Summary
Discoid lateral meniscus (DLM) is a developmental abnormality. Treatment depends on symptoms, with surgery for unstable or symptomatic cases, focusing on preserving meniscus function.
Area of Science:
- Orthopedics
- Pediatric Orthopedics
- Sports Medicine
Background:
- The discoid lateral meniscus (DLM) is a congenital anomaly.
- Its exact cause remains debated, but abnormal development and deficient attachments are suspected.
- It can present differently in children and adolescents.
Purpose of the Study:
- To review the etiology, clinical presentation, and management of discoid lateral meniscus.
- To highlight the importance of early diagnosis and appropriate treatment strategies.
Main Methods:
- Literature review of discoid lateral meniscus.
- Analysis of clinical presentations and treatment outcomes.
- Discussion of surgical and non-surgical management options.
Main Results:
- In children under 10, snapping knee syndrome indicates an unstable DLM.
- Adolescent presentations mimic meniscal tears.
- Asymptomatic DLM requires no intervention.
- Symptomatic stable DLM treated with arthroscopic saucerization.
- Meniscal repair shows promise for unstable Wrisberg meniscus.
Conclusions:
- Optimal DLM management requires high clinical suspicion and current knowledge of treatments.
- Treatment strategies vary based on stability and symptom presentation.
- Preserving meniscal function is key in surgical interventions.
