Upward fixation of the patella occurs when the horse fails to release the patella from its ‘fixed’ position, with the medial patella fibrocartilage hooked over the medial trochlea of the femur. The reciprocal apparatus is then locked preventing flexion of the limb. It has been reported that the condition is more common in horses with a straight hindlimb conformation as upward fixation requires stifle extension of approximately 145°, an angle more readily achieved when ordinary extension approaches that. Others report that the condition is common in Warmbloods, Thoroughbreds, Standardbreds and ponies and may have an hereditary predisposition.
Upward fixation occurs most commonly in young horses, those that are out of condition or have other causes of hindlimb weakness that prevents the quadriceps from effectively ‘unlocking’ the patella. It is also seen more commonly in animals that are stabled or that have suffered trauma to the stifle region. Lameness may develop if the condition becomes persistent. [...]
