- 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;
- 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
