Abstract
Revision total knee arthroplasty (RTKA) is a skill-demanding intervention presenting several technical challenges to the surgeon due to bone deficiencies and lack of anatomical references. Computer-assisted navigation systems can potentially solve these problems. An innovative computer-assisted surgical technique for RTKA is presented. The system is image free. Based on anatomical landmarks acquired on the patient, the system automatically plans the intervention, and provides the surgeon with tools to analyse and modify the proposed plan and to accurately reproduce it on the patient. Although we performed few cases with this navigated procedure, early results obtained demonstrated to be very promising.
