角叉菜胶是一种独特的材料，部分原因是它具有双相特性。软骨的结构是胶原纤维的多孔基质，渗透有滑液，其在关节中产生滑动和接近无摩擦的运动。然而，在体外测试或手术过程中，软骨可能会变干或干燥。这种干燥的效果会影响实验结果。干燥也可能改变体内关节性能。在暴露于露天的马软骨外植体的体外测试中，软骨的平均粗糙度在5小时内从1.85 ± 0.78 μm SD变化到3.66 ± 1.41 μm SD。在暴露于露天的10分钟内观察到单个样品的粗糙度的显著变化。然而，软骨的多尺度性质，其特征在于分形维数，并没有显着改变在同一时期。目前的研究试图量化当软骨从其原生环境中取出时引入的误差大小。
Cartilage is a unique material in part because of it biphasic properties. The structure of cartilage is a porous matrix of collagen fibers, permeated with synovial fluid which creates a gliding and near frictionless motion in articulating joints. However, during in vitro testing or surgery, there exists potential for cartilage to dehydrate, or dry out. The effects of this drying can influence experimental results. It is likely that drying also changes joint performance in vivo. In in vitro testing of equine cartilage explants exposed to open air, the average roughness of cartilage changes from 1.85 ± 0.78 to 3.66 ± 1.41 µm SD in a 5-h period. Significant changes in roughness in individual samples are seen within 10 min of exposure to open air. However, the multi-scale nature of cartilage, characterized by the fractal dimension, does not significantly change during the same period. The current study attempts to quantify the magnitude of error that is introduced when cartilage is removed from its native environment.
