ANATOMY
  • Bony anatomy of the knee:

    • Tibial plateau: concave, oval medial surface; convex, circular lateral surface
    • Patella: large sesamoid bone that articulates with the trochlea; chondral defects from direct anterior trauma
  • Articular cartilage: composed primarily of water, collagen, proteoglycans, and chondrocytes; layers include a superficial gliding zone, a middle transitional zone, and a deep radial zone
  • Cortical bone (compact bone) and cancellous bone (spongy or trabecular bone) are found deep to the articular cartilage.
