Summary
Aseptic complications after total knee arthroplasty are decreasing due to improved techniques and management. Extensor mechanism dysfunction remains the most common issue, highlighting the importance of prevention.
Area of Science:
- Orthopedic surgery
- Biomedical engineering
Background:
- Aseptic complications following total knee arthroplasty (TKA) have historically impacted patient outcomes.
- Recent years have seen a decline in the incidence of these complications.
Purpose of the Study:
- To review the current landscape of aseptic complications after TKA.
- To identify the most frequent and other significant sources of dysfunction.
- To emphasize the importance of complication prevention.
Main Methods:
- Literature review and analysis of recent trends in TKA complications.
- Categorization of common and less common aseptic complications.
- Discussion of contributing factors to complication reduction.
Main Results:
- Aseptic complications after TKA are less frequent compared to previous decades.
- Extensor mechanism dysfunction is the most common complication and a leading cause for revision surgery.
- Other less frequent but significant complications include mechanical wear, instability, fracture, and stiffness.
Conclusions:
- Advances in surgical techniques, implant design, and perioperative care have reduced TKA complications.
- Preventing complications is the most effective strategy to ensure favorable outcomes after TKA.
