A new tendon repair design incorporating a mesh sleeve was, together with a new epitendinal suture technique (cross-stitch), tested biomechanically on sheep tendons. The mean breaking strength with a 6-0 suture was 103 N for the mesh sleeve repair and 63 N for the cross-stitch alone, both significantly greater than the 48 N recorded for the modified Kessler repair performed with a 4-0 polyester suture and reinforced with a circumferential conventional 6-0 epitendinal stitch. The cross-stitch grasp was 117% stronger than the conventional epitendinal grasp reinforced by a core stitch. The new techniques effectively prevented the large gaps that occurred in the modified Kessler repair.
一种采用网状套筒的新型肌腱修复设计，连同一种新的腱周缝合技术（十字缝合法），在羊肌腱上进行了生物力学测试。使用6-0缝线时，网状套筒修复的平均断裂强度为103 N，单纯十字缝合法为63 N，两者均显著高于使用4-0聚酯缝线并辅以传统6-0腱周缝合加强的改良凯斯勒修复术所记录的48 N。十字缝合法的抓持力比用核心缝线加强的传统腱周抓持力强117%。这些新技术有效防止了改良凯斯勒修复术中出现的大间隙。
