Discoid Meniscus Treatment in Thailand

What is a Discoid Meniscus?

A discoid meniscus is a thicker, more rounded meniscus than the normal crescent-shaped structure. It is usually present from birth and most commonly occurs in the outer part of the knee. An unstable or torn discoid meniscus may cause pain, clicking, locking, and difficulty moving the knee.

What is the Importance of Timely Treatment?

Timely evaluation helps identify meniscal tears or instability, manage symptoms, preserve knee function, and reduce the risk of further cartilage damage. Early treatment can also help patients return to normal activities and sports when appropriate.

What are the Common Symptoms of a Discoid Meniscus?

• Knee Pain: Pain may occur along the outer side of the knee, particularly during movement or activity.
• Clicking or Popping: A discoid meniscus may produce audible or noticeable clicking during knee movement.
• Knee Swelling: Inflammation or meniscal irritation can cause swelling around the knee.
• Knee Locking: A torn or unstable meniscus may cause the knee to catch or temporarily lock.
• Limited Movement: Pain, swelling, or mechanical symptoms may restrict normal knee motion.
• Feeling of Instability: Some patients may feel the knee giving way during activity.

Causes and Risk Factors of Discoid Meniscus

Causes

• Abnormal Meniscal Development: A discoid meniscus develops when the meniscus forms with an atypical shape and thickness.
• Congenital Variation: The condition is generally present from birth rather than caused by an injury.
• Meniscal Injury: A discoid meniscus may be more prone to tearing or instability, which can cause symptoms.

Risk Factors

• Congenital Anatomy: Having a discoid-shaped meniscus is the primary underlying factor.
• Sports Activities: Twisting, pivoting, or repetitive knee movement may increase the risk of symptomatic tears.
• Knee Trauma: A direct injury or twisting movement can damage an already abnormal meniscus.
• Meniscal Instability: An unstable discoid meniscus may be more likely to cause mechanical symptoms.

Latest Research and Technologies in the Treatment of Discoid Meniscus in Thailand

• Thailand’s management of discoid meniscus increasingly emphasises accurate imaging, preservation of healthy meniscal tissue, and minimally invasive treatment. When surgery is required, arthroscopic techniques such as saucerization with meniscal repair are commonly used to reshape the meniscus while preserving as much functional tissue as possible. Advanced arthroscopic imaging and repair techniques can help address peripheral instability or associated tears. Ongoing research focuses on meniscal preservation, improved repair techniques, rehabilitation protocols, and long-term joint outcomes.
