Abstract
Increasing emphasis is placed on outcomes research. In this community study knee outcomes scores were evaluated in a ‘normal’ elderly population
The American knee society (AKS), Oxford, and Bristol knee scores were recorded in 100 elderly people without a history of lower limb disorder. The mean age of subjects was 72 years. Mean normalised scores were 90%, 91% and 94% for AKS, Oxford and Bristol knee scores respectively. There were significant negative correlations between knee score and advanced age (p< 0.001) and knee score and co-existent major medical disorders (p< 0.001). The function component was the score component most senitive to these variables (p< 0.001)
Control studies are necessary if knee scores are to be taken as accurate measures of outcome. Comparison of outcome after knee replacement on the basis of knee scores should take account of demographic variables. Scores with a large ‘function’ component appear to be more susceptible to demographic variation.
