Periprosthetic Knee Infection Reinfection Rates Under Four Surgical Strategies

145 patients with periprosthetic knee infection were tracked for a median of 99 months to compare four surgical strategies. The dataset includes reinfection and re-revision rates, microbial profiles of recurrent infections, and infection-free prosthesis survival rates at 2 and 5 years. This retrospective observational study was conducted at a single centre between October 2012 and October 2022.

Use Cases

• Compare long-term reinfection rates based on the four surgical strategies (DAIR, one-stage, 1.5-stage, two-stage revision).
• Analyze infection recurrence patterns based on microbial profiles (relapse vs. new infection).
• Model infection-free prosthesis survival based on the provided cumulative rates at 2 and 5 years.

Strengths

• Includes data for 145 patients with a minimum follow-up of 2 years.
• Provides specific cumulative reinfection rates with 95% confidence intervals for each surgical strategy at 2 and 5 years.
• Distinguishes between relapse infections (same organism) and new infections (different organism).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is from a single centre, which may limit generalizability.
