Abstract
Orthopaedic implant removal is considered a sterile procedure, but the current literature suggests it is associated with around a 20% Surgical Site Infection (SSI) rate. The use of antibiotic prophylaxis is still ambiguous and contentious. Taking into consideration this issue we conducted a meta-analysis for the use of antibiotic prophylaxis in orthopaedic implant removal surgery.
Objectives: To determine whether or not antibiotic prophylaxis benefits orthopaedic implant removal surgeries.
Methods: Electronic and printed sources were searched up to February 2021 for randomised controlled trials (RCTs) using antibiotic prophylaxis and a control group. Data from eligible studies were pooled for the following outcomes: overall, superficial, and deep surgical site infection (SSI). Pooled odds ratios with a 95% confidence interval (CI) were calculated using Mantel Haenszel fixed-effect model preferentially.
Results: Two studies, including 766 patients were included in this meta-analysis. Heterogeneity was not statistically significant between the studies. There was no significant difference in the incidence of overall SSI in cefazolin and normal saline (NS) groups (Pooled OR 0.79; 95% CI 0.53- 1.17). In subgroup analysis, antibiotic prophylaxis showed statistically significant improvement for deep SSI (Pooled OR 0.20; 95% CI 0.06-0.70).
Conclusion: Overall incidence of SSI is not reduced after the administration of antibiotic prophylaxis one hour before removal of orthopaedic implants.
