California Workers Compensation Claims Practice Test 2026 – Self Insurance Exam Prep

In California workers' compensation, the mechanism for rating disabilities is based on the Permanent Disability Rating Schedule (PDRS). For a knee injury that results in no objective disability yet requires the use of a stretch knee brace, this indicates that there is some level of impairment, albeit not one that is physically observable.

The use of an assistive device, such as a knee brace, often signifies a certain degree of functional limitation, which can warrant a disability percentage rating. For injuries with no objective findings but that require a supportive device, a common benchmark is a percentage around 10%. This figure reflects the acknowledgment of the need for ongoing support or accommodation without a direct and objective physical disability being present.

Higher percentages, such as 20%, 30%, or 40%, would typically correspond to more significant objective disabilities or functional impairments, which do not apply in this scenario since the injury is characterized by a lack of observable disability despite the need for a brace. Consequently, a 10% rating aligns properly with the guidelines for non-objective conditions requiring adaptive aids.
