Fig. 3From: Pressurized carbon dioxide lavage reduces the incidence of a radiolucent line around the tibial component two years after total knee arthroplastyMethods for measurement of cement penetration. Measurements of cement penetration were collected on digital radiographs with a digital ruler calibrated to the thickness of each tibial baseplate (7 mm) (A), which was identical for all sizes of this particular implant. The maximum value of cement penetration was measured for each of the medial (B), lateral (C), anterior (D), and posterior (E) baseplate zones as defined by the Knee Society Radiographic Evaluation SystemBack to article page
