Table 3. Clinical Characteristics of Intact and Retear Groups.

Characteristic	Intact Group (n = 30)	Retear Group (n = 20)	P
Age, years	63.4	64.2	0.107
Tear size, cm	1.4	2.3	0.001
Retraction size, cm	1.4	2.6	0.002
Fatty grade of SST*	1.9	2.5	0.094
Fatty grade of IST*	1.1	1.5	0.183
Fixation technique, S/D, n	10/20	7/13	0.818

All data are presented as means unless otherwise noted. ^*Fatty grade was evaluated using criteria established by Goutallier et al.(22) on the basis of fatty streaks within the muscle belly.

D = double rows, IST = infraspinatus tendon, S = single row, SST = supraspinatus tendon
