OMNIBotics Robotic-Assisted Knee Replacement

Patient Specific Surgery

We’re all different! OMNIBotics surgery uses a patented Bone Morphing™ technology that quickly builds a 3D virtual model of your knee during surgery.  This allows your surgeon to accurately plan and execute a customized surgery that is specific to your knee.

Precise Leg Alignment

Studies show that revision rates are reduced and implant longevity is increased when the knee implant is properly aligned to your body’s mechanical axis1. Proper alignment helps ensure everyday stresses on the knee are evenly distributed.

Using the custom 3D model, the OMNIBotics software provides your surgeon with a live virtual plan to accurately create a knee replacement specifically aligned to your body’s mechanical axis.  The surgeon uses the OMNIBot™ cutting guide to ensure the plan is carried out with robotic precision to help ensure your new knee is well aligned.

Soft Tissue Balancing with BalanceBot™

One of the most important factors for a successful total knee replacement is to ensure the ligaments and other soft tissues have equal tensions on both sides of the knee. If the ligaments are tighter on one side, they can cause pain and even reduce the length of time the implant lasts2.

To solve this tightness issue, often surgeons make tiny incisions in the tight ligaments to try and make them the same tension as the looser ligaments on the other side. Unfortunately, these small incisions are imprecise, and may lead to additional swelling and pain.

OMNIBotics is the only knee procedure that has a robotic instrument, the BalanceBot™ to help your surgeon assess and balance your knee. This device is designed to reduce the need for these additional incisions in your ligaments.

Getting Back to Action, and Staying There!

The OMNIBotics total knee replacement procedure can help you return to a more active daily lifestyle. By incorporating a less invasive protocol, and advanced tools such as Bone Morphing™, OMNIBot™, and BalanceBot™, OMNIBotics patients may experience a quicker recovery with less pain3.

Do I Qualify for OMNIBotics Surgery?

Almost all patients who have been identified as candidates for total knee replacement could benefit from OMNIBotics. It is important that you speak to your physician about your options.

FAQs:

Q. What benefit does an OMNIBotics procedure provide to me as compared with conventional total knee replacement?

A. Computers have improved how we perform complex tasks in our daily lives, and this includes joint replacement surgery. Traditional knee replacement often relies on manual instruments and imperfect visual assessments. OMNIBotics uses specialized tools along with a computer to achieve results with greater accuracy and precision.* For those undergoing total knee replacement surgery, this means a better chance of improved knee implant alignment which could extend the life of the implant as well as improve knee joint functionality.

Q. What about the other robotic knee replacement procedures available?

A. Launched in 2010, OMNIBotics has the most clinical history of any robotic-assisted total knee replacement solution on the market. The procedure couples robotic technology with high performance implants to help minimize the chance of needing further surgery. OMNIBotics is the only total knee procedure that offers a robotic ligament tension device, the BalanceBot, which is used to help surgeons balance the knee’s ligaments during the procedure.

Q. How does OMNIBotics compare to “patient-specific” procedures?

A. Patient specific cutting guides or patient specific implants base surgical plans and implant placement on pre-operative CT scans, MRIs, and X-rays. They offer little flexibility if the surgeon encounters unforeseen differences during the operation due to changes in anatomy between the scan date and the day of surgery. OMNIBotic knee replacement gives the surgeon flexibility to make fine-tuning adjustments during the operation and provides real time interactive assessment of your joint function.

Q. What role does robotics play in the OMNIBotics™ procedure?

A. OMNIBotics technology helps maximize the surgeon’s ability to execute the surgical plan, which is customized during the procedure by the surgeon to optimize implant placement for every patient’s anatomy. The OMNIBot™ cutting guide helps positions the surgical saw precisely as directed by the surgeon’s plan, and the surgeon executes the procedure. The BalanceBot™ robotic ligament tension device can be used by the surgeon to evaluate the knee’s soft tissue balance, helping to ensure overall knee stability.
