This study was aimed at evaluating the biomechanical properties and gapping characteristics of tendon repair methods using a combination of a three-loop pulley (3LP) pattern, a titanium plate, and a polycaprolactone (PCL) plate in a rabbit gastrocnemius tendon (GT) model ( = 50). GTs were randomly assigned to five groups ( = 10/group). Transected GTs were repaired with a 3LP pattern alone or in conjunction with an epitendinous suture (ES), a 5-hole 1 mm PCL plate, a 5-hole 2 mm PCL plate, or a 5-hole 1.5 mm titanium plate. The yield, peak, and failure force, as well as the occurrence and force of 1-mm and 3-mm gapping were examined. The mean yield, peak, and failure force of the 3LP + titanium plate group were higher than that of other groups. The biomechanical properties of a 3LP + a 2 mm PCL plate were similar to 3LP + ES constructs in this model. In all specimens in all groups, 1 mm gap formation was observed. The frequency of 3 mm gap formation was 70% and 90% in the 3LP + 2 mm PCL plate group and the 3LP + 1.5 mm titanium plate group, respectively. Additional studies evaluating PCL plates to determine the effect on the healing and blood supply of tendon are needed.
本研究旨在使用三环滑轮（3LP）模式、钛板和聚己内酯（PCL）板的组合，在兔腓肠肌腱（GT）模型（n = 50）中评估肌腱修复方法的生物力学特性和间隙特征。GT被随机分为五组（每组n = 10）。横断的GT分别采用单独的3LP模式或与腱周缝合（ES）、5孔1 mm PCL板、5孔2 mm PCL板或5孔1.5 mm钛板联合修复。检测屈服力、峰值力和破坏力，以及1 mm和3 mm间隙的出现情况和间隙力。3LP +钛板组的平均屈服力、峰值力和破坏力高于其他组。在该模型中，3LP + 2 mm PCL板的生物力学特性与3LP + ES结构相似。在所有组的所有标本中，均观察到1 mm间隙形成。3LP + 2 mm PCL板组和3LP + 1.5 mm钛板组中3 mm间隙形成的频率分别为70%和90%。需要进一步评估PCL板以确定其对肌腱愈合和血供的影响的研究。
