Discoid Meniscus
Discoid Meniscus is a congenital variation where the meniscus is abnormally shaped like a disc instead of a crescent, making it more prone to tearing and instability, especially in the lateral meniscus.
Symptoms
- Clicking or popping in the knee
- Pain on the outer side of the knee
- Swelling and tenderness
- Occasional knee locking or catching
- Instability during activity
Causes & Risk Factors
- Congenital anatomical variation
- Increased activity in children or adolescents
- Sudden twists or knee trauma
- Family history of knee issues
Diagnosis
- Physical examination and McMurray’s test
- MRI for confirming the discoid shape
- X-rays may show increased joint space
Effective Treatment Options
- Conservative management if asymptomatic
- Physiotherapy to strengthen surrounding muscles
- Arthroscopic surgery to trim or reshape the meniscus
- Rehabilitation for joint stability post-surgery
Frequently Asked Questions
Is surgery always needed for discoid meniscus?
No, asymptomatic cases may not require surgery and can be managed with physiotherapy.
Can a discoid meniscus heal on its own?
Tears may not heal on their own, but symptom control and muscle support often help manage the condition.
