Summary
Patellar instability after total knee replacement (TKA) can cause significant complications. Early identification of the cause, such as component malposition, is crucial for successful surgical management and improved patient outcomes.
Area of Science:
- Orthopedic Surgery
- Biomedical Engineering
Background:
- Patella instability and maltracking are significant complications following total knee arthroplasty (TKA).
- These complications can lead to poor patient outcomes and early device failure, with an incidence ranging from 1% to 20%.
- Anterior knee pain is a key indicator of post-operative patella maltracking.
