Laboratory Studies

Laboratory studies are not indicated unless other diagnoses are being evaluated. Preoperative investigations are requested as required.


Imaging Studies

Radiography of the knee is the main imaging study. Findings are diagnostic of the condition. The tibial tubercle (tuberosity) is imaged on a lateral radiograph with the leg in slight internal rotation. Oblique views of the proximal tibia may help reveal the extent of the fracture. Radiographs of the contralateral knee may show evidence of Osgood-Schlatter disease.

Other forms of imaging are not performed routinely; they are requested as required if alternative diagnoses are being considered.
