We evaluated the relationship between clinical symptoms and the radiographycal findings in patients with osteoarthritis of the knee.
There were significant correlations between the score of pain on walking and either the radiographical width of the medial femoro-tibial joint space or the femorotibial angle. This score was significantly reduced in patients who showed marked differences in femorotibial angle between the standing and supine position. These findings suggested that the joint instability is one of the factors of knee pain. There was no relationship between the incidence of osteophyte formation and the score of pain on walking.
