A knee disability can involve different manifestations, including limited flexion, limited extension, and instability. VA may evaluate distinct manifestations separately when the rules permit and the same impairment is not counted twice. Any resulting evaluations are combined under VA math rather than added as ordinary percentages.
This article explains the diagnostic codes, range-of-motion measurement rules, the § 4.59 painful-motion provision, common knee conditions, and records that may help document the symptoms and functional limits VA evaluates.
Distinct findings require a distinct analysis
Flexion, extension, and instability are different measurements or manifestations. Separate evaluations are possible only when the evidence satisfies the applicable criteria and the same impairment is not compensated twice under § 4.14. A decision letter that addresses one code does not by itself establish entitlement under another.
How the current knee codes differ
DC 5260 — Limitation of flexion (how far you can bend it)
Normal flexion is 0–140°. The schedule:
- Flexion limited to 45° → 10%
- Flexion limited to 30° → 20%
- Flexion limited to 15° → 30% (maximum for flexion alone)
DC 5261 — Limitation of extension (how far you can straighten it)
Normal extension is 0°. The schedule:
- Extension limited to 10° → 10%
- Extension limited to 15° → 20%
- Extension limited to 20° → 30%
- Extension limited to 30° → 40%
- Extension limited to 45° → 50%
DC 5257 — Recurrent subluxation or instability
Current DC 5257 no longer uses the former slight, moderate, and severe labels.
Recurrent subluxation or ligament instability:
- 10%: a sprain, incomplete ligament tear, or complete ligament tear (repaired, unrepaired, or failed repair) causes persistent instability, without a medical-provider prescription for a brace or assistive device for ambulation.
- 20%: either (a) a sprain, incomplete ligament tear, or repaired complete ligament tear causes persistent instability and a medical provider prescribes a brace and/or assistive device, or (b) an unrepaired or failed repair of a complete ligament tear causes persistent instability and a provider prescribes either bracing or an assistive device.
- 30%: an unrepaired or failed repair of a complete ligament tear causes persistent instability and a provider prescribes both bracing and an assistive device for ambulation.
Patellar instability:
- 10%: a diagnosed patellofemoral-complex condition causes recurrent instability, with or without a history of surgical repair, and does not require a provider prescription for a brace, cane, or walker.
- 20%: the diagnosed condition causes recurrent instability after surgical repair and requires a provider prescription for a brace, cane, or walker.
- 30%: the diagnosed condition causes recurrent instability after surgical repair and requires a provider prescription for a brace and either a cane or walker.
The regulation also defines the patellofemoral complex and limits what qualifies as surgical repair. Read both notes to DC 5257 in the current schedule before applying these levels.
Meniscus codes — DC 5258 and 5259
- DC 5258 — dislocated semilunar cartilage with frequent episodes of locking, pain, and effusion into the joint → flat 20%.
- DC 5259 — symptomatic removal of semilunar cartilage (after a meniscectomy) → flat 10%.
Separate evaluations depend on whether the manifestations are distinct and are not compensated twice. DC 5258 specifically requires frequent episodes of locking, pain, and effusion into the joint.
The measurement rules the VA gets wrong
Knee ratings are driven by numbers, and the numbers have to be collected correctly:
The goniometer + Correia rule
Range of motion must be measured with a goniometer, and under Correia v. McDonald (2016) the exam must record active and passive motion, weight-bearing and non-weight-bearing, and compare to the opposite (undamaged) knee. If relevant measurements are absent, review the full report and ask an accredited representative whether clarification or a new examination may be appropriate in the specific case.
The § 4.59 painful-motion floor
38 CFR § 4.59 entitles a painful joint to at least the minimum compensable rating — 10% for the knee — even if motion is otherwise full. Burton v. Shinseki (2011) and Petitti v. McDonald (2017) discuss its application. The outcome remains dependent on the evidence and the diagnostic code used.
The DeLuca / Mitchell flare-up rule
Under DeLuca v. Brown (1995) and Mitchell v. Shinseki (2011), the examiner must account for additional loss of motion during flare-ups and after repetitive use — not just your range on a good day in a quiet exam room. Describe how often flare-ups occur, how long they last, what causes them, and the additional functional loss you actually experience.
Common knee conditions and what they support
- Osteoarthritis / degenerative joint disease — the most common. X-ray- confirmed arthritis with painful, limited motion drives 5260/5261 plus the § 4.59 floor.
- Meniscus tear — MRI-confirmed; locking and effusion support DC 5258, and post-surgical residuals support DC 5259.
- ACL / ligament injury — the classic basis for instability under DC 5257; a brace and giving-way episodes are the key facts.
For the full schedule, the medical background, and the rater mistakes to watch for, the knee condition guide carries every diagnostic code in detail, including post-surgical (DC 5055) ratings.
Records that may help document a knee condition
- Get imaging on file. An X-ray confirming arthritis or an MRI confirming a meniscal/ligament injury is the diagnostic anchor.
- Establish the in-service link. Service treatment records for the original injury, or a buddy statement describing it and the continuity of symptoms since. The buddy statement guide has the template.
- Document instability accurately. Note giving-way episodes, medical findings, surgical history, and whether a medical provider prescribed bracing or an assistive device.
- Prepare for the C&P exam. Read the Knee DBQ field guide to understand the measurements and history the examiner may address, then use the C&P Exam Prep tool for your specific codes.
- Read the decision letter. It should identify the code used and explain the evidence and criteria considered. A VA-accredited representative can help assess whether a review option is appropriate.
Give an accurate picture of flare-ups and repeated use
“I just take ibuprofen and push through” and “it only gives out occasionally” can leave the examiner without enough detail. Be specific about the typical frequency, duration, triggers, functional loss, and assistive-device use. Do not minimize or portray an exceptional episode as the everyday baseline. The Knee DBQ guide explains the measurements and topics the examiner may address.
If both knees are involved: the bilateral factor
When compensable disabilities affect both paired lower extremities and the requirements of 38 CFR § 4.26 are met, VA applies the bilateral factor before combining that result with other disability evaluations. The Claim Coach and the math calculator both account for it.
Quick answers
Can I get two VA ratings for the same knee?
Separate evaluations may be possible when the medical findings establish distinct manifestations that are not compensated twice. Limitation of flexion, limitation of extension, and qualifying instability are evaluated under different diagnostic codes, but the result is fact-specific and subject to VA’s rule against pyramiding in 38 CFR § 4.14.
How does the VA measure knee range of motion?
VA regulations identify the goniometer as indispensable for accurate joint measurements. Joint examinations should address active and passive motion and weight-bearing and non-weight-bearing testing when applicable. Whether an omitted measurement makes a particular examination inadequate depends on the full report, the affected joint, and whether the missing information can be obtained or explained.
What are the knee diagnostic codes and their ratings?
DC 5260 addresses limitation of flexion, DC 5261 addresses limitation of extension, and DC 5257 addresses recurrent subluxation or instability and patellar instability under detailed ligament, surgical-repair, and prescribed-device criteria. DC 5258 addresses dislocated semilunar cartilage with frequent locking, pain, and effusion, and DC 5259 addresses symptomatic removal of semilunar cartilage. Check the current text of 38 CFR § 4.71a for every level and note.
What is the § 4.59 painful motion rule?
38 CFR § 4.59 states an intent to recognize actually painful, unstable, or malaligned joints due to healed injury as entitled to at least the minimum compensable rating for the joint. Applying that provision is fact-specific and depends on the competent evidence and the diagnostic code used.
When can the bilateral factor apply to knee disabilities?
When compensable disabilities affect both paired lower extremities and the requirements of 38 CFR § 4.26 are met, VA applies the bilateral factor before combining those evaluations with other disabilities. Whether it applies depends on the ratings in the individual record.
What evidence may help document a knee condition?
A current diagnosis, relevant service or treatment records, lay statements describing observable symptoms or events, imaging when clinically appropriate, and an examination that documents range of motion, pain, instability, and functional loss during flare-ups may help describe the record. What is relevant depends on the condition and the applicable diagnostic criteria.
