About This File

This is the normal left knee bone model of a 56 year old male with right anterior thigh pleomorphic leiomyosarcoma. This is an STL file created from DICOM images of his CT scan which may be used for 3D printing.


The knee is composed of 3 separate joints: two hinge joints (medial and lateral femorotibial joints), and one sellar, or gliding, joint (the patellofemoral joint). These also compose the three compartments of the knee: medial, lateral, and patellofemoral. Although the knee is thought of as a hinge joint, it actually has 6 degrees of motion: extension/flexion, internal/external rotation, varus/valgus, anterior/posterior translation, medial/lateral translation, and compression/distraction. In order to provide stability to this inherently unstable knee, static and dynamic stabilizers surround the knee, including muscles and ligaments.


The proximal tibia includes the medial plateau (which is concave) and the lateral plateau (which is convex). The Proximal tibia has a 7-10 degree posterior slope. The tibial tuberosity is located on the anterior proximal tibia, which is where the patellar tendon attaches.  On the anteromedial surface of the tibia is Gerdy's tubercle, where the sartorius, gracilis, and semitendinosus attach. The proximal fibula is the attachment for the posterolateral corner structures of the knee joint. The peroneal nerve wraps around the fibular neck.


This model was created from the file STS_014.
