Trial Summary

What is the purpose of this trial?

Interventional study exploring surgical site complication occurrences in high-risk revision patients undergoing TKA or THA using NPWT.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial investigators.

What data supports the effectiveness of the treatment Avance Solo Negative Pressure Wound Therapy for knee and hip replacement?

Research shows that negative pressure wound therapy (NPWT), like Avance Solo, helps wounds heal by using a vacuum to remove fluid and increase blood flow. It's been used successfully to prevent infections and complications in surgeries, including hip replacements and lower extremity fractures, suggesting it could be effective for knee and hip replacements too. ^{1 2 3 4 5}

Is Negative Pressure Wound Therapy safe for knee and hip replacement surgeries?

Negative Pressure Wound Therapy (NPWT) is generally safe, but it may cause more blisters in patients after total knee arthroplasty. It helps reduce superficial surgical site infections, and no significant differences in total complications were found compared to standard treatments. ^{1 2 3 6 7}

How is the Avance Solo Negative Pressure Wound Therapy treatment different from other treatments for knee and hip replacement?

The Avance Solo Negative Pressure Wound Therapy is unique because it is a portable, single-use system that allows patients to continue their treatment at home, promoting mobility and freedom while reducing hospital stay. It uses a vacuum dressing to help wounds heal by drawing out fluid and increasing blood flow, and it includes Safetac® adhesive technology to minimize pain during dressing changes. ^{1 2 3 5 8}

Findings from Research

In a pilot study involving 70 patients undergoing elective hip arthroplasty, negative-pressure wound therapy (NPWT) showed a slight reduction in surgical site infection (SSI) rates compared to standard dressings, but the difference was not statistically significant (2 vs 3 infections).

However, patients using NPWT experienced a higher rate of postoperative wound complications, indicating that while NPWT may have some benefits, it could also lead to more issues, suggesting the need for a larger trial to better assess its efficacy.

Use of Negative-Pressure Wound Dressings to Prevent Surgical Site Complications After Primary Hip Arthroplasty: A Pilot RCT. Gillespie, BM., Rickard, CM., Thalib, L., et al.[2022]

In a pilot study involving 60 patients undergoing major foot and ankle surgery, the use of a portable negative pressure wound therapy (NPWT) device resulted in a 7.5% rate of surgical site infections, which included both superficial and deep infections.

The incidence of surgical site infections with NPWT did not show a statistically significant reduction compared to a matched historical cohort, suggesting that while NPWT is feasible, it may not provide a clear advantage in preventing infections in this patient population.

In a study involving 11 patients with knee prosthesis infections, negative-pressure wound therapy effectively promoted healing by increasing blood flow and granulation tissue formation, which helped in managing septic complications.

The use of negative-pressure therapy allowed most patients to retain their knee implants, highlighting its potential as a valuable treatment option in orthopedic surgery for infections.

Negative pressure wound therapy (NPWT) shows a significant benefit over standard wound therapy (SWT) for wound closure in patients healing by secondary intention, based on a meta-analysis of 48 studies involving 4315 patients.

NPWT also significantly reduces the length of hospital stays by nearly 5 days compared to SWT, although no differences were found for other outcomes like mortality or adverse events.

In a study of 110 patients undergoing hip or knee revision surgery, negative pressure wound therapy (NPWT) showed a significantly lower ASEPSIS score (3.0) compared to standard dressing (5.1), indicating better wound healing outcomes in general.

While NPWT did not demonstrate a clinically relevant advantage for all patients, it was particularly beneficial for those with more than three risk factors for healing complications, showing a significant difference in ASEPSIS scores for this subgroup.
