Abstract
The clinical entity termed the pivot shift was studied in cadaver specimens and its significance was evaluated. It was found to be highly correlated with a tear of the anterior cruciate ligament, and it corresponded to a sudden anterior-internal rotation subluxation-dislocation of the tibia and posterior horn of the lateral meniscus beneath the lateral femoral condyle.
