Improving Knee Replacement Surgery Outcomes with Advanced Technology

Strategic Insights -

Nashville-based Tennessee Tech University, in partnership with The State of Tennessee, has issued a news release highlighting a major breakthrough in knee replacement technology. Steven Anton, an associate professor of mechanical engineering and director of the Dynamic and Smart Systems Laboratory, has received a $2.5 million grant from the National Institutes of Health to develop a self-powered "smart knee" implant. This innovative technology aims to provide real-time data on forces and motions in the joint, improving surgical outcomes for the estimated 10 to 20 percent of patients who remain dissatisfied with their results.

Key Takeaways:

  • The National Institutes of Health has awarded a $2.5 million grant to Steven Anton, an associate professor of mechanical engineering at Tennessee Tech University, to develop a self-powered "smart knee" implant.
  • The smart knee implant will utilize embedded piezoelectric transducer arrays to generate voltages, which can be measured to create a sensing system and harvested to power the system.
  • Anton has been working on this project for over a decade and has involved 20-plus students in various forms of research and development.
  • The "R01" designation is a prestigious recognition by the National Institutes of Health, awarded to less than 10 percent of applicants, and represents a significantly larger investment in Anton's research.
  • Tennessee Tech University has marked its fifth consecutive record-breaking year for externally funded research, reaching nearly $48 million in fiscal year 2025.

Statistics:

  • 10-20 percent of patients remain dissatisfied with their knee replacement surgery outcomes.
  • 9 percent of knee replacement surgeries require revision.
  • The National Institutes of Health has awarded $2.5 million to Anton's research project.
  • Less than 10 percent of applicants receive the prestigious "R01" designation from the National Institutes of Health.
  • Tennessee Tech University has secured nearly $48 million in fiscal year 2025 in externally funded research.
