Prevalence and incidence of meniscal injuries in pediatric and adolescent patients

Meniscal injury is a common source of knee pain. Meniscus tears are sometimes related to trauma. A sudden twist or repeated squatting can tear the meniscus. The meniscus is a piece of cartilage that provides a cushion between femur and tibia. They can be damaged during activities that put pressure on or rotate the knee joint.

The young patient who presents with a meniscal tear presents a several unique challenges and considerations for the surgeon. The aim to this prospective multicenter study was to assess the prevalence and characteristics of meniscal injuries in a pediatric as well as adolescent population undergoing surgical treatment or tibial eminence fractures and also to test the possible relationships between associated meniscal lesions and patient demographics or injury characteristics.

Between April 2014 and October 2015, a total of 54 consecutive male patients with and without meniscal injuries were enrolled and were compared with regard to sex, age, height, weight, BMI, type of injury, mechanism of injury, time to surgery, Tanner stage, sexual maturity and modified Meyers and McKeever classification.

According to study results, meniscal injury was found in 20 patients. The lateral meniscus was found in 18 patients and medial meniscus involved 2 patients. The most common tear pattern was a longitudinal tear of the posterior horn of the lateral meniscus and the second most common tear was a root detachment of the anterior horn of the lateral meniscus. Higher age, advanced Tanner stage, and pubescence were significantly associated with meniscal injury.

Results showed a higher prevalence due to statistically significant relationship with increasing age and sexual maturity. Therefore, findings of the present study suggested magnetic resonance imaging before to surgery with a suspected tibial eminence fracture and for an arthroscopic approach to adequately diagnose and treat meniscal injuries.
