The posterior cruciate ligament (PCL) is the strongest and largest intra-articular ligament in human knee and the primary posterior stabilizer of the knee. It comprises of 2 functional bundles: the larger anterolateral bundle (ALB) and the smaller posteromedial bundle (PMB).

To test the integrity of the posterior cruciate ligament (PCL). The patient is supine and the knee to be tested is flexed to approximately 90 degrees. The examiner then sits on the toes of the tested extremity to help stabilize it.

Jul 9, 2022 · If your healthcare provider suspects a PCL tear, the posterior drawer test is the best test to diagnose it. The test simply involves your practitioner inspecting and manipulating your knee to assess its movement and level of resistance.

May 31, 2023 · PCL injuries are traumatic knee injuries that may lead to posterior knee instability and often present in combination with other ipsilateral ligamentous knee injuries (i.e PLC, ACL). Diagnosis can be suspected clinically with a traumatic knee effusion and increased laxity on a posterior drawer test but requires an MRI for confirmation.

Sep 3, 2020 · There are two different ways it may be performed. The first is the opposite of the anterior drawer test. Absence of a discrete endpoint with posterior force applied to the tibia is considered positive. The second approach is positive if anterior force applied to the tibia corrects a posterior subluxation or “sag” of the affected knee.

Special tests for the ligaments of the knee. Anterior Cruciate Ligament Test, Medial and Lateral Collateral Ligaments Tests, Valgus and Varus Stress Tests, Posterior Cruciate Ligament (PCL) Tests, Posterior Drawer Test, and Quadriceps Active Test.

Oct 20, 2017 · REVERSE PIVOT SHIFT TEST helps to diagnose acute or chronic posterolateral instability of the knee. A significantly positive reverse pivot shift test suggests that the PCL, the LCL, the arcuate complex and the popliteofibular ligament are all torn. The test begins with patient supine with the knee in 30° of flexion.

To follow is the description of two functional tests, as-of-yet undescribed in the literature, that can be used as adjuncts for the diagnosis of a PCL injury: the Posterior Functional Drawer test (PFD), and the Proximal Tibial Percussion test (PTP).

Feb 28, 2025 · The Posterior Drawer Test is considered positive if a posterior displacement of the proximal tibia, relative to the distal femur, more than 5 mm, or a “soft” end point, indicates posterior cruciate ligament insufficiency.

Nov 29, 2022 · PCL Special Tests. The posterior draw test, posterior Lachman tests and posterior sag sign are orthopaedic tests, used to assess the PCL injury, indicated by pain and/or laxity. They can sometimes be referred to as PCL R tests, as they are used to assess for a PCL rupture.
