*C-M score=Constant-Murley score 0–100 (100=maximum shoulder function).
†DASH score=Disabilities of the Arm Shoulder and Hand score 0–100 in which 0 is the best shoulder function.
‡EQ-5D index 1−(−0.59) in which −0.59 is the lowest health-related quality of life.
§EQ-VAS (0–100) in which 0 is the lowest health status.
¶Pain VAS (Visual Analogue Scale) 0–100 mm in which 100 is the worst imaginable pain.
**One patient lost between baseline and 3-month follow-up.
