Incisional negative pressure wound therapy (INPWT) has been used for high-risk surgery across specialties but has yet to be utilised for revision hip and knee surgery. Between 2013 and 2014, patients who underwent revision arthroplasty by the senior author were identified. 36 (9 hips and 27 knees) operations in 36 patients identified 18 (8 male, median age 77 (61–86)) who received standard dressing and 18 (12 male, median age 67 (58–81)) who received single use portable INPWT dressings (4 hips, 14 knees). Wound complications were seen in 3 (2 knees) from the standard group and 1 (hip) in the INPWT group (). There was no statistical difference in age or gender between groups. Risk factors (BMI > 30, smoking, and diabetes) were identified in 9 patients, median ASA 3, in the standard group and 10 patients, median ASA 2, in the INPWT group. There were no dressing related complications. This is the first study of INPWT with a low pressure single use 80 mmHg dressing with revision arthroplasty. This initial study showed a threefold decrease in wound complication in the INPWT group and that INPWT is a safe alternative to standard dressings.
