Abstract

Objective: This study aimed to present a new modification of the modified Kessler tendon repair technique and share results of an animal study scrutinizing mainly the biomechanical properties and comparing it to other techniques.

Methods: Eighteen New Zealand rabbits were used and divided into 3 groups: 1 experiment and 2 control groups. Four-strand modified Kessler and 6-strand Tang repairs were used for the control groups. The new modification was used in the experiment group. Two surgeries were conducted 8 weeks apart, repairing 1 Achilles tendon in the first, repairing the contralateral tendon and harvesting specimens in the second. The repair times were recorded. In addition, biomechanical tests were conducted to determine mechanical strength.

Results: There was a statistically significant difference between the 3 groups in load-to-failure values for the strength after repair model, with the experiment group superior to the other 2 (P = .002; P < .05). Although there was a noticeable difference between the mean loadto- failure values of each group in the healing model, we could not demonstrate a statistically significant difference(P > .05). The new modification took significantly less time than the other 2 techniques (P = .001).

Conclusion: Our new modification was biomechanically stronger and faster than the other 2 techniques. The technique offers a new, suitable, practical option for human flexor tendon repair.

兔跟腱模型4股肌腱修复新技术:4股比6股好吗?

目的:本研究旨在提出一种改良的Kessler肌腱修复技术的新改良，并分享一项动物研究的结果，主要是审查生物力学性能并将其与其他技术进行比较。方法:选用新西兰兔18只，随机分为3组:1个试验组和2个对照组。对照组采用改良的4链Kessler修复和6链Tang修复。实验组采用新改良剂。两次手术间隔8周，第一次修复1条跟腱，第二次修复对侧跟腱，第二次采集标本。记录了维修时间。此外，还进行了生物力学试验以确定机械强度。结果:3组修复后强度模型的载荷失效值比较差异有统计学意义，实验组优于其他2组(P = 0.002;P < 0.05)。在愈合模型中，各组平均负荷失败值虽然有显著差异，但差异无统计学意义(P > 0.05)。与其他两种方法相比，新方法所花费的时间明显更短(P = .001)。结论:我们的新技术在生物力学上比其他两种技术更强、更快。该技术为人类屈肌腱修复提供了一种新的、合适的、实用的选择。

期刊介绍： Acta Orthopaedica et Traumatologica Turcica (AOTT) is an international, scientific, open access periodical published in accordance with independent, unbiased, and double-blinded peer-review principles. The journal is the official publication of the Turkish Association of Orthopaedics and Traumatology, and Turkish Society of Orthopaedics and Traumatology. It is published bimonthly in January, March, May, July, September, and November. The publication language of the journal is English. The aim of the journal is to publish original studies of the highest scientific and clinical value in orthopedics, traumatology, and related disciplines. The scope of the journal includes but not limited to diagnostic, treatment, and prevention methods related to orthopedics and traumatology. Acta Orthopaedica et Traumatologica Turcica publishes clinical and basic research articles, case reports, personal clinical and technical notes, systematic reviews and meta-analyses and letters to the Editor. Proceedings of scientific meetings are also considered for publication. The target audience of the journal includes healthcare professionals, physicians, and researchers who are interested or working in orthopedics and traumatology field, and related disciplines.
