MMP-3 is chronically upregulated and correlates with decreased GAG content in the synovial fluid of the operated knee in patients 40 years after meniscectomy. a MMP-3 and b GAG protein levels within the synovial fluid of patients 40 years post total meniscectomy in operated or non-operated knees (n = 8). c Correlation of absolute GAG levels plotted against absolute MMP-3 levels in the synovial fluid all knees (n = 16)
