Table V.
Normalized quantitative atrophy.
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).
CTA, cuff tear arthropathy; IRCT, irreparable rotator cuff tear; OA, osteoarthritis.
