The study is retrospective in nature, and is not based on clinical trial or experimental data. Additionally, DEA results are inherently sensitive to sampling: adding or subtracting individuals from the sample may change the baseline against which efficiency and rehabilitation potential are measured. As such, therapists using this approach must ensure that the sample is representative of the general population, and must not contain significant measurement error.
Third, individuals who choose total knee arthroplasty will incur a transient disability. However, this population does not generally fit the World Health Organization International Classification of Functioning, Disability and Health definition of disability if the surgical procedure is successful.
Since the study focuses on the outcomes of physical therapy, range of motion measurements and circumferential measurements were chosen as opposed to the more global measures of functional independence such as mobility, transfers and stair climbing. Applying this technique to data on patients with different disabilities (or the same disability with other outcome variables, such as Functional Independence Measure scores) may give dissimilar results.
