Comparison of Complication rates between polyethylene insert spacers and all-polyethylene tibia spacers. P-values are calculated using Fisher’s exact test.

Antibiotic-related	13 (10)	4 (6)	9 (14)	0.24
Spacer-related	13 (10)	6 (10)	7 (11)	1
Recurrent infection	19 (15)	9 (15)	10 (16)	1
Medical complications	31 (25)	13 (21)	18 (28)	0.41
