Domain	Pre-operative ± SD	3 months ± SD	6 months ± SD	12 months ± SD	Effect size¥
Overall	45 ± 11	68 ± 15	70 ± 16	72 ± 15	2.3
Function	54 ± 16	75 ± 11	77 ± 12	67 ± 16	0.9
ADL§	57 ± 20	72 ± 25	78 ± 18	81 ± 17	1.5
Work	56 ± 21	65 ± 30	72 ± 23	77 ± 19	1.3
Pain	66 ± 13	33 ± 23	39 ± 21	22 ± 19	3.5

Satisfaction	32 ± 12	65 ± 19	70 ± 21	61 ± 31	2.3

^#The MHQ domains are based on a scale of 0 to 100. For all domains except pain a higher score indicates better performance. For the pain domain a lower score indicates less pain

^¥The effect size is defined as (mean₂ − mean₁)/(Standardized Response Mean). For example for the Overall MHQ score effect size = (72 − 45)/(11.9) = 2.3. Effect size of 0.2 is small, 0.5 is medium and 0.8 is large.
