Discoid meniscus, also called disk cartilage, is a type of meniscus with an atypical shape, thicker, covering a bigger surface of tibial plateau than a normal meniscus. The anomaly is commonly seen in the lateral meniscus. A discoid medial meniscus is a very rare anomaly, and it is difficult to diagnose a bilateral discoid medial meniscus.

Some people with a discoid meniscus are also born without the ligament that attaches the meniscus to the tibia (shinbone). They are particularly likely to develop a meniscal injury. 2011-12-01 · Medial discoid meniscus is often diagnosed on meniscal tear in older patients than in the lateral meniscus. Discoid lateral meniscus tends to manifest as hypermobility (snapping knee) as of childhood, without tear, whereas discoid medial meniscus is asymptomatic in childhood until revealed by tear. I've been looking it up but was not aware of what a discoid meniscus was until 3 days ago. I've had an issue with my left knee for a few years - had an MRI said a partial tear in ACL and meniscus.

General Treatment Considerations Discoid menisci are a congenital meniscal variant commonly seen in the lateral compartment, with sporadic reporting of medial cases. It is reported to be present bilateral in up to 20% of patients. There is thought to be abnormal meniscal composition and altered knee kinematics causing increased incidence of tears and instability in the meniscus. Discoid meniscus is an abnormal meniscus that is thicker than normal and has a different shape and texture that usually affects the lateral meniscus of the knee 1).

Because of its abnormal shape, a discoid meniscus is more prone to injury than a normal meniscus. It is more likely to tear or to move out of position within the joint, which hinders normal knee movement.

Medial discoid meniscus is often diagnosed on meniscal tear in older patients than in the lateral meniscus. Discoid lateral meniscus tends to manifest as hypermobility (snapping knee) as of childhood, without tear, whereas discoid medial meniscus is asymptomatic in childhood until revealed by tear.

Most often, these people don't even What are causes & symptoms of discoid meniscus & discoid meniscus tear. Some people, however, will have knee problems related to the discoid meniscus. and the ratio of sum of the width of both lateral horns to the maximal We report a case of a 52-year-old female with medial and lateral discoid menisci in both knees. Arthroscopy revealed the lateral menisci of both knees were Symptoms of a torn meniscus include knee pain, swelling, popping, and giving way.

Discoid meniscus is a rare human anatomic variant that usually affects the lateral meniscus of the knee. Usually a person with this anomaly has no complaints; however, it may present as pain, swelling, or a snapping sound heard from the affected knee.

Discoid medial meniscus is a rarity. We present 2 cases, one with bilateral discoid medial menisci, and the other with both medial and lateral discoid menisci in the same knee. The radiological, MRI and arthroscopic findings in these knees and their association with various synovial plicae have been described. Both patients had good results after arthroscopic subtotal meniscectomy. Discoid meniscus is a congenital variant of the meniscus which can affect its size, shape and stability.

It occurs when the cartilage does not properly develop, resulting in a thicker disc- or oval-shaped meniscus. The defect most often occurs in the meniscus on the outer (lateral) part of the knee joint. Approximately 20% of individuals diagnosed with a discoid meniscus have it in both knees. Case 2: partial medial meniscectomy and reshaping were performed for the torn discoid medial meniscus on both knees. OUTCOMES: The postoperative pain and the recovery of joint function were observed.

Many people have them and don’t know it. If a patient does tear the meniscus, the orthopedic surgeon can trim out the inner part and reshape it back to the normal C-shape. In this video, I discuss their significance and how likely they are to be bilateral.

With growth and walking, the discoid meniscus evolves into its normal C-shape. In some children, the lateral A 5-year-old girl with bilateral unstable lateral DM of the complete type who presented with snapping knee syndrome. Sagittal PD images ( A and B ) of both knees show thickened posteriorly displaced lateral DM ( black arrows ) (“crimped meniscus” sign). Both menisci have an abnormally increased signal intensity ( asterisks ).

However, some people have more than one discoid meniscus, either in one or both knees. Because of its abnormal shape, a discoid meniscus is more prone to injury than a normal meniscus. It is more likely to tear or to move out of position within the joint, which hinders normal knee movement. Some people with a discoid meniscus are also born without the ligament that attaches the meniscus to the tibia (shinbone). They are particularly likely to develop a meniscal injury.

Discoid lateral meniscus (DLM) is a common anatomic variant in the knee typically presented in young populations, with a greater incidence in the Asian population than in other populations. As DLM is a congenital anomaly, the ultrastructural features and morphology differ from those of the normal meniscus, potentially leading to meniscal tears.

A small percentage of the population has an abnormal shape of the meniscus, called a discoid meniscus. Most often, these people don’t even know they have a p

Your physician will treat the discoid meniscus using arthroscopic surgery, to reshape the meniscus, and to repair any tears. Discoid medial meniscus is a rarity. We present 2 cases, one with bilateral discoid medial menisci, and the other with both medial and lateral discoid menisci in the same knee.
