Pivot Shift (Test of Macintosh)

Rotary instability

62
Q

Reverse Pivot Shift (Jakob test)

A

-Pt lies supine with knee flexed to 70-80 with ER of tibia
-Gravitiy assists the knee into extension as examiner leans slightly against the foot and provides valgus force
-As the knee approaches 20 degrees flexion, you can feel and see lateral tibial plateau move anteriorly from a posterior subluxation
-Positive test is a reduction of the tibial head
Rotary instability

63
Q

Ober’s Test

A

Pt sidelying, hip and knee flexed
PT extends and ABD upper leg passively
Allow the leg to lower towards table while stabilizing pelvis
Performed with knee flexed and extended
Positive if leg remains ABD, contracture of ITB is present
