Summary
Computer Navigated knee Arthroplasty pin sites can cause complications. This study found minimal complications, particularly fewer peri-prosthetic fractures, using specific pin insertion techniques.
Area of Science:
- Orthopedic Surgery
- Biomedical Engineering
Background:
- Intra-osseous pin sites in Computer Navigated knee Arthroplasty (CKNA) are associated with risks such as infection and fracture.
- Minimizing these complications is crucial for improving surgical outcomes in CKNA.
Purpose of the Study:
- To report complication rates from a single-surgeon series of CKNA.
- To evaluate techniques for reducing pin site complications.
Main Methods:
- Retrospective analysis of 321 CKNA patients (2009-2013).
- Detailed review of pin insertion techniques, including uni-cortical drilling.
Main Results:
- One superficial pin site infection occurred.
- No major complications were observed during a mean 31-month follow-up.
- Uni-cortical drilling was associated with lower peri-prosthetic fracture rates compared to bicortical drilling.
Conclusions:
- Meticulous attention to pin insertion technique minimizes minor and major complications in CKNA.
- Uni-cortical drilling may be a beneficial technique for reducing peri-prosthetic fractures.
