Meniscal Injury of the Stifle

The meniscus is a crescent-shaped piece of cartilage that sits between the bones of the stifle (knee), acting as a cushion and stabiliser during movement. When this structure tears or becomes damaged—often in dogs with cruciate ligament problems, but sometimes on its own—it can alter the way the joint moves and feels. The injury may happen suddenly or develop gradually as the cartilage wears down. Owners often notice a distinct click or pop when the dog walks, lameness that seems to persist or worsen despite rest, or reluctance to bear full weight on the leg. In some cases, a meniscal injury is suspected after a dog has had cruciate surgery but continues to show discomfort. The presentation can vary: some dogs show subtle stiffness, others a more obvious limp. This page explores the patterns that may suggest a meniscal problem, what happens inside the joint when the cartilage is compromised, how clinicians investigate the stifle to identify meniscal damage, and the range of surgical and non-surgical approaches that exist. The aim is to help you understand what a meniscal injury involves and how it is typically managed.
