Medial and lateral discoid menisci: a case report

Area of Science:

• Orthopedic Surgery
• Knee Anatomy
• Meniscal Abnormalities

Background:

• Discoid menisci are congenital variations of normal meniscal anatomy.
• While typically unilateral, bilateral discoid menisci are exceptionally rare.
• Associated anomalies can complicate presentation and treatment.

Purpose of the Study:

• To report an extremely rare case of bilateral medial and lateral discoid menisci.
• To highlight associated intra-articular pathologies in a patient with this condition.
• To document the surgical management and outcome for torn bilateral discoid menisci.

Main Methods:

• Case report of a 44-year-old female patient.
• Diagnostic evaluation including physical examination and imaging (details not specified).
• Surgical intervention: Meniscectomy for torn discoid menisci.

Main Results:

• The patient presented with bilateral medial and lateral discoid menisci.
• Associated findings included anomalous insertion of the medial discoid meniscus to the anterior cruciate ligament and a pathologic medial patellar plica in the right knee.
• Meniscectomy was performed for the torn menisci, with satisfactory results at the latest follow-up.

Conclusions:

• Bilateral discoid menisci, especially with associated anomalies, represent a significant diagnostic and surgical challenge.
• Prompt surgical management of symptomatic discoid meniscal tears can lead to favorable outcomes.
• This case underscores the importance of thorough evaluation for associated pathologies in rare meniscal abnormalities.
