VA Disability Benefits for Knee Pain
Knee conditions are common among veterans. According to the Department of Veterans Affairs’ (VA’s) Annual Benefits Report for Fiscal Year 2020, limitation of flexion of the knee was the third most commonly claimed disability.
However, limitation of flexion of the knee is just one of the service-connected knee conditions for which VA offers compensation. Veterans can experience several types of knee pain, each of which is rated using different criteria.
How to Get Service Connected for Knee Pain
Direct Service Connection for Knee Pain
To establish direct service connection, veterans must provide evidence of the following:
- A diagnosis of a current knee condition by a medical professional;
- An in-service event, injury, or illness; and
- A medical nexus linking the current, diagnosed knee condition to the in-service event.
For example, say a veteran was playing basketball while serving on active duty and fell and hurt their knee. Following discharge from service, they were diagnosed with degenerative arthritis in their knee. If the knee condition can be traced back to the in-service injury, a doctor must provide an opinion linking the degenerative arthritis of the knee to the veteran’s in-service injury.
Secondary Service Connection for Knee Pain
A secondary service-connected condition is one that resulted from a separate condition that is already service-connected.
For example, say a veteran’s service-connected spine injury caused them to later develop knee injuries. Secondary service connection can be established if the veteran has a nexus connecting the two conditions.
Service Connection for Knee Pain by Aggravation
VA also compensates veterans for preexisting medical conditions “aggravated” by service.
Say for example a veteran entered service with a mild preexisting knee condition. Following service, the knee condition worsened in severity and now impacts their day-to-day life. In this case, the veteran’s service may have aggravated their preexisting knee condition beyond the natural progression of the disability. Therefore, they may be eligible for service connection based on aggravation.
VA Disability Ratings for Knee Pain
Once your knee condition is service connected, VA will assign a disability rating ranging between 0 and 100 percent. More serious and disabling knee injuries are assigned higher ratings.
Overall, VA ratings for knee pain depend on various factors, such as:
- The type of knee injury
- The severity of the diagnosed knee condition
- The knee’s range of motion
- The pain it causes
Common Knee Conditions and How VA Rates Them
Knee pain and knee-related conditions are typically rated under 38 CFR § 4.71a using different diagnostic codes. The following are several common knee conditions and how VA rates them.
Limitation of Flexion of the Knee – Diagnostic Code 5260
Limitation of flexion of the knee, the most common service-connected knee condition, refers to the range of motion of the knee as the veteran moves it or curls it inward towards the body.
Generally, VA strictly rates this condition based on the range of motion that exists as the veteran moves their knee in that direction rather than any pain it causes.
The most common rating VA assigns for limitation of flexion of the knee is 10 percent, although the highest rating a veteran can receive is 30 percent.
Limitation of Extension of the Knee – Diagnostic Code 5261
Limitation of extension of the knee refers to when the knee is not frozen but rather is limited in extension and cannot straighten all the way.
This knee pain condition is rated under diagnostic code 5261 and the disability ratings available are 0, 10, 20, 30, 40, and 50 percent. Typically, the greater limitation of extension (or the harder it is to straighten the knee), the higher the disability rating.
Similar to limitation of flexion of the knee, there are specific range of motion measurements that correspond with each disability rating. For example, if the leg can only straighten to within 45 degrees of being completely straight, then it is rated at 50 percent, whereas if it can only straighten to 10 degrees, it is rated at 10 percent.
Instability of the Knee – Diagnostic Code 5257
Instability of the knee refers to when the knee has too much motion from side to side or dislocates regularly. This condition can occur when damaged tendons and cartilage can no longer support the knee joint properly.
VA assigns a 0, 10, 20, or 30 percent disability rating for this knee condition based on the amount of instability present in the knee. To get a 30 percent rating, the knee must be so unstable that it gives out or dislocates on a regular basis.
Ankylosis of the Knee – Diagnostic Code 5256
Ankylosis, abnormal stiffening and immobility of the knee, can be assigned a 30, 40, 50, or 60 percent disability rating depending on the limitation of flexion. Again, the more limitation the veteran experiences, the higher the disability rating.
Total Knee Replacements – Diagnostic Code 5055
If the entire knee joint has been replaced by a prosthesis, then the total knee replacement is rated 100 percent for the first year following surgery.
After this one-year period, veterans will attend a Compensation and Pension (C&P) examination to determine the severity of their knee pain condition. Following the exam, veterans will be assigned a new rating based on the rating criteria outlined below.
If there is weakness and severe pain with motion, then the veteran’s knee condition is rated at 60 percent. If the pain is not severe but limits their range of motion, then it is rated under Diagnostic Code 5256, 5261, or 5262 based on the residual symptomology.
Importantly, the minimum rating for a total knee replacement is 30 percent – regardless of how much motion it has.
Partial Knee Replacements
Unlike total knee replacements, partial knee replacements do not have their own diagnostic code. Instead, partial knee replacements are rated according to any symptoms that are caused by the replacement, such as limitation of motion.
Can Veterans Receive Multiple Disability Ratings for Knee Pain?
Veterans can receive more than one disability rating for knee conditions as long as each condition involves different movements.
For example, if a veteran experiences difficulty in both bending and straightening their knee, they may be able to receive service-connected compensation for both limitation of flexion and extension.
However, in these cases it is important to avoid pyramiding – VA’s term for rating the same disability or same manifestation (i.e., symptom) of a disability twice.
TDIU for Knee Pain
If a veteran’s knee injury or condition does not qualify them for a 100 percent rating, they can apply for total disability based on individual unemployability (TDIU) if their knee pain prevents them from working. TDIU offers compensation at a 100 percent rate to veterans who are unable to secure or maintain substantially gainful employment due to their service-connected conditions.
Additional VA Rules for Knee Pain
VA’s Painful Motion Rule: 10% Ratings
VA’s regulations state that veterans should be afforded a 10 percent rating even if they do not necessarily meet the specific diagnostic code criteria for limited range of motion but can otherwise show they have painful motion.
However, VA often makes mistakes when it comes to this. VA is required to pay attention to other indicators of functional loss such as weakness, interference with sitting and standing, pain during motion, and fatigability. If VA does not take such factors into consideration, veterans should consider appealing for a higher disability rating.
VA’s Bilateral Factor Rule: When Both Knees Have Disabilities
VA recognizes that if veterans have a disability that affects both knees, the ability to function on daily basis is going to be even more limited. In this case, VA will combine the ratings of the left and right knees and add an additional 10 percent.
For example, if a veteran had a 20 percent rating in their right knee for limitation of flexion and a 10 percent rating in their left knee for instability, VA will first take those two ratings and combine them to get a total of 28 percent. From there, VA will take 10 percent from that 28 percent (i.e., 2.8 percent) and add it to the 28 percent. The new combined rating would be 31 percent (or 30 percent based on the rounding).
In this specific example, the veteran’s combined disability rating does not change, but in other cases, this bilateral factor can be the difference between a 20 and 30 percent combined rating, a 90 and 100 percent combined rating, etc.
VA’s Functional Loss Rule
VA should also evaluate functional loss when rating a veteran’s knee condition. Functional loss refers to how the condition affects the veteran’s ability to function in daily life.
This test considers factors such as pain, how severe the condition is during flare-ups, and how frequently flare-ups occur. Even if a veteran has full range of motion, if they are in so much pain that they cannot function, then this should be accounted for in their disability rating.
VA’s Major Joint Rule and Arthritis of the Knees
VA’s major joint rule basically says that if a veteran has a diagnosis of arthritis of the knees, VA should apply the normal range of motion tests and determine if the veteran qualifies for a disability rating under Diagnostic Codes 5260 or 5261. However, if VA completes the range of motion testing and determines the veteran has a good range of motion overall but still experiences pain, VA will apply Diagnostic Code 5003 for arthritis.
If a veteran has confirmation of arthritis through x-ray evidence, VA should assign either a 10 or 20 percent disability rating based on the severity of the arthritis and whether it affects one or both knees. This allows VA to maximize the veteran’s benefits.
How to Use Lay Evidence for Knee Pain
Lay evidence includes statements from veterans, veterans’ friends and family members, and fellow service members.
Veterans can use lay statements to outline the onset and progression of their knee condition. They can also describe its severity and how it affects daily life. Lay evidence can be very helpful when a veteran lacks certain medical evidence.
Tips for C&P Exams for Knee Pain
C&P exams for knee pain and related conditions are primarily based on range of motion.
Range of motion should be tested after repetitive motion to determine how limited motion is following prolonged use. C&P examiners should also ask veterans about flare-ups and how they affect their functioning. Finally, C&P examiners should address functional loss due to pain. If C&P examiners do not address these issues, the exam may be inadequate for rating purposes.
It is important for veterans to be upfront and honest about limitations caused by their knee pain and report any functional loss they experience. If they do not report their symptomatology, VA may not fully comprehend the severity of the condition.
Additionally, if veterans believe their C&P exam results were unfavorable, they can submit contrasting evidence.
