Area of Science:

  • Orthopedic surgery
  • Biomedical engineering

Background:

  • Total knee replacement (TKR) has advanced significantly.
  • However, complications involving the extensor mechanism persist.

Purpose of the Study:

  • To highlight preventable complications of TKR related to the extensor mechanism.
  • To emphasize the importance of surgical technique in minimizing these issues.

Main Methods:

  • Review of common TKR complications.
  • Emphasis on surgical technique and implant design factors.

Main Results:

  • Most extensor mechanism complications are preventable.
  • Key factors include component positioning, soft-tissue management, and patellar resurfacing.
