- Data are absolute values and percentages of positively stained cells in women’s samples for the 4 parameters of the Bonar Scale: it allows a semiquantitative analysis of tendinopathy considering alterations of tenocytes, ground substance, collagen and vascularity. Each parameter is scored with a four-point scoring system, with 0 indicating healthy tissue and III highly degenerated tissue. The final score is comprised between 0 (normal tendon) and 12 (most severe abnormality detectable)
