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
