On the other hand, the Lachman’s test is the most sensitive examination test for ACL injury, acute and chronic. A click can be felt over the meniscus tear as the knee is brought from full flexion to full extension. Arthrocentesis of the knee, also known as joint aspiration, is used in cases, when patient has severe swelling, because the doctor may find it difficult to examine swollen knee. 20-30 degrees of flexion is important for examination of the ACL. This test is meant for evaluation of posterior cruciate ligament. The iliotibial band will reduce the tibia and create the clunk on the outside of the knee. Then take the knee into flexion. If the tibia is posterolaterally subluxed, the iliotibial band will reduce the knee as the IT band transitions from a flexor to extensor of the knee. Similar to anterior drawer test, the knee should be flexed 90 degrees and the tibia is pushed backwards. Your joints are the reason you're able to walk up a flight of stairs or go for a run in the morning.
