The study's primary objective is to compare the following parameters between wound closure following primary TKA with and without supplement tissue adhesive (Leukosan®):
- Detailed Description
Prolonged wound drainage following total joint replacement surgery has been shown to be a predictor of Periprosthetic Joint Infection (PJI) 1-3. Several studies have highlighted this subject, and estimates of the risk of postoperative infection range from 1.3% to 50% among patients with persistent wound drainage 4. Such infections can be one of the most challenging complications following joint replacement surgery and is one of the leading causes of revision surgery following primary hip and knee arthroplasty 5,6.
Several patient-related factors have been associated with delayed wound healing and increased risk of infection following joint replacement surgery. Obesity 4,7, diabetes 8, smoking 9,10 and autoimmune disease 11 have been shown to have a detrimental effect on wound healing. Recently there has also been reports that patients with hypertension 12 have impaired wound healing following total hip arthroplasty (THA) and total knee arthroplasty (TKA).
Surgery related factors such as surgical approach, pneumatic tourniquet time and use of peri-articular local anesthesia have also been shown to have an effect on postoperative wound oozing 9,13.
Finally, several pharmacological factors, such as thromboembolic chemoprophylaxis 4, steroid treatment 9,14 and possibly statins 15,16 might also influence wound healing.
In recent years tissue adhesives for wound closure have been introduced as a replacement or a supplement to conventional closure techniques. Currently very few studies investigate the effect of such tissue adhesives in Total Knee Arthroplasty, and high quality randomized controlled trials (RCT) are lacking.
In this project we wish to:
Evaluate the effect of supplemental wound closure using a high viscosity tissue adhaesive (Leukosan®) in primary TKA with respect to postoperative wound drainage and wound healing.
This project is carried out as a randomized single-blinded controlled trial, in which the clinical outcomes after wound closure following primary bilateral simultaneous TKA with either 1) standard 3-layer closure methods with skin staples or 2) 3-layer closure methods with skin staples supplemented with tissue adhesive (Leukosan®) are compared.
After written informed consent is obtained patients scheduled for a primary bilateral simultaneous TKA will be enrolled in this study and left knee will be randomized to receive either 1) standard 3-layer closure methods with skin staples or 2) 3-layer closure methods with skin staples supplemented with tissue adhesive (Leukosan®), with the opposite treatment on the contralateral knee. All patients will receive AGC total knee prosthesis in both knees (department standard). The standard 3-layer closure consist of: size 2 coated VICRYL® Plus Antibacterial suture for capsule closure, size 2-0 coated VICRYL® Plus Antibacterial suture for subcutaneous tissue closure and stainless steel staples using PROXIMATE® Fixed-Head stapler for cutaneous closure. Wound oozing will be assessed by project nurses during postoperative day 1-3 as well as patient reported wound oozing on postoperative day 3-21. Wound healing will be assessed using ASEPSIS 17,18 score 3 weeks postoperatively.
Range of motion (ROM) will also be recorded at 3 months postoperatively. Allocation of the participants to one of the two treatment groups is done intraoperatively after initial incision has been made. Participants as well as the research coordinator handling the collected questionnaires postoperatively and evaluating wound healing are all unaware of which method was used for skin closure.
Recruitment of participants to this project is expected to begin in September 2015 or as soon as permission from the Regional Ethics Committee and the Danish Data Protections Agency is obtained. A total of 30 participants are to be included at our institution. Recruitment is expected completed after a maximum period of 1.5 years. The project is expected to be completed 1 year after recruitment of the last participant (2018).

Group Intervention Description Additional tissue adhaesive tissue adhesive (Leukosan®) The standard 3-layer closure is performed using: 1) size 2 coated VICRYL® Plus Antibacterial suture for capsule closure 2) size 2-0 coated VICRYL® Plus Antibacterial suture for subcutaneous tissue closure and 3) stainless steel stables using PROXIMATE® Fixed-Head stapler for cutaneous closure. tissue adhesive (Leukosan®) is applied on top of the staples according to manufacturer instructions. One layer (one tube) of tissue adhesive is applied following air-drying for 30 seconds, followed by a placement of a second layer with a second layer (one tube), and a second air-drying period of 60 seconds
- Primary Outcome Measures
Name Time Method Wound discharge during stay 3 days post op The wound will be defined as actively oozing, if the standard bandage Mepilex Border Post-op®, is soaked to the border. Bandages soaked to the border will be replaced. Number of replaced bandages for each knee will be recorded.
- Secondary Outcome Measures
Name Time Method ASEPSIS score 3 weeks post op Wound healing score
