Knee conditions are among the most claimed VA disabilities — and among the most frequently underrated. Whether you're dealing with a torn meniscus, ACL instability, patellar damage, or simple limitation of motion from years of ruck marching and jumping, the VA has a precise set of tables that translate your exam findings into a disability percentage. This guide decodes those tables, explains the critical painful-motion rule, and shows you exactly how to maximize your knee rating — including the bilateral factor most veterans miss entirely.
The VA rates knee conditions under several diagnostic codes in 38 CFR Part 4, §4.71a. Knowing which code applies to your specific injury — and choosing the most advantageous code — is critical:
| DC | Condition | Key Feature |
|---|---|---|
| 5257 | Recurrent subluxation or lateral instability | Rated on instability severity |
| 5258 | Dislocated semilunar cartilage with locking | 10% minimum; locking episodes matter |
| 5259 | Semilunar cartilage removed, symptomatic | Post-meniscectomy symptoms |
| 5260 | Limitation of flexion of the leg | Flexion table |
| 5261 | Limitation of extension of the leg | Extension table |
| 5262 | Impairment of the tibia and fibula | Structural damage, fractures |
| 5263 | Genu recurvatum | Hyperextension deformity |
The VA is required to rate your knee under whichever code produces the highest rating for your actual condition. If your knee has both limited flexion AND instability, the VA should rate under both — but it cannot combine ratings for the same knee under two codes for the same disability. However, you can receive separate ratings for distinct disabilities of the same knee (e.g., separate codes for instability vs. limitation of extension, if they represent different anatomical issues).
Normal knee flexion is 0° to 140° (full bend). Normal extension is 0° (full straightening). Any limitation of these movements is rated using the VA's standard tables.
| Rating | Flexion Limited To |
|---|---|
| 30% | Flexion limited to 30° or less |
| 20% | Flexion limited to 45° or less (more than 30°) |
| 10% | Flexion limited to 60° or less (more than 45°) |
| 0% (non-compensable) | Flexion limited to more than 60° but less than normal (140°) |
If your C&P exam shows knee flexion to 55°, your rating under DC 5260 is 10%. If your flexion is 42°, your rating is 20%. At 28°, you rate 30%. If range of motion decreases after repetitive use — common in inflamed knees — document that too.
| Rating | Extension Limited To (Degrees from Full Extension) |
|---|---|
| 50% | Extension limited to 45° (cannot straighten past 45° of flexion) |
| 40% | Extension limited to 30° |
| 30% | Extension limited to 20° |
| 20% | Extension limited to 15° |
| 10% | Extension limited to 10° |
| 0% | Extension limited to 5° or less (almost fully straightened) |
Extension limitation means the veteran cannot fully straighten the knee. If your knee is "stuck" at 20° of flexion and you can't extend it further, that's a 20° extension limitation rated at 20%. Extension limitations are often more disabling than equivalent flexion limitations and should always be documented precisely.
Under the DeLuca v. Brown doctrine, the VA must consider range of motion after repetitive use. If your knee's range of motion decreases from 80° to 55° after walking up and down the hallway three times, that post-exercise measurement should be recorded and rated. Always ask your examiner to take measurements after repetitive motion.
This is the most powerful and most overlooked rule in knee ratings. 38 CFR §4.59 states:
"With any form of arthritis, painful motion is an important factor of disability, the facial expression, wincing, etc., on pressure or manipulation, should be carefully noted and definitely related to affected joints. Grating, in a joint, is not as significant. When noted, it should be described descriptively and distinctly from crepitation. The intent of the schedule is to recognize painful motion with joint involvement as productive of disability. It is the intention to rate at least the minimum compensable rating for the joint."
In practice, §4.59 means that if you have a painful knee — even if your range of motion is technically within normal limits — the VA must assign at least the minimum compensable rating for that joint. For knee flexion, the minimum compensable rating under DC 5260 is 10%. For knee extension under DC 5261, the minimum compensable rating is 10%.
Veterans often get rated at 0% despite reporting significant knee pain because the examiner measured normal or near-normal ROM without properly applying §4.59. If you have painful motion and received 0%, consider appealing or filing a Supplemental Claim with a private DBQ documenting the pain on motion.
DC 5257 covers recurrent subluxation (partial dislocation) and lateral instability of the knee — typically caused by ACL, PCL, MCL, or LCL tears or laxity. This is a standalone code that rates the instability itself, separate from any limitation of motion.
| Rating | Instability Severity |
|---|---|
| 30% | Severe instability |
| 20% | Moderate instability |
| 10% | Slight instability |
The terms "slight," "moderate," and "severe" are not precisely defined in the regulation, leaving room for examiner interpretation. As a general guide:
Critically, the VA can rate DC 5257 (instability) separately from DC 5260 (limitation of flexion) for the same knee — as long as they represent genuinely separate disabilities or limitations. However, pyramiding rules prohibit double-rating the same manifestation of disability. If your limitation of motion is caused by instability alone (you don't bend the knee because it gives way), the VA may only apply one code. If you have both structural instability AND independent limitation of motion from a different cause (cartilage damage, post-surgical changes), both may be rated separately.
Use the claim.vet disability calculator to see how your knee rating combines with other conditions to reach your total combined rating.
Calculate My Combined Rating →This code applies to a meniscus that intermittently displaces, causing the knee to "lock" (become momentarily unable to extend) along with painful motion or effusion (fluid accumulation). The rating for DC 5258 is a flat 20% for this condition.
To support this rating, document:
If you've had a meniscectomy (partial or total meniscus removal) and continue to have symptoms, DC 5259 applies. The rating is a flat 10%.
Veterans sometimes believe that having knee surgery means their condition is "fixed" and no longer ratable. This is wrong. Post-surgical symptoms — pain, swelling, instability, limitation of motion — are all ratable. If you're still symptomatic after surgery, document every symptom carefully and consider whether DC 5260 (limitation of flexion) might provide a higher rating than DC 5259's flat 10%.
This code applies when structural damage to the tibia or fibula causes knee impairment — for example, following tibial plateau fractures or fractures affecting the joint. Ratings range from 10% to 40% depending on the degree of malunion, deformity, or loss of motion resulting from the bony injury.
Genu recurvatum is hyperextension deformity of the knee — the knee bends backward past 0°. This is rated at a flat 10% under DC 5263. If associated limitation of motion is present, that may be rated additionally under the appropriate motion code.
Patellar subluxation or dislocation (kneecap instability) is typically rated under DC 5257 as lateral instability. Document frequency of subluxation events, whether they require manual reduction, and any functional limitations.
If your knee has documented arthritis (osteoarthritis, post-traumatic arthritis) confirmed by X-ray, the VA can rate it under DC 5003 (Degenerative Arthritis) — sometimes called "arthritis with limitation of motion." This code provides an alternative pathway when ROM limitations meet the arthritis criteria.
Under DC 5003:
However, DC 5003 also states that if the limitation of motion for the specific joint warrants a higher rating, the higher rating applies. In practice, this means arthritis under DC 5003 provides a floor — if your ROM limitation under DC 5260 or 5261 rates higher, use those codes instead.
Service-connected knee injuries (ACL tears, meniscus damage, fractures) often lead to progressive traumatic arthritis years or decades later. If your original knee rating was established for an injury and arthritis has since developed, file for an increased rating based on the arthritis — it's still service-connected through its nexus to the original injury.
One of the most commonly missed benefits in knee claims is the bilateral factor under 38 CFR §4.68. If you have service-connected disabilities affecting both legs — including bilateral knee conditions — the combined rating for those bilateral conditions is increased by 10% before combining with other disabilities.
Example: You have a 20% rating for your right knee and a 20% rating for your left knee. Combined, they would equal 36% under the VA's combined rating formula (100 − [(100−20) × (100−20)/100] = 36%). The bilateral factor adds 10% of 36% = 3.6%, rounding to approximately 40% before combining with other disabilities.
The bilateral factor applies whenever both limbs are involved — both knees, both ankles, both hips, or any combination of paired lower extremity disabilities affecting gait. It must be calculated before combining bilateral conditions with other unrelated disabilities.
If you have bilateral knee conditions, make sure each knee is rated separately and the bilateral factor is applied. Many veterans receive ratings for only one knee or have the bilateral factor omitted from their combined calculation. This is an error you can challenge in an appeal or Supplemental Claim.
Knee injuries rarely stay isolated. Altered gait, compensatory movement patterns, and referred pain commonly cause secondary conditions in adjacent joints and structures. File secondary claims for any of the following:
Limping or altered gait from a knee injury forces the hip into abnormal loading patterns, causing hip bursitis, hip flexor strain, IT band syndrome, or hip arthritis. These can be rated separately as secondary to your knee condition. The nexus is straightforward: your treating physician can document that hip pain developed as a result of gait changes caused by your service-connected knee condition.
Similarly, altered gait from knee instability or limited motion can cause secondary ankle instability, plantar fasciitis, or Achilles tendinopathy. Document any foot/ankle symptoms you developed after your knee injury and file secondary claims with a supporting nexus letter.
In some cases, knee injuries from service involve the peroneal nerve — which crosses the lateral knee and can be damaged in lateral knee trauma or surgery. Peroneal nerve injury (DC 8521) can cause foot drop, weakness, and numbness in the lower leg and foot. If you have these symptoms, they may be ratable as secondary to your service-connected knee condition at 10%–80% depending on severity.
Chronic knee pain is a recognized risk factor for depression and anxiety. If you're receiving mental health treatment for depression, anxiety, or PTSD related to your chronic knee pain and functional limitations, file a secondary mental health claim supported by your treating provider's documentation.
Veterans with severe bilateral knee limitation, significant instability, or combined ratings approaching 70% should also evaluate eligibility for Total Disability Individual Unemployability (TDIU) — which pays at the 100% rate if you can demonstrate that your service-connected disabilities prevent substantially gainful employment. Use the rating estimator to see if your combined knee and secondary ratings approach TDIU territory.
The following are 2025 monthly VA disability compensation rates (effective December 1, 2024, with 2.5% COLA) for a veteran with no dependents:
| Combined Rating | Monthly Pay (No Dependents) |
|---|---|
| 10% | $175.51 |
| 20% | $346.95 |
| 30% | $537.42 |
| 40% | $774.16 |
| 50% | $1,102.04 |
| 60% | $1,395.93 |
| 70% | $1,759.19 |
| 80% | $2,044.89 |
| 90% | $2,297.96 |
| 100% | $3,831.30 |
Consider a veteran with bilateral knee conditions: 20% right knee (DC 5260, flexion limited to 45°) + 20% left knee (DC 5260, same) + 10% bilateral factor adjustment. Combined knee rating ≈ 40%. Add 20% for moderate right knee instability under DC 5257 (rated separately from limitation of motion if distinct disability). Total combined: approximately 50%, or $1,102.04/month in 2025. With secondary hip bursitis at 10%, the combined climbs to approximately 55%, rounded to 60% = $1,395.93/month.
Accurate documentation and knowing which codes apply makes a real difference in what you receive each month for the rest of your life.
