Figure 2
Histopathologic assessment of fibrosis in the periarticular knee tissue. Histopathologic fibrotic scores of H&E-stained sections for the periarticular tissue and representative images from the three patient groups (PTKA = primary TKA, RTKA-A = arthrofibrosis, RTKA-NA = non-arthrofibrosis). The graphs depict mean fibrous tissue score ± standard deviation, with each data point representing one patient. Asterisk denotes a significant difference, (**p ≤ 0.01), by the Wilcoxon Rank Sum test. All images were taken using the 10X objective on a Nikon E600 bright-field light microscope.
