This study developed and validated the Activities of Daily Living Scale (ADLS) of the Knee Outcome Survey. It is a 17-item patient-reported outcome measuring how knee symptoms and function affect daily activities. Unlike older scales built for a single diagnosis, the ADLS was designed to work across many knee disorders.
When you pick a patient-reported outcome for a knee patient, match the tool to the population and the construct you want to measure. The ADLS was built to span ligamentous, meniscal, patellofemoral, and arthritic conditions, so it is useful when a patient has more than one problem, where single-diagnosis scales fall short.
Understand why internal consistency matters clinically. The ADLS alpha of 0.92 to 0.93 gives a 95% confidence interval of roughly plus or minus 12 points, versus nearly plus or minus 25 points for the Lysholm Scale. A more precise score means a change is more likely to be real.
Know the ceiling effect: the ADLS measures low-level daily activities, so an athlete may max out the scale despite real deficits. Use the companion Sports Activity Scale for high-demand patients. For boards, remember the Nagi framework (active pathology, impairment, functional limitation, disability) and that the ADLS targets functional limitation.
