Hematoxylin and eosin stains demonstrating the disorganization score used for analysis of the PAOM.

(A) Disorganization score of zero, with parallel collagen bands with no interspersed adipose tissue. (B) Disorganization score of one, demonstrating collagen bands with altered orientation focally with no interspersed adipose tissue. (C) Disorganization score of two, with collagen bands with altered orientation diffusely with small amount of interspersed adipose tissue. (D) Disorganization score of three, with poorly arranged collagen bands with significant amount of interspersed adipose tissue.</p
