Abstract：
OBJECTIVE: It is unclear which triceps tendon repair constructs and techniques produce the strongest biomechanical performance while minimizing the risk of gap formation and repair failure. We aimed to determine associations of construct and technique variables with the biomechanical strength of triceps tendon repairs. PubMed, Embase, Cochrane Library, Web of Science, Scopus, and ClinicalTrials.gov were systematically searched for peer-reviewed studies on biomechanical strength of triceps tendon repairs in human cadavers. 6 articles met the search criteria. Meta-regression was performed on the pooled dataset (123 specimens). Outcomes of interest included gap formation, failure mode, and ultimate failure load. Covariates were fixation type; number of implants; and number of sutures. Stratification by covariates was performed. We found no association between fixation type and ultimate failure load; however, suture anchor fixation was associated with less gap formation compared with transosseous direct repair (β = - 1.1; 95% confidence interval [CI]:- 2.2, - 0.04). A greater number of implants was associated with smaller gap formation (β = - 0.77; 95% CI: - 1.3, - 0.28) while a greater number of sutures was associated with higher ultimate failure load ( β= 3; 95% CI: 21, 125). In human cadaveric models, the number of sutures used in triceps tendon repairs may be more important than the fixation type or number of implants for overall strength. If using a transosseous direct repair approach to repair triceps tendon tears, surgeons may choose to use more sutures in their repair in order to balance the risk of larger gap formation when compared to indirect repair techniques.

摘要：
目的：尚不清楚哪一种肱三头肌腱修复构造和技术产生最强的生物力学性能，同时将间隙形成和修复失败的风险降至最低。我们旨在确定构造和技术变量与肱三头肌腱修复的生物力学强度的关联。PubMed,Embase,科克伦图书馆,WebofScience,Scopus,和ClinicalTrials.gov进行了系统的搜索，以获得有关人体尸体三头肌腱修复的生物力学强度的同行评审研究。6篇文章符合搜索条件。在汇集的数据集(123个样本)上进行元回归。感兴趣的结果包括差距的形成，故障模式,和最终失效载荷。协变量是固定类型；植入物的数量；和缝合线的数量。通过协变量进行分层。我们发现固定类型和极限破坏载荷之间没有关联；然而，与经骨直接修复相比,缝合锚钉固定与较少的间隙形成相关(β=-1.1;95%置信区间[CI]:-2.2,-0.04).较大数量的植入物与较小的间隙形成相关(β=-0.77;95%CI:-1.3,-0.28),而较大数量的缝线与较高的极限失效载荷相关(β=3;95%CI:21,125)。在人类尸体模型中，肱三头肌腱修复中使用的缝线数量可能比固定类型或植入物数量对整体强度更重要。如果使用经骨直接修复方法修复肱三头肌腱撕裂，与间接修复技术相比，外科医生可能会选择在修复中使用更多的缝线，以平衡较大间隙形成的风险。
