15:20
The most common serious knee ligament injury involves the ____.

The patellofemoral joint is an ____ joint
Arthrodial
Which of the following muscles externally rotates the knee?
Biceps femoris
Which of the following is NOT correct regarding the menisci of the knee?
Decrease stability
Which is NOT a factor implicated in the higher incidences of ACL injuries in females compared to males?
Decreased Q angle
The rectus femoris is more powerful in extending the knee when the hip is ____.
Extension
The rectus femoris can exert greater knee extension force, when the hip is in __ than when it is in ____.
Extension: Flexion
During weight-bearing exercise, greater forces are transmitted to the fibula than to the tibia
False
From a position of full extension, the knee can normally move through about 180 degrees of flexion.
False
In normal, healthy lower limbs, the hamstrings are stronger than the quadriceps.
False
Tears occurring within the innermost 1/3 of menisci are more likely to heal than tears within the outermost 1/3 of menisci.
False
The femoral condyles articulate with the fibular condyles during knee flexion.
False
The lateral collateral ligament is injured more frequently than other knee joint ligaments.
False
The patella serves as a pulley by improving the angle of pull of the hamstring muscles, creating a greater mechanical advantage during knee flexion.
False
The popliteus is a knee extensor
False
The popliteus originates on the posterior fibula.
False
The knee tibiofemoral joint is a _____ joint
Ginglymus
The pes anserinus is the common insertion of the _____.
Gracilis, Sartorius, and semitendinosus
Which of the following is NOT true of the quadriceps muscle group?
It serves to flex the knee
Which of the following is the most accurate test for detecting an ACL tear
Lachman
Which of the following is true regrading the medial collateral ligament?
Maintains medial stability by resisting valgus forces
Which of the following conditions involves apophysitis?
Osgood Schlatter's disease
The ___ provides the primary restraint for posterior movement of the tibia relative to the femur.
PCL
Which muscle is absent in some people?
Plantaris

Popliteus
Which of the following muscles internally rotates the knee?
Popliteus

Rectus femoris
Which muscle is shown in image (posterior, inner thigh)
Semitendinosus
Which of the following is correct regarding the patellofemoral joint?
The joint involves the interaction between the kneecap and the femoral condyles

True
The biceps femoris muscles inserts on the head of the fibula and lateral tibial condyle.
True
The close-packed position of the knee is full extension
True
The iliotibial tract of the tensor fasciae latae muscle inserts on Gerdy's tubercle.
True
The knee joint is the largest diarthrodial joint in the body.
True
The medial meniscus is larger than the lateral meniscus
True
The semimembranosus muscle is located posteromedially and internally rotates the knee.
True
What muscle is shown in image (anterior, inner thigh)
Vastus medialis
Which of the following is NOT one of the quadriceps muscles?
Vastus medius
Which are actions of gracilis?
knee flexion and internal rotation
All of the following are key bony landmarks for knee joint actions except the ___.
Superior and inferior patellar malleoli
The vastus medialis provides a ____ pull on the patella when contacting concentrically.
Superolateral
