BackgroundKnee osteoarthritis (KOA) is the most common of osteoarticular diseases. Its increasing incidence with age means that the geriatric population is particularly exposed.ObjectivesThe aim was to study the functional impact of knee OA in elderly subjects.MethodsA cross-sectional study of 52 patients aged ≥65 years, followed for knee OA. Clinical characteristics of knee OA, pain intensity (VAS) were collected. Functional impact was assessed by the short form of the Knee Injury and Osteoarthritis Outcome Score (KOOS-PS) with a score ranging from 0 (no difficulty) to 100 (extreme difficulty). Radiographic severity was classified according to the Kellgren Lawrence criteria.ResultsThe mean age was 73.7±7.8 years and the sex ratio (male/female) was 0.13. KOA was femoro-tibial in 79% and femoro-patellar in 21%, the internal compartment was affected in 98% of cases, and a bilateral involvement was found in 94% of cases. The knees were in varus in 30% of cases, in valgus in 23%. The VAS pain was 6.63±1.89. The mean KOOS-PS score was 48.04±19.1. The radiographic severity stages of KOA according to KL were classified as follows: stage 2 (17%), stage 3 (50%), and stage 4 (33%). A positive and significant correlation between the KOOS and VAS pain was found (r: 0.6; p<0.00). There was no correlation between the KOOS and the radiographic stage (p=0.17), the duration of evolution (p=0.43).ConclusionIn elderly patients with knee OA, there is no concordance between radiographic severity and functional impact. The latter goes hand in hand with the pain experienced.REFERENCES:NIL.Acknowledgements:NIL.Disclosure of InterestsNone Declared.
