What's in a name:

  • Articularis Genu -  Originating from the latin roots "articularis" - pertaining to the joints,  and "Genu" - pertaining to or relating to the knee (or knee shaped).

Articularis Genu:

  • Origin: Anterior surface of distal part of the body of the femur (3, 11).
  • Insertion: Proximal part of the suprapatellar bursa (an extension of the synovial cavity of the knee joint) and Proximal anterior joint capsule of the knee (8, 11).

    • The articularis genu is a small muscle that may be blended with the vastus intermedius, but is usually distinct from it.  This muscle lies deep to the vastus intermedius and rectus femoris and inserts deep to the patella.
    •  Unfortunately, one of my favorite anatomy texts, "Trail Guide to the Human Body (14)," did not mention palpation of this muscle, but I did find some great instructions on palpation at http://www.lastsite.ca/blog/chronic-knees/. (Lots of great info on this blog)

      "To find the articularis genu, palpate the quadriceps at its distal attachment on the patella, gently investigate medially, with your index and 3rd finger under vastus medialis, and laterally with thumbs under vastus lateralis. Attempt to pinch or connect your fingers and thumbs together. This is where you will find a tight, dense tissue that has very little side-to-side and/or superior to inferior movement. This can be quite tender for the
