title: Normal blood supply of the canine patella.
abstract: The normal blood supply of the canine patella was evaluated, using microangiography and correlated histology. Arterioles entered the cortex of the patella at multiple sites along the medial, lateral, and dorsal aspects. The body of the patella was vascularized uniformly, with many arterioles that branched and anastomosed extensively throughout the patella. The patella was not dependent on a single nutrient artery for its afferent supply, but had an extensive interior vascular network. These factors should ensure rapid revascularization and healing of patellar fractures, provided appropriate fracture fixation is achieved.
