The knee joint represents one of the most complex and crucial articulations in the human body, essential for mobility and weight-bearing activities. This detailed anterior view illustration demonstrates the primary anatomical structures that work together to provide stability, flexibility, and smooth movement in the knee joint. Each component plays a vital role in maintaining proper knee function and preventing injury.
Key Components of Knee Joint Anatomy
Patella (Knee Cap) The patella is a triangular sesamoid bone embedded within the quadriceps tendon. This specialized bone increases the mechanical advantage of the quadriceps muscle and protects the anterior aspect of the knee joint.
Articular Cartilage The articular cartilage covers the ends of bones within the knee joint. This smooth, resilient tissue reduces friction during movement and helps absorb shock during weight-bearing activities.

Lateral Meniscus The lateral meniscus is a C-shaped cartilage structure on the outer side of the knee. It acts as a shock absorber and helps distribute weight evenly across the knee joint.
Medial Meniscus The medial meniscus is a C-shaped cartilage structure on the inner side of the knee. It provides stability and cushioning while helping to distribute forces across the knee joint.
Lateral Collateral Ligament The lateral collateral ligament connects the femur to the fibula on the outer side of the knee. This strong band of tissue prevents excessive side-to-side movement and provides stability to the lateral knee.
Medial Collateral Ligament The medial collateral ligament runs along the inner side of the knee joint. It provides crucial stability to the medial knee and prevents excessive outward movement of the knee.
