Radiographic Evaluation of the Knee

- Discussion:
    - complete knee series should include an anteroposterior, lateral, & axilla view as well as a tunnel view in skeletally immature pts;

- Specific Views:
    - Axilla View
    - Lateral Radiograph
    - Tangential Patellar Views
    - Tunnel Radiograph
    - X-ray Features of OA
    - X-ray Features of RA
    - Anterior Posterior View:
          - femoral/tibial angle
          - medial and lateral joint space
          - size, position, and integrity of patella;
          - clinical findings:
                - bipartite patella
                - osteochondritis dissecans;
                - calcification of origin of MCL (Pellegrini-Stieda Phenomenon);
          - technique:
                - pt is supine w/ knee fully extended & leg in neutral position;
                - central beam is directed vertically to knee w/ 5-7 deg cephalic tilt
