An 8- to 10-year follow-up of 26 computer-assisted total knee arthroplasties.

The objective of this article was to assess the long-term follow-up of the first 26 computer-assisted total knee arthroplasties (TKAs) performed between January, 1997, and December, 1998, using the prototype of the OrthoPilot (B. Braun Aesculap, Tuttlingen, Germany). Three patients died of unrelated causes at 3, 8, and 9 years after surgery and one was lost to follow-up.

A cadaveric study to assess the accuracy of computer-assisted surgery in locating the hip center during total knee arthroplasty.

Computer-assisted technology allows the accurate location of inaccessible landmarks such as the center of the hip in total hip arthroplasty. Using 7 fresh normal cadaveric hips, we conducted 2 studies. The first study compared iliac (A) vs no iliac (B) tracking.

Reproducibility of intra-operative measurement of the mechanical axes of the lower limb during total knee replacement with a non-image-based navigation system.

Objective: The restoration of a normal mechanical axis of the lower limb following total knee prosthesis (TKP) depends on the accuracy of the intra-operative measurement of the femoro-tibial angle. We have studied the reproducibility of intra-operative measurement of the coronal mechanical femoro-tibial axis with the OrthoPilot (Aesculap, Tuttlingen, Germany) non-image-based navigation system.

Material And Methods: A consecutive series of 20 TKP (Aesculap SEARCH Evolution prosthesis) implanted by the same surgical team of two senior orthopedic surgeons was analyzed.
