In the knee rating scenario where a brace is prescribed but there is no objective disability, what is the standard rating?

• A. 10%
• B. 15%
• C. 25%
• D. 40%

Answer: (D)

When a knee condition requires a brace but there’s no objective disability documented, the rating uses the presence of a brace as a strong indicator of substantial ongoing impairment. The brace shows the knee can’t function at a normal level in daily activities or work, even if exam measurements don’t reveal a clear deficit. That level of functional limitation is captured by a relatively high rating, and 40% reflects a significant, enduring impact on typical knee-related tasks and work capacity without needing objective ROM or stability findings to justify it.

Lower percentages would apply if the impairment were milder or well-supported by objective findings; the brace-alone scenario signals more substantial functional limitation, so 40% is the standard rating chosen.
