Assessing Knee Ligament Tests

This video tutorial explains the posterior drawer test used to assess the posterior cruciate ligament (PCL). It begins with an introduction to the test, followed by a detailed step-by-step guide on how to perform it. The test involves positioning the patient supine, flexing the hip and knee, and applying a posterior force to the tibia. The video also covers how to interpret the test results, indicating a positive result if the tibia translates posteriorly more than six millimeters or feels soft and mushy. The tutorial concludes with suggestions for further learning, including related videos on PCL and ACL assessments.
