Here’s a quick-reference summary of the most common VA knee ratings under 38 CFR § 4.71a:

Knee disabilities are among the most common VA claims. Over 1.3 million veterans currently receive compensation for knee and lower leg conditions. In fact, limitation of flexion of the knee was the second-most commonly claimed VA disability as of fiscal year 2024.

The VA rates these conditions under 38 CFR Part 4, the Schedule for Rating Disabilities, specifically the musculoskeletal system section. Ratings are based on functional loss — how much your knee condition limits your ability to work and carry out daily activities — not just raw measurements alone.

I’m Larry Fowler, publisher of the USMilitary.com Network since 2007 and a longtime resource for veterans navigating VA benefits, including the 38 CFR knee rating chart for VA disability. In this guide, I’ll break down every major diagnostic code, rating threshold, and special rule you need to know to pursue the rating you’ve earned.

Understanding the 38 CFR Knee Rating Chart VA Disability

When we look at how the VA evaluates your knees, we have to start with the “Rule Book”: 38 CFR Part 4. Specifically, Section 4.71a contains the Title 38 Schedule of Ratings for the musculoskeletal system.

The VA doesn’t just ask “Does it hurt?” They measure exactly how much your knee can move using a tool called a goniometer. This is a specialized protractor that an examiner uses during a Compensation and Pension (C&P) exam to measure your Range of Motion (ROM). These measurements are then matched against the 38 cfr knee rating chart va disability to determine your percentage. These percentages correlate to your monthly benefit amount, which you can track on the VA Disability Paychart 2026.

The two primary ways the VA measures movement are Flexion (bending the knee inward) and Extension (straightening the leg out).

Limitation of Flexion (DC 5260) in the 38 CFR Knee Rating Chart VA Disability

Flexion is the act of bending your knee toward your body. A normal knee has a flexion range of about 0 to 140 degrees. If your service-connected injury prevents you from bending your knee fully, you fall under Diagnostic Code (DC) 5260.

Because so many veterans spent years jumping out of trucks, carrying heavy packs, or performing high-impact maneuvers, this is one of the Top 10 VA Disability Claims filed every year.

• 10% Rating: Flexion is limited to 45 degrees.
• 20% Rating: Flexion is limited to 30 degrees.
• 30% Rating: Flexion is limited to 15 degrees.

It is important to remember that these ratings apply even if you can physically move the knee further but experience functional loss due to pain, weakness, or “flare-ups” that effectively stop your movement at these thresholds.

Limitation of Extension (DC 5261) in the 38 CFR Knee Rating Chart VA Disability

Extension is the ability to straighten your leg. If your knee gets “stuck” and you can’t straighten it all the way, it’s often more disabling than a flexion issue because it affects your gait and balance. This is covered under DC 5261 and is a staple on the List of VA Disability Conditions.

• 10% Rating: Extension limited to 10 degrees.
• 20% Rating: Extension limited to 15 degrees.
• 30% Rating: Extension limited to 20 degrees.
• 40% Rating: Extension limited to 30 degrees.
• 50% Rating: Extension limited to 45 degrees.

The more “bent” your knee remains (the higher the degree of limited extension), the higher the rating you receive because the disability is more severe.

Knee Instability, Meniscus Tears, and Ankylosis Ratings

Beyond just how the knee bends, we have to look at how stable it is. If your knee “gives out” or feels like it’s sliding out of place, you are dealing with instability or recurrent subluxation.

Knee Instability (DC 5257)

In February 2021, the VA updated the rules for DC 5257. Previously, ratings were based on vague terms like “slight,” “moderate,” or “severe.” Now, the 38 CFR knee rating chart that VA disability uses uses more objective criteria based on whether a doctor has prescribed assistive devices.

• 10% Rating: You have instability but don’t require a prescribed brace or assistive device.
• 20% Rating: A medical professional has prescribed a brace for your instability.
• 30% Rating: You have a prescription for both a knee brace and an assistive device (like a cane, crutch, or walker).

If your condition has worsened since your last exam, you may want to look into how to Increase VA Disability Rating by submitting new evidence of these prescriptions.

Meniscus and Cartilage (DC 5258 & 5259)

The “cushion” in your knee is called the meniscus.

• DC 5258: Covers “cartilage, semilunar, dislocated” with frequent episodes of “locking” and pain. This typically warrants a 20% rating.
• DC 5259: Covers the removal of the semilunar cartilage (meniscectomy). If you’ve had the cartilage removed and still have symptoms, you may qualify for a 10% rating.

Knee Ankylosis (DC 5256)

Ankylosis occurs when the knee joint is totally stiff and cannot move at all. This is rated based on the angle at which the knee is frozen.

• 30% Rating: Favorable angle (usually near full extension).
• 60% Rating: Unfavorable angle (frozen in a way that makes walking extremely difficult).

You can find the full legal definitions for these in the 38 CFR Part 4 Musculoskeletal System regulations.

Special Rules: Pyramiding, Flare-ups, and the Amputation Rule

The VA has several “hidden” rules that can significantly change your rating. We want to make sure you understand these so you don’t leave money on the table.

The DeLuca Factors and Painful Motion

Under 38 CFR § 4.59, known as the “Painful Motion Rule,” if you have pain when moving a joint, the VA is supposed to grant at least a minimum compensable rating (usually 10%), even if your range of motion is technically “normal.”

Furthermore, the DeLuca v. Brown court case established that examiners must consider functional loss. This means they must account for:

• Weakness
• Fatigability (the knee getting tired after repeated use)
• Incoordination
• Flare-ups: If your knee is “okay” on the day of the exam but becomes useless twice a week, the examiner must estimate your ROM during those bad days.

Pyramiding

“Pyramiding” is the VA term for getting paid twice for the same symptom. Generally, you cannot get two ratings for the same manifestation. However—and this is a big “however”—the VA allows separate ratings for the knee if they represent different types of disability. For example, you can often receive one rating for limitation of motion (DC 5260/5261) and a separate rating for instability (DC 5257) because they are different problems.

The Amputation Rule

This rule (38 CFR § 4.68) states that the combined rating for a limb cannot exceed the rating that would be given if the limb were actually amputated. For a lower leg disability, the “cap” is usually the 40% or 60% rating associated with various levels of leg amputation.

Other Notable Codes

• Leg Shortening (DC 5275): If one leg is shorter than the other due to service-connected injury, ratings range from 0% to 60% (for shortening over 4 inches).
• Knee Hyperextension (DC 5263): Known as genu recurvatum, this is rated at 10% if it is symptomatic.

Understanding What Conditions Qualify for Veteran Disability Benefits helps you identify these secondary issues that often accompany a primary knee injury.

VA Ratings for Knee Replacement and Resurfacing (DC 5055)

If your knee is so damaged that you require a total knee replacement or resurfacing, the VA provides a specific path under DC 5055.

1. The 100% Temporary Rating: Following a total knee replacement, the VA grants a temporary 100% disability rating. Under current rules, this lasts for four months following the surgery (though some older cases may see longer periods). This is intended to cover your convalescence and rehab.
2. The Minimum Rating: Once the 100% period ends, the VA will re-evaluate you. The minimum rating for a total knee replacement is 30%. You will never drop below this as long as the replacement is in place.
3. Higher Ratings for Residuals: If you still have “severe” painful motion or weakness after the surgery, the VA can assign a 60% rating.

Partial knee replacements are handled differently; they are usually rated based on the residual limitation of motion rather than the automatic 30% minimum given to total replacements. You can check how these percentages translate to dollars at the 2025 VA Disability Rates page.

Frequently Asked Questions about VA Knee Ratings

Can I get separate ratings for instability and range of motion?

Yes. As we mentioned in the section on pyramiding, the Board of Veterans’ Appeals (BVA) has consistently ruled that instability (DC 5257) and limitation of motion (DC 5260 or 5261) are distinct disabilities.

For example, in Citation Nr: 21064338, a veteran was awarded a 30% rating for flexion limitation and a separate 20% rating for instability in the same knee. If both knees are affected, the VA also applies the Bilateral Factor, which adds an extra 10% to your combined rating for those limbs. This is a very different process than filing for something like VA Disability for Sleep Apnea, which is usually rated as a single entity.

How does the VA rate shin splints and knee pain?

Shin splints (Medial Tibial Stress Syndrome) are rated under DC 5262.

• If you have shin splints in both legs that don’t respond to surgery, you could be rated at 30%.
• The minimum compensable rating is 10%.
  Since the tibia and fibula connect directly to the knee joint, shin splints often cause “pain with motion” that can affect your overall knee rating. This is a physical condition, but chronic pain can also lead to secondary issues, much like the way a VA Disability Rating for PTSD can be linked to physical trauma.

What evidence is needed for a 30% instability rating?

To hit that top 30% mark for instability under the new rules, you need:

1. Medical Evidence: A diagnosis of a ligament tear or recurrent subluxation.
2. Prescriptions: Documentation that a doctor has prescribed both a knee brace and an assistive device (cane, walker, or crutches).
3. Nexus: A “nexus letter” linking the instability to your time in service.
4. Lay Statements: Statements from you or your family describing how your knee “gives out” during daily activities.

While some veterans choose to use VA Disability Lawyers, many find that having a complete Disability Benefits Questionnaire (DBQ) from their own doctor is the strongest evidence they can provide.

Conclusion

Navigating the 38 CFR knee rating chart for VA disability doesn’t have to feel like learning a foreign language. At USMilitary.com, we want to ensure you have the tools to speak the VA’s language—specifically the language of “Diagnostic Codes” and “Functional Loss.”

The VA is legally required to give you the “Benefit of the Doubt” when the evidence is equally balanced. If your knee pain makes it hard to stand, walk, or work, don’t settle for a 0% non-compensable rating. Ensure your examiner uses a goniometer, accounts for your flare-ups, and documents any need for braces or canes.

Whether you are looking for VA Disability Rating Charts 2025 or trying to establish a service connection for the first time, stay persistent. Your knees carried you through your service; now, let the benefits you earned carry you through your retirement.
