Robot-assisted knee arthroplasty: Analyzing the learning curve and initial institutional experience

Area of Science:

• Orthopedic surgery
• Robotics in medicine
• Surgical technology

Background:

• Robot-assisted total knee arthroplasty (rTKA) is a developing surgical technique.
• Understanding the learning curve for rTKA is crucial for widespread adoption and training.
• Surgeons face a learning curve when transitioning to robotic surgical systems.

Purpose of the Study:

• To evaluate the surgical duration of robot-assisted total knee arthroplasty (rTKA) compared to conventional total knee arthroplasty (cTKA).
• To assess the impact of surgeon experience on rTKA surgical times.
• To identify the number of procedures required to overcome the learning curve in rTKA.

Main Methods:

• Comparison of surgical times between initial stage and proficiency stage surgeons performing rTKA.
• Benchmarking rTKA surgical times against conventional total knee arthroplasty (cTKA) procedures.
• Analysis of individual surgeon learning curves for robotic system adaptation.

Main Results:

• The learning curve for rTKA is highly variable among surgeons, influenced by individual skill and aptitude.
• Proficiency stage surgeons achieved rTKA surgical times comparable to cTKA after approximately 30-40 procedures.
• Early stages of rTKA may involve longer surgical durations compared to cTKA.

Conclusions:

• Surgeon proficiency significantly impacts rTKA surgical efficiency.
• Approximately 30-40 rTKA procedures are needed for surgeons to reach proficiency and comparable surgical times.
• Continued research indicates potential for improved clinical outcomes and reduced complications with robotic assistance in total knee arthroplasty.
