Objective:
To evaluate the quality of life in patients with knee and hip osteoarthritis through self-assessment and those made by the physician.
Materials And Methods:
An observational and cross-sectional multicenter study in which 628 traumatologists or rheumatologists evaluated 1,849 patients with knee and/or hip osteoarthritis, aged ≥ 50 years old, and representative of 49 Spanish provinces. Each researcher evaluated three patients and also completed the SF-12v2 health questionnaire. The patients completed the WOMAC and SF-12v2 questionnaires.
Results:
The patients were 68.5 ± 9.5 years old, 61.5% had knee osteoarthritis, 19% had hip osteoarthritis, and 19.5% in both locations. Older patients and those who had both knee and hip osteoarthritis had a poorer quality of life, according to patients and researchers. Physical health perceived by the researchers was better than patients reported (36.74 ± 8.6 and 35.21 ± 8.53; respectively, p<0.001), and the mental health score was similar between physicians and patients. Kellgren/Lawrence scale and test Timed Up & Go predict better the quality of life, assessed by WOMAC and SF-12v2 questionnaires.
Discussion:
This is the Spanish study on quality of life in osteoarthritis of the knee and hip of larger amplitude and number of patients.
Conclusion:
These results could be considered as reference values of Spanish population aged ≥ 50 years with knee or hip osteoarthritis.
