Following its development period from 1993 to 1997 [12] in joint and spinal surgery, the OrthoPilot system has proved its technical efficiency from 1997 onwards in a cadaver study [9] and in subsequent clinical trials [7]. Moreover, the OrthoPilot navigation system has also shown substantially better results compared with the use of manual instrumentation [2–4,8,11]. It was reported in a multicenter study [1] that a statistically significant improvement in the alignment of the knee prosthesis components in respect of the mechanical leg axis and the femoral and tibial individual axes could be achieved with the OrthoPilot system as opposed to the manual technique. It should be noted here that the ≫learning curve≪ of all the centers taking part was included in the results. The superiority of the navigated implantation technique became particularly obvious when the five set parameters of o° ± 30 for the mechanical axis and 90° ± 2° for the individual axes were observed.
