Lachman Test Assessment Questions

The video tutorial explains the Lachman Test, a method to assess anterior cruciate ligament (ACL) ruptures. It highlights the test's validity, with a sensitivity of 85% and specificity of 94%. Before conducting the test, it's crucial to rule out a posterior cruciate ligament (PCL) injury to avoid false positives. The video provides a step-by-step guide on performing the test, emphasizing the importance of interpreting results in chronic versus acute situations due to potential swelling and muscle spasms. The tutorial concludes with additional resources for further ACL assessment techniques.
