Injuries
Special Tests
100
What is the insertion point for all of the quadricep muscles?
Tibial tuberosity via the patellar tendon
100
What is this abnormality?
Genu Valgus
100
What are the primary muscles tested through knee flexion strength testing?
Biceps femoris, semitendinosus, semimembranosus
100
This injury can occur due to a violent, rapid quad contraction, or a forceful, overpressure of knee flexion while the quad is contracting.
Patellar Tendon Rupture
100
This special test is the gold standard test for assessing the integrity of the ACL and should be done immediately after injury for the best outcomes.
Lachman Test
200
What is the innervation of all of the quadriceps group?
Femoral N.
200
What is it called when the patella sits inferiorly in the femoral groove due to a shortened infra patellar tendon?
Patella Baja
200
What is the normal range of motion for knee extension?
-5 to 0 degrees
200
What are two of the primary functions of the meniscus?
1. Help stabilize the joint by deepening the
tibial condyles
2. Absorb the shock of weight bearing and
decrease loading stress
3. Lubricate the joint and reduce friction
during movement
4. Make joint surfaces more congruent and
improve weight distribution by increasing
the contact area between the tibia and
femur
200
The Varus Test is used to assess which structure?
LCL
300
The MCL and LCL both resist rotation of the tibia in which direction?
Medial rotation
300
This is the abnormality that occurs from excessive hyperextension of the knee.
Genu Recurvatum
300
Which two dermatomes assess hip flexion?
L1 & L2
300
This condition is described as a herniation of the synovial cavity and fluid accumulation in the popliteal space.
Popliteal Cyst or Baker's Cyst
300
Name 2 special tests that are used to assess the integrity of the PCL
Posterior Drawer
Posterior Sag Sign
Quadriceps Active
400
Which muscle is responsible for external/lateral rotation of the flexed knee?
Biceps Femoris
400
This is the mechanism that occurs during the first 20 degrees of flexion to "unlock" the knee after it has been in full extension.
Screw Home Mechanism
400
Sensory testing over the greater trochanter would assess which dermatome?
L1
400
This condition can occur as a secondary condition to a severe quadriceps contusion.
Myositis ossificans
400
This special test is utilized to assess IT Band Friction Syndrome.
Nobles Compression Test
500
What is the origin of the rectus femoris?
Anterior Inferior Iliac Spine
500
What is the degree threshold with Q Angle that defines "excessive angulation"?
>18-20 degrees
500
The patellar tendon reflex is associated with which nerve roots?
L2-L4
500
This is the condition in which the articulating surface of the patella is softened, roughened, and eventually degrades, causing pain and inflammation of the knee.
Chondromalacia Patella
500
Name 3 special tests for the meniscus
Joint Line Tenderness
McMurray's
Apley's Compression/Distraction
Thessaly's Test
Ege's Test
