OSTEOCHONDRAL LESION AND CRANIAL CRUCIATE LIGAMENT RUPTURE IN AN IMMATURE DOG STIFLE

An osteochondral flap was present on the medial femoral condyle of a s tifle of a six-month-old female rottweiler in which there was also a r uptured cranial cruciate ligament. The lesion was probably osteochondr itis dissecans, but the possibilities of it being secondary to joint i nstability or a subchondral fracture, as has been described in people with knee ligamentous injuries, are discussed.
