What is Meniscocapsular separation?

Meniscocapsular separation is a subtype of meniscal tear in which the posterior meniscus horn pulls away from the capsule resulting in a separation of the posterior meniscal signal and the posterior tibial plateau greater than 8-10 mm.

What is the Meniscocapsular ligament?

The meniscocapsular ligament is a collagenous structure of the posteromedial corner of the knee and connects the base of the medial meniscus to the posterior knee capsule 1-3.

What is Meniscocapsular sprain?

Meniscocapsular Injury Meniscocapsular injuries are uncommon and refer to the detachment of the meniscus from capsular attachments. It is a sub-type of meniscus injury and describes a type of tear where the posterior meniscus horn pulls away from joint capsule.

What are Meniscofemoral ligaments?

The anterior meniscofemoral ligament (ligament of Humphry) is a small fibrous band of the knee joint. It arises from the posterior horn of the lateral meniscus and passes superiorly and medially in front of the posterior cruciate ligament to attach to the lateral surface of medial condyle of the femur.

What is a ramp lesion?

Ramp lesions are peripheral tears of the posterior horn of the medial meniscus that involve the meniscocapsular attachments or red-red zone and typically occur in conjunction with anterior cruciate ligament (ACL) ruptures.

What is ramp tear?

Originally, a ramp lesion was defined as a longitudinal tear of the peripheral attachment of the posterior horn of the medial meniscus at the meniscocapsular junction of less than 2.5 cm in length.

Why is it called a ramp lesion?

initially coined the term “Ramp Lesion” to describe a tear in the attachment between the posteromedial meniscus and knee capsule in ACL deficient knees (5). Since that time, multiple authors have described similar injuries to the posteromedial meniscocapsular attachment in conjunction with ACL injury.

Is lateral or medial meniscus tear worse?

However, it is well known that if a lateral meniscus is taken out, the consequences are almost always worse than having a medial meniscus resected.

Why does lateral meniscus tear with ACL?

An ACL injury can increase the chances for a lateral meniscus tear. The center of the meniscus has poor blood supply, which makes it less amenable to healing. Depending on the severity of the meniscal tear, patients may be recommended to have surgical reconstruction.

What is the function of meniscofemoral ligament?

Functions of Meniscofemoral Ligaments The mensicofemoral ligaments play an important role as stabilizers and protectors for the posterolateral femorotibial compartment. They increase congruity between the mobile lateral meniscus and lateral femoral condyle during motion of the knee.

Where is meniscofemoral ligament?

the knee joint
The meniscofemoral ligament (MFL), a small fibrous ligament of the knee joint, is a well-known anomaly that arises from the posterior horn of the lateral meniscus (PHLM) and attaches to the lateral area of the medial condyle of the femur.

What is a discoid meniscus?

A discoid meniscus is thicker than normal, and often oval or disc-shaped. It is more prone to injury than a normally shaped meniscus. People with discoid meniscus may go through their entire lives and never experience any problems. If a discoid meniscus does not cause pain or discomfort, no treatment is needed.

How do you fix a ramp lesion?

The first needle is fired at the posterior capsule, and the second needle is fired on the meniscal body. The suture is then tightened, and the surgeon can observe that the gap made by the ramp lesion is approximated. The stability of the repaired lesion and the necessity for additional suture are evaluated.

Do I need surgery for a lateral meniscus tear?

How is a meniscus tear treated? If your MRI indicates a Grade 1 or 2 tear, but your symptoms and physical exam are inconsistent with a tear, surgery may not be needed. Grade 3 meniscus tears usually require surgery, which may include: Arthroscopic repair — An arthroscope is inserted into the knee to see the tear.
