“…However, both studies had lower numbers of participants (Յ48) and there was concern that findings in control knees may be confounded by the contralateral case knees due to the between-knee, withinperson study design and lack of independence of observations in bilateral knees of the same person. For instance, strength in an asymptomatic knee may be reduced by contralateral pain status through a mechanism of central inhibition (40), or through reduced physical activity/function in general (41). However, our current data are in principal agreement with these findings and confirm, in a very large cohort, that pain is a more relevant factor in determining muscle strength than the radiographic disease stage in KOA in both men and women.…”

Objective. To determine whether thigh muscle strength differs between symptomatic and asymptomatic knees, and/or different radiographic strata of knee osteoarthritis (KOA). Results. Isometric strength was significantly lower in symptomatic than in asymptomatic legs: ؊11 to ؊13% for extensor strength and ؊7 to ؊16% for flexor strength (P < 0.0001 for both) in men, and ؊9 to ؊17% (P ‫؍‬ 0.029) for extensor strength, and ؊10 to ؊21% (P ‫؍‬ 0.049) for flexor strength in women. Similar observations were made for pain frequency strata. Extensor and flexor strength were not significantly different across K/L grade strata in asymptomatic legs in either sex (P > 0.12). However, strength normalized to body weight was lower at higher K/L grades in both sexes (P < 0.02) because the body mass index was greater in participants with more advanced radiographic disease. Conclusion. Knee symptoms (i.e., pain) appear to be the relevant determinant of isometric knee extensor and flexor strength in KOA, whereas no direct association between strength and radiographic severity was observed. These findings suggest that the reduction in thigh muscle strength in KOA is related to pain but not to the structural (radiographic) disease status.

Objective: To investigate the significance of the severity of knee osteoarthritis in physical function measures and isokinetic strength. Material and Methods: Females were included if they were between 50-65 years old, had radiological evidence of grade 2 (n=27) and grade 3 (n=26) osteoarthritis according to the Kellgren-Lawrence criteria, and were volunteers. Patients were excluded if they had knee osteoarthritis secondary to inflammatory arthritis, had significant morbidity that would preclude their undertaking the tests, had participated in any physical activity program in the previous 6 months, and had a knee operation. Knee pain with rest/activity, chair stand test, up-and-go test, stair ascent and descent time, and isokinetic concentric knee flexor and extensor peak torque at 90°/s, 120°/s, 180°/s, and 300°/s speed were assessed. Results: All females had bilateral tibiofemoral and patellofemoral osteoarthritis. There were no differences between the groups according to age, body mass index, pain duration, visual analog scale with movement and rest, or isokinetic strength at different speeds. The performance of the stair descent time and up-and-go tests was better in the grade 2 group than grade 3 group (p<0.05). Conclusion: It is known that the decrement of physical function accelerates with the increment of the severity of knee osteoarthritis. In this study, we found that the severity of knee osteoarthritis affected the stair descent time and up and go test.
