A Prospective, Randomized and Controlled Study on Tissue Adhesive for Skin Incision in Total Knee Arthroplasty

2-Octyl-Cyanoacrylate Mesh Dressings for Total Joint Arthroplasty: Dressing Design Influences Risks of Wound Complications

INTRODUCTION

Recent liquid adhesive skin closure systems with a mesh patch and a 2-octyl cyanoacrylate liquid formula have shown promising results in total joint arthroplasty (TJA). Chemical accelerators are typically included to promote the rapid polymerization of 2-octyl cyanoacrylate. The goal of the study is to distinguish designs and wound complication differences between two similar systems.

METHODOLOGY

An eighteen-week retrospective study was conducted from July to December 2023, including 207 total hip arthroplasty (THA) and 212 total knee arthroplasty (TKA) cases from four attending surgeons at one institution that used one of two dressing designs. Both dressings had a 2-octyl cyanoacrylate liquid adhesive formula that applied topically to a polyester-based mesh overlaying the wound. Mesh A (used in 274 cases) included an accelerator, a quaternary ammonium salt, on the mesh patch, whereas Mesh B (used in 145 cases) included a similar accelerator within the adhesive applicator.

RESULTS

Wound complications (3.2 versus 7.6%; X2 = 3.86; df = 1; P = 0.049), early periprosthetic joint infections (PJI) (0 versus 2.8%; X2 = 7.63; df = 1; P = 0.006), and 90-day reoperations for wound complications (0.4 versus 3.4%; X2 = 6.39; df = 1; P = 0.011) were significantly lower in patients who received Mesh A versus B, respectively. There was no difference in superficial surgical site infections (SSI) (0.7 versus 0%; X2 = 1.06; df = 1; P = 0.302) or allergy rates (3.3 versus 4.1%; X2 = 0.12; df = 1; P = 0.655) between Mesh A and B.

CONCLUSION

We observed significantly different performance in wound complications, early postoperative PJI, and 90-day reoperation between the two designs. Having the accelerator in the applicator rather than on the mesh patch, may lead to premature polymerization before bonding appropriately with the mesh to create the desired wound closure and seal.

Optimal Method of Skin Wound Management for Total Knee Arthroplasty: A Systematic Review and Meta-Analysis

Skin closure for total knee arthroplasty (TKA) typically focuses on promoting optimal healing, while preventing wound complications and infection, allowing for functionality and immediate ambulation, and providing for excellent cosmesis. In this systematic review and meta-analysis of the literature, we will focus on closure of the skin. Specifically, we assessed: (1) wound complication risk of different techniques and (2) closing time of different sutures/techniques. There were 20 reports on infection risk and closing time. Meta-analyses focused on the qualifying studies for closing time and wound complication risk reports were also performed. These studies (378 patients) demonstrated overall lower wound complication risks with the use of barbed compared with traditional sutures (3% vs. 6%, p < 0.05). The subsequent meta-analysis included 749 patients demonstrating overall significant closing time reductions of a mean of 7 minutes with the use of barbed sutures (p < 0.05). Therefore, multiple recent reports suggest superior outcomes and faster results when using barbed sutures for TKA skin closure.

A New Dressing System for Wound in Enhanced-Recovery Total Hip Arthroplasty: A Randomized and Controlled Trial

BACKGROUND

Currently, there is a paucity of recommendations in regards to dressing selection within the enhanced recovery after surgery protocol. We devised a new dressing system to accelerate the recovery after total hip arthroplasty (THA). We aimed to present our experience with this new dressing system as an adjunct to wound management in THA and to evaluate its performance.

METHODS

From September 2020 to August 2021, we prospectively enrolled 124 patients who underwent a primary THA. The patients were randomly assigned to the intervention (the new dressing system group) or the control (the traditional gauze dressing) group. The primary outcome measures of this study were numbers of dressing changes, postoperative lengths of stay, wound scores including the Stony Brook Scar Evaluation Scale and ASEPSIS scores and wound-related complications. The secondary outcomes include satisfaction scores, dressing-related costs, and pain and functional recovery scores.

RESULTS

The intervention group numbers of dressing changes and postoperative lengths of stay were significantly less than the control group (P < .001, P < .001). During the one-month follow-up, the Stony Brook Scar Evaluation Scale in the intervention group was significantly better than that in the control group (P < .001). The intervention group satisfaction was significantly higher than that in the control group (P < .001). There were no statistically significant differences between the two groups in terms of dressing-related costs and pain and function scores.

CONCLUSION

The new dressing system could significantly reduce the number of dressing changes and postoperative lengths of stay and increase patient satisfaction scores, which can be an ideal adjunct to wound management in enhanced-recovery THA.

A New Dressing System Reduces the Number of Dressing Changes in the Primary Total Knee Arthroplasty: A Randomized Controlled Trial

Purpose

We devised a novel dressing system to accelerate the recovery after total knee arthroplasty (TKA). The purpose of this study was to assess the clinical outcomes and economic expenses of the new dressing system.

Methods

In this randomized and controlled trial, we enrolled 98 patients who underwent the first unilateral TKA between September 2020 and June 2021. The patients were randomly assigned to one of two groups: the intervention (the new dressing system group) or the control (the traditional gauze dressing) group. We gathered and evaluated patient data including age, gender, body mass index, surgical side, number of dressing changes, post-operative hospital stay, dressing-related expense, satisfaction, pain and function scores, wound scores and wound-related complications.

Results

The number of dressing changes and post-operative hospital stay in the intervention group were significantly less than in the control group (p = 0.000, p = 0.002). Satisfaction in the intervention group was significantly higher than in the control group's (p = 0.000). There were no significant differences between the two groups in dressing-related expense, pain and function scores. During the one month follow-up, the intervention group's Stony Brook Scar Evaluation Scale (SBSES) was considerably higher than the control group's (p = 0.012).

Conclusion

The new dressing system can reduce the number of dressing changes and post-operative hospital stays while increasing patient satisfaction with no difference in medical costs in TKA. This wound dressing system has potential for application in TKA.

No Additional Benefits of Tissue Adhesives for Skin Closure in Total Joint Arthroplasty: A Systematic Review and Meta-Analysis of Randomized Controlled Trials

BACKGROUND

This systematic review is aimed to compare the performance of tissue adhesives (TA) as an adjunct or closure method with traditional wound closure methods for cutaneous closure in arthroplasty and evaluate whether they have any added benefits in terms of decreasing wound complications and increasing postoperative patient satisfaction.

METHODS

Cochrane Library, PubMed, and EMBASE were searched until February 2021. Randomized controlled trials (RCTs) comparing outcomes of TA with emphasis on skin closure time, in-hospital stay, complication rates, cosmetic scoring systems, and patient satisfaction scores (PSS) compared to subcuticular sutures (SCS) and skin staples (ST) in arthroplasty. The quality of RCTs was assessed using the National Institutes of Health quality assessment tool.

RESULTS

Ten RCTs were included. The pooled and the subgroup analysis revealed no significant difference in the wound infection rates, discharge rates, dehiscence rates, and PSS between TA (as an adjunct or closure method) and SCS or ST. TA (as an adjunct or closure method) was significantly (P < .00001) associated with a longer time to closure compared to ST and a shorter time compared to SCS as a closure method. Length of stay was comparable in all groups.

CONCLUSION

Using TA in combination with subcuticular sutures or ST or as a cutaneous method of closure does not provide additional benefits in terms of decreased hospital stay, decreased infection rates, or wound discharge rates. The PSS and pain scores of the scars also appear to be comparable to standard wound closure methods. No clear conclusion could be drawn regarding cosmetic scoring systems, because of the paucity of data.
