Physical and Mental Demand During Total Hip Arthroplasty

Area of Science:

• Orthopedic Surgery
• Robotics in Medicine
• Surgical Technology

Background:

• Total hip arthroplasty (THA) is a common orthopedic procedure.
• Minimizing surgeon fatigue is crucial for patient safety and procedural efficiency.
• Robotic assistance is increasingly explored to enhance surgical performance.

Purpose of the Study:

• To compare task duration, biometric parameters, and subjective demands between robotic-assisted THA and manual THA.
• To evaluate the impact of robotic assistance on surgeon physical and mental fatigue.
• To assess the feasibility of using wearable technology in surgical outcome studies.

Main Methods:

• Twelve robotic-assisted and manual THAs were performed on six cadaveric specimens.
• Wearable technology was employed to monitor biometric parameters like heart rate and energy expenditure.
• Surgeons completed questionnaires to subjectively assess mental and physical demands.

Main Results:

• Robotic-assisted THA demonstrated potential reductions in mental and physical fatigue compared to manual techniques.
• Biometric data and subjective feedback indicated a less demanding surgical experience with robotic assistance.
• Task duration was also assessed, though primary focus was on fatigue parameters.

Conclusions:

• Robotic assistance in total hip arthroplasty may lead to decreased surgeon fatigue.
• This technology holds promise for improving the surgical experience and potentially long-term surgeon well-being.
• Further research with larger cohorts and in vivo studies is warranted.
