Purpose
To evaluate the learning curve during adoption of robotic-assisted total hip arthroplasty (THA), focusing on component positioning accuracy, operative time, and complications.
Methods
Retrospective review of the first 105 robotic-assisted THAs performed by a single surgeon, divided into three consecutive groups, assessing operative parameters and complications.
Key Findings
- Acetabular component malpositioning risk significantly decreased with surgeon experience.
- Operative times shortened progressively as the surgeon gained experience.
- The study demonstrated a clear learning curve for robotic-assisted THA.
Conclusion
Robotic-assisted THA has a learning curve during which surgical precision and efficiency improve.
What Does This Mean for Providers?
- Expect improvements in component placement accuracy and operative time with growing surgical experience.
- Early cases may require additional operative time and vigilance to minimize malpositioning.
- Structured training and case volume are important to optimize outcomes with robotic THA technology.
