Learning the vagaries of computer-assisted total knee replacement

Safety and utility of computer-aided shoulder arthroplasty

“…11 For example, new users of computer-aided knee and hip arthroplasty systems frequently experience one or more of the following problems and frustrations during their learning curve: excessively long operative times; unintentional or unrecognized movement or loosening of a tracking device; inaccurate or irreproducible registration of anatomic landmarks; or display of illogical numerical data. For knee or hip surgeons who experience significant problems during their early experience, the learning curve may be prolonged or the technology abandoned before the learning curve is surpassed.…”

Complications of fixed infrared emitters in computer-assisted total knee arthroplasties

“…There were a few complications related either to the computer software or the tracker pins inserted in the bones [8]. The placement of the pins and screws in the bone is inevitably associated with some risk.…”

Comparison of the VetGate and SurgiGATE 1.0 computer assisted surgery systems for insertion of cortex screws across the distal phalanx in horses – an in vitro study

“…Positive responses to this surgical adjunct promising further development and fine-tuning preponderate in the literature (Laine et al 1997, Laine et al 2000, Bathis et al 2004, Sikorski and Blythe 2005, Chotanaphiti et al 2008, Easley et al 2008, Liebergall 2006.…”

“…It could be shown in spine surgery that pedicle screws could be inserted with higher accuracy using image-guided computer navigation than with conventional methods (Laine et al 2000). In total knee arthroplasty an improvement in both precision and accuracy in obtaining optimal knee alignment using CAS could be documented (Bathis et al 2004, Sikorski andBlythe 2005).…”
