Wound closure in primary knee arthroplasty is important both for surgical success, by minimizing the risk of wound complications and infection, and for patient satisfaction with wound care and cosmesis. This article reports the use of a topical self-adhering, pressure-sensitive polyester mesh combined with 2-octyl cyanoacrylate adhesive for final skin closure of primary knee arthroplasty without external staples or sutures. During a 2.5-year period, 360 consecutive primary knee arthroplasty procedures (321 total knee arthroplasty procedures and 39 partial knee arthroplasty procedures) performed by 1 surgeon at 1 institution were reviewed. For all primary arthroplasty procedures, closure was performed with a standardized method. Final skin closure was performed with 2-octyl cyanoacrylate adhesive and polyester mesh. Patients returned at 6 weeks and 1 year postoperatively. The study found a 0.8% rate of superficial wound complications, no cases of dehiscence, no wound complications requiring operative irrigation and debridement, and no prosthetic joint infections. One patient had a reaction consistent with previously reported localized contact dermatitis that was believed to be related to the 2-octyl cyanoacrylate adhesive. In 2 cases, treatment with cephalexin was required, in 1 case for 2 small suture abscesses and in the other case for periincisional cellulitis. All wound complications resolved by 6 weeks. The results showed that 2-octyl cyanoacrylate adhesive and polyester mesh can be used successfully in the setting of primary knee arthroplasty for closure of high-tension knee arthroplasty wounds. This series found a 0.8% rate of superficial wound complications, no cases of dehiscence, and no infections. [Orthopedics. 2017; 40(5):e784-e787.].
