Knee osteoarthritis, knee pain, quality of life, older adultsAbstract
The objective was to determine the impact of knee osteoarthritis (OA) on the quality of life (QoL) in older adults. A sample of 154 patients diagnosed with knee OA was included. The Kellgren–Lawrence scale was used for the radiological diagnosis of knee OA, and the WOMAC index was applied to assess QoL in patients with this condition. For the bivariate analysis, Somers’ D test was used. For the multivariate analysis, a Poisson regression model with adjusted prevalence ratio (APR) was applied. Statistical significance was set at p<0.05. Among the results, the prevalence of knee OA was mild in 20.1%, moderate in 53.2%,
and severe in 26.6%. QoL was reported as good in 38.3%, fair in 51.3%, and poor in 10.4% of the patients. Only severe knee OA significantly impacted QoL (p = 0.021), showing a 48% lower probability of having good QoL compared to those with mild knee OA (APR = 0.52, 95% CI: 0.29–0.91). Women had a 45% lower probability of presenting good QoL compared to men (APR = 0.55, 95% CI: 0.37–0.80). In conclusion, severe knee OA significantly impacted the QoL of older adult patients, with women showing a lower probability of having good QoL.
