Summary
Total knee arthroplasty (TKA) has seen fewer extensor mechanism complications due to surgical improvements. Most complications arise from surgical technique errors but are preventable with proper methods and component selection.
Area of Science:
- Orthopedic Surgery
- Biomedical Engineering
Background:
- Total knee arthroplasty (TKA) advancements have improved outcomes.
- Extensor mechanism complications remain a concern despite progress.
Purpose of the Study:
- To review extensor mechanism complications following TKA.
- To highlight the role of surgical technique in complication incidence.
Main Methods:
- Review of recent literature on TKA surgical techniques.
- Analysis of prosthetic design and instrumentation impact.
- Categorization of extensor mechanism complications.
Main Results:
- Improvements in TKA have reduced complication rates.
- Surgical technique errors are the primary cause of complications.
- Common complications include impingement, instability, and patellar issues.
Conclusions:
- Most extensor mechanism complications are preventable.
- Proper surgical technique and patellar component selection are crucial for TKA success.
