OMNIBotics is a robotic-assisted system used by orthopedic knee surgeons to plan and perform total knee replacement with the utmost precision. In this procedure, the worn out or damaged surface of the knee joint is removed and replaced with an artificial implant. Robotic instruments are used by the orthopedic surgeon under computer guidance to ensure the procedure is carried out precisely to plan.

OMNIBotics robotic-assisted surgery uses a patented Bone Morphing™ technology that quickly builds a 3D virtual model of your knee during surgery. This allows your surgeon to plan and execute a customized surgery with accuracy, in real-time, as per your knee joint.

OMNIBotics robotic-assisted surgery is also a one of a kind surgery that uses a special robotic instrument, the BalanceBot™ that detects ligament tension and provides soft tissue balancing. This ensures overall knee stability and a more successful outcome.

Computer guidance allows your surgeon to understand your knee anatomy and its spatial arrangement. X-rays and CT scans are taken to determine the damaged areas in your knee joint that need to be removed. Based upon the results of imaging scans and the 3D virtual model, a suitable implant is developed to provide the best fit for every individual patient. The implant is optimized to restore proper soft tissue balance and leg alignment.

Indications for OMNIBotics Robotic-Assisted Total Knee Replacement

If you have severe arthritis and joint pain that is not relieved with non-surgical treatments, your doctor may recommend OMNIBotics robotic-assisted total knee replacement to provide better results.

Procedure: OMNIBotics Robotic-Assisted Total Knee Replacement

The OMNIBotics robotic-assisted total knee replacement is performed either under spinal or general anesthesia.

  • You may be administered a neuromuscular blocker that paralyzes the muscles to prevent accidental movements during the surgical procedure.
  • You are placed in a supine position on your back. Depending on your condition, one leg may be slightly raised at an angle of 30° or 90° and the other leg is extended on the operating table.
  • A few small incisions are made in your knee joint.
  • The damaged portions of the femur are cut at specific angles using surgical cutting equipment.
  • The femoral component is placed at the end of the femur. Bone cement may or may not be used.
  • Your surgeon cuts or shaves the damaged area of the tibia (shinbone) and the cartilage. This removes any bone deformities and bony growths, as well as creates a smooth surface on which the implants can be attached.
  • The tibial component is attached to the end of the bone with screws or bone cement.
  • The tibia and femur with the new components are then placed together to form a new knee joint.
  • The rear surface of the kneecap (patella) is prepared to receive a plastic component. This ensures it glides smoothly over the new artificial knee.
  • Robotic arms are used to perform all these steps under your surgeon’s guidance.
  • After placing all the new components, the knee joint is tested for range of motion.
  • Then, the knee joint is irrigated and cleaned with a sterile solution.
  • The incisions are then closed.
  • A drain may be inserted to prevent hematoma formation depending on your surgeon’s preference.
  • A sterile dressing is placed over the incision.

Care and Recovery after OMNIBotics Robotic-Assisted Total Knee Replacement

Post-surgery, your surgeon will give you specific instructions to ensure a smooth and quick recovery. 

  • You will be prescribed pain medications to manage any discomfort.
  • You will be encouraged to walk after your surgery. You will need to use crutches, walker, or cane for weight-bearing for a few weeks.
  • You will be instructed to perform mild exercises as per your physical therapist’s recommendations to remain active. Depending on the pace of your recovery, a gradual increase in the intensity of your regular activities is recommended.
  • Complete recovery may take around 6 weeks.

Advantages of OMNIBotics Robotic-Assisted Total Knee Replacement

The OMNIBotics robotic-assisted total knee replacement offers numerous advantages over a conventional knee replacement. These include:

  • Patient-specific surgery
  • Accurate implant placement
  • Precise leg alignment
  • Longer shelf life of the implant
  • Improved accuracy
  • Performed with minimal incisions
  • Rapid recovery
  • Provides pain-free knee function
  • Reduces injury to adjacent tissues
  • Reduces length of hospital stay
  • Minimizes the need for additional surgery

Risk and Complications of OMNIBotics Robotic-Assisted Total Knee Replacement

As with any surgical procedure, OMNIBotics robotic-assisted total knee replacement may also be associated with the following complications:

  • Injury to the neighboring blood vessels or nerves
  • Knee pain
  • Blood clots in the knee or leg
  • Dislocation of the patella or implant
