Type 3 finger length pattern is associated with total knee replacements due to osteoarthritis but not with hip replacements or hand osteoarthritis in the elderly: The AGES-Reykjavik study

Table 1 Results for the photography population

Photography population (n=5170)
		Knee OA		Hip OA		Hand OA
		TKR(n=223)	No TKR (n=4947)	THR(n=316)	No THR(n=4854)	Severe(n=673) not severe(n=4497)
Age, mean(SD) years		76.9(5.4)	76.4(5.5)	77.9(5.9)	76.4(5.5)	77.5(4.3)	75.4(4.8)
Percent female		64	57	57	65	73	55
BMI, mean (SD)		29.5(4.7)	26.9(4.4)	27.8(4.5)	27.0(4.4)	26.0(4.2)	27.6(4.3)
Finger pattern (visual photographic,%)

	2	30	38	36	38	33	38
	3	61	49	53	49	53	49

The prevalence of type 3 finger length pattern was higher in the population with TKR compared to the population without knee replacement. No such relationship was seen for THR or hand osteoarthritis.
