From: Differences in levels of inflammatory mediators in meniscal and synovial tissue of patients with meniscal lesions

   Meniscus (pg/mg) Synovium (pg/mg)
   IM NIM p - value NS FS p - value

  1. TNF-α tumor necrosis factor-alpha, IL-6 interleukin-6, NGF nerve growth factor, IM injured meniscal site, NIM non-injured meniscal site, NS synovium ‘nearest’ the lesion, FS ‘farthest’ synovium, n.s. not significantly different, SD standard deviation
