Case: A 4-year-old girl with no relevant medical history presented with left knee swelling. Knee laxity, magnetic resonance imaging findings of anterior cruciate ligament (ACL) deficiency and discoid meniscus, and the chronicity of symptoms prompted arthroscopic ACL reconstruction and meniscal saucerization. Pain and swelling continued, and repeat arthroscopy revealed regeneration of the discoid meniscus at 18-month follow-up.
Conclusion: In this unusual case, a discoid lateral meniscus regenerated after saucerization. Regeneration could be attributed to the robust vascularity of the meniscus in pediatric patients. Surgeons should counsel about the risk of recurrence after treatment of discoid meniscus.

Article Synopsis
- Knee ligament and meniscus injuries in young athletes are increasing due to more kids playing sports and better diagnostic techniques like MRI.
- Meniscus injuries can happen in normal menisci or due to congenital issues, with treatment options including meniscoplasty and repair, primarily focusing on preserving the meniscus.
- ACL injuries and tibial spine fractures have specific treatment protocols, with surgical options being standard for tibial spine fractures, while ACL tears can be treated surgically or through rehabilitation, especially in young patients.

Purpose: The literature on factors predisposing to meniscal tears in the paediatric population focuses on concomitant injuries such as anterior cruciate ligament rupture (ACL) or abnormal meniscus morphology such as discoid menisci. Patella alta has been associated with ACL ruptures but its association with meniscal tears has not been described. The purpose of our study was to evaluate whether abnormal patella height is associated with isolated meniscus tears in skeletally immature patients METHODS: We retrospectively analysed all patients under 16 years of age who had an isolated meniscal tear diagnosis confirmed on arthroscopic surgery.
