Knee Osce Flashcards
How do we create a Q angle?
Draw a straight line from the ASIS to the center of the patella
line from patella to tibial tuberosity
Normal Q angle of the knee is ___ degrees.
15
With genu valgum, will you have a increased or decreased Q angle?
increased
With genu varus, will you have a increased or decreased Q angle?
decreased
What is genus recurvatum?
Our knees have a backwards curvature. They are hyper-extended.

Conduct at 30 degrees and neutral
+ test: Pain
Indication: MCL
Varus test
Pt lay down
Flex leg to 30 degrees; push into the tibia and abduct lower leg.
Conduct at 30 degrees and neutral
+: Pain
LCL
Anterior drawer test
Have patient knee flexed to 90 and sit on it, pull the tibia up
.
+: excessive translation
Indication: ACL injury
Lachmans test
Flex knee to 10-30 degrees,
Stabilize thigh w one hand
Pull the tibia upwards with other
+: Increased laxity
Indicate: ACL injury
Reverse Lachman’s Test
Flex knee to 10-30 degrees
One hand stabilizes thigh
Other hand pushes the tibia posterior
+: increased laxity,
Indicate: PCL injury
McMurray
Lay down with knee and hip flexed.
One hand on the ankle and other on distal femur
To test the lateral meniscus–> internal rotation and varus stress, then extend the leg
To test the medial meniscus–>externally rotate and VALGUS stress, then extend the elg
+: pain or click while extending
Apley Grind Compression
Patient is laying down on stomach with knee at 90 degrees
Apply a downward force and rotate
+: pain
Indicate: meniscul or collateral ligament tear
Apley Grind Distraction Test
Patient is laying down on stomach with knee at 90
Apply upward traction and rotate leg
+: Pain–> ligament tear
Relief of main–> meniscual tear
Patellar laxity and apprehension test
Put thumbs on medial side of patella and push medial –> laterally and ask if there is any pain
+: Apprehension
Indicate: previous patellar dislocation
Patellar compression (grind) test
Compress the patella and move it with one hand
+: pain
Indicate: inflammation
Patella-femoral grinding test
Compress the patella caudally into trochlear groove and tell pt to tighten quads
+: pain
Indicate: roughness of articular surface
