⚖️ Regulatory Basis

Knee ratings governed by 38 CFR § 4.71a: DC 5260 (limitation of flexion of the leg) and DC 5261 (limitation of extension of the leg). Additional codes may apply: DC 5257 (instability), DC 5258 (loose bodies), DC 5263 (ankylosis). The C&P exam uses the Knee and Lower Leg DBQ.

Why the Knee C&P Exam Determines Your Rating

The knee is the second most commonly claimed VA disability condition, trailing only lower back conditions. Approximately 20% of VA disability claims involve knee pathology — reflecting the relentless physical demands of military service: running in boots on hard surfaces, carrying heavy loads, jumping from vehicles, performing ruck marches, and direct trauma in training or combat.

Unlike conditions rated primarily on symptom severity (like PTSD or migraines), knee ratings are driven almost entirely by objective, measurable findings — particularly range of motion (ROM) in degrees. The C&P exam is the mechanism through which those measurements are captured. A well-prepared veteran who communicates their full impairment clearly can receive a substantially different rating than an unprepared one.

What the Examiner Will Test

The VA examiner for a knee claim will use the Knee and Lower Leg DBQ to document findings. This questionnaire covers multiple domains — and understanding each one helps you prepare. The exam typically lasts 20–45 minutes and includes both physical testing and a medical history interview.

Physical Testing Components

Range of Motion: The Numbers That Drive Your Rating

Under DC 5260 (limitation of flexion) and DC 5261 (limitation of extension), your rating is determined almost entirely by how many degrees of motion you have left. Understanding the normal ranges and rating thresholds before your exam is essential.

📐 Normal Knee Range of Motion

Normal flexion: 0° to 140° (or greater) — the ability to bend the knee from fully straight to deeply bent

Normal extension: 0° (fully straight leg) — the ability to straighten the knee completely from a bent position

Key principle: The VA uses your painful motion point as the functional limit, not just your absolute maximum. If pain begins at 85° of flexion, the VA should rate you at the 85° tier even if you can push through to 100°. Always tell the examiner where pain starts.

20%Limited to 15°$346.95
10%Limited to 10°$175.51

Important: Under the painful motion rule at 38 CFR § 4.59, if your knee joint is painful on motion, the VA must rate you at least at the minimum compensable level for that body part — even if your ROM technically falls outside the table. Make sure the examiner documents pain, not just ROM degrees.

Additionally, the VA must consider functional loss due to flare-ups under 38 CFR § 4.40. If your knee is worse on bad days than on exam day, tell the examiner. They should ask about your worst-day ROM, not just your exam-day ROM.

Repetitive Motion & Fatigue: The DeLuca Factor

One of the most powerful — and most overlooked — tools in knee C&P exam preparation is the DeLuca v. Brown (1995) repetitive motion principle. The CAVC held in DeLuca v. Brown, 8 Vet. App. 202 (1995), that the VA must consider the effect of repetitive use on a joint's range of motion when rating musculoskeletal conditions under 38 CFR Part 4.

The three regulatory provisions that together form the DeLuca framework are:

💡 The DeLuca Principle in Practice

Under DeLuca, the VA cannot simply measure your knee's maximum ROM at one point in time and assign a rating. The examiner must consider what happens to your knee after repetitive use — after walking a block, going up and down stairs, or performing any sustained activity. If your knee's effective ROM decreases after repeated motion (due to pain, swelling, fatigue, or weakness), that reduced "after-repetition" ROM is the relevant measurement for rating purposes.

What this means for your exam: Tell the examiner how your knee functions after activity, not just at rest. If your knee tightens up after walking, say so. If you have significantly more difficulty bending your knee at the end of a work day versus the morning, that information belongs in the record — and the examiner is required to document and consider it.

How to Communicate the DeLuca Factor at Your Exam

When the examiner tests your ROM, they may measure your initial (resting) motion. Under the DeLuca framework, you should proactively provide information about post-activity ROM and function. Consider statements like:

Under 38 CFR § 4.45, the examiner must document weakened movement, excess fatigability, incoordination, and pain on movement — not just the maximum arc of motion. If these factors are not documented in your C&P DBQ, it may be grounds for an inadequate exam objection in a subsequent appeal.

Secondary Conditions Check: What Your Knee May Be Causing

A service-connected knee condition frequently causes secondary conditions through biomechanical compensation — altered gait, reduced activity, and chronic pain. At your C&P exam, mention any of the following if they apply:

Each secondary condition you identify and claim creates an additional rating that combines with your primary knee rating — multiplying the monthly benefit value of your claim.

Stability & Special Tests: Lachman, Drawer, Varus/Valgus

Beyond ROM, the examiner will perform specific orthopedic tests to assess ligament and meniscal integrity. These tests can support separate ratings under DC 5257 (recurrent subluxation or lateral instability) and may uncover pathology not visible on standard X-ray.

Lachman Test (ACL Integrity)

The examiner flexes your knee to approximately 30° and attempts to translate the tibia anteriorly on the femur. Excessive anterior movement indicates ACL insufficiency or laxity. ACL injuries are common in military training — landing from jumps, pivoting under load, vehicle accidents. If you've had an ACL injury (surgical or non-surgical), Lachman test findings document residual laxity.

Anterior and Posterior Drawer Tests

With the knee at 90°, the examiner pulls the tibia forward (anterior drawer — ACL) and pushes it backward (posterior drawer — PCL). Positive tests indicate ligamentous laxity or instability. In Veterans Claims, documented ligamentous instability can support a separate DC 5257 rating on top of your range-of-motion rating.

Varus/Valgus Stress Tests (Collateral Ligaments)

The examiner applies medial and lateral stress to test the MCL (medial collateral ligament) and LCL (lateral collateral ligament). LCL injuries from lateral blows to the knee (combat, vehicle, PT accidents) are common in veterans. Documented instability supports higher ratings and may open a DC 5257 claim.

McMurray Test (Meniscus)

The examiner rotates the foot while flexing and extending the knee. Pain or a "click" with this test suggests meniscal pathology. Meniscal tears are among the most common knee injuries in service members — including those caused by repetitive loading rather than a single traumatic event.

How VA Rates Knee Conditions: DC 5260 vs DC 5261

DC 5260 — Limitation of Flexion

Max 30%

Rates the inability to fully bend the knee. Most common knee rating code. Maximum 30% for flexion limited to 30° or less.

DC 5261 — Limitation of Extension

Up to 50%

Rates inability to fully straighten the knee (flexion contracture). Higher maximum — up to 50% for extension limited to 45°. More disabling than flexion loss.

DC 5257 — Recurrent Subluxation

Up to 30%

Rates lateral instability. Can be rated separately from ROM codes. 10% mild, 20% moderate, 30% severe instability. Can be combined with ROM codes.

DC 5258 — Loose Bodies

10%

Cartilaginous loose bodies in the knee causing locking, extreme tenderness, and pain. Usually accompanied by ROM limitations rated under 5260/5261.

DC 5263 — Ankylosis

Up to 60%

Complete fusing of the knee joint. Rare but possible after severe injury or surgery. Rated on position of fixation (favorable vs. unfavorable angle).

Bilateral Factor

+10% add-on

If both knees are service-connected, you get a 10% bilateral factor added to the combined rating. File both knees even if one is worse.

Anti-pyramiding rule: You cannot be rated under both DC 5260 AND DC 5261 for the same knee at the same time — they're alternative codes for the same condition. However, you CAN be separately rated under DC 5257 (instability) in addition to DC 5260 or 5261.

How to Prepare for Your Knee C&P Exam

Preparation is the difference between a rating that reflects your actual impairment and one that captures you on a good day. The exam may be scheduled with 2–4 weeks notice — use that time well.

Gather Your Medical Records

Document Your Baseline Pain Level

Before the exam, write down your typical daily pain level on a 0–10 scale, your pain on bad days, and what activities trigger or worsen the pain. Be specific:

Note Functional Limitations

The VA must document functional loss — not just degrees of motion. Before your exam, prepare a mental list of activities your knee prevents or limits:

What to Wear

Wear loose-fitting pants or shorts that allow easy access to your knee. You'll need to bend, extend, and have the examiner physically test your joint. Athletic shorts or sweatpants work well. Avoid tight jeans that restrict movement — they may artifically limit your ROM during the exam.

Do NOT Take Extra Pain Medication Before the Exam

This is critical: do not take more pain medication than usual before your C&P exam in an attempt to manage the discomfort. If your pain is masked by medication, the examiner may see more motion than you typically have, resulting in a lower rating. Take your usual medications on your usual schedule — nothing more.

Common Mistakes Veterans Make at Knee C&P Exams

These mistakes cost veterans rating points — sometimes for years:

1. Minimizing Symptoms ("I Can Push Through It")

Military culture teaches veterans to be stoic and minimize pain. At a C&P exam, this hurts you. The examiner documents what you report. If you say "it's not that bad" when you mean "it's manageable with significant effort and constant pain," the record will reflect the former. Be medically honest — describe your actual experience, including how pain impacts your daily life.

2. Showing Up on a "Good Day" Without Flagging It

Knee conditions fluctuate. If your exam falls on a day when your symptoms are atypically mild, say so: "Today is actually a relatively good day for me. On average, I'd describe my pain as..." This protects you from a low rating based on an unrepresentative snapshot. The VA must consider flare-up severity under 38 CFR § 4.40.

3. Not Reporting All Symptoms

Many veterans focus only on pain and forget to mention: instability (giving way), locking, swelling, crepitus, weakness, or sleep disruption. The examiner documents what you mention. If you don't mention it, it may not make it into the record.

4. Failing to Bring Documentation

Examiners have limited time and may not pull all your records before the exam. If you have key imaging reports or surgical records, bring them. Many examiners appreciate patients who come organized — and it ensures critical evidence is in front of them during the assessment.

5. Not Requesting a Copy of the C&P Exam Report

You have the right to a copy of your completed DBQ. Request it through the VA after the exam and review it carefully. If it contains errors, contradictions, or is missing key findings you reported, you can address these in a supplemental claim or appeal.

What to Mention — Don't Leave This Out

Specifically bring up the following at your knee C&P exam. These are items that directly influence your rating but are often omitted:

After the Exam: What Happens Next

After the C&P exam, the examiner submits their DBQ report to the VA Regional Office. The rating decision typically follows within 30–90 days. During this time:

  1. Request your C&P exam report: Log into VA.gov or call your regional office to request a copy of the examiner's findings. Review it for accuracy.
  2. Check for errors: Common errors include transposed left/right knee, incorrect ROM measurements, missing documentation of instability or surgical history, or an inadequate examination (examiner who did not perform all tests).
  3. Receive your rating decision: You'll get a letter explaining your rating percentage, effective date, and monthly compensation amount.
  4. Appeal if the rating is wrong: You have one year from the rating decision to file a Supplemental Claim or Higher-Level Review. Don't wait.

If Rated Low: Supplemental Claim Strategy with New Imaging

If your knee was rated at 10% or 0% when you have significant functional impairment, the most effective appeal strategy is a Supplemental Claim (VA Form 20-0995) with new and relevant evidence. Key evidence to add:

📋 Low Knee Rating? Build Your Appeal.

A private orthopedic IMO can document what the C&P exam missed.

REE Medical's physicians review your complete knee history — imaging, surgical records, and functional status — and write IMOs that specifically address DC 5260/5261/5257 criteria. Many veterans see rating increases after adding a private medical opinion.

Veteran Story: The Exam That Changed Everything

Jason M., a 38-year-old Marine infantry veteran, had his right knee C&P exam scheduled two years after discharge following a training accident. He arrived at the exam nervous, in good spirits on an unusually low-pain day, and answered questions minimally — saying his knee "bothers me" and he "can manage" most activities.

The examiner measured his flexion at 105° (because Jason pushed through pain to show his maximum), documented no instability findings (because Jason forgot to mention his weekly "giving way" episodes), and noted the gait as "normal" (because Jason walked carefully for the short distance observed). Result: 10% rating.

Two years later, Jason connected with a VSO who helped him review the C&P report. He filed a Supplemental Claim with: a new MRI showing a posterior horn medial meniscus tear and ACL laxity; a private orthopedist's IMO documenting his actual functional ROM under pain (flexion to 50° with pain onset at 35°), lateral instability on Lachman testing, and weekly giving-way episodes; and a buddy statement from his wife documenting him falling twice from knee giving way.

The VA re-examined Jason and increased his right knee to 20% (DC 5260) plus an additional 10% for instability (DC 5257) — combined 28%, rounded to 30% — worth $537.42/month. Combined with his left knee and back, his total combined rating moved from 30% to 60%.

Frequently Asked Questions

Can I be rated for both knees at the same exam?

Yes. If both knees are claimed (or if your examiner identifies bilateral involvement during the exam), both can be rated. Filing bilateral claims when appropriate is important — and the bilateral factor adds 10% to your combined rating calculation.

What if the C&P examiner doesn't perform stability tests?

If the examiner skips clinical tests you believe are relevant (like Lachman or McMurray), document this in your notes immediately after the exam. An inadequate C&P examination is grounds for a Higher-Level Review requesting a new examination. The VA's duty to assist requires an adequate examination.

Can a knee replacement get a higher rating than 30%?

Yes. A total knee replacement (arthroplasty) may qualify for a 100% temporary rating for 1 year post-surgery under 38 CFR § 4.30. After that, the VA rates residuals — typically under DC 5055 (arthroplasty), which allows ratings of 30%–100% based on functional outcome.

Does the VA consider gait or how I walk?

Yes. Gait observation is part of the DBQ. Limping, antalgic gait (favoring the painful side), or abnormal stride patterns are documented and corroborate functional impairment. Walk naturally — don't try to walk "normally" to appear better than you are.

What if my knee pain is secondary to a back condition?

If your service-connected back condition causes knee pain through altered gait or biomechanical changes, you may be able to claim the knee as secondary to the back under 38 CFR § 3.310. See the nexus letter guide for knee secondary to back injury.
