Description:
Robert Osgood in the US and and Carl Schlatter from Zurich described this injury in 1903.
It occurs at the tibial tubercle apophysis, and is considered as an overuse injury seen in adolescents.
Its prevalence is greatest among boys in the 12 to 15 year age group, and usually resolves after 3 to 6 months. In some cases however, it may not resolve until the apophysis has fused.
Causes:
Description:
The ACL is a cross shaped ligament within the knee joint which attaches the tibia to the femur.
Its primary function is to prevent anterior tibial translation (forward movement of the tibia away from the knee joint). It also acts as a restraint to tibial rotation and varus/valgus distortions
When the ACL is injured, a combination of anterior translation and rotation occurs.
ACL injuries are common to most sports, and more common in females than males.
Description:
The menisci are crescent structures that act as a cushion between the femur and the tibia. The medial meniscus is on the inside of the knee and the lateral on the outside.
These structures absorb a considerable amount of compressive load from the medial and lateral femoral condyles (50% and 70% respectively)
The menisci have a degree of mobility which allows the tibia to roll and glide back on the femur during flexion.
