Clinical Report: Knee sepsis may be rare across tibial fracture care

Overview

Acute knee sepsis is infrequent following intramedullary nailing of open tibial shaft fractures, with a rate of 0.7% observed in a cohort study. The study compared intra-articular and extra-articular approaches, finding no statistically significant differences in sepsis rates or other complications.

Background

Understanding the risk of acute knee sepsis in patients undergoing intramedullary nailing for tibial fractures is crucial for surgical decision-making and patient management. The findings contribute to the existing literature on infection rates and surgical outcomes in orthopedic trauma.

Data Highlights

Key Findings

• Acute knee sepsis occurred in 0.7% of fractures analyzed (n=2).
• Intra-articular nailing had a knee sepsis rate of 1.1%, while extra-articular nailing had a rate of 0.5%.
• Deep infection rates were 9% for both intra-articular and extra-articular approaches.
• Superficial infection rates were 4% for intra-articular and 5% for extra-articular approaches.
• The study was underpowered to determine the relative risk of sepsis between the two approaches.
• Both cases of knee sepsis were diagnosed approximately 2 months post-surgery and involved methicillin-susceptible Staphylococcus aureus.

Clinical Implications

Surgeons should be aware of the low but present risk of acute knee sepsis associated with both intra-articular and extra-articular nailing techniques. This information may guide preoperative discussions and postoperative monitoring strategies.

Conclusion

The study highlights the rarity of acute knee sepsis following intramedullary nailing for open tibial fractures, emphasizing the need for continued vigilance in infection prevention.
