Description
Sibel Bozgeyik-Bagdatli and colleagues published a 2026 cross-sectional study of symptom burden across the severity grades of knee osteoarthritis. Eighty-two patients were sorted into grades two, three, and four on the Kellgren-Lawrence X-ray scale. They were then compared on pain, sleep, daily function, walking and standing tests, and leg strength. Age and body mass were accounted for.
The most advanced grade carried the heaviest burden. Grade four patients reported worse constant pain than grade two patients. They moved more slowly on the timed up-and-go test. Their thigh muscle was weaker in the sore knee, and they rated knee function lower. Differences between grades two and three, and between three and four, were much narrower. Sleep scores did not differ significantly. The authors say the top grade marks a clear step up in suffering.
