Area of Science:

  • Orthopedic Surgery
  • Biomedical Engineering
  • Robotics in Medicine

Background:

  • Manual total knee arthroplasty (TKA) is a standard treatment for end-stage knee osteoarthritis.
  • Technological advancements are improving accuracy and precision in TKA procedures.
  • Proper alignment of femoral and tibial components is crucial for knee kinematics and soft-tissue balance.

Purpose of the Study:

  • To review emerging technologies in total knee arthroplasty (TKA).
  • To outline literature on robotic-assisted TKA (RATKA) systems.
  • To evaluate accuracy, precision, soft-tissue protection, and outcomes of different navigation systems.

Main Methods:

  • Review of available literature on TKA navigation systems.
  • Classification of systems into image-based, imageless console, and accelerometer-based handheld categories.
  • Analysis of studies focusing on component alignment, soft-tissue protection, and postoperative outcomes.

Main Results:

  • Robotic-assisted TKA (RATKA) demonstrates improved accuracy in component alignment and fine-tuning of lower leg alignment.
  • RATKA offers enhanced soft-tissue protection compared to manual TKA techniques.
  • Emerging robotic systems show promise for improved postoperative outcomes and potentially cost-effectiveness.

Conclusions:

  • Robotic technology is advancing TKA, offering greater precision and improved soft-tissue management.
  • Various navigation systems exist, each with specific advantages in accuracy and application.
  • Further research into postoperative outcomes and cost-effectiveness of robotic systems is warranted.
