	Preoperative	Immediately	1 week	1 month	2 months	3 months	6 months	12 months	24 months
CLDH	9 (5–10)	2 (1–4)	2 (1–8)	2 (0–5)	1 (0–4)	1 (0–3)	1 (0–3)	1 (0–3)	0 (0–3)
ULDH	8 (6–10)	2 (0–4)	2 (0–9)	2 (0–6)	1 (0–4)	1 (0–3)	1 (0–3)	1 (0–2)	0 (0–3)
p-valuea	0.211	0.049	0.152	0.893	0.641	0.693	0.994	0.520	0.774

^a Values are expressed in the format of “Median (Min-Max)”. Mann-Whitney U test was used to compare the VAS score between CLDH and ULDH groups at every point of time
