Table V.

Normalized quantitative atrophy. Inline graphic

Muscle atrophy was comparable for all rotator cuff muscles between CTA, MRCT, and OA patients, except for the supraspinatus which was significantly more atrophied in CTA and MRCT than in OA.

Variable Healthy, % CTA, % IRCT, % OA, %
Supraspinatus 0 53 52 37*
Subscapularis 0 33 37 38
Infraspinatus 0 39 38 29
Teres minor 0 21 22 29

Values significantly different (p = 0.002).
