degenerative changes of the involved stifle joint associated with a “bucket handle”
tear of the caudal body of the lateral meniscus. Surgical excision of the torn section
of meniscus was beneficial in the first patient but this patient had persistant difficulty
with the leg after exercise. Gross and microscopic pathology of the involved stifle
in the second patient showed the meniscal lesion to be associated with severe cartilage
fibrillation of the overlying lateral femoral condyle. As in human beings, the mechanism
of injury may have been placement of the foot during vigorous external rotation of
the femur with the stifle flexed. Extension of the limb from this position could have
resulted in an isolated tear of the lateral meniscus.
