What Is the VA Rating for an ACL Tear?

You tore your ACL during service, had surgery, and still deal with a knee that buckles without warning. But the VA gave you 10%.

Sound familiar?

ACL tears are one of the most common service-connected knee injuries, yet veterans consistently receive lower ratings than their condition warrants. The problem is that VA does not rate the ACL tear itself. It rates the resulting instability under a diagnostic code most veterans have never heard of.

In this guide, I'll break down exactly how the VA rates ACL tears, how to get a temporary 100% rating for ACL reconstruction surgery, and the little-known strategies that can significantly increase your compensation.

Specifically, you'll learn:

• How DC 5257 works and what instability level gets you 10%, 20%, or 30%
• How to claim a temporary 100% rating for ACL reconstruction under 38 CFR 4.30
• Why you may qualify for separate ratings for meniscus damage on top of your ACL rating
• The amputation rule cap and a critical interpretation that could work in your favor
• How surgical convalescence can unlock SMC-S eligibility

How VA Rates ACL Tears Under DC 5257

The VA does not have a diagnostic code specifically for ACL tears. Instead, it rates the functional impairment that results from the tear: recurrent subluxation or lateral instability.

This falls under Diagnostic Code 5257 ("Knee, other impairment of").

Here's why this matters:

DC 5257 is not based on range of motion. It is based entirely on how unstable your knee is. That means the examiner must test for instability, not just measure how far your knee bends.

The Subjective Nature of "Slight" vs. "Moderate" vs. "Severe"

One of the biggest problems with DC 5257 is that the terms "slight," "moderate," and "severe" are not defined with objective measurements. There is no goniometer reading or millimeter threshold that separates one level from the next.

This is both a challenge and an opportunity.

It means the examiner's clinical judgment carries enormous weight. But it also means you can submit lay evidence describing how instability affects your daily life. Under Jandreau v. Nicholson, 492 F.3d 1372 (Fed. Cir. 2007), your testimony about observable symptoms like your knee buckling is competent evidence.

Temporary 100% Rating for ACL Surgery

This is one of the most underused benefits for veterans with ACL injuries.

Under 38 CFR 4.30, if you undergo ACL reconstruction surgery, you can receive a temporary 100% convalescence rating during your recovery period.

And the BVA has confirmed it:

Board of Veterans' Appeals decisions establish that ACL reconstruction qualifies as a "major surgical procedure" under 38 CFR 4.30. This means you are entitled to a temporary total rating for the period of recovery.

How Long Does the Temporary 100% Last?

The standard convalescence period is one to three months, but it can be extended based on:

• Surgical complications or infections
• Extended immobilization requirements
• Need for additional surgery (graft failure, revision)
• Documented inability to return to pre-surgical activity level

Separate Meniscus Ratings (DC 5258/5259)

ACL tears frequently occur alongside meniscus injuries. When they do, you may be entitled to separate ratings for each condition under different diagnostic codes.

This is not pyramiding. These are distinct disabilities evaluated on different criteria.

This means a veteran with an ACL tear and a meniscus injury could receive:

• 10-30% under DC 5257 for knee instability from the ACL tear
• 10-20% under DC 5258 or 5259 for the meniscus condition
• Additional ratings for limited range of motion under DC 5260/5261 if arthritis develops

The Amputation Rule Cap (38 CFR 4.68)

There is an important ceiling that applies when you have multiple knee and leg disabilities.

Under 38 CFR 4.68, combined ratings for disabilities below the knee cannot exceed the 40% rating that would be assigned for a below-knee amputation (DC 5165).

So if you have:

• 30% for ACL instability (DC 5257)
• 20% for meniscus (DC 5258)
• 10% for arthritis/ROM limitation (DC 5261)

Using VA math, those combine to about 49%. But the amputation rule would cap it at 40%.

But here's where it gets interesting:

The "Below the Knee" Interpretation

The regulatory text of 38 CFR 4.68 uses the phrase "below the knee." Anatomically, "below the knee" refers to the lower leg — the tibia, fibula, ankle, and foot — not the knee joint itself.

This raises a critical question: does the 40% cap apply to knee joint disabilities (ACL, meniscus, patella) or only to disabilities of the lower leg?

SMC-S Eligibility During Convalescence

This is the connection that almost nobody makes.

When you receive a temporary 100% convalescence rating under 38 CFR 4.30 for ACL reconstruction, you may also qualify for Special Monthly Compensation at the S rate (SMC-S).

Under O.G.C. Precedent 02-94, temporary 100% ratings qualify for SMC-S if you meet one of these conditions:

• You have a separate service-connected disability rated at 100%, OR
• Your combined rating reaches 100% with an additional 60% from independent disabilities

SMC-S provides an additional monthly payment on top of the 100% rate. For veterans with high combined ratings who undergo ACL surgery, this creates a time-limited eligibility window that most never claim.

What to Expect at Your C&P Exam

Your C&P examination for an ACL tear should include specific instability testing. If it doesn't, the exam may be inadequate.

Tests the Examiner Should Perform

• Anterior drawer test — pulling the tibia forward to check ACL integrity
• Lachman test — the most sensitive clinical test for ACL tears
• Pivot shift test — rotational instability assessment
• Range of motion — both active and passive, with repetitive use testing
• Functional assessment — impact on walking, stairs, standing, daily activities

The examiner should also document:

• Whether you use a knee brace and how often
• History of falls or episodes of the knee giving way
• Impact on occupational activities
• Any meniscus findings (locking, effusion, pain)

Your Next Steps

If you have a service-connected ACL tear and believe your rating is too low, here is your action plan:

1. Review your C&P exam — Did the examiner perform instability testing (anterior drawer, Lachman, pivot shift)? If not, request a new exam under Barr v. Nicholson
2. Check for missing meniscus rating — If you have documented meniscus damage, ensure you have a separate rating under DC 5258 or DC 5259
3. File for convalescence if you had surgery — Temporary 100% under 38 CFR 4.30 applies to ACL reconstruction, even retroactively
4. Evaluate SMC-S eligibility — If you have a high combined rating, your convalescence period may trigger additional compensation
5. Document instability daily — A symptom journal with dates, activities, and episodes of giving way strengthens your case for moderate or severe instability

Remember, under Gilbert v. Derwinski, 1 Vet. App. 49 (1990), when the evidence is roughly equal for and against your claim, the benefit of the doubt goes to you.

Now I'd like to hear from you — have you been rated for ACL instability, or are you still trying to figure out where to start?
