Summary

Surgical residents achieve comparable accuracy to experienced surgeons in total knee arthroplasty (TKA) using computer navigation. While initial accuracy is similar, resident surgeries take longer, impacting clinic costs.

Area of Science:

  • Orthopedic Surgery
  • Surgical Education
  • Medical Technology

Background:

  • Total knee arthroplasty (TKA) is a critical procedure in surgical training.
  • Inexperienced surgeons performing TKA are associated with higher implant loosening rates.
  • Accurate implant alignment is crucial for long-term TKA survival.

Purpose of the Study:

  • To compare the accuracy of total knee arthroplasty (TKA) implantation by surgical residents versus experienced consultants using computer navigation.
  • To evaluate the impact of surgeon experience on TKA accuracy and operative time.

Main Methods:

  • Retrospective analysis of 662 consecutive TKAs.
  • Data collected from computer navigation systems, including cutting errors.
  • Comparison of postoperative mechanical axis deviation and operative time between residents and consultants.

Main Results:

  • No significant difference in cutting errors between residents and consultants during their initial navigated procedures.
  • Operative time was significantly longer for residents (139 minutes) compared to consultants (122 minutes).
  • Low and comparable rates of mechanical axis outliers (>2°) between residents (3.7%) and consultants (2.3%).

Conclusions:

  • Surgical residents demonstrate comparable accuracy to experienced consultants when performing total knee arthroplasty with computer navigation.
  • While accuracy is maintained, residents' longer operative times increase costs in teaching settings.
  • Computer navigation can facilitate accurate TKA implantation by residents, supporting surgical training.
