Which joint contains menisci?

• A. Elbow joint
• B. Shoulder joint
• C. Stifle joint
• D. Wrist joint

Answer: (C)

The stifle joint, commonly referred to as the knee joint in quadrupeds, contains menisci which are C-shaped cartilaginous structures situated between the femur and tibia. These menisci serve several important functions, including providing cushioning and shock absorption, improving joint stability, and facilitating the congruence of the articulating surfaces. The menisci help to distribute weight evenly across the joint and allow for smooth movement by reducing friction, thereby enhancing the overall functionality of the stifle joint. In contrast, the elbow, shoulder, and wrist joints do not contain menisci. These joints have their own unique structures and supporting elements, such as ligaments and bursae, but lack the specialized cartilaginous menisci found in the stifle joint. Understanding the presence of menisci in the stifle joint is crucial for comprehending joint mechanics and the implications of injuries that may affect the cushioning and stability provided by these structures.
