Adhesive 2-octyl safe and effective wound closure technique for patients undergoing TKA: study

Good wound healing is critical to infection prophylaxis and satisfactory rehabilitation in Total Knee Arthroplasty (TKA). Currently, two techniques, i.e., barbed continuous subcuticular suture without skin adhesive or combined use skin adhesive (n-butyl-2) are being used for superficial wound closure of TKA. While a new skin adhesive (2-octyl) with self-adhesive mesh has been employed as an alternative to conventional surgical skin closure in TKA, its superiority, especially in reducing wound complications and improving wound cosmetic outcomes has not been investigated.

Liu et al conducted a study to compare 2-octyl, n-butyl-2, and no skin adhesive in terms of safety and efficacy in TKA superficial wound closure. It has been published in ‘Arthroplasty’ journal.

The authors conducted a multicenter, prospective, randomized controlled study in 105 patients undergoing primary TKA. Each patient’s knee was randomized to receive 2-octyl, n-butyl-2, or no skin adhesive skin closure with all using barbed continuous sutures in deep tissue. Wounds were followed 1, 3, 5 days, 2, 6 weeks, and 3 months after surgery. Wound discharge, complications, cosmetic outcomes, patient satisfaction, and wound-related costs were compared among these three methods.

Key findings of the study were:

• Wound discharge was less in 2-octyl group and n-butyl-2 group than in non-adhesive group at 1 day, with the discharge only being less in 2-octyl group than in the non-adhesive group at day 3 and day 5 days (P<0.05).

• There was no statistical difference in the incidence of other wound complications among the groups (P>0.05).

• The 2-octyl group achieved better cosmetic efects than the other two groups in 6 weeks and 3 months (P<0.05).

• Compared to the non-adhesive group, 2-octyl group scored higher in overall patient satisfaction score in 2 weeks and incurred lower costs (P<0.05).

The authors concluded that – “Skin closure in TKA using 2-octyl adhesive material showed superiority to no skin adhesive or n-butyl-2. It reduced wound discharge and improved cosmetic outcomes, without increasing wound complications. In addition, the use of 2-octyl could achieve excellent patient satisfaction and lowered costs compared to no skin adhesive. Our study demonstrated that the use of 2-octyl was a safe and effective as a wound closure technique in patients undergoing TKA.”
