Arthroscopic remplissage is safe and effective: clinical and magnetic resonance results at a minimum 3 years of follow-up

Table 4 Comparison of ROM and the isometric strength of the infraspinatus between the affected shoulder and the contralateral healthy side

Groups	Affected shoulder	Healthy contralateral shoulder	p-value
No. patients (no. of shoulders)	12 (12)	12 (12)
ROM ER1, degrees	75.00 [70.00–75.00]	85.00 [80.75–85.00]	0.0005
ROM ER2, degrees	80.00 [ 80.00–80.00]	90.00 [85.75–90.00]	0.0010
Strength ER1, lbs	12.08 (± 3.13)	12.84 (± 3.11)	0.2375 (n.s.)
Strength ER2, lbs	9.43 [8.44–14.91]	12.70 (± 4.05)	0.0342

Data are expressed as mean (± SD) or median [Q1–Q3]. ER1 external rotation with the arm at the side, ER2 external rotation with the arm at 90° of abduction, lbs pounds; n.s. not significant, Q1 first quartile, Q3 third quartile, ROM range of motion, SD standard deviation
