Key takeaways:

  • Osteotomy with patient-specific instrumentation improved correction accuracy, tourniquet time and overall OR time.
  • The use of patient-specific instrumentation did not increase costs vs. freehand correction.

BOSTON — In this video from the Arthroscopy Association of North America Annual Meeting, Michael J. Alaia, MD, FAAOS, discussed how osteotomy with patient-specific instrumentation can improve correction accuracy without increasing costs.

“We looked at about 42 patients that underwent osteotomies through a traditional freehand technique and compared that with those patients that we used patient-specific instrumentation for to obtain our correction,” Alaia told Healio.

Alaia and colleagues found patient-specific instrumentation was associated with improved accuracy of the correction, decreased tourniquet time and decreased OR time.

“When you improve OR time, that lowers overall cost,” Alaia said. “When you look at everything, including cost of the implant, the surgical time that’s saved, etc., we found the exact same prices comparing freehand techniques with patient-specific instrumentation.”
