Patella Infera



- See: Patella Alta:

- Discussion:
    - patella infera indicates an abnormally low patella;
    - it most often results from to soft tissue contracture and hypotonia of
          quadriceps muscle following surgery or trauma to knee,

- Lateral Radiograph of the Knee:
    - is used to determine patellar height;

- Management:
    - if it is asymptomatic, it will require no treatment;
    - if patella baja develops after surgery or trauma it may represent arthrofibrosis;
           which may lead to chronic pain and restricted ROM;
           - treatment involves early, aggressive ROM;
