About this study

Official title: Efficacy of Wound Care and Reduction of Wound Complications by Use of AQUACEL® Ag Surgical Dressing in Minimally Invasive Total Knee Arthroplasty:A Prospective, Randomized Controlled Study

The investigators hypothesized that AQUACEL® Ag Surgical dressing would have a significant improvement in the efficacy of wound care and wound complications compared with traditional Sofra-Tulle® dressings after minimally invasive total knee arthroplasty (MIS-TKA).

Read the detailed description

Traditional adhesive dressing (Mepore®; Mölnlycke Health Care) for low limb arthroplasty wounds had blistering up to 26%. The jubilee dressing, which consisted of a highly absorbent Hydrofiber inner layer and (Aquacel; ConvaTec Inc.) and a viscoelastic hydrocolloid outer layer (DuoDERM Extra Thin; ConvaTec Inc.), was introduced for lower limb arthroplasty wounds with lower blistering rate (2% vs. 18%) and lower surgical site infection (1% vs. 3%) compared to traditional adhesive dressing. A new modern dressing regime (Aquacel Ag Surgical dressing; ConvaTec Inc.) also reported longer wear time, less dressing change and less blistering.

In our institution, the standard wound care after TKA was an antimicrobial dressing (Sofra-Tulle®; Royal Chem. \& Pharm. Co., Kaohsiung, Taiwan) in the inner layer and gauzes in the outer layer.

The investigators hypothesized that AQUACEL® Ag Surgical dressing would have a significant improvement in the efficacy of wound care and wound complications compared with traditional Sofra-Tulle® dressings after MIS-TKA.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • AQUACEL® Ag Surgical dressing (study group)Other

    The AQUACEL® Ag Surgical dressing was applied to the wound in the operating theater by the surgeon. Clinical indications for removal of the AQUACEL® Ag Surgical dressing were leakage from the dressing beyond the hydrocolloid exterior layer and more than a 50% saturation of the Hydrofiber® inner layer10. If there were no indications to change the dressing, it was changed at the day of discharge usually the 4th or 5th postoperative day (POD) and remained cover of the wound for 7 days except for exudate across the dressing.

  • Sofra-Tulle® dressing (control group)Other

    The Sofra-Tulle® dressing was applied to the wound in the operating theater by the surgeon. The Sofra-Tulle® dressing was routinely changed at a daily basis. If there were strikethrough on the gauze, the nursing staff would proceed the dressing change automatically between the daily routine. After discharge from the hospital, the family who had been taught well to do this job during the patient's stay in the hospital conducted the daily dressing change.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Wound Care Efficacy

    Wear time, No. of dressing change,

    Measured: an expected average of 5 days at the duration of hospital stay

  2. Number of Participants with Adverse Events

    Blister formation, wound erythema, discharge and necrosis

    Measured: Three months after surgery

  3. ASEPSIS score

    Additional treatment, Serous discharge, Erythema, Purulent exudate, Separation of deep tissue, Isolation of bacteria and Stay as inpatient

    Measured: 2 weeks after surgery

  4. Surgical site infection (SSI)

    Superficial or deep infection of the wound

    Measured: Three months after surgery

Secondary outcomes (3)
  1. Pain Scores on the Visual Analog Scale

    overall pain management, and removal when using the dressings

    Measured: two weeks after surgery

  2. Comfort scale

    The dressing is comfort in use and ease of application (excellent, good, fair or poor)

    Measured: two weeks after surgery

  3. Ease scale

    The dressing is ease of application and removal (excellent, good, fair or poor)

    Measured: two weeks after surgery

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing AQUACEL® Ag Surgical dressing (study group) in people with Postoperative Complication, run by Chang Gung Memorial Hospital.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 15 May 2015. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Wound Care Efficacy (time frame: an expected average of 5 days at the duration of hospital stay). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 May 2015.
