- Data represent the means (standard error) for each group. As the severity of cartilage lesions increases, so does the score obtained using the Mankin grading method. The Normal group includes normal articular cartilage group that did not undergo any surgery or treatment. The nutritive mixture solution (NMS) group received NMS after surgery. The normal saline (NS) group received NS after surgery. *Differences among the three groups were considered to be statistically significant when the P value was under 0.05 by one-way analysis of variance and Tukey HSD test, or Kruskal-Wallis test, depending on normality of data. a,b,cData with different letters in the three groups are statistically significantly different.
