What is mucoid degeneration PCL?

Mucoid degeneration of PCL can produce symptoms of pain on flexion or restricted terminal flexion. Partial excision of this Posterior Cruciate Ligament lesions and notchplasty resulted in immediate pain relief and improved range of motion without instability.

What is a mucoid degeneration?

Mucoid degeneration (MD) is a rare pathological affection of the anterior cruciate ligament (ACL). Mucinous material within the substance of ACL produces pain and limited motion in the knee.

How is mucoid degeneration treated?

Discussion: Treatment of ACL mucoid degeneration by arthroscopic resection is effective for posterior pain and flexion limitation. It results in postoperative laxity, but rarely in frank instability. Therefore, indications for ACL resection must be carefully selected.

What causes mucoid degeneration?

It is postulated that mucoid degeneration may be a predisposing factor to the formation of ACL ganglion cysts [1]. The pathogenesis of mucoid degeneration is unclear, but injury, ganglion cysts, and degenerative process have been implicated as the most likely etiologic factors in the production of this change.

What does the PCL connect to?

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 causes mucoid degeneration of the ACL?

The pathogenesis of mucoid degeneration of the ACL remains unknown. Some theories suggest that it may simply be the result of senescent degeneration, while others suggest that it may evolve from the synovial tissue entrapment between ACL fibers, either congenital or acquired (3).

What is thickening of ACL?

Mucoid degeneration of anterior cruciate ligament (ACL) Mucoid degeneration of ACL is a disease affecting ACL in which mucoid like substance (glycosaminoglycans) gets interspersed within the substance of ACL and as a result ACL gets thickened.

Can a degenerative meniscus heal?

Core tip: The healing potential of chronic degenerative menisci remains poor. Persistent hoop and shear stresses create complex tears in the posterior horn and midbody. Conservative treatment with anti-inflammatory medications and physical therapy may provide pain relief and improve mechanical knee function.

What is mucoid material?

mucoid in American English any of a group of substances resembling the mucins, occurring in connective tissue, cysts, etc. adjective. 2. Also: mucoidal (mjuːˈkɔidl) resembling mucus.

Is PCL worse than ACL?

Although it is larger and stronger than the ACL, the PCL can be torn. PCL tears make up less than 20% of injuries to knee ligaments. Injuries that tear the PCL often damage some of the other ligaments or cartilage in the knee, as well.

Can you bend your knee with a torn PCL?

Swelling typically occurs within 2 to 3 hours of the injury. Stiffness. Swelling may cause the knee to become stiff. A person may have trouble bending the knee, resulting in a limp or difficulty going up or down stairs.

Can ACL be healed without surgery?

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. Special exercises may help train the musculature around the knee to compensate for the torn ACL and stabilize the joint.

How to diagnose anterior cruciate ligament mucoid degeneration?

Anterior cruciate ligament mucoid degeneration 1 Epidemiology. ACL mucoid degeneration is present on ~10% (range 9-12%) of 3 T MRI examinations and 2% of 1.5 T MRI examinations 6 . 2 Clinical presentation. 3 Pathology. 4 Radiographic features. 5 Treatment and prognosis. 6 See also

Can a tram track Tear cause a mucoid degeneration?

Both PCL tears and MRI findings suggestive of PCL mucoid degeneration show ligament thickening and increased PCL signal intensity. Tram-track PCLs are usually asymptomatic and typically have no ligamentous instability. Keywords: MRI, mucoid degeneration, posterior cruciate ligament

Which is better MRI or arthroscopy for mucoid degeneration?

MRI is better at detecting mucoid degeneration than arthroscopy, as the surface of the ligament is often intact. No treatment is usually required. If arthroscopy is performed, the ligament may appear entirely normal, especially using the standard anterior portal approach.

What are the secondary signs of ACL mucoid degeneration?

However, in the case of mucoid degeneration secondary signs of an ACL injury are usually absent. Secondary signs include bone bruising, meniscal tears, anterior subluxation of the tibia and other ligamentous injuries. ACL mucoid degeneration is present on ~10% (range 9-12%) of 3 T MRI examinations and 2% of 1.5 T MRI examinations 6 .
