The primary purpose of using a handheld dynamometer in knee assessments is to quantify muscle strength. This device is designed to measure the amount of force produced by specific muscle groups around the knee joint during contraction. Accurate measurement of muscle strength is critical in rehabilitation settings or when evaluating athletic performance, as it helps clinicians understand the functional capabilities of the muscles that support the knee. This information can guide treatment plans, monitor progress, and determine the effectiveness of interventions aimed at improving muscle strength.

While other assessments, like measuring range of motion, assessing pain levels, or evaluating joint stability, are important in a comprehensive knee evaluation, they are not the primary function of a handheld dynamometer, which specifically focuses on muscle strength.
