Résumé :	Intra-osseous pin sites used in Computer Navigated knee Arthroplasty are known to cause complications including infection, neurovascular injury, thermal necrosis and peri-prosthetic fracture. Many studies have looked at ways of reducing these risks to improve results in computer-navigated surgery. We present our complication rates and techniques used to reduce complications in a retrospective study of 321 patients performed by a single surgeon in between 2009 and 2013. One patient was identified with a superficial pin site infection. No major complications were recorded during a mean follow up period of 31 months. Attention to detail in every aspect of pin insertion reduces the rates of both minor and major complications. In particular rates of peri-prosthetic fracture were shown to be lower when using a unicortical drilling technique compared with the use of bicortical drilling in other studies.
