Intrawound Vancomycin Powder Reduces Early Prosthetic Joint Infections in Revision Hip and Knee Arthroplasty.
Intrawound vancomycin powder has shown efficacy and safety in decreasing postoperative spine infections, but its use in arthroplasty has not been well established. The purpose of this study was to compare the rate of early prosthetic joint infections (PJI) with and without the use of intrawound vancomycin powder during joint arthroplasty. A retrospective cohort of all patients who underwent primary or revision hip or knee arthroplasty by two surgeons over a two-year period at a single hospital system was evaluated. The control group received standard systemic prophylaxis only, whereas the treatment group received 1 g of vancomycin powder in the surgical wound in addition to systemic prophylaxis. A statistically significant decrease in the overall PJI rate was found in the treatment group (4/816=0.49%) compared to the control group (13/824=1.57%; p=0.0479). Subgroup analysis demonstrated a trend toward fewer PJIs in the vancomycin group, however, only the revision procedures showed a statistically significant reduction in early PJIs after the initiation of vancomycin (7/180=3.89% to 0/134=0%; p=0.0217). The use of intrawound vancomycin powder was associated with a significant reduction in the overall incidence of early PJIs following joint arthroplasty, however, only the revision procedures demonstrated a significant reduction in the rate of early PJIs.
