INSIGHT

Common Causes of TKA Revision

  • The most common causes of TKA revision include aseptic loosening, septic failure, instability, and periprosthetic fracture.
  • Aseptic loosening is the leading cause of late revision, infection leads early revisions.
ADVICE

Preoperative Evaluation Essentials

  • Obtain original TKA indication, range of motion, infection history, comorbidities, and prior imaging.
  • Review surgical implant type and preoperative ambulatory status before revision.
ADVICE

Physical Exam and Imaging in TKA

  • Perform ligamentous exam to check for laxity and evaluate patellar tracking.
  • Use radiographs including weight-bearing and skyline views to assess implant and alignment.
