Surgical procedure. For simultaneous approach to the medial and lateral femoral condyles a fluoroscope and a k-wire drill guide were used to ensure exact horizontal placement of both implants (A). Over the k-wire a cannulated headed reamer (7 mm diameter) set up the drill hole (B–D). The drill hole was enlarged by the use of a custom-made headed reamer, with a 0.1 mm smaller diameter than the specific implant for a press-fit fixation (E). The ceramic implant was positioned central in the drill hole over the k-wire with gentile impaction on the pusher (F–H).
