as step-ups or squats are particularly useful for strengthening and endurance.

• Patellofemoral stability may be developed by resisted knee extension activities from a seated position.

• Quads are particularly prone to atrophy when injuries occur.

• Strength and flexibility are not often a problem with the muscles of the knee joint.
