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.

Oct 15, 2024 · Posterior cruciate ligament (PCL) tears are less common than anterior cruciate ligament tears. Posterior cruciate ligament tears account for ~10% (range 2-23%) of all knee injuries 2. Posterior cruciate ligament injuries are isolated in only 30% of cases and are thus commonly associated with other injuries 1,2.4:

Nov 16, 2024 · Posterior cruciate ligament (PCL) avulsion fractures are a type of avulsion fracture of the knee that represent the most common isolated PCL lesion. This typically involves the separation of the posterior tibial insertion of the PCL to variable degrees.

May 1, 2006 · Partial tears or degenerative changes of the PCL usually involve the central fibers of the PCL without loss of PCL continuity (8a). Complete PCL tears demonstrate focal interruption of the ligament fibers and alterations in PCL contour (2a,2b).

If a PCL or multi-ligament injury is suspected, plain radiographs should be performed to avoid missing a fracture or avulsion. An MRI represents the current gold standard for diagnosing ligament injuries in the knee and should always be obtained in these cases.

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.

May 1, 1995 · The posterior cruciate ligament (PCL) of the knee has received little attention in the radiology literature, but its importance in knee stability has come under close scrutiny in recent years. Unrepaired injury of the PCL can lead to chronic instability and early joint degeneration.

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.

Normal signal in the PCL on sagittal T2-weighted MRI. The normal PCL has low signal on both T1- and T2-weighted images. It appears homogenous and differs thus a little from the ACL (Figure 16) . The PCL is supported by the anterior and posterior meniscofemoral ligaments .

The indications for PCL reconstruction are: acute PCL lesions with significant instability (grade 3+), bone avulsion fractures, combined multiple ligament injuries or chronic symptomatic PCL laxity (1, 2, 4).
