Which scenario yields a 40 percent knee rating?

• A. Stretch knee brace with no objective disability.
• B. Long leg brace with no objective disability or work restrictions.
• C. No objective disability but brace prescribed.
• D. Knee injury with precluded heavy lifting.

Answer: (B)

In this knee rating scenario, the important idea is how the level of impairment is reflected by the use of an assistive device. A long leg brace signifies a substantial functional impact on the knee—enough to warrant a fairly high rating—even when there aren’t documented objective measurements or work restrictions. The brace itself communicates that the knee’s function is significantly limited in daily activities, which aligns with a 40 percent knee rating under the applicable impairment guidelines.

A stretch knee brace is lighter and typically indicates less impairment, so it wouldn’t usually reach that 40 percent level. No objective disability but a brace prescribed suggests some impairment, but the lack of objective findings generally points to a lower rating. And a knee injury with precluded heavy lifting involves work restrictions, but the rating would depend on how impairment and restrictions combine under the guidelines, not automatically equating to 40 percent from the restriction alone.

So, the long leg brace with no objective disability or work restrictions best corresponds to the 40 percent knee rating because its severity is conveyed by the need for substantial external support.
