IN OTHER WORDS IF AN INDIVIDUAL IS AFFLICTED (ACL TEAR), IT IS THE RATE IN WHICH A TEST (ANTERIOR DRAWER TEST) WOULD PRODUCE A TRUE POSITIVE VERSES THE RATE IN WHICH THE
TEST WOULD PRODUCE A FALSE POSITIVE. THE AMOUNT OF TIMES THE TEST IS RIGHT (IDENTIFYING AN AFFECTED INDIVIDUAL AS SUCH) WOULD
CONTRIBUTE TO A HIGH SENSITIVITY RATE.

SPECIFICITY- IS THE ABILITY TO CORRECTLY IDENTIFY A TRUE NEGATIVE RATE.

AGAIN IF AN INDIVIDUAL THINKS THEY HAVE A TORN
ACL, AND THE ANTERIOR DRAWER TEST IS PERFORMED AND IS CORRECTLY IDENTIFIED AS NEGATIVE; THAT WOULD CONTRIBUTE TO A
HIGH SPECIFICITY RATE. IN OTHER WORDS CORRECTLY IDENTIFYING A HEALTHY INDIVIDUAL AS SUCH. GET IT? GOOD. I HOPE I’M RIGHT.
