Which joint in the dog has menisci?

The stifle joint, also known as the knee joint in dogs, is the correct answer because it contains menisci, which are crescent-shaped cartilaginous structures that provide stability and cushioning. The menisci in the stifle joint act to absorb shock and prevent the femur from grinding against the tibia during movement, helping to stabilize the joint during activities such as walking, running, and jumping.

In contrast, other joints like the hock (ankle joint), shoulder, and wrist do not contain menisci. The hock joint comprises various bones and ligaments but lacks the specialized cartilaginous structures found in the stifle. The shoulder joint, primarily a ball-and-socket joint, relies more on the musculature and ligaments for stability rather than menisci. The wrist joint, while complex, also does not feature menisci, instead being supported by various ligaments and articular discs. Understanding the role of menisci in the stifle highlights their importance in joint health and function, especially in active animals like dogs.
