a

Location: Alsace: Germany at the time, now France.

b

67/529 individuals had fabellae.

c

Estimated 72 fabellae based on an prevalence rate of 17.6%.

d

Estimated 145 fabellae based on an prevalence rate of 14.5%.

e

When translated from characters, the spelling could be Ooi or Oi.

f

Reported location was Aino, taken from Hessen (1946).

g

Reported location was Hokuriku‐Japaner.

h

Estimated 83 fabellae based on an prevalence rate of 28.42%.

i

Hessen had 96. Sutro had 81 patients with at least one fabella. 106 patients had roentgenograms of both knees, 16 were bilateral. Therefore, there are 97 fabellae in total.

j

11/31 individuals had fabellae.

k

Estimated 18 fabellae based on an prevalence rate of 27%.

l

Reports on fabellae in medial head – ignored here, as it is unusually high, particularly given the lack of medial fabellae in other studies.

m

Reports a couple of medial fabellae – not possible to tease them out, prevalence rate may be too high.

n

Prevalence rate of 31.25% (25/80) for individual. Unknown if one or two knees were inspected per individual.
