ABSTRACT
A primary concern of many knee surgery patients is their ability to return to work
following surgery, but it is often difficult to predict the practicality of returning
due to a job's unclear knee demands. A cross-sectional study of employed patients
and general population participants was conducted. Study participants were asked if
their job required nine separate tasks and if their job had low, moderate, or high
physical demands. The relative risk of each task placing high demands on the knee
was calculated, and those risk ratios were summated to calculate a scaled score. The
scaled score accurately distinguishes the levels of job demands with each reported
level of job demands having a significantly higher mean scaled score than the level
below it (p < 0.0001). The Occupational Activities Knee Scale offers occupational and health
care providers greater precision in comparing the physical requirements of jobs for
knee surgery patients.
