when observing the knee during injury evaluation, the knee should be in ____ to relieve any strain on the joint structure

30 degrees of flexion

rotational capability of the tibia with respect to the femur is maximal at approximately _____ of knee _______

90 degrees; flexion

an athlete has developed a synovial herniation in the popliteal space. this condition is termed

Baker's cyst

the strongest ligament at the knee is

Posterior cruciate ligament (PCL)

the unhappy triad involves the

acl, mcl, and medial meniscus

deceleration and internal rotation of the tibia are primary mechanisms of injury for

anteromedial rotary instability

what test should be performed to confirm a suspected patellar dislocation

apprehension test

what is not a function of the meniscus

assisting the ligaments and capsule in preventing hyperflexsion

larsen-johansson disease occurs

at the tibial tubercle

a meniscal tear in which an entire longitudinal segment is displaced medially toward the center of the tibia is termed

bucket handle tear

after placing ice on an acutely injured knee, an athlete develops paresthesia down the lateral aspect of the injured knee. this could be attributed to

common peroneal nerve paresthesia

bursitis is most likely to result from

compressive force

the menisci are attached to the superior plateaus of the tibia by what structure

coronary ligaments

An A-Angle of ____ has been linked to increase patellofemoral pain

greater than 35 degrees

immediate swelling of the knee after acute injury usually indicates

intraarticular injury

closed-chain exercises for the knee include

mini-squats

_________ bursitis is often associated with running and cycling and is routinely aggravated by knee flexion

pes anserine

the arcuate complex supports

posterior knee stability

because the medial and lateral condyles of the femur differ somewhat in size, shape, and orientation, the tibia rotates laterally on the femur during the last few degrees of extension. this action is known as

screwing home mechanism

the medial meniscus is attached to the medial collateral ligament and to fibers from the

semimembranosus

the pes anserine is the common attachment of the sartorious, gracilis, and ____________

semitendinosus

the largest bursa of the body is

suprapatellar

The Q-Angle is

the angle between the line of quadriceps force and the patellar tendon

the medial meniscus can often be injured in combination with a hamstring injury because

the medial meniscus is attached to fibers of the semimembranosus

the screw-home mechanism occurs when the

tibia rotates laterally on the femur during the last degrees of the knee extension

the _________ nerve innervates all of the muscles in the hamstring group except the short head of the biceps

tibial

anteromedial instability does not indicate damage to

vastus medialis oblique

atrophy of the ____________ is nearly always evident in patellofemoral dysfunction

vastus medialis oblique

posterior knee swelling does not indicate

venous thrombosis
