Radiographic knee osteoarthritis and<br />
self-reported knee complaints in fl oor layers and carpenters<br />
Lilli Kirkeskov Jensen, MD PhD<br />
Background<br />
During many years workers from the<br />
construction industry have had knee<br />
disorders, but none of them had their<br />
disorders accepted as an occupational<br />
disorder and many were unable to work<br />
because of their knee troubles. Earlier<br />
studies had shown an increased risk for<br />
knee osteoarthritis (OA) among miners<br />
[1, 2], pipe fi tters [3] and welders [4, 5]<br />
and some occupations seemed to have<br />
a high prevalence of prepatellar bursitis<br />
[6-8].<br />
This study was carried out between 1993<br />
and 1995 on fl oor layers with high knee<br />
demands, carpenters with moderate knee<br />
demands and a control group of graphic<br />
designers without kneeling work activities.<br />
The research questions were:<br />
� Is there a relationship between work<br />
with knee-straining work activities,<br />
self-reported knee complaints, and<br />
radiological fi ndings of knee osteoarthritis?<br />
� Is there a relationship between selfreported<br />
knee complaints, clinical<br />
fi ndings, and radiological knee osteoarthritis?<br />
� Is there a dose-response-relationship<br />
between work with knee demanding<br />
work activities and self-reported knee<br />
complaints and/or radiographic knee<br />
osteoarthritis?<br />
This paper is based on results from papers<br />
from 2000 and 2005 based on the same<br />
study which took place in the period<br />
1993-1995/1996 in the Area of Copenhagen,<br />
Denmark. The whole project<br />
consisted of:<br />
1. A review of earlier literature on occupational<br />
knee disorders [9],<br />
2. Exposure measurements by videorecordings<br />
on the knee demands in<br />
fl oor layers, and carpenters [10, 11],<br />
3. Questionnaire study on self-reported<br />
musculoskeletal disorders in fl oor<br />
layers, carpenters, and compositors<br />
[10],<br />
4. Clinical examination on a selected part<br />
of the questionnaire responders[10],<br />
and<br />
5. Radiological examination on a selection<br />
of the study population[12, 13].<br />
Methods<br />
General description of the three trades<br />
Floor layers and carpet layers install linoleum,<br />
carpet, and vinyl fl oorings. The work<br />
tasks include removal of old fl oorings,<br />
grinding, fi lling, installation of underlay,<br />
measuring and cutting of materials, gluing,<br />
welding and installation of skirting<br />
board (fi gure 1, page 72).<br />
