Summary
This study examined discoid menisci in five children, noting common pain and limited extension. Post-operative arthrography revealed regenerated menisci, similar to adult outcomes.
Area of Science:
- Orthopedic Surgery
- Pediatric Orthopedics
- Knee Anatomy
Background:
- Discoid meniscus is a congenital anomaly of the knee.
- It can cause pain, clicking, and limited range of motion in children.
- Associated anomalies, such as abnormal capsular attachments, can occur.
Purpose of the Study:
- To describe the surgical findings and outcomes in children with discoid menisci.
- To investigate associated anatomical variations.
- To evaluate the meniscal regeneration after surgical treatment.
Main Methods:
- Surgical case series of five children undergoing meniscectomy for discoid meniscus.
- Intraoperative assessment of meniscal morphology and associated anomalies.
- Post-operative arthrography to assess meniscal regeneration.
Main Results:
- Four of the five discoid menisci were of the primitive type with vascularization at the free margin.
- Limited or painful extension was a frequent symptom.
- Associated anomalies included abnormal capsular attachment and popliteus tendon course in one case.
- Post-operative arthrography in two patients showed a small regenerated meniscus.
Conclusions:
- Discoid menisci in children often present with symptoms of limited extension.
- Surgical management of discoid meniscus in children can lead to meniscal regeneration.
- Associated anatomical variations should be considered during surgical planning.
