Average DVA Payout for Knee Osteoarthritis (2026)

Most veterans with service-related knee osteoarthritis receive between $37,000 and $171,000 in permanent impairment compensation under the MRCA, depending on severity, whether one or both knees are affected, and whether you take a lump sum or fortnightly payments. Unilateral knee OA with moderate functional loss typically scores 10 to 15 impairment points. Bilateral cases, post-surgical knees, and severe degeneration with walking aids can push to 25 to 30 points or higher when combined.

Knee OA is one of the most commonly claimed musculoskeletal conditions across the ADF. Infantry, armoured corps, combat engineers, and anyone who spent years running, marching, carrying loads, and kneeling on hard surfaces are at elevated risk. The SoP factors align closely with standard military physical demands.

How DVA calculates your knee OA payout

GARP M assessment (Chapter 3, Table 3.2.2)

Knee osteoarthritis is assessed under GARP M Chapter 3, Part 3.2 (Lower Limbs) using Table 3.2.2 (Lower Limb Functional Loss). The assessor measures range of motion (flexion and extension) against normal benchmarks, walking capacity and gait pattern, need for walking aids, stair climbing ability, and pain effects on function.

If both knees are affected by OA from distinct causes or at different times, each knee is assessed separately and the ratings are combined using the proportional method.

Table 3.4.1 adds a separate resting joint pain assessment. If your knees hurt at rest (not just during movement or load-bearing), this should be documented and rated. It is commonly missed.

Age adjustment applies under Table 3.6.1. Veterans aged 45 and under receive an increased rating. Veterans aged 56 and over receive a reduced rating.

Typical impairment point ranges

What your payout looks like in dollars

These ranges assume warlike or non-warlike service. Peacetime rates are approximately 40 to 55% lower.

Unilateral knee OA

Bilateral knee OA

What affects your payout

Unilateral vs bilateral

Two affected knees mean more impairment points and more compensation. Each knee should be assessed, and the ratings combined. If both knees developed OA from military service, claim both.

Severity of functional loss

The rating is driven by what you can and can’t do, not just what the imaging shows. Severe cartilage loss on MRI with full functional capacity scores lower than moderate cartilage loss with significant walking difficulty. Document your functional limitations honestly.

Post-surgical status

Total knee replacement significantly alters the assessment. Your rating is based on post-surgical residual function. Some veterans function well after replacement (lower points). Others have persistent stiffness, pain, or complications (higher points). Post-surgical complications may justify a separate claim.

Secondary conditions

Knee OA commonly causes altered gait, which leads to hip OA, lumbar spondylosis, or contralateral knee problems. Chronic knee pain can also contribute to depression. Each secondary condition can be claimed separately.

Age adjustment

Younger veterans receive higher adjusted ratings under Table 3.6.1, and larger lump sums due to the actuarial conversion factor. A 30-year-old with moderate bilateral knee OA receives substantially more than a 55-year-old with identical findings.

BMI factor

Being overweight (BMI 25 or more) for 10 or more years is a specific SoP factor for lower limb OA (Factor 15(a)). Many veterans meet this criterion without realising it’s a standalone factor that satisfies SoP requirements.

The SoP factors DVA uses to accept your claim

Osteoarthritis SoP 61/2017 (reasonable hypothesis) and SoP 62/2017 (balance of probabilities), current compilation effective 25 July 2022. Diagnosis requires clinical manifestations and imaging or arthroscopic evidence.

How to get assessed and what evidence you need

• Imaging: X-ray of both knees (weight-bearing AP and lateral views) as the starting point. MRI provides detail on cartilage, meniscal, and ligament pathology. Get bilateral imaging even if symptoms are worse on one side.
• Specialist report from an orthopaedic surgeon or rheumatologist addressing current functional capacity, ROM measurements, gait analysis, need for aids, and the causal pathway from service activities to OA development.
• Service records: PT test records, deployment histories, injury reports, sick parade records, and unit training programs showing marching distances and load weights.
• Weight history if relying on Factor 15(a): medical records, annual health assessments, and Defence health screening records.

Common mistakes: not claiming both knees when both are affected; not claiming secondary conditions; not requesting resting joint pain assessment under Table 3.4.1; overlooking the BMI factor as a standalone SoP pathway; using GP assessments instead of orthopaedic specialist reports.

Frequently asked questions

How much is DVA compensation for a knee injury?

Knee osteoarthritis compensation under the MRCA typically ranges from $37,000 for mild unilateral cases to $171,000 or more for severe bilateral cases (lump sum, age 35, warlike service). With secondary conditions, total compensation can be substantially higher.

Can I claim DVA compensation for both knees?

Yes. If both knees have OA linked to service, each knee should be assessed. The impairment points are combined under the whole-of-person approach. Bilateral claims attract more compensation than unilateral.

Does knee replacement affect my DVA payout?

The impairment rating is based on your residual function after surgery. A successful replacement with good function may result in a lower rating than a severely arthritic knee without surgery. If you have complications, persistent stiffness, or limited range of motion post-surgery, those functional limitations are reflected in the rating.

What SoP factor covers military marching and pack carrying?

Factor 14(c) covers carrying loads of at least 20 kg for a cumulative total of at least 3,800 hours within any 10-year period. Factor 14(b) covers lifting loads to a cumulative total of 100,000 kg in 10 years. Both are commonly met by infantry, combat corps, and other physically demanding roles.

Can I claim knee OA if I am overweight?

Yes. Factor 15(a) specifically covers being overweight (BMI 25 or more) for at least 10 years before onset. This is a standalone SoP factor. Many veterans meet it without realising it satisfies the SoP requirements on its own. You’ll need weight records spanning the relevant period.

Does knee OA affect my other DVA claims?

Yes. Knee OA commonly causes altered gait, which can lead to hip OA and lumbar spondylosis. These secondary conditions can each be claimed separately with their own impairment points. Chronic knee pain can also contribute to depression claims.

How long does a DVA knee OA claim take?

MRCA initial liability claims currently average around 108 days for recently lodged claims. Knee OA in physically demanding roles may qualify for streamlined processing. The permanent impairment assessment occurs after liability is accepted and the condition has stabilised.
