Electromechanical properties of osteochondral samples, as analyzed by Arthro-BST. Electromechanical properties of samples stored in different temperature and nutritive medium conditions were evaluated after 14 and 28 days. Freshly harvested cartilage was used as control. Quantitative parameter (QP) measurements are presented as arbitrary units (mean ± standard deviation). *p < 0.001 (fresh versus −70 °C and 37 °C group after 14 days, and versus all other groups after 28 days); **p < 0.001; ^# p < 0.05
