Knee

Question 1

Large thigh bone

Answer 1

Femur

Question 2

Medial, large lower leg bone; also known as the “shin bone”

Answer 2

Tibia

Question 3

Lateral, small lower leg bone

Answer 3

Fibula

Question 4

Triangular sesamoid bone within the quadriceps tendon that protects the knee joint; also known as the “kneecap”

Answer 4

Patella

Question 5

Tibia + femur; hinged joint. Medial and lateral compartments. Contains menisci, bursa, and many ligaments

Answer 5

Tibiofemoral joint

Question 6

Patella + femur; plane joint

Answer 6

Patellofemoral joint

Question 7

Muscles of the anterior thigh that extend the leg at the knee joint; most important muscle in stabilizing the knee joint

Answer 7

Quadriceps muscle

Question 8

Posterior thigh muscles that flex the leg at the knee joint and form he popliteal fossa

Answer 8

Hamstrings muscle

Question 9

Common tendon of the quadriceps femoris muscles that connects to the patella

Answer 9

Quadriceps tendon

Question 10

Continuation of the quadriceps tendon that connects the patella to the tibia

Answer 10

Patellar tendon

Question 11

Attaches to the anterior aspect of the tibial plateau and resists hyperextension

Answer 11

Anterior cruciate ligament (ACL)

Question 12

Attaches to the posterior aspect of the tibial plateau and prevents the femur from sliding anteriorly off the tibia

Answer 12

Posterior cruciate ligament (PCL)

Question 13

Connects the lateral femur with the lateral side of the fibula preventing side-to-side or rotational motions between the femur and tibia

Answer 13

Lateral collateral ligament (LCL)

Question 14

Connects the medial femur to the medial tibia preventing side-to-side or rotational motions between the femur and tibia

Answer 14

Medial collateral ligament (MCL)

Question 15

Cartilage between the femoral condyle and medial tibial plateau that cushions the knee joint. Firmly attached to the MCL

Answer 15

Medial meniscus

Question 16

Cartilage between the lateral femoral condyle and lateral tibial plateau that cushions the knee joint

Answer 16

Lateral meniscus

Question 17

Fluid-filled sacs that reduce friction within the knee joints; facilitate movement

Answer 17

Pes anserine and prepatellar bursae

Question 18

Diamond-shaped hollow at the back of the knee formed by the hamstrings

Answer 18

Popliteal fossa

Question 19

Division of the sciatic nerve that extends from behind the knee to wind around the head of the fibula to the front of the leg to innervate the anterior and lateral leg; often damaged by trauma to the knee such as a fibular fracture

Answer 19

Common peroneal nerve

Answer 21

Flexion

Question 22

Straightening the leg. Normal is 0 degrees.

Answer 22

Extension

Question 23

Extension of the knee past 0 degrees

Answer 23

Hyperextension
