This article explains how SIRA assesses knee injuries in NSW CTP claims, the compensation available, and the steps to take in Bankstown. It covers threshold injury criteria, statutory benefits, and when to seek legal advice.

Current as at 20 August 2026

A threshold injury under the Motor Accident Injuries Act 2017 (NSW) includes a soft tissue injury and a psychological or psychiatric injury that is not a recognised psychiatric illness (adjustment disorder and acute stress disorder are the usual examples; s 1.6 and Motor Accident Guidelines Part 5).

If you've suffered a knee injury in a motor vehicle accident in NSW, understanding how SIRA evaluates your claim is critical. SIRA (State Insurance Regulatory Authority) administers the Compulsory Third Party (CTP) scheme, which provides compensation for injuries caused by motor vehicle accidents. This article explains how SIRA assesses knee injuries, the types of compensation available, and the practical steps to take in Bankstown.

How SIRA Assesses Knee Injuries

SIRA uses the Motor Accident Guidelines to determine the severity of injuries. For knee injuries, this includes ligament tears, joint instability, and cartilage damage. Under the Motor Accident Injuries Act 2017, injuries must meet the 'threshold injury' criteria to qualify for statutory benefits. This means the injury must result in a measurable impact on your daily life, such as difficulty walking, prolonged recovery, or reduced mobility.

SIRA also considers whether your knee injury meets the 'spinal nerve-root' qualification. For example, a tear in the anterior cruciate ligament (ACL) or meniscus may qualify as a threshold injury if it causes neurological signs like pain radiating down the leg. However, radiculopathy (nerve root compression) requires specific clinical signs, such as muscle weakness or reflex changes, to be included in the assessment.

Types of Compensation Available

If your knee injury meets the threshold criteria, you may be eligible for:

  • Weekly benefits, Payments for 52 weeks to cover lost income.
  • Treatment and care benefits, Funding for medical treatment, physiotherapy, and equipment.
  • Damages, If your injury results in long-term impairment (e.g., chronic instability or arthritis), you may claim additional compensation for pain, loss of enjoyment, and future care needs.

Note: Statutory benefits are limited to 52 weeks for 'only injuries' (injuries that don't meet the threshold). If your knee injury is classified as a threshold injury, benefits may continue beyond 52 weeks depending on the severity.

Practical Steps for Bankstown Residents

To support your claim, gather:

  • Medical records, Including MRI scans, physiotherapy notes, and specialist reports.
  • Accident details, Police reports, witness statements, and photos of the scene.
  • Evidence of impact, Documentation of how your injury affects your work, family, or daily activities (e.g., reduced mobility, inability to walk long distances).

SIRA requires these records to assess whether your knee injury meets the threshold and to determine the appropriate level of compensation.

Time Limits and Dispute Options

CTP claims must be submitted within 52 weeks of the accident. If your injury doesn't meet the threshold, you may still pursue a common law damages claim through the courts, but this requires legal advice.

If SIRA disputes your claim, you can request a review by providing additional evidence. In complex cases, legal representation may be necessary to challenge SIRA's assessment.
