Traumatic fracture of the patella in 11 cats

Traumatic patellar fracture in cats mainly occurred in male neutered cats with an average age of four years, six months and a mean weight of 4.8 kg. Patellar fractures were concurrent with long bone fractures and cruciate ligament rupture or occurred after gunshot. The patella luxated medially or laterally in four cats. Fracture fragments were usually small, either from the proximal pole (base) or distal pole (apex) or longitudinal fragments. Treatment was by fragment excision when the fragment was small or by reconstruction with pins and wires when fractures were comminuted. The outcome in six cats was reported as 'good' to 'normal' and three cats were 'improving' or had 'mild' intermittent lameness at the last follow up.
