posterior drawer sign, an orthopedic test used to determine laxity of the posterior cruciate ligament of the knee. The patient is positioned with hips at 45 degrees and knees flexed at 90 degrees while the examiner stabilizes the foot and pushes the tibia backward. Also, with both the hips and knees flexed at 90 degrees, the examiner holds the heels together and observes the knees to compare the relative posterior sag of the tibia.

| The CD chapter on the knee, for example, has short video clips (with accompanying text) that demonstrate passive knee extension/flexion, passive valgus/varus movement of the knee, passive lateral/medial rotation of the knee, anterior/posterior drawer test, medial/lateral drawer test, resisted extension/flexion of the knee, patellar tap, eliciting fluctuation, and palpation for synovial thickening. 26) The sensitivity and specificity for the anterior drawer test performed by orthopedic surgeons were reported as 76% and 86%, respectively. These trials were followed by three trials of a manual maximum anterior drawer test in which the examiners placed their free hand just distal to the joint line on the posterior surface of the leg and applied a maximum anteriorly directed force. |
