Lachman Test for ACL tears

The Lachman test is also known under the name of Ritchie, Trillat or Lachman Trillat test and it is described as the most valid test by a meta-analysis of Benjaminse et al. (2006) with a sensitivity of 85% and a specificity of 94%

Experts recommend to first exclude a PCL injury before you conduct the test for an ACL tear. The reason for this is that the tibia sags posteriorly with a PCL injury which could give you the impression that there is a lot of movement of the Tibia when you conduct an ACL test so you could have a false positive in the end

To perform this test have your patient in supine line position and bring your patient’s tests leg into 30 degrees of flexion. Fixate the femur with your other hand Bring the tibia into slight external rotation and then try to translate the tibia anteriorly

This test is positive if you experience a soft or mushy and feel or if the anterior.

Translation of the Tibia in the injured leg is at least three millimeters greater compared to the uninjured leg. Please keep in mind that your test results in a chronic situation will always be more valid than in an acute situation. The reason for this is that swelling and muscle spasms in an acute situation will have a negative influence on your test results.

    The Assessment E-Book (Spanish Version) Excelente Libro electrónico, me gusta que esta basado en la evidencia clínica y me apoya mucho para mi practica clínica. Es el mejor libro que he visto de evaluación, y me gusta mucho que esta en constante actualización, estaría bien meter más evaluaciones funcionales, que ya comienzan a subir en los videos con la nueva integrante mujer al equipo. Gracias kai y Andreas.

    The Assessment E-Book I can’t believe this extremely inconvenience interface of this book. I’m used to reading my physio books with kindle, ipad just swiping the page back and forth, but this book , you need to tap the arrow on the left corner of the book to turn the page..even space bar and enter key don’t work to turn the page..it’s feel like read a book in the computer in 1990s..

    The Assessment E-Book A must-have for all physiotherapists, osteopaths and manual therapists. The authors conducted an extensive research on assessment tests in manual therapy. I find it very easy to read. The more I read the more I learn. Thank you!

    The Assessment E-Book Very helpful during my study and making clinical decisions. You have made the test descriptions perfect for every region! Compliments! Loving the extra information (screening/guidelines) that comes with the cervical spine and the lumbar spine. Looking forward to see those as well for the other regions.

    The Assessment E-Book (Spanish Version) Un libro genial!!! Pero le doy 4 estrellas en vez de 5 ya que no me gusta el poder abrirlo solo en dos dispositivos. Tengo 2 ordenadores (uno en el trabajo), un móvil y una tablet, pudiendo abrirlo solo en dos de ellos. Por lo demás, un libro muy recomendable.

    The Assessment E-Book These are probably the best 80€ that I have ever invested in a book. Absolutly greatful for your work. It has been such a great effort, that you have put into this book and together with your videos, it really helped me to pass some exams and to later decide which assessment to use for my patients. I can only recommend this book to every single physiotherapist or physio student!!!
    thumps up, guys

    The Assessment E-Book The best way to spend 80euros. Totally worth it. The amount of work you put behind this must have been absolutely huge. Every physical or physiotherapist should own it.
    Congrats guys you’ve done an incredible job.
    I’ve learnd a lot of new things and my approach to therapy in general have totally changed.
    In one word: amazing. Keep going guys ! Best wishes from france.

    The Assessment E-Book Got me through my assessment exams with a breeze would not have been as easy and enjoyable without the assessment handbook. It provides relevant data, and insights into statistical values and the lay of the land on the research side of things. A great book and a must for any physiotherapist, student, or practitioner...
