The LaPrade classification system of meniscal root tears characterizes meniscal root tears based on morphology. The system was originally conceived based on arthroscopy ^1,2.

Usage

It has to be emphasized that this is a primarily arthroscopic classification system, however, the same morphological changes can be often appreciated on MRI too, thus facilitating prompt management ³.

Classification

type 1: partial, stable root tear
type 2: complete radial tear within 9 mm from the bony attachment of the meniscal root
type 3: bucket handle tears with detachment of the meniscal root
type 4: complex/oblique tears with complete root detachment
type 5: bony avulsion fracture of the meniscal root
