Figure 3
Picrosirius red staining of periarticular knee tissue. Picrosirius red staining quantification and representative images of three patients from the three patient groups (PTKA = primary TKA, RTKA-A = arthrofibrosis, RTKA-NA = non-arthrofibrosis). The graphs depict mean picrosirius red staining (PSR) percent area ± standard deviation, with each data point representing one patient (average of three areas). Asterisk denotes a significant difference, (*p ≤ 0.05; ****p ≤ 0.0001), by the Wilcoxon Rank Sum test. The scale bar applies to all images in this figure.
