Knee pain is a widespread issue among veterans due to the physically demanding nature of military service. From intense training to combat-related injuries, these experiences can lead to long-term knee conditions. However, navigating the VA disability claims process for knee pain can be complex and overwhelming. This blog offers an overview of key factors that can support your knee disability claim and improve your chances in some instances of receiving the VA compensation you deserve.
Understanding Knee Pain in Veterans
Over 75% of military-related musculoskeletal injuries involve the lower limb, with the knee being the most commonly affected area. In fact, US Army Soldiers are over 5 times as likely to be diagnosed with incident knee post-traumatic osteoarthritis (PTOA) when compared to those in the general population. Veterans largely suffer knee pain due to service-related injuries such as fractures, dislocations, sprains, or repetitive strain can lead to various knee problems over time. Conditions like arthritis, tendinitis, and bursitis can also contribute to knee pain, causing swelling, stiffness, instability, and reduced mobility.
Veterans may experience knee pain symptoms like sharp pain, swelling, stiffness, redness, weakness, instability, popping sounds, and a crunching sensation in the knee. Diagnosing and treating knee pain early is essential for managing symptoms effectively and preventing further damage.
Paratroopers are at a higher risk for knee injuries as airborne operations often impact the lower limbs. The MIRROR program collaborated with United States Army paratroopers and found that over 50% sustain injuries annually, with 37% of paratrooper injuries affecting the knee and 26% the ankle.
Common Knee Conditions Eligible for VA Disability Benefits
The Department of Veterans Affairs (VA) offers disability compensation for various knee conditions connected to military service. Understanding which knee problems qualify for VA disability benefits is crucial for veterans seeking compensation.
Several knee conditions may qualify veterans for VA disability compensation, including but not limited to:
- Osteoarthritis: A CDC report found that arthritis is 60% more prevalent than among nonveterans. The most common form of arthritis where cartilage breakdown leads to joint pain, stiffness, and swelling.
- Instability of the Knee: A sensation of the knee giving way or moving side-to-side during basic activities.
- Subluxation: Partial dislocation causing knee pain, swelling, and limited mobility.
- Ankylosis: Stiffness in the knee that limits or prevents movement, often resulting from injury or disease.
- Effusion (Water on the Knee): Excess fluid buildup causing swelling and discomfort.
- Hyperextension: Overextension of the knee joint beyond its normal range, often leading to damage.
- Bursitis: Inflammation of the bursae, small fluid-filled sacs that cushion joints, causing pain and swelling.
- Tendon or Ligament Tears: Damage to knee ligaments like the ACL, PCL, or meniscus injuries, resulting in instability and pain.
- Rheumatoid Arthritis: An autoimmune disorder that causes chronic joint inflammation, including in the knees.
- Osteomyelitis: A bone infection that may cause chronic pain and swelling in the knee.
To qualify for compensation, veterans must establish a service connection, proving that their knee condition was caused or worsened by military service. This often involves medical documentation, service records, and often completing a Compensation and Pension (C&P) exam. The VA uses a Disability Benefits Questionnaire (DBQ) to assess the severity of knee and leg impairments and assign a disability rating.
Service Connection for Knee Conditions
Establishing a service connection for knee disabilities involves proving how military service contributed to the condition. This can be done through direct service connection, secondary service connection, either of which can be demonstrated by either causation or aggravation of a pre-existing condition. Each path requires specific evidence and has unique criteria for approval.
Direct Service Connection for Knee Pain
A direct service connection is established when a veteran can directly link their knee condition on a causal or aggravational basis to an incident or injury that occurred during their military service. To win a VA knee claim, veterans submit three key components to prove a direct connection: a current medical diagnosis, evidence of an in-service event or injury, and a medical nexus linking the two.
Secondary Service Connection for Knee Pain
A secondary service connection claim applies when an already service-connected primary condition causes the veteran to injure or overuse another condition or joint, often by things like adjusting their movement or posture, leading to a secondary condition. For example, a veteran with a back injury develops knee arthritis from altered walking patterns, making it a secondary service connection.
These are the common secondary conditions related to knee pain:
- Hip and Back Pain: Changes in gait to avoid knee pain can strain the hips and lower back.
- Ankle and Foot Problems: Altered walking patterns may lead to injuries in the ankle and foot.
- Degenerative Arthritis: Overuse of other joints due to knee instability can accelerate arthritis.
- Muscle Weakness: Reduced mobility may weaken surrounding muscles, leading to further instability.
- Nerve Damage: Severe knee injuries can affect nearby nerves, causing pain or numbness.
- Mental Health Conditions: Chronic knee pain can contribute to depression and anxiety due to decreased mobility and quality of life.
Proper medical documentation, service treatment records, and a nexus opinion clearly establishing how the primary knee condition caused or aggravated the secondary disability is vital for securing additional compensation. Recognizing and claiming secondary conditions can increase a veteran’s overall disability rating for knee pain, leading to higher monthly benefits in many cases.
Aggravated Service Connection for Knee Pain
Aggravation applies when a pre-existing knee condition is worsened beyond its natural progression due to military service. For example, a veteran with pre-existing mild knee pain regularly carried heavy equipment and participated in physically demanding tasks. After military service, the veteran now experiences severe knee instability and requires replacement surgery. Providing medical evidence of how the veteran’s military deployment deteriorated the knee condition beyond normal aging may strengthen this particular example VA claim for aggravation.
VA Knee Rating Chart Explained
Disability ratings reflect how significantly a knee condition impairs a veteran’s ability to work and perform daily activities. Knee disability ratings range from 0% to 100% and are assigned based on the severity of symptoms, the degree of movement limitation, pain, instability, and the need for assistive devices.
Under 38 CFR § 4.71a (Schedule of ratings—musculoskeletal system), the Department of Veterans Affairs (VA) evaluates knee disabilities through specific diagnostic codes.
1. Limitation of Flexion of the Knee — Diagnostic Code 5260
This is the most common service-connected knee condition, referring to restricted bending of the knee inward toward the body. The VA rates the limitation of knee flexion strictly based on the range of motion rather than how much pain it causes.
- 30% – Flexion limited to 15°
- 20% – Flexion limited to 30°
- 10% – Flexion limited to 45°
- 0% – Flexion limited to 60°
2. Limitation of Extension of the Knee — Diagnostic Code 5261
This condition involves the inability to fully straighten the knee, which makes standing and walking painful and difficult. Higher VA ratings are given for more severe limitations in extension.
- 50% – Extension limited to 45°
- 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°
3. Instability of the Knee — Diagnostic Code 5257
Instability refers to excessive movement of the knee joint, often due to damaged ligaments, resulting in the knee giving out or dislocating. VA disability ratings for knee instability depend on the severity:
- 30% – Severe instability requiring both bracing and assistive devices (cane, crutch, or walker)
- 20% – Moderate instability with prescribed bracing or assistive devices
- 10% – Mild instability without the need for assistive devices
This diagnostic code also covers patellar instability, where the kneecap becomes displaced.
4. Ankylosis of the Knee — Diagnostic Code 5256
Ankylosis refers to abnormal stiffening and immobility due to bone fusion, which severely limits knee function and often veterans require assistive devices. The degree of immobility affects the ankylosis of the knee VA rating:
- 60% – Flexion at 45° or more (extremely unfavorable)
- 50% – Flexion between 20° and 45°
- 40% – Flexion between 10° and 20°
- 30% – Full extension or slight flexion between 0° and 10°
5. Total Knee Replacements — Diagnostic Code 5055
Veterans who have undergone a total knee replacement surgery with prosthetics are awarded a temporary rating of 100% disability for the first four months post-surgery to allow for recovery. After this period, a Compensation & Pension (C&P) exam is conducted to determine the veteran’s long-term VA disability rating based on their recovery and ongoing symptoms.
- 60% – Chronic severe pain or weakness
- 30% – Intermediate symptoms like moderate pain and limited motion
- Minimum rating: 30%, even if motion has improved
6. Partial Knee Replacements
Partial knee replacements do not have a dedicated diagnostic code. They are rated based on resulting symptoms, such as pain, limited motion, or instability, often under Diagnostic Codes 5260, 5261, or 5257.
Additional Knee Conditions and Ratings
- Meniscus injuries (Diagnostic Codes 5258 & 5259) are rated at 20% for frequent locking, pain, and fluid buildup, and 10% for symptomatic removal of cartilage.
- Tibia and fibula impairments (Diagnostic Code 5262) are rated at 40% for nonunion with loose motion requiring a brace, 30% for malunion with marked knee or ankle disability, and 10–20% for moderate to slight disabilities.
- Genu recurvatum (Diagnostic Code 5263) receives a 10% rating for knee hyperextension causing weakness and instability.
Pain and Functional Loss Considerations
While many knee conditions are rated strictly on the range of motion, the VA also considers functional loss due to pain. Pain that limits function can justify a higher rating, even if the measured range of motion falls into a lower category. The VA rates knee pain based on the following factors:
- Chronic pain impacting daily activities
- Swelling and instability
- Use of braces or assistive devices (canes, crutches, walkers)
Knee Arthritis and the Major Joint Rule
The VA’s Major Joint Rule guides disability ratings for veterans with knee arthritis. Initially, the VA assesses the knee’s range of motion using Diagnostic Codes 5260 (limitation of flexion) and 5261 (limitation of extension). If the range of motion appears normal but pain persists, the VA applies Diagnostic Code 5003 for arthritis.
When arthritis is confirmed by X-ray, the VA assigns a 10% or 20% disability rating based on severity of the joint pain and whether one or both knees are affected. This approach ensures veterans receive the maximum benefits for their knee arthritis.
Separate VA Disability Ratings for Multiple Knee Conditions
The VA can assign separate disability ratings for different knee impairments if they affect distinct functions. For example, a veteran may receive separate ratings for limited flexion (bending) and limited extension (straightening) of the knee. However, the VA prohibits “pyramiding,” or rating the same symptom twice. Proper documentation of separate knee limitations may help veterans ensure fair compensation.
Total Disability Based on Individual Unemployability (TDIU)
Veterans unable to work due to severe knee problems may qualify for TDIU, providing compensation at the 100% disability rate, even without a 100% combined rating. To be eligible, veterans must show how their knee disability prevents gainful employment. Qualification requires either:
- One disability rated at 60% or more
- Multiple disabilities combining to 70% VA rating with at least one at 40%
Bilateral Factor
If both knees are service-connected, the VA applies the bilateral factor, increasing the combined disability rating. This acknowledges how disabilities in both limbs more severely impact mobility and daily function.
Veterans with service-connected knee conditions, whether it’s pain, limited motion, instability, or post-surgical complications, are entitled to fair VA compensation that supports their lives.
Proving Service Connection for Knee Pain
Proving service connection for knee pain is essential for veterans seeking VA disability compensation. To secure a VA rating for knee pain, a veteran must establish a service connection by satisfying three key criteria:
1. Current Medical Diagnosis
The foundation of any successful VA disability claim is a current medical diagnosis provided by a qualified medical professional. Diagnoses like osteoarthritis, meniscus tears, or ligament damage must directly explain the pain experienced. Ensure that the medical records detail the specific knee injury rather than attributing pain to general discomfort or aging.
2. In-Service Event or Injury Documentation
Veterans must provide evidence of an in-service event, injury, or exposure that caused or aggravated their knee disability. This documentation can include service treatment records (STRs), incident reports, deployment records, or personal medical logs detailing symptoms kept during service. Consistent and detailed documentation of the service-connected disability may greatly strengthen the VA claim.
3. Medical Nexus
The medical nexus is a critical component in linking a veteran’s knee injury or condition to their military service. It is important to note that a nexus can be provided at the VA C&P exam. A medical nexus letter is a narrative document that outlines the nexus and is not a requirement but may bolster a veteran’s evidence in some cases. A qualified medical provider, in this case, a primary care physician, orthopaedic surgeon, or an independent medical examiner (IME) can write a nexus letter for knee conditions. They review the veteran’s medical history and offer an expert opinion on whether the knee condition is “at least as likely as not” connected to service.
Lay statements from veterans, family, or service members describing the onset, frequency, and daily impact of knee pain can also strengthen compensation claims, especially when there is a lack of medical evidence.
Building a Strong VA Claim with a Medical Nexus Letter for Knee Pain
A nexus letter presents a clear medical opinion linking a veteran’s current knee condition directly to their military service. This professional document can significantly impact the outcome of a VA disability claim in some cases. An effective nexus opinion letter is supported by detailed medical reasoning that refers to service treatment records, diagnostic imaging (X-rays, MRIs), and relevant medical literature. The letter should also highlight the credentials and expertise of the physician to establish credibility.
Prestige Veteran specializes in creating comprehensive, evidence-based nexus letters. Our skilled medical professionals thoroughly review service records and medical histories to craft well-supported nexus opinions that strengthen claims.
To build a strong VA disability claim for knee pain, veterans should consult with accredited legal professionals who will advise on the following when applicable:
- Gather medical records documenting diagnoses, treatments, and persistent symptoms.
- Provide service records or incident reports detailing the in-service event causing or worsening the knee condition.
- Obtain a professionally written nexus letter that connects the knee pain to military service if needed.
Veterans and their accredited legal representatives will gather evidence to file a VA disability claim for knee pain, often by submitting VA Form 21-526EZ with comprehensive medical records, service documents, and a detailed nexus letter to maximize your chances of receiving fair VA disability benefits.
Compensation & Pension (C&P) Exam for Knee Pain
The VA Compensation & Pension (C&P) exam is conducted by a VA or VA-contracted examiner who assesses the severity and functional impact of a veteran’s knee pain for disability compensation. The C&P examiner reviews medical records, asks about symptoms like pain and instability, and performs physical tests, including the range of motion assessments using a goniometer.
Veterans should keep a record of symptom flare-ups, pain levels, and mobility issues to provide the most detailed history at the C&P exam. Veterans should openly discuss the severity of the knee injury as downplaying symptoms can lead to a lower disability rating.
Disability Benefits Questionnaire (DBQ) for Knee Conditions
When attending the C&P exam, the examiner will complete a Disability Benefits Questionnaire (DBQ) specific to knee and lower leg conditions. The DBQ gathers detailed information about the injury, symptoms, treatment history, and daily impact. Providing thorough and honest information on the DBQ allows the examiner to better understand the extent of the veteran’s knee impairment.
Consulting a VA-accredited representative, such as a Veterans Service Officer (VSO), claims agent, or VA-accredited attorney, ensures proper guidance in filing disability claims and navigating complex VA processes to maximize benefits.
Conclusion
Securing VA disability compensation for knee pain is more than just filing a claim—it’s about presenting a compelling case that reflects the true impact of your service-related injury. By understanding how to connect your knee condition to military service, providing strong medical evidence, and leveraging expert support from accredited legal professionals you can take control of the process. With persistence and the right strategy, you can secure the compensation you deserve and move forward with much-needed peace of mind.
