Figure 5:
Radiographic knee osteoarthritis grade 2-4; prevalence estimates
and 95% CI by knee complaints, and age groups
Knee demanding work
and self-reported knee complaints
A dose-response-relationship for knee
complaints more than 30 days during the
last 12 months was found with an OR 3 for
low-moderate knee demands (1-8): OR 4
for high; and an OR 7 for very high knee
demands, as shown in fi gure 6.

Knee demanding work
and radiological knee OA
≥ 50 years
A dose-response-relationship for radiological
knee OA, grade 2-4 was found with
an OR 3 for low-moderate exposure,
OR 4 for high and an OR 5 for very high
exposure. Only for very high exposure
the result was signifi cantly increased
(wide confi dence intervals), as shown
in Figure 7.
