What this trial studies

This clinical trial aims to compare the effectiveness of two different durations of negative pressure wound therapy (NPWT) dressings in patients undergoing revision hip and knee surgeries. Eligible participants will be randomly assigned to receive either a 7-day or a 14-day NPWT dressing treatment. The study will include a total of 164 patients, with 82 in each surgical cohort, to evaluate which duration is more effective in promoting wound healing. The trial is conducted at a single site, ensuring close monitoring and follow-up of all participants.

Who should consider this trial

Good fit: Ideal candidates are adults over 18 years old requiring aseptic revision hip or knee surgery.

Not a fit: Patients with infections or contraindications to NPWT dressings will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could optimize wound healing protocols, potentially reducing complications and improving recovery times for patients undergoing revision surgeries.

How similar studies have performed: Previous studies have shown benefits of NPWT in wound healing, but this specific comparison of treatment durations is novel.

Inclusion Criteria:

* Subjects must be over the age of 18 years.
* Participants undergoing aseptic revision hip or aseptic revision knee surgery procedure (a single stage revision procedure).
* Participants must be willing and be able to make all the required study visits to be seen by the research team at the Outpatients department at RJAH.
