Test 2.3 Flashcards
How is the pivot shift test performed
Extend knee, flex hip, IR knee with valgus stress on knee. Apply force with palm on lateral aspect of knee causing IT band to slip
What does a positive test result in for pivot shift test
Clunk or crepitus with joint instability
What is the Hughston Jerk test
The reverse of the pivot shift
What angle should the pivot shift be performed at?
45 degrees
How is the anterior drawer test performed
Sit on foot, bend knee, place both thumbs on tibial tuberosity
Does Lachmans and anterior drawer test linear or rotational integrity
Linear integrity
Does pivot shift test rotational or linear integrity
Rotational integrity (specifically anterior lateral instability)
What does the Slocums test, test?
Anterior-medial and anterior-lateral instability and rotational integrity and capsules within the knee
How do you test anterior medial instability for Slocums
Point toes outward and drawer forward
How do you test anterior-lateral instability for Slocums test
Point toes inward and drawer forward
What test is done first the Lachmans for Pivot shift
Lachmans
Which is bigger PCL or ACL and what is the PCL responsible for Static or Phasic movement
PCL is bigger and responsible for static movement
True or false
PCL replacement usually uses a cavider graft
True
How is do you perform Godfeys (posterior sag)
Both legs are flexed with the eyes at leg level look to see which tibial tuberosity drops more due to gravity
How is Quadriceps active test performed
Look for position of tibial tuberosity and a positive test results in a pull tibial forward b/c no PCL is resisting it while they contract quads
