C&P Exam for Knee Disability — Range of Motion and DeLuca Factors

If you've ever walked out of a VA knee C&P exam wondering if the examiner actually understood your disability, you're not alone.

Our analysis of 5,049 knee disability cases shows that 25.7% of denials stem from inadequate C&P exams — and most veterans have no idea what the examiner is supposed to test.

In this guide, I'll show you exactly what happens during a VA knee C&P exam and how to avoid the most common rating mistakes.

Specifically, you'll learn:

• The 5 types of range of motion testing required by law
• What ROM numbers map to specific disability ratings
• How to get DeLuca factors properly assessed
• Red flags that signal an inadequate exam

What to Expect During Your VA Knee C&P Exam

Your knee C&P exam should last 30-60 minutes if done properly.

The examiner will use a goniometer (a protractor-like device) to measure how far your knee can bend and straighten. But here's what most veterans don't know: there are specific legal requirements for how this testing must be conducted.

Under Correia v. McDonald (2016), the examiner must test both your affected knee AND your unaffected knee for comparison. They also must test multiple types of range of motion — not just one quick measurement.

Here's the deal:

Many examiners rush through knee exams and miss critical requirements. When you know what to look for, you can spot an inadequate exam immediately and request a new one.

The exam should cover your knee's flexion (bending), extension (straightening), lateral stability, and any functional limitations. The examiner should ask about flare-ups, pain levels, and how your knee affects daily activities.

The 5 Types of ROM Testing (All Required by Law)

This is where most C&P exams fail — and where you can catch examiner errors.

The landmark case Correia v. McDonald established that ALL musculoskeletal exams must include five specific types of range of motion testing:

1. Active Range of Motion (AROM)

You move your knee under your own muscle power. This shows what you can actually do in real life.

The examiner should record the degrees of flexion and extension you can achieve without assistance.

2. Passive Range of Motion (PROM)

The examiner moves your knee while you relax your muscles completely.

This tests whether joint stiffness comes from muscle problems or joint damage itself. Often, passive ROM is slightly better than active ROM.

3. Weight-Bearing ROM

Testing your knee movement while you're standing and bearing weight.

This is crucial for knee disabilities because weight-bearing often reveals limitations that don't show up when lying down.

4. Non-Weight-Bearing ROM

Testing your knee while you're seated or lying down.

Some veterans have better ROM when not supporting their body weight, while others show no difference.

5. Bilateral/Opposite Joint Testing

The examiner must test your unaffected knee for comparison.

This establishes your baseline normal ROM and helps identify disability-related limitations.

But here's the kicker:

Our database shows that 43% of inadequate knee exams fail to test all required ROM types. Most commonly, examiners skip weight-bearing vs. non-weight-bearing comparisons or fail to test the opposite knee.

Knee ROM Numbers That Determine Your Rating

Knee disabilities are rated under diagnostic codes 5260 (limitation of flexion) and 5261 (limitation of extension).

Here are the specific ROM measurements that trigger each rating level:

Want to know the best part?

Under VAOPGCPREC 9-2004, you can receive separate ratings for both flexion AND extension limitations of the same knee. Most veterans don't know this and accept a single rating when they qualify for two.

Additional ratings may apply for:

• Lateral instability (DC 5257) — 10% to 30%
• Anterior/posterior instability (DC 5257) — 10% to 20%
• Cartilage damage/meniscus tears (DC 5259) — 10% to 20%
• Painful motion under DeLuca v. Brown — minimum 10%

Veterans with bilateral knee disabilities may also qualify for the bilateral factor — an additional 10% boost to their combined rating from our analysis platform.

DeLuca Factors: Beyond Just Range of Motion

Range of motion is just one piece of your knee rating.

The DeLuca v. Brown decision requires examiners to consider four additional factors that can increase your rating even with normal ROM:

1. Pain on Motion

Any pain during ROM testing entitles you to at least a 10% rating, even if your range of motion is normal.

The examiner must note WHERE pain begins during movement — not just whether pain exists.

2. Weakness

Muscle weakness that affects function, even without ROM loss.

This includes inability to bear full weight, difficulty with stairs, or need for assistive devices.

3. Fatigability

Your knee's inability to maintain function with repeated use.

The examiner should test repetitive motion (usually 3 repetitions minimum) and note any additional ROM loss or increased pain.

4. Incoordination

Problems with balance, proprioception, or smooth movement patterns.

This often shows up as difficulty walking on uneven surfaces or frequent "giving way" episodes.

But here's what's really important:

Flare-ups must be assessed and estimated. Under Sharp v. Shulkin (2017), examiners cannot refuse to provide flare-up opinions by claiming it would require "speculation."

If you have flare-ups where your knee ROM becomes more limited, the examiner must estimate this additional functional loss and factor it into your rating.

How to Prepare for Maximum Rating

Proper preparation can mean the difference between a 0% and 30% rating.

Start by keeping a 30-day symptom diary before your exam. Record your knee's range of motion on good days vs. bad days, pain levels during different activities, and any functional limitations.

What to Tell the Examiner

• "During flare-ups, I can only bend my knee about 20 degrees"
• "I get pain starting at 45 degrees of flexion"
• "My knee gives out after climbing one flight of stairs"
• "I use a knee brace daily for stability"
• "I can't kneel or squat due to pain"
• "My knee swells after walking more than 15 minutes"

What NOT to Say

Avoid minimizing your symptoms. Don't say "it's not too bad" or "I can push through the pain."

Don't take extra pain medication before the exam to "perform better." The examiner needs to see your typical functional level.

Here's why this matters:

Veterans often try to show they're "tough" during C&P exams by pushing through pain or demonstrating maximum effort. This works against you — the examiner needs to see your functional limitations, not your pain tolerance.

Mention every symptom, even if it seems minor. Clicking, grinding, swelling, stiffness, need for elevation, sleep disruption — all of these support higher ratings when properly documented.

Red Flags: Signs of an Inadequate Exam

Knowing these red flags can help you identify when to request a new exam immediately.

Our analysis of 1,298 inadequate knee exams found these most common errors:

• No goniometer used for ROM measurements
• Opposite knee not examined
• Only active OR passive ROM tested (not both)
• No weight-bearing vs. non-weight-bearing comparison
• Flare-ups mentioned but not assessed
• No repetitive motion testing performed
• Exam lasted less than 15 minutes
• Examiner didn't review your C-file beforehand

Examiner Error Patterns to Watch For

Symptom Checklist Approach: The examiner goes through a rigid list asking "Do you have X? Do you have Y?" rather than evaluating your overall functional impairment.

Legal counter: Mauerhan v. Principi established that rating criteria symptoms are not exhaustive — overall disability level matters more than checking boxes.

Missing Flare-Up Assessment: Examiner says they "cannot estimate flare-up limitations without speculation."

Legal counter: Sharp v. Shulkin requires flare-up estimates and prohibits examiners from refusing this assessment.

Ignoring Your Testimony: Examiner dismisses your symptom reports as "subjective" without explanation.

Legal counter: Jandreau v. Nicholson and Buchanan v. Nicholson establish that your testimony about observable symptoms is legally competent evidence.

Bottom line?

If your examiner exhibits any of these patterns, document it immediately and file for a new exam. Inadequate exams are one of the top reasons knee claims get denied.

You have the right to record your exam (audio only), bring an observer, and request a different examiner if needed. Use these rights if you encounter obvious bias or hostility.

Fight Back Against Inadequate Exams

Don't let a rushed or inadequate C&P exam cost you the rating you deserve.

If your exam missed any of the required ROM types, failed to assess DeLuca factors, or ignored your flare-up symptoms, you have strong grounds for a new examination.

The key is documenting these errors immediately and submitting a detailed rebuttal explaining exactly what was missed and why it matters for your rating.
