Evaluation of Negative Pressure Wound Therapy versus Dermabond Closure Over Orthopedic Incisions in the Hip and Knee. Texas Orthopaedic Journal


Introduction: Dermabond (DB) and negative pressure wound therapy (NPWT) have been shown to reduce the risk of postoperative infection in total joint arthroplasty. DB works well as a barrier to bacteria but may contribute to seroma formation and wound complications. NPWT can potentially decrease postoperative seroma formation and improve outcomes.

Methods: Four hundred twenty two patients with total hip or knee arthroplasty performed over a 2-year period were retrospectively reviewed to evaluate postoperative wound complications in patients treated with NPWT versus DB. The NPWT group showed 80% of patients did not have wound complications versus 68% in the DB group (p=0.03).

Results: There was a trend towards fewer patients requiring a return to the operating room in the NPWT group, but this did not achieve statistical significance (p=0.52).

Discussion: NPWT used in total joint arthroplasty over incisions of the hip and knee appears to decrease complications associated with surgical wound healing and may lower the chances of return to the operating room.
