Knee Injuries in NSW CTP Claims: Dispute Resolution Options in Auburn

This article explains dispute resolution options for knee injuries in NSW CTP claims, including SIRA's assessment process, evidence requirements, and pathways for challenging decisions. It highlights the importance of medical records, time limits, and legal advice for resolving disputes in Auburn.

Current as at 6 October 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 accident in NSW and are disputing your compensation, understanding your options is critical. Under the NSW Compulsory Third Party (CTP) scheme, disputes over knee injuries often hinge on medical evidence, SIRA's assessment process, and available review pathways. This article explains how to challenge a decision, what evidence matters, and when to seek legal advice.

How SIRA Assesses Knee Injury Claims

SIRA evaluates knee injuries based on the Motor Accident Guidelines and the Motor Accident Injuries Act 2017. For example, ligament tears or meniscus damage may qualify as 'threshold injuries' if they meet specific clinical criteria, such as neurological signs or functional limitations. SIRA considers medical reports from registered practitioners, imaging results, and treatment records to determine eligibility for weekly payments, treatment benefits, or damages.

If you disagree with SIRA's decision, you can request an internal review by the Claims Resolution Unit. This process allows for a reassessment of medical evidence or interpretation of guidelines. If the review upholds the decision, you may escalate the matter to the Personal Injury Commission (PIC) for a formal dispute. The PIC can order an independent medical assessment if there's a disagreement about the injury's severity or long-term impact.

Evidence Needed for Knee Injury Claims

To support your claim, gather: medical records detailing the injury's diagnosis and treatment, accident reports from the NSW Police or CTP insurer, witness statements, and evidence of income loss. For disputes, SIRA will scrutinise whether the injury meets the 'threshold injury' definition under the Act, which requires a spinal nerve-root injury producing neurological signs beyond radiculopathy.

Time Limits and When to Seek Advice

You have 52 weeks from the accident date to claim weekly benefits for threshold injuries. After this period, benefits may stop unless the injury is classified as a 'whole person impairment' under the guidelines. If your claim is denied or disputed, act quickly: SIRA's internal review must be requested within 28 days of receiving the decision. Legal advice is essential if you face a PIC dispute, as these processes can take months and require detailed medical evidence.

Practical Example: Challenging a Threshold Injury Decision

Consider a claimant who suffered a torn ACL and meniscus tear in a car accident. SIRA initially denied weekly payments, citing the injury as a 'threshold injury' under the Act. The claimant disputes this, arguing the injury caused long-term mobility issues. They request an internal review, submit additional MRI scans, and later challenge the decision at the PIC. The outcome depends on whether the injury meets the 'neurological signs' criterion and the PIC's interpretation of the guidelines.

Next Steps

CTP disputes involving knee injuries require careful navigation of SIRA's assessment process, medical evidence standards, and review timelines. If you're unsure whether your claim meets the criteria or need help challenging a decision, contact a legal professional. Every claim depends on its own facts, and the right support can make a difference.
