NAVIO Robotics-Assisted Partial Knee Replacement

NAVIO Robotics-Assisted Partial Knee Replacement

The NAVIO system a CT-free platform used by our Knee Replacement Specialists to perform robotics-assisted partial knee replacement. The system is designed to optimize the accuracy of bone preparation, implant positioning, and soft tissue balancing, where implant alignment is a crucial factor in determining how long a partial knee implant will last.

Partial Knee Replacement with the NAVIO system

Through an advanced computer program, the NAVIO system collects precise information about your knee for the surgeon to use and create a patient-specific surgical plan. Once the plan is determined, the surgeon uses a robotics-assisted surgical tool (the NAVIO handpiece) to accurately prepare the bone surface for implant placement.

In a NAVIO robotics-assisted procedure there is no special pre-operative preparation or post-operative recovery protocol. The system does not perform the procedure, rather it assists the surgeon by providing accuracy and precision.

Partial Knee Replacement with Traditional Techniques

Using traditional surgical methods, cutting blocks are placed on the thigh bone (femur) and shin bone (tibia) to help direct a surgical saw in removing the diseased bone and cartilage. This method has been considered technically challenging, as accurately placing these blocks can be difficult. Recently, advanced surgical techniques using robotic assistance have been developed to provide a higher level of precision and consistency.

Partial Knee Replacement, Compared To Total Knee Replacement, Offers

  • Improved patient satisfaction
    – 19% of total knee patients do not have their expectations met
    – 94% of partial knee patients have their expectations met
  • Less Post-operative Pain
  • Lower Risk of Complications
  • Improved Range of Motion. Partial knee replacement has been shown to result in a greater range of motion over total knee replacement
  • Knee feels More Normal
  • Shorter Hospital Stay
  • Faster Recovery Time
  • Minimally Invasive Surgical Techniques
  • More Options in the Future. Partial knee replacement offers more options in the future, were osteoarthritis can advance and future treatment may be needed
  • Smaller implants
  • Most insurance plans cover partial knee replacement
  • Less removal of bone and cartilage
  • No removal of ligaments
