The enrolled patients were divided into two groups according to the suture mode, with 45 cases (group A) receiving closure of the deep tissue with a barbed suture and intradermal suture of the incision with another barbed suture and 49 cases (group B) receiving closure of the deep tissue with absorbable suture and interrupted suture of the incision with nonabsorbable suture. Further comparisons were performed regarding incision length, suture time, postoperative incision complications, Hollander Wound Evaluation Score (HWES), Hospital for Special Surgery (HSS) knee score, American Knee Society (AKS) score, and Patient and Observer Scar Assessment Scale (POSAS). The clinical effects of the two suture modes in TKA and the patients’ aesthetic satisfaction with the incision were also evaluated at 2 weeks, 3 months and 6 months after the operation.Results: Compared with group B, group A had higher HWES at 2 weeks after the operation (P < 0.05), shorter suture times (P < 0.05) and lower POSAS scores at 3 and 6 months after the operation (P < 0.05). However, no significant difference was observed between the two groups in incision length, complication rate, HSS or AKS scores (P > 0.05).Conclusion: Compared with the interrupted suture, the use of whole-layer barbed suture for incision closure after TKA has the advantages of a safe and effective outcome, short operation time, high cosmesis degree of the wound scar and high patient satisfaction.Keywords: barbed suture, knee arthroplasty, interrupted suture, aesthetic satisfaction of incision
