PSRCT	46.7% (529)	31.4% (199)
Full-thickness	17.4% (197)	11.2% (71)
Partial-thickness	29.3% (332)	20.2% (128)

^*A total of 1,132 subjects had complete MRI studies, and 634 met all inclusion criteria. The values are given as the percentage, with the number of subjects in parentheses.

^†Subjects with symptomatic PSRCT were identified using the criteria of Moosmayer et al.²⁴.

^‡The bilateral percentage came from data compiled before we excluded 1 shoulder for each of the 634 subjects.
