Table 3.

Prevalence rates broken down by subcategories (individuals, knees) and sex

	Knees	Individuals	Percentage bilateral	Percentage unilateral
Male	41.18% (42/102)	47.06% (24/51)	75.00% (18/24)	25.00% (6/24)
Female	47.27% (52/110)	58.18% (32/55)	62.50% (20/32)	37.50% (12/32)
Total	44.34% (94/212)	52.83% (56/106)	67.86% (38/56)	32.14% (18/56)

There were no sex‐based differences. Of the 56 individual cases, bilateral cases were significantly more prevalent than unilateral ones. Bilateral cases were more prevalent than unilateral in males (n = 24), but there was no difference in females (n = 32). Within unilateral cases, fabellae were equally likely to be present in the right or left knee. There were no differences between the sexes (see text for test statistics and P‐values).
