Area of Science:

  • Orthopaedic surgery
  • Biomedical engineering
  • Medical robotics

Background:

  • Knee arthritis, a degenerative joint disease, causes pain and dysfunction, with end-stage osteoarthritis often requiring Total Knee Arthroplasty (TKA).
  • Conventional TKA faces challenges with prosthesis positioning due to human factors, leading to complications like pain, wear, and loosening.
  • The development of joint robots in China aims to enhance surgical precision and outcomes for knee replacement procedures.

Purpose of the Study:

  • To analyze the current application status of joint robots in knee replacement surgery.
  • To evaluate the technical advantages and disadvantages of robot-assisted total knee arthroplasty (RATKA) compared to conventional TKA.
  • To provide insights into the prospective application value of robotic technology for advanced knee osteoarthritis.

Main Methods:

  • This study presents a narrative review of the historical context and current clinical applications of robots in knee replacement.
  • It examines the advantages and disadvantages of robot-assisted total knee arthroplasty (RATKA) in comparison to traditional total knee arthroplasty (TKA).

Main Results:

  • Robot-assisted technology allows for pre-operative surgical planning based on patient anatomy and intra-operative assistance via robotic arms and visual systems.
  • While promising, the clinical efficacy of RATKA is still under investigation, with limited high-quality evidence available.
  • Treatment costs for robot-assisted procedures vary, and the technology is relatively new.

Conclusions:

  • Robot-assisted total knee arthroplasty (RATKA) presents a potential advancement over conventional total knee arthroplasty (TKA) by addressing issues of prosthesis positioning.
  • Further high-quality research is essential to establish the definitive clinical efficacy and cost-effectiveness of robotic assistance in knee replacement.
  • Understanding the benefits and drawbacks of RATKA is crucial for its future application in treating advanced knee osteoarthritis.
