- 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

Patella alta and recurrent dislocation of the patella.

Infrapatellar contracture syndrome:  An unrecognized cause of knee stiffness w/ patellar entrapment and patella infera.
