  1. The table lists the top 10 gene ontology (GO) categories for the 4,175 genes that were differentially expressed between orthopedic biopsies and for the 1,536 differentially expressed genes that were found to vary between arthroscopic biopsies. Seven of the top 10 GO categories were common between the two biopsy types. In the columns headed 'Rank', category 1 is the most significant category and the category with the highest number is the least significant. EASE, Expression Analysis Systematic Explorer.
