“…Kivimaki et a1 (4) found no difference in the frequency of severe knee osteoarthritis among 25-to-49-year-old floorlayers compared with painters, a finding in accordance with our results. Studies from the 1950s showed an increased prevalence of radiological knee osteoarthritis in miners when they were compared with different reference groups without kneeling or squatting work (1,7).…”

ObjectivesThe aim of the present study was to examine the relationship between knee-straining work and radiological findings of knee osteoarthritis and to study the relation between radiological findings and self-reported knee complaints and clinical signs of knee osteoiuthitis. Methods The material consisted of 133 floorlayers, 506 carpenters, and 327 compositors, 26-72 years of age, who had completed a questionnaire and reported no previous knee trauma. A stratified sample of these questionnaire respondents, 50 floorlayers, 51 carpenters, and 49 compositors, were radiologically examined for knee osteoarthritis by 2 radiologists. The X-ray films were independently assessed by 2 radiologists and blinded with respect to knee complaints, trade, and age. R~s u~~s The radiological investigation showed estimated prevalences of knee-osteoarthritis (grades 2 4 ) for 14% of the floorlayers, 8% of the carpenters, and 6% of the compositors (not significantly different). For the subjects 250 years of age the estimated prevalences of the combination of radiological grades 2 4 for knee osteoarthritis and knee complaints during the last 12 months were 29% [95% confidence interval (95% CI) 17-44%], 9% (95% CI 1-26%), and 1% (95% CI 1-10%) for the floorlayers, carpenters, and compositors, respectively. Radiological grades 2 4 were mainly found for subjects above the age of 50 years, subjects with knee complaints, and floorlayers. Radiological knee osteoiuthritis was positively associated with self-reported knee complaints and with clinical signs of intraarticular and retropatellar crepitation. C O~C~U S~O~S The data suggest that work in which a considerable amount of time is spent in knee-straining positions may be a risk factor for the development of knee osteoarthritis above the age of 50 years.

Purpose: To perform a systematic review with best evidence synthesis examining the literature on the relationship between occupational loading tasks and knee osteoarthritis (OA). Methods: Two databases were searched to identify articles published between 1946 and April, 2011. Eligible studies were those that (1) included adults reporting on their employment history; (2) measured individuals' exposure to work-related activities with heavy loading in the knee joint; and (3) identified presence of knee OA (determined by X-ray), cartilage defects associated with knee OA (identified by magnetic resonance imaging), or joint replacement surgery. Results: A total of 32 articles from 31 studies met the inclusion criteria. We found moderate evidence that combined heavy lifting and kneeling is a risk factor for knee OA, with odds ratios (OR) varying from 1.8 to 7.9, and limited evidence for heavy lifting (OR ¼ 1.4-7.3), kneeling (OR ¼ 1.5-6.9), stair climbing (OR ¼ 1.6-5.1), and occupational groups (OR ¼ 1.4-4.7) as risk factors. When examined by sex, moderate level evidence of knee OA was found in men; however, the evidence in women was limited. Conclusions: Further high-quality prospective studies are warranted to provide further evidence on the role of occupational loading tasks in knee OA, particularly in women.

“…Vingård et al [9] found greater risk among male construction workers than other occupational groups. Carpet and floor layers had increased risk of patellar osteophytes, but not tibiofemoral joint degeneration, compared with a reference group of house painters [10]. In a separate investigation conducted by Kirkeskov Jensen et al [11], both carpenters and floor layers, especially those over 50 years of age, had higher prevalence of radiologic OA compared with compositors (seated layout work on video display units).…”

Construction workers, especially carpenters, have a significant number of complaints about knee disorders. Thus, it is desired to identify incident cases of knee disorders and to examine the distribution of specific knee disorders. Clinically sensible algorithms were developed to investigate the medical claims data from the union health plan for carpenters in St. Louis. As a result, 4,900 incident cases of knee disorders were identified among 23,245 medical claims during 1998-2008 and the incidence rate was approximately 153 per 10,000 FTEs (Full-time equivalents). The distribution of knee disorders was 33.1% for acute, 37.1% for subacute, and 29.8% for chronic of the total cases. The majority of carpenters among the total incident cases were Outside Journeymen, who had a much higher percentage of osteoarthritis (32.6% of their total cases). However, it was also noteworthy that Floor Layer Journeymen were diagnosed with more bursitis (32.1%) and Outside Apprentices had a higher percentage of ACL (Anterior cruciate ligament) or PCL (Posterior cruciate ligament) sprain (13.6%) and fracture (10.9%). These results describe the characteristics of knee disorders among union carpenters and provide fundamental health outcome information for further study of knee disorders and occupational risk factors.
