A discoid meniscus is more prone to injury than a normal meniscus. The thick, abnormal shape of a discoid meniscus makes it more likely to get stuck in the knee or to tear. If the meniscofemoral ligament attachment to the femur is also missing, the risk for injury is even greater.

If the discoid meniscus is torn, abnormal damaged parts are removed and the meniscus is reshaped. If the periphery of the meniscus is torn or unstable, it may need to be repaired to try to preserve normal meniscal function.

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.

2021年10月30日 · A discoid meniscus is the abnormal development of the meniscus leading to a hypertrophic and discoid shaped meniscus. Diagnosis can be suspected on radiographs with (squaring of lateral condyle with cupping of lateral tibial plateau) but require MRI for confirmation (3 or more 5mm sagittal images with meniscal continuity).

2024年11月30日 · Lateral discoid meniscus is far more common than medial discoid meniscus, with the latter being rare. Although frequently asymptomatic, discoid menisci are prone to cystic degeneration with a subsequent tear. Clinical presentation may, therefore, be either incidental or with pain, locking or a 'clunk'.

Because the histology of discoid meniscus is different from that of normal meniscus, it is prone to tearing. Individuals with a discoid meniscus can be asymptomatic or symptomatic. Asymptomatic discoid menisci do not require treatment. However, operative treatment is necessary if …

What is a discoid meniscus? A discoid meniscus is an abnormally shaped meniscus in the knee. Because of its abnormal shape, it is more prone to injury than a normally shaped meniscus. The thick, abnormal shape of a discoid meniscus makes it more likely to tear or get stuck in the knee. How is a discoid meniscus injured?

2025年2月20日 · In the present study, we aimed to bridge this gap by investigating the prevalence and pattern of meniscal tear types in patients with complete DLM utilizing a comprehensive dataset comprising magnetic resonance imaging (MRI) and arthroscopic findings from a high-volume tertiary center.

What is a discoid lateral meniscus? What is the recommended treatment? If surgery is necessary, what are the details? Answers to these and other questions.

2021年1月1日 · Patients with a DLM may or may not be symptomatic with mechanical complaints of locking, clicking, snapping or pain. Symptoms often arise due to a tear in the body of the meniscus or a peripheral detachment. Asymptomatic patients usually do not require any treatment, while symptomatic patients who do not have locking are managed conservatively.
