Data are n (%), mean (SD), or median (IQR). Oxford Shoulder Score range 0 to 48. Modified Constant-Murley Score range 0 to 100. PainDETECT score −1 to 38. Hospital Anxiety and Depression Scale (HADS) Depression and Anxiety Score range 0 to 21. EuroQol 5 dimensions 3 level index (EQ-5D-3L) range −0·59 to 1·0. EuroQol visual analogue scale (EQ VAS) range 0–100. A higher score indicates a better state for all measures except for HADS and PainDETECT.
