Insall-Burstein

A) Anterior-posterior and (B) lateral radiographic views of an Insall/Burstein II TKR, with associated anatomical landmarks and implant terminology. In A, the femoral condyles are designated as medial (M) and lateral (L). 

Previously implanted Insall-Burstein (IB II) and Miller-Gallante (MG II) tibial inserts with evidence of pitting and delamination, respectively.

FIGURE 8.2t Backside wear of an Insall-Burstein II knee replacement. The inferior surface of the tibial tray shows is burnished from relative motion with respect to the tibial tray. Note the four impressions on the backside of the insert, which correspond to the four screw holes on the tibial tray. Between the screw hole impressions, the machined inscriptions on the backside of the insert have been worn away.
