Watertight capsular closure in knee arthro- plasty is desirable in order to achieve a good functional outcome. Barbed knotless sutures are being increasingly used in wound closure following knee arthroplasty. The prior studies have compared barbed sutures with either VICRYL® or Ethibond for closure, while none had compared all the three in a single setting in terms of closure time, needle stick injuries, postoperative complications, and functional outcome.
One hundred and forty-three subjects of unilateral knee arthroplasty were screened for eligibility in the prospective randomized controlled trial. One hundred and twenty patients fulfilled the inclusion criteria and were randomized into three groups to undergo capsular closure with barbed sutures, VICRYL, or Ethibond.
The wound closure was fastest with barbed su- tures followed by VICRYL and Ethibond (10.4 ± 4.1; 15.4 ± 4.7; 17.2 ± 3.8 minutes; p < 0.001). There were seven needle stick injuries in the Ethibond group followed by three in the VICRYL group and none in the barbed suture group. The Knee Society Scores and wound related complications were comparable in all the three groups.
Barbed suture, VICRYL, and Ethibond are equally good in the capsular closure following knee arthro- plasty. The faster wound closure time achieved may not be clinically relevant in the short term.
膝关节关节成形术中的水密囊封闭是理想的，以达到良好的功能结果。带倒钩的无结缝线越来越多地用于膝关节置换术后的伤口闭合。先前的研究比较了带倒钩缝线与 VICRYL®或 Ethibond 在闭合方面的效果，而没有一项研究在单一设置中比较了这三种缝线在闭合时间、针刺伤、术后并发症和功能结果方面的效果。
143 名单侧膝关节置换术患者被筛选出符合前瞻性随机对照试验的条件。120 名患者符合纳入标准，并随机分为三组，分别采用带倒钩缝线、VICRYL 或 Ethibond 进行囊袋封闭。
带倒钩缝线的伤口闭合最快，其次是 VICRYL 和 Ethibond（10.4 ± 4.1；15.4 ± 4.7；17.2 ± 3.8 分钟；p < 0.001）。Ethibond 组有 7 例针刺伤，VICRYL 组有 3 例，带倒钩缝线组无针刺伤。三组的膝关节学会评分和伤口相关并发症相当。
带倒钩缝线、VICRYL 和 Ethibond 在膝关节关节成形术后的囊袋封闭中同样有效。更快的伤口闭合时间在短期内可能没有临床意义。
