Despite a small proportion of our patients had a formal job, very few had lost it because of the disease. Only 4% of the patients were unable to do any physical activity and 25% had low WOMAC scores and no physical limitations at all. These findings suggest that the severity of knee OA in our study was actually mild to moderate and that its pattern is certainly similar to that of patients attending primary care units in which OA referrals to specialized departments depends on the need for joint replacement, physical therapy and rehabilitation, comorbidities management, and demographic factors.<a class="elsevierStyleCrossRefs" href="#bib0040"><span class="elsevierStyleSup">8,34–40</span></a> Despite all patients in our study were under the care of GPs, most of them were already seen by rheumatologists and orthopedic surgeons.</p><p id="par0095" class="elsevierStylePara elsevierViewall">The overall and last episode of pain lasted for more than 5 years and around 6 months, respectively and their intensity was 5.2 on a VAS.

The contribution of country origin was significant in all 3 logistic regression models.

Compared with Mexicans, Brazilians were 0.29 and 0.22 times less likely to be on NSAIDs or present disability than Mexicans. Argentinians were 0.23 times less likely to present disability than Mexican patients. The significance of the variable country of origin as predictor of pain level, disability, and NSAIDs usage might support the role of each country health-care systems and less likely ethnicity in the burden of knee OA.</p><p id="par0120" class="elsevierStylePara elsevierViewall">For every additional medical visit, patients were 0.83 times less likely to report pain ≥5.2, but 1.7 times more likely to present disability. Each incremental unit in VAS pain was associated with 1.29 and 1.19 more chances of being on NSAIDs and having disability. Patients who had a drug prescription were 2.8 times more likely to present pain equal or above to 5.2 on a VAS and 2.18 times more likely to present disability. For each year increment on age there is a 0.98 times less chance to receive NSAIDs in this population.</p><p id="par0125" class="elsevierStylePara elsevierViewall">There were some potential limitations to our study. Regarding the representativeness of the populations included in our study, our approach was the identification of knee OA at primary health care clinics. In this regard, we followed the usual steps took by the patients with knee OA in the 3 countries. Following a standard protocol, GPs referred consecutive knee OA patients to the rheumatologist for detailed characterization of demographic and clinical variables. Differences between countries in regard to demographic and access to care seemed to reflect the characteristics of the population and health care in each of the 3 countries.</p><p id="par0130" class="elsevierStylePara elsevierViewall">In conclusion, the burden of knee OA in Latin American countries seems to be related with demographic factors, including the characteristics of the health system. Knee OA in primary health clinics seems to be a mild form of disease with mild impact on functioning. At this stage, knee OA could be the target of disease modifying agents as treatment. We think that the assessment of disease, particularly knee OA should include the individual analysis of each Latin American country. By following that approach, health care planning, from detection of disease to its treatment would be more appropriate to the needs of each country.</p></span><span id="sec0045" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0115">Source of Funding</span><p id="par0135" class="elsevierStylePara elsevierViewall">Supported by an unrestrictive fund from <span class="elsevierStyleGrantSponsor" id="gs0005">Expanscience Laboratories</span>.</p></span><span id="sec0050" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0120">Conflict of Interest</span><p id="par0140" class="elsevierStylePara elsevierViewall">Hafid Halhol is employed by Laboratories Expanscience.
