Which of the following is NOT true of the knee joint?
A) The knee is a modified hinge joint.
B) The knee contains a lateral meniscus and a medial meniscus.
C) It contains a condylar joint between the patellar surface of the femur and the patella.
D) The ACL (anterior cruciate ligament) is positioned so that it helps prevent hyperextension of the knee.
E) All of these are true of the knee joint.
ACL
The anterior cruciate ligament, a key ligament that stabilizes the knee joint.
Modified Hinge Joint
A type of synovial joint that allows predominantly bending motion like a hinge but with limited rotational movement for added flexibility.
Condylar Joint
A type of synovial joint that allows movement but is constrained to one axis; for example, the joint between the skull and the atlas (first cervical vertebra).

Final Answer :
C
Explanation :
The knee joint does not contain a condylar joint between the patellar surface of the femur and the patella. The patella, or kneecap, is a sesamoid bone that sits anteriorly to the femur and forms a joint with the patellar surface of the femur. The knee joint is a modified hinge joint that contains a lateral meniscus and a medial meniscus. The ACL (anterior cruciate ligament) is positioned to prevent hyperextension of the knee.
