“ GET IT RIGHT THE FIRST TIME”
Stulberg used navigation to assess the position of knee components implanted with traditional methods and found that only 4 of 20 knees were implanted within 3 degrees of ideal component position in all planes.

The Ci System is an advanced, intuitive Computer Assisted Surgery System which facilitates better planning, simulation and step by step verification of surgical procedures allowing surgeon to get perfect, surgeon defined alignment, time after time increasing the longevity of the implant eliminating the need for a second surgical procedure in older patients. Getting it right the first time avoiding revision surgical procedures which are much more costly and have a higher complication rate and are done in patients who have aged more and deteriorated medically.
Computer-assisted surgery helps surgeons align the patient’s bones and joint implants with a degree of accuracy not possible with the naked eye. Do not fear, The surgeon performs the surgery. The computer simply puts together all of the information coming in from the patient and the instruments and tells the surgeon where the precise cut should be made. Given that every patient's knee geometry is different, this level of patient-specific, computer-guided accuracy is unprecedented in the history of knee replacement surgery.
Offers visual confirmation at each stage of the surgical procedure which allow modification of the plan during the surgical procedure according to intra-operative findings
It offers surgeons an unprecedented level of feedback information during a procedure
Enables surgeon to execute the surgery exactly as planned
Recutting option after cuts have been performed – More accurate end result
Superior soft tissue balancing
Increased accuracy every time, due to execution of a well established plan based on acquired landmarks
Less invasive and safer due to elimination of intra -medullary rods
Increased reproducibility time after time with perfect accuracy.
The life of a new joint depends on weight, activity level, age and other factors. Each patient responds differently. The most common adverse events include loosening, wear of components, osteolysis, infection, fracture, dislocation and tissue reaction. Some of the Patients, being on the heavier side require perfect component alignment because even a slight malalignment not apparent to the naked eye will severely shorten the life span of the artificial joint due to eccentric loading of the joint. Get it right the first time.
Unfortunately, using traditional techniques there is no tangible information or objective data that allows us to reproduce that result in the next patient. Navigation systems provide us with the potential to quantify data, to have dynamic intra-operative feedback and to obtain more reproducible results. Errors in component positioning and limb alignment that continue to occur using the conventional alignment jigs can be minimized through navigation instrumentation.
