Inflammation or damage to the femoral nerve, which may cause pain, numbness, or weakness in the thigh and knee.
Medical records and examination findings that document how much strength and function you have lost in your quadriceps are central to this rating. A VA or private examination that directly tests the power of the quadriceps extensor muscles helps show whether paralysis is complete or, if incomplete, how severe it is. Nerve conduction studies or electromyography can provide objective evidence of the degree of nerve damage. Records showing you have difficulty straightening your knee, climbing stairs, or bearing weight support a higher level of incomplete paralysis. If your nerve damage causes only sensory symptoms such as numbness or pain rather than weakness, the regulation limits the rating to mild or moderate. Statements from you or people who know you, describing how weakness or sensory loss affects your ability to walk, work, or perform daily activities, can help show the functional impact at each level.
