Discoid meniscus is a congenital defect affecting the meniscus. This is caused by a defect where the shape of the meniscus is oval instead of C-shape.
The underlying cause of the condition is unknown. It is believed that this congenital issue might develop during the childhood years due to an unbalanced ligament attachment.
What are the signs?
Generally, an individual with discoid meniscus is asymptomatic which means that there are no symptoms, or he/she is unaware of having it. Nevertheless, an injury to the discoid meniscus can trigger the following symptoms:
- Evident popping sensation at the time of injury
- Swelling or rigidity of the knee joint
- Difficulty extending or straightening the knee
- Knee pain while walking
- Instability of the knee joint
Any activity that worsens the condition must be avoided. The doctor usually suggests avoiding any form of physical activity until the symptoms settle.
Management of discoid meniscus
Since most individuals with discoid meniscus are considered asymptomatic, treatment might not be needed. Nevertheless, conservative measures are suggested if the individual is suffering from minor pain such as:
- Adequate rest – any activity that worsens the condition must be avoided. The doctor usually suggests avoiding any form of physical activity until the symptoms settle.
- Full immobilization of the knee
- Physical therapy exercises
In cases where discoid meniscus triggers intense pain along with other symptoms, surgical intervention is needed.
Some of the commonly used surgical options include:
- Knee arthroscopy
- Partial meniscectomy
Prevention
At the present, there is no preventive measure for discoid meniscus. Nevertheless, maintaining mobility and strength of the knee joint can lessen the potential for damaging the joint as well as aggravating the condition.
