The Role of Articular Cartilage in Joint Function Covering the ends of the articulating bones is articular cartilage, a remarkably durable yet avascular tissue composed of water, collagen, and proteoglycans. Osteoarthritis, the most common degenerative condition, involves the progressive loss of articular cartilage and the formation of osteophytes.
Understanding Knee Joint Articulations Basics
The initial contact with the ground requires a slight flexion for shock absorption, followed by a mid-stance phase where the knee extends to support body weight. The stability of this mechanism relies heavily on the dynamic support provided by the muscles, particularly the quadriceps and hamstrings, which work in concert with the static restraints of the ligaments to control motion and prevent injury.
The knee joint articulations represent a sophisticated anatomical structure where the femur, tibia, and patella converge to facilitate complex movement. Understanding the intricate mechanics of these articulations is essential for appreciating both human locomotion and the pathologies that can disrupt it.

This specialized surface is frictionless and resilient, allowing the joint to move smoothly against compressive forces. The main compartment involves the condyles of the femur rolling and sliding over the relatively flat plateau of the tibia.
