We see a lot of knee arthritis claims where X-rays confirm the condition and pain is documented, but when the VA rates the knee, the file doesn’t fully show how it holds up with use, weight-bearing, or over time, and that’s usually what keeps the rating lower than it should be.
Quick Answer
Knee arthritis ratings are based on limited motion, painful motion, and how the knee functions with use over time. Higher evaluations usually depend on whether the record clearly shows reduced movement, flare-ups, instability, or worsening function beyond a single exam measurement. criteria.

How Does the VA Rate Knee Arthritis?
The VA rates knee arthritis based on function, not just imaging, and that usually starts with range of motion. How far the knee bends, how far it straightens, and when pain begins during movement are all part of the baseline picture.
From there, the VA can also consider how the knee performs beyond that snapshot, including weakness, painful use, flare-ups, swelling, and whether movement gets worse after repetition or weight-bearing. This is important because your knee may move one way in the exam room and very differently after normal use.
Most exams capture the measurement, but not what happens after walking, standing, or using the knee repeatedly, or how movement changes during flare-ups, so the rating often ends up based on what was recorded in that moment rather than how the knee actually performs across a normal day.
That gap is where most knee arthritis claims often stay lower than the condition feels in real life.
What Determines How a Knee Arthritis Claim Gets Rated
Knee arthritis claims don’t move based on a diagnosis alone. They move based on what the file makes clear over time.
Gets Rated Higher
Files that rate higher show more than pain. They show consistent limits with movement, walking, standing, stairs, kneeling, or repeated use, and the record reflects that those problems continue instead of appearing once.
When the file reads as limited or manageable
Files that stay low usually confirm arthritis and mention symptoms, but they do not clearly show what those symptoms lead to. Without documented loss of motion, functional limits, instability, or flare-up impact, the condition often reads as mild.
The Gap Most MST Files Miss
The gap is usually not the diagnosis. It is the difference between having arthritis and clearly showing how arthritis changes what the knee can do in real life. If that part is weak in the file, the rating often stays lower than expected.
What VA Rating Percentages Apply to Knee Arthritis?
Knee arthritis is usually rated through limitation of motion, painful motion, instability, meniscus problems, or other knee findings supported by the record. The final percentage depends on which symptoms are documented and whether separate ratings can be assigned without overlapping the same limitation twice.
| Rating | What the VA Is Looking At | What Your Records Need to Show |
|---|---|---|
| 10% | Painful motion or mild limitation | Pain with movement, confirmed arthritis, or motion loss that does not meet higher criteria |
| 20% | More significant motion loss | Clear reduction in flexion or extension, worsening pain with use, or another separately ratable knee issue |
| 30% | Severe limitation under a primary knee code | Marked motion loss, qualifying instability, or significant knee impairment under the applicable code |
| Higher Ratings | More than one distinct knee problem | Limitation of motion plus instability, meniscus conditions, surgical residuals, or replacement ratings when supported |
Important:
Knee ratings are often more about how the symptoms are coded than the arthritis label itself.
What Makes a Knee Arthritis Rating Go Higher?
Higher ratings usually come from files that show more than pain.
The stronger claims document how movement changes after repeated use, how flare-ups reduce function, and how the knee affects walking, standing, stairs, kneeling, balance, work tasks, or a normal routine. They also stay consistent over time instead of appearing once and disappearing from the record.
When the evidence clearly shows that the knee does less than it used to, and keeps doing less over time, the rating has a stronger basis to move higher.
What Happens at a C&P Exam for Knee Arthritis?
The C&P exam is where many knee arthritis ratings are shaped because this is where movement is measured and functional limits are discussed.
The examiner will usually test bending, straightening, pain during motion, and repeated-use movement. They may also ask about flare-ups, instability, braces, walking limits, standing tolerance, and how the knee affects work or daily activity.
Where claims lose ground is when the exam only captures what the knee can do in that moment, while the file never clearly explains what happens after use or on worse days.
Be specific. If the knee swells after walking, gives out on stairs, stiffens after sitting, or moves less during flare-ups, that matters because it helps document functional loss beyond a single measurement.
Before your exam, think in specifics. Not just symptoms, but what they’ve caused. Missed work, pulling away from people, trouble keeping up, changes in behavior over time, etc.
What to Check Before Filing or Appealing a Knee Arthritis Claim
Before filing, look at your file the way a rater will.
Not just what is in it, but what it clearly shows when everything is put together.
- Does the record document limited motion, or only pain?
- Does it explain what happens after walking, standing, stairs, or repeated use?
- Are flare-ups described with specifics about loss of movement or function?
- Is instability, buckling, swelling, or brace use documented?
- Does the C&P exam reflect how the knee performs on bad days, not just that moment?
- Does the file show how the knee affects work, mobility, or daily activity over time?
Most knee arthritis claims that stall are not missing everything. They are missing one or two of these links. Once you identify the gap, it becomes much clearer what needs to be strengthened before you file or appeal.
What Are Secondary Conditions To Knee Arthritis
Knee arthritis often changes how a person walks, stands, shifts weight, and moves through the day. Over time, that can place added stress on other parts of the body or contribute to new limitations that may be separately claimable when medically supported.
Common secondary conditions claims include:
Hip Condition & Arthritis
Years of altered gait from a bad knee can shift stress into the hips and contribute to pain, limited motion, or degeneration.

Back Pain & Musculoskeletal
Favoring one knee often changes posture and gait mechanics, which can place added stress on the lower back over time.
Learn more →Depression
Long-term pain and reduced mobility can affect mood, motivation, relationships, and daily functioning when clearly documented.
Learn more →Anxiety Disorder
Persistent pain, instability, and limits on activity can increase stress, worry, and avoidance over time.
Learn more →Sleep Disorders
Knee pain can interfere with sleep position, recovery, and daytime function when the disruption is consistent in the record.
Learn more →Chronic Pain Syndrome
When pain becomes persistent and affects multiple areas of life, it can change the overall functional picture of the claim.

Example:
A veteran with service-connected knee arthritis develops chronic hip pain after years of favoring one side while walking. When the medical evidence clearly connects the altered gait to the hip condition, that secondary claim may have a path forward.
Why Your Knee Arthritis VA Rating Might Be Lower Than Expected
A lot of veterans expect the diagnosis itself to drive the rating, but the VA is focused on what the knee can do and what the record supports.
If the file confirms an arthritis condition but does not clearly show motion loss, repeated-use limits, flare-ups, instability, or day-to-day functional impact, the rating often comes in lower than expected.
That does not always mean the condition is mild. It often means the record did not fully capture how the knee behaves under real use.
What a Strong Knee Arthritis Claim Looks Like
A strong knee arthritis claim usually tells a complete functional story.
The diagnosis is confirmed. Motion limits are documented. Pain with use is consistent. Flare-ups are described. The record shows how walking, stairs, standing, kneeling, balance, or work tasks are affected over time.
When those pieces line up, the VA has a clearer basis to assign the right rating.
What This Usually Comes Down To
Knee arthritis claims are often won or lost in the gap between having the condition and clearly showing how it limits function.
Most files are not missing everything. They are missing specific details about movement, repeated use, flare-ups, instability, or how the knee affects normal activity. Once those gaps are identified and documented, the path forward usually becomes much clearer.

FAQs About VA Rating for Knee Arthritis
What is the VA rating for knee arthritis?
Most knee arthritis ratings fall between 10% and 60%, depending on limitation of motion, painful motion, instability, and whether separate knee symptoms can be rated.
Can I get a VA rating for knee arthritis with normal X-rays?
Sometimes yes. Functional loss, painful motion, and other knee findings can still matter, though imaging often helps support the claim.
Can both knees be rated separately?
Yes. Each knee can be rated based on its own symptoms and limitations.
Can knee instability be rated separately from arthritis?
In some cases, yes. Separate ratings may be possible when symptoms are distinct and supported by the evidence.
What helps increase a knee arthritis VA rating?
Clear documentation of reduced motion, flare-ups, repeated-use limits, instability, and day-to-day functional impact often helps more than diagnosis alone.
Can knee arthritis be secondary to another service-connected condition?
Yes. Knee arthritis may be linked secondarily depending on gait changes, prior injuries, or other service-connected orthopedic issues when medically supported.
What is the VA disability rating for knee arthritis?
The VA disability rating for knee arthritis depends on how the condition affects function, not just the diagnosis itself. Ratings are commonly based on painful motion, limited range of motion, instability, flare-ups, and whether separate knee symptoms can be rated under different diagnostic codes.
How is arthritis in the knee rated by the VA?
Arthritis in the knee is rated by looking at how the joint moves and performs over time. The VA often considers bending, straightening, pain during motion, repeated-use limits, flare-ups, instability, and how the knee affects walking, standing, stairs, or daily activity.
