[Correlation of roentgen findings, intensity of pain and subjectively experienced impairment in gonarthrosis].

At the Orthopedic Clinic of the Heinrich Heine University of Düsseldorf a clinical survey was carried out about patients with clinically obvious gonarthrosis. Wirth's rating was used to classify the x-ray state. The survey revealed the following correlations: Between the x-ray state according to Wirth and pain intensity measured by VAS scales exists a significant positive correlation (p < 0.001). Between the x-ray state according to Wirth and the individual clinical impairment measured by a modified LYSHOLM-SCORE exists a significant positive correlation (p < 0.001). The survey shows that the LYSHOLM-SCORE modified by Kloos does reveal the subjective impairment caused by gonarthrosis. The survey points out that on the one hand the subjective impairment at Wirth's x-ray state IV is higher than at state III, but that on the other hand the pain-score is higher at state III than at state IV.
