D
The Lachman test is performed to assess a patient's knee for stability of the anterior cruciate ligament. A positive Lachman test is demonstrated when the infrapatellar tendon slope is no longer observed as the tibia is moved forward. This means there is damage to the anterior cruciate ligament of the knee. The McMurray's test is performed to assess the integrity of the meniscus cartilage of the knee. The Drawer test assesses the knee for stability of the anterior and posterior cruciate ligaments. There is no test to assess the integrity of the infrapatellar tendon.
