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 23, 2012 · Sagittal fat-suppressed T2-weighted MR image (TR/TE, 4,000/70) of posterior cruciate ligament (PCL) shows tibial avulsion fracture. Thin piece of cortical bone (arrow) is avulsed from tibia at insertion of PCL. PCL is redundant and retracted proximally.

Purpose Little is known about risk factors for sustaining a posterior cruciate ligament (PCL) rupture. Identifying risk factors is the first step in preventing a PCL rupture from occurring....

A magnetic resonance imaging (MRI) scan was ordered, the results of which showed a chronic complete tear of the PCL and a torn medial meniscus (Figure 2). After the MRI, the results were discussed with the patient in clinic.

Both PCL tears and MRI findings suggestive of PCL mucoid degeneration show ligament thickening and increased PCL signal inten-sity. Tram-track PCLs are usually asymptomatic and typically have no ligamentous instability. al fibers (Fig. 1) is an appearance analogous to the classic “celery stalk” morphology of ACL mucoid degeneration [4].

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.

The PCL is usually injured as the result of stretching deformation; on MRI, the ligament maintains continuity as a single structure with apparent thickening. On sagittal T2-weighted images, an anteroposterior diameter of 7 mm or more is highly sugges-tive of a torn PCL. Increased intrasubstance signal intensity in the PCL on proton-density

Jan 21, 2022 · Magnetic resonance imaging (MRI) is the preferred examination for evaluating posterior cruciate ligament (PCL) injuries. It is the most sensitive and the most widely used modality for...

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 …

A positive sag sign is characteristic of PCL injuries and results when gravity pulls the tibia downward greater than 10 mm. Clinicians can also use the posterior drawer test to evaluate the injury. A positive drawer sign occurs if the patient’s tibia slides posteriorly.
