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

Abstract

Background: The study focusing on the tissue adhesive in total knee arthroplasty (TKA) was rare. This study aimed to evaluate the clinical outcomes and economic costs of tissue adhesive when acting as the adjunct to standard incision closure in TKA. Patients and Methods: From September 2019 to November 2019, we prospectively enrolled the consecutive patients who underwent simultaneous bilateral TKA in our institute. The allocation using the tissue adhesive was done after the subcuticular suture in right knee first and another method was applied in the left knee automatically. The patients' demographics, length of stay (LOS), times of dressing changes and incision-related cost, range of motion (ROM), incision-related complications and incision evaluation scores were recorded. Results: Thirty-two patients were enrolled in this study and followed at two months after surgery. In the knees of tissue adhesive, the times of dressing change and patient scar assessment scores (PSAS) were significantly less than those standard skin closure (p=0.000; p=0.003). Although there were no significant differences of the delayed discharge, incision-related cost, ROM, incision-related complications and Vancouver scar score (VSS) between two groups, 65.6% (21/32) patients preferred the tissue adhesive and only 15.6% (5/ 32) patients preferred the standard incision closure. Conclusion: Tissue adhesive could effectively reduce postoperative wound drainage and improve patients' satisfaction rate with no difference in medical costs and ROM in TKA. The application of tissue adhesive and subcuticular sutures might be one safe and convenient method of skin closure in TKA.

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

“…The scoring system, thus reflects that there is no significant statistical difference in the score between the two groups. Kong et al ( 12 ) and Langlois et al ( 28 ) conducted the same evaluation and found the same results.…”

“…Patients who were unable to complete the regular follow-up, had skin diseases, like psoriasis or eczema, or other serious systemic diseases, had previous open knee surgery on either knee, had previous major trauma to either knee resulting in deformity or scarring or had allergies to skin adhesives were excluded. According to relevant research ( 10 , 12 ), a minimum of 30 participants was required for each group according to a power analysis (alpha = 0.05, beta = 0.2).…”
