Figure 1. Quantitative Pivot Shift Measurement.

Figure 1

An iPad Screenshot demonstrates a graphical representation of a quantitative pivot shift measurement. Surface markers (not shown) are placed on the lateral femoral epicondyle, Gerdy’s tubercle, and the fibular head. The iPad video camera then records the pivot shift maneuver and calculates the lateral compartment translation. The 4.027mm distance displaced in this figure is then multiplied by a factor of 3 (surface markers on the skin translate 3 times less during pivot shift than the actual bone) for a total of 12.081mm of lateral tibial translation.
