Its application has extended to a growing number of fields over the past 15 years. In the field of orthopedic surgery, its primary application is prosthetic surgery, particularly of the knee, where it aims to improve the reliability and accuracy of prosthesis implantation. The systems currently used are almost exclusively \u201cpassive systems,\u201d which allow the surgeon to achieve the best possible position for the cutting templates, with the surgeon maintaining control over the procedure and performing the bone-shaping tasks.<\/p>\n

<\/strong>Preoperative systems.\u00a0<\/strong>The latest systems require a scanner or preoperative MRI, <\/strong>enabling acquisition of the knee and entire lower limb, for which the surgeon will choose cutting and prosthetic implantation axes. Cutting templates specific to the patient are made. During surgery, they are applied to the joint extremities (for a knee, the femur inferior extremity and the tibia superior extremity). This allows the surgical intervention to be performed with great precision according to the pre-surgical planning based on MRI or scanner data. This is the most recent technique, and 4 to 5 weeks are necessary to prepare tailor-make material for the patient. However, when using this technique, operative time and bleeding are decreased, as compared to standard procedures or navigation systems<\/li>\n<\/ul>\n
