Chondrolabral separation refers to a form of chondrolabral injury, where the acetabular labrum is separated from the adjacent cartilage at the articular margin.

Terminology
Chondrolabral separation is referred to as a chondrolabral injury seen in the hip. It can also occur in the shoulder joint, but similar injuries there are termed differently.
Pathology
Chondrolabral separation can occur as a result of femoroacetabular impingement with cam morphology, where the loss of sphericity of the femoral head-neck junction leads to shear forces at the chondrolabral junction during hip flexion and internal rotation. The labrum is hereby forced outward and the adjacent articular cartilage is compressed, which can then leads to a detachment of the labrum from the adjacent cartilage and transitional zone at the articular margin with possible additional chondral delamination, also known as Carpet lesion as a sequel 1-3.
Location
This type of lesion typically occurs at the anterosuperior aspect of the acetabulum 1-3
