Area of Science:

  • Orthopedic Surgery
  • Biomedical Engineering

Background:

  • Total knee arthroplasty (TKA) has seen success since the 1970s, driven by alignment and ligament balance principles.
  • Sophisticated instrumentation has advanced TKA, yet alignment and stability errors remain a challenge.

Discussion:

  • Mechanical jigs have not significantly reduced error margins in TKA.
  • Intraoperative feedback in TKA is difficult to teach and learn, impacting decision-making predictability.

Key Insights:

  • Errors in alignment and stability persist despite advancements in TKA instrumentation.
  • Current methods for error reduction in TKA have plateaued.

Outlook:

  • Computer-assisted TKA presents a promising avenue for improving surgical predictability.
