Maximizing Your VA Rating for a Knee Disability

For veterans with a service-connected knee condition, securing the appropriate disability rating is crucial for accessing the compensation and benefits they’ve earned. However, the Department of Veterans Affairs (VA) rating system for the knee is complex, often leading veterans to receive lower ratings than they deserve. The key to maximizing your overall rating lies in understanding that a single knee injury can result in many separate, distinct ratings—and that the VA has a legal obligation to help you get them.

The Power of Separate Ratings

A common misconception is that a single knee problem only warrants one overall rating. In reality, the VA’s rating schedule (Diagnostic Codes 5257, 5260, 5261, etc.) allows for multiple, concurrent ratings for the same knee, provided each rating covers a different functional impairment or symptom.

These separate ratings are absolutely essential to boosting your overall VA rating, particularly because the VA uses a combined rating table, where higher individual ratings are disproportionately more valuable. For instance, a veteran can receive distinct ratings for multiple impairments related to the same knee.

Key Separate Rating Areas:

1. Limitation of Flexion: This is rated based on the inability to bend the knee fully. The rating severity increases as the maximum angle of flexion decreases. For example, a veteran unable to flex beyond 45 degrees will receive a higher rating than one who can flex to 90 degrees
2. Limitation of Extension: This covers the inability to straighten the knee fully. The lowest compensable rating is often given for an inability to extend the leg completely (stuck at 50 degrees or more of flexion). This is a static disability that significantly affects gait.
3. Instability (Subluxation or Ligament Laxity): This is the feeling that the knee is “giving way” or having excessive side-to-side or front-to-back motion, typically due to torn ligaments (ACL, MCL, PCL, LCL). It is rated based on severity—slight, moderate, or severe—and is a critical component to maximize the overall rating.
4. Painful Motion (Functional Loss): Even if the veteran’s measured range of motion (flexion and extension) falls within the non-compensable limits, a minimum 10% rating can be assigned if the movement of the knee joint is painful. The VA must consider the entire arc of motion, and if pain limits the efficient use of the joint, a rating is warranted.
5. Ankylosis (Fusion of the Joint): In the most severe cases where the knee joint is permanently stiffened or fused, a rating is assigned based on the angle of fixation.

Crucially, because each of these ratings covers a separate symptom and functional loss, a veteran can receive all of them simultaneously. For example, you could receive a rating for limited flexion and a separate rating for knee instability, as they represent different ways the joint is impaired. This multiple-rating approach, where different manifestations of the disability are rated distinctly, is your path to maximizing the overall combined rating. Always ensure your medical records and your Compensation & Pension (C&P) exam clearly document all of these symptoms.

The VA’s Duty to Maximize Benefits

Veterans should also be aware of the VA’s duty to maximize benefits. This is a fundamental principle of veterans law, which holds that the VA is required to help you gather evidence to support your claim (Duty to Assist) and, in situations where evidence is equally balanced for or against a claim, the VA must resolve the doubt in your favor (Benefit of the Doubt Rule).

More than simply assisting with evidence, the duty to maximize benefits means the VA must ensure you receive the highest possible schedular rating supported by the evidence in your file. This includes looking beyond the most obvious condition (like arthritis) and assigning the most favorable diagnostic code (such as rating for both limitation of motion and instability). If the medical examiner only notes your limited flexion but overlooks the instability you report, the VA has a duty to send you back for a clarifying exam or ensure all symptoms are considered under the “functional loss” criteria.

You do not have to be an expert on the rating schedule, but by providing thorough medical documentation and clearly articulating all of your knee’s symptoms—its range of motion limitations, its instability, and the pain it causes—you can help the VA fulfill its legal duty to maximize your well-deserved compensation. Understanding the specific, separate ratings available for a knee disability is the first and most critical step in securing the maximum possible compensation for which you are entitled.
