What is PCL intact?

The intact PCL appears to maintain the flexion gap: the flexion gap of the PCL-injured knees was greater (p < 0.001) than that of the uninjured knees.

What does normal ACL and PCL refer to in the report?

The ACL, or anterior cruciate ligament, keeps the knee from sliding forward. The PCL, or posterior cruciate ligament, keeps the knee from sliding backward. An ACL or PCL injury occurs when the ligament has been torn.

What does ACL and PCL stand for?

Posterior cruciate ligament (PCL) injury happens far less often than does injury to the knee’s more vulnerable counterpart, the anterior cruciate ligament (ACL). The posterior cruciate ligament and ACL connect your thighbone (femur) to your shinbone (tibia).

What is ACL MRI?

Anterior cruciate ligament (ACL) tears are the most common knee ligament injury encountered in radiology and orthopedic practice.

Does a torn PCL require surgery?

Complete PCL tears often require surgical treatment to regain knee stability. When the PCL pulls off a small piece of bone from the back of the lower leg (tibial avulsion), the PCL may be surgically repaired.

Is a PCL tear serious?

An injury to the PCL can cause mild to severe damage.

What does PCL pain feel like?

People who have injured the posterior cruciate ligament (PCL) of the knee often report a combination of the following symptoms: Sharp or dull pain around the back of the knee. This can occur immediately or develop in the hours or days after the injury. Swelling.

Can PCL heal without surgery?

While not as common as anterior cruciate ligament (ACL) injuries, PCL, or posterior cruciate ligament, injuries do occur and can cause some serious issues with your knee if not addressed adequately.

Can ACL injury heal without surgery?

Very minor tears (sprains) may heal with non-surgical treatments and regenerative medicine therapy. But full ACL tears cannot be healed without surgery. If your activities do not involve making pivoting movements on the knee, physical therapy rehabilitation may be all you need.

Are the ACL and PCL intracapsular?

The PCL and ACL are intracapsular ligaments because they lie deep within the knee joint. They are both isolated from the fluid-filled synovial cavity, with the synovial membrane wrapped around them. The PCL gets its name by attaching to the posterior portion of the tibia.

What does the PCL angle look like on MRI?

Since the PCL appears as an angulated structure on sagittal MR images, several indirect signs have been described to detect other ligament abnormalities, one of which is the PCL angle. The mean PCL angle is 123° and is smaller in patients with acute anterior cruciate ligament (ACL) tear but also in younger patients without ACL abnormalities [8].

What is the normal PCL angle for ACL tear?

The mean PCL angle is 123° and is smaller in patients with acute anterior cruciate ligament (ACL) tear but also in younger patients without ACL abnormalities [8]. Due to this overlap, indirect signs for ACL tears, i.e., quantitative and semiquantitative signs, should be used with care, especially in the skeletally immature patient [8].

When is mucoid degeneration of the ACL suspected?

Mucoid degeneration of the ACL is suspected when an apparently thickened and ill-defined ligament with increased signal intensity on all sequences in MRI is identified in a patient with physically intact ligament an … Mucoid Degeneration of the Anterior Cruciate Ligament: A Case Report and Review of Literature J Orthop Case Rep.

What are the signs of an anterior cruciate ligament (ACL) injury?

Anterior cruciate ligament mucoid degeneration. The appearance can mimic acute or chronic interstitial partial tears of the ACL. However, in the case of mucoid degeneration secondary signs of ACL injury are usually absent. Secondary signs include bone bruising, meniscal tears, anterior subluxation of the tibia and other ligamentous injuries.
