The Lunge Lesion

ISOLATED ARTICULAR CARTILAGE LESIONS OF THE FEMORAL TROCHLEA

"The Lunge Lesion"

R.L.Morgan-Jones, M.J.Cross

ABSTRACT

A retrospective review of 1317 consecutive arthroscopies was undertaken to confirm the presence of an isolated femoral trochlea chondral lesion. 79 patients were identified with significant trochlear lesions. 11 of these had isolated trochlea chondral injuries without concomitant retropatella, condylar or other internal derangement of the knee. We describe the aetiology of this isolated lesion and discuss the potential mechanisms of injury.
