Exploring surgical site infections in high-risk knee and hip revision patients

An Interventional Study to Explore the Occurrence of Surgical Site Complications in High-risk Patients After Revision of Total Hip or Knee Joint Arthroplasty Receiving Closed Incision Negative Pressure Wound Therapy.

Not applicable Interventional Molnlycke Health Care AB · NCT06661473

This study is testing if a special wound therapy can help high-risk patients who have knee or hip surgery avoid infections after their operation.

What this trial studies

This interventional study investigates the occurrence of surgical site complications in patients undergoing elective unilateral revision total knee arthroplasty (TKA) or total hip arthroplasty (THA) who are considered high risk for such complications. The study utilizes Avance Solo Negative Pressure Wound Therapy (NPWT) to manage surgical wounds post-operatively. Participants must be able to understand and operate the NPWT system at home, and the study focuses on patients with specific eligibility criteria to ensure safety and efficacy. The goal is to assess the effectiveness of NPWT in reducing infection rates in this vulnerable patient population.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older who are undergoing elective unilateral revision TKA or THA and are deemed high risk for surgical wound complications.

Not a fit: Patients requiring emergency surgery, those with active infections, or those needing bilateral revision surgeries may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could significantly reduce the incidence of surgical site infections in high-risk patients undergoing revision arthroplasty.

How similar studies have performed: Other studies utilizing negative pressure wound therapy have shown promising results in reducing surgical site infections, indicating potential success for this approach.

2. Multiple Incision Approach at the time of surgery (alternative approach from primary surgery using 1 incision is permitted)
3. Patients requiring bilateral revision total hip or knee arthroplasty surgery
4. Active infections of the offending joint.

10. Patient with incisions \> 25cm in length or type of incisions that cannot be sufficiently covered by Avance Solo Border dressing (i.e., the wound pad does not overlap the edges of the incision by at least 1.5 cm as per the IFU)
11. Use of surgical glue as part of incisional closure method
12. Patients who in the opinion of the investigator may not complete or comply with follow up treatment for any reason
13. Patients participating in ongoing clinical investigations, or during the past 30 days, that may impact the outcome of this investigation based on the judgement of the investigator.
14. Any clinically significant condition that, in the investigator's opinion, would significantly impair the subject's ability to comply with the study
