Leitchman test

The Lechmann test is an examination of the cruciate ligament for the diagnosis of the anterior or posterior bundle of the cruciate ligament. The positive rate of the test can be increased, which is helpful for judging the anterior or posterior bundle injury of the anterior cruciate ligament.

Normal value The anterior cruciate ligament of the knee joint at 15 to 30 degrees of flexion is a stable ligament that restricts the anterior movement of the tibia. Normal is within 0.5 cm. Clinical significance Abnormal result The test result is positive, suggesting that the anterior or posterior bundle of the anterior cruciate ligament is damaged and may have a fracture of the cruciate ligament.
