    Study Notes

    Basic Anatomy of the Knee

    • The knee joint has three main functions: to alter the length of the lower extremity, provide stability during weight bearing, and facilitate mobility for ambulation.

    Bone Structure

    • The femur has femoral condyles, which are important for the knee joint's function.
    • The intercondylar groove is a key feature of the femur.
    • The tibial plateau is a critical part of the tibia that interacts with the femur.

    Other Important Structures

    • The fibula does not have a significant function in the main joints.
    • The patella has a posterior articular cartilage that plays a role in the knee joint.

    Stability of the Knee Joint

    • The knee joint is very stable, with stability being a key characteristic of its anatomy.
