Semimembranosus
Which of the following represents the truest agonistic relationship for the knee?

Anterior cruciate ligament
The rectus femoris is more powerful in extending the knee when the hip is in _______.
Extension
The knee joint can extend to 180 degrees normally although some individuals can extend slightly further.
True
The only uniarticular knee flexor is the _________.
Popliteus
The Q angle is usually ______ or less for males and _____ or less for females.
15; 20
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
The most common serious knee ligament injury involves the __________.
Anterior cruciate ligament
Which of the following is not true regarding the bursae of the knee?
Bursae are composed mainly of fatty tissue
As the knee approaches full extension the tibia must internally rotate approximately 10 degrees to achieve proper alignment of the tibial and femoral condyles.
False
The anterior and posterior cruciate ligaments are located on the outermost anterior and posterior surfaces 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 lateral collateral ligament originates on the lateral femoral condyle distally to the popliteus muscle origin and inserts on the fibular head.
False
The lateral cruciate 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 muscle originates on the medial aspect of the lateral femoral condyle and assists with knee internal rotation.
False
The semimembranosus muscle inserts anteromedially on the medial tibial condyle and assists with knee internal rotation.
False
All of the following are key bony landmarks for knee joint actions except:
Gerdy's tubercle
Which of the following is true regarding the medial collateral ligament?
Maintains medial stability by resisting valgus forces or preventing tibia from being abducted
Which of the following is correct regarding the patellofemoral joint?
Part of the posterior patella is superior to the trochlea groove when the knee is in full extension
Which of the following is not true with respect to the synovial cavity?
Provides the knee with stability
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 extension
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
The vastus lateralis provides a(n) _______ pull on the patella when contracting concentrically.
Superolateral
The vastus medialis provides a(n) ______ pull on the patella when contracting contentrically.
Superomedial
Which of the following is not correct regarding menisci in the knee joint?
The lateral meniscus is larger in circumference than the medial
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 semimembranosus muscle
Which of the following is not true regardi8ng the quadriceps muscle group?
They all extend the knee and flex the hip when contracting concentrically
All three of the vasti muscle of the quadriceps originate on the proximal femur and insert on the patellar superior pole.
True
Tears in menisci can occur due to both compression and shear forces during rotation while flexing or extending during quick directional changes in running.
True
The biceps femoris muscle inserts primarily on the head of the fibula and assists with knee external rotation.
True
The iliotibial tract of the tensor fasciae latae muscle inserts on the Gerdy's tubercle.
True
The knee joint is the largest joint in the body.
True
The lateral fibula serves as the attachment for the knee joint structures but does not articulate with the femur or the 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 quadriceps muscles perform eccentric contraction before concentric contractions in explosive jumping.
True
The sartorius, gracilis, and semitendinosus muscles all insert just below the medial condyle on the upper anteromedial tibial surface and assists with knee internal rotation.
True
The tibia bears the majority of the weight as compared to the fibula.
True
