Oct 15, 2024 · MRI. Features of posterior cruciate ligament tears include 1,2: PCL usually remains contiguous (~70%) although there may be complete or partial ligamentous disruption. absent PCL replaced by high T1 and T2 signal. enlarged and swollen PCL: >7 mm AP diameter of the vertical portion on sagittal imaging is indicative of a tear

Nov 19, 2024 · The posterior cruciate ligament (PCL) is one of the two cruciate ligaments that stabilize the knee joint. The ligament is intracapsular but extrasynovial and is, on average, 38 mm in length and 13 mm in width.

Nov 23, 2012 · There is little in the radiology literature regarding the MRI appearance of a torn posterior cruciate ligament (PCL). The purpose of this study was to describe the MRI appearance of surgically proven PCL tears and to emphasize previously unreported signs.

May 1, 2006 · MRI. The normal PCL is homogenously low in signal on T1 and T2-weighted sequences and demonstrates a smooth convex posterior curve (5a,6a,7a). The meniscofemoral ligaments of Humphrey and Wrisberg, when present, may be seen anterior and posterior to the PCL, respectively. MRI readily differentiates partial and complete PCL tears.

May 1, 1995 · PCL rupture is easily identified with magnetic resonance (MR) imaging by using simple signal intensity and structural characteristics. Because clinical and arthroscopic assessment of the PCL can be difficult, MR imaging can be valuable for evaluating the acutely injured knee when operative repair of the PCL is being considered.

MRI has become the gold standard in the diagnosis of PCL tears. MRI can identify meniscal, ligamentous, tendon, cartilaginous, and bony injuries, which distinguishes it from other imaging modalities.

MRI: thickened, ill-defined ligament, increased signal on all sequences (intact fibers best seen on T2w), surface of the ligament often intact. ACL injuries are more likely complete tears and will more likely require surgery. PCL injuries are more likely incomplete tears, and …

Oct 24, 2016 · The posterior cruciate ligament (PCL) is the strongest ligament of the knee. It is intra-articular and extrasynovial. The PCL arises from the anterolateral surface of the medial femoral condyle and reaches the posterior intercondylar area of the tibia.

The PCL is normally seen on MR as a well defined continuous band of low signal intensity; Partial thickness tears appear as ligament thickening and intrasubstance increased signal; Complete tears are seen as ligamentous disruption and have an abnormal contour

If the physical exam in inconclusive, then an MRI may be used to evaluate the integrity of the PCL and evaluate for other causes of knee pain. Doctors use a grade to indicate how severe your PCL injury is and to choose the appropriate treatment.
