    Study Notes

    Knee Biomechanics Basics

    • The knee joint alters the length of the lower extremity, provides stability during weight-bearing, and enables mobility for ambulation.

    Key Bony Structures

    • The femur has femoral condyles, which feature an intercondylar groove where the patella lies.
    • The tibial plateau is a crucial bony structure in the knee joint.
    • The fibula plays a role in alignment and lateral stability, but has no direct function in the main joints.
    • The patella is a sesamoid bone that contributes to congruency, with posterior articular cartilage.
