Clinical Trial Summary

About 500 total ankle prostheses are implanted each year in France. Wound healing issues are the most common complications after Total Ankle Arthroplasty (TAA). In 2010, a French retrospective study observed a wound infection rate of 8% among 592 prostheses implanted. Wound infection rate can vary up to 28% from the data available in the literature. Delayed wound healing is a known risk factor of surgical site infection (SSI). Even if it remains a rare event, its consequences for the patient can be severe and lead to removal and/or replacement of the prosthesis, arthrodesis, or transtibial amputation. Negative Pressure Wound Therapy (NPWT) is an adjuvant therapy for wound management and healing: it delivers a controlled negative pressure (sub-atmospheric) applied topically onto the wound from a vacuum pump. The wound is filled with wound filler and sealed with an airtight adhesive drape. It allows creating a moist wound environment, removing exudate, and reducing edema and risk of infection. Incisional NPWT can accelerate wound healing regardless of the surgery performed, including orthopedics. A retrospective study compared the incidence of healing complications after TAA between the administration of the NPWT PICO™ (Smith&Nephew) and the standard of care of postoperative wounds in 74 patients. A significant reduction of wound healing issues (3% vs. 24%, respectively; p=0.004) and a non-significant reduction of SSI (3% vs. 8%, respectively) were observed. To the investigator knowledge, no randomized study has been conducted to assess the efficacy of the NPWT PICO™ for postoperative wound healing after TAA: Investigators propose to set up this study to obtain a high level of evidence in this population and investigators assume that the use of the PICO™ system after TAA would reduce delayed wound healing compared to the standard of care with conventional dressings.

Outcome

Type Measure Description Time frame Safety issue
Primary Number of days from suture removal (i.e. day 21 after surgery) to achieve complete wound healing defined as: no visible exudate on protection dressing; and no blister; and no necrosis; and no wound dehiscence. Up to 12 months after TAA
Secondary Rate of technical failures of the PICO™ device, and type of failure: device failure, non-hermetic dressing, other. baseline to postoperative day 7
Secondary Number and type of adverse effects related to the PICO™ device. baseline to postoperative day 7
Secondary Rate of wound healing complications: presence of exudate; blister; necrosis; wound dehiscence. postoperative day 21, postoperative week 6, postoperative months 4 and 12.
Secondary Rate of surgical site infection (superficial, deep or of a surgical site other than the incision site). postoperative day 30 to postoperative month 12.
Secondary Rate of surgical revision for wound healing complications defined by: mechanical debridement; surgical debridement; flap surgery and skin graft. Baseline to postoperative month 12.
Secondary Incremental Cost-Effectiveness Ratio (ICER) between the two dressing strategies. A cost-effectiveness analysis comparing the strategy using PICO device and the one using only conventional dressing will be performed during 12 months after surgery, from the perspectives of the French hospital and French health insurance system; the result will be expressed in terms of cost per complication avoided. Up to 12 months after TAA.
