Venizelou v AAI Ltd

Venizelou v AAI Ltd involved a dispute regarding the impact of a motor accident on the claimant's pre-existing knee condition. The claimant had fallen as a passenger on a bus in 2020 and subsequently experienced increased symptoms and recurrent locking in her left knee. The court was tasked with determining whether the motor accident had aggravated her pre-existing arthritic condition and accelerated the need for knee surgery, which was ultimately performed in mid-2021.

The key legal issues before the court were whether the motor accident constituted a non-minor injury under section 1.6 of the Motor Accident Injuries Act 2017 (MAI Act) and if the accident materially contributed to the need for surgery. The court considered whether the accident had aggravated the pre-existing condition and whether the surgery was reasonable and necessary in the circumstances. The claimant argued that the accident significantly worsened her condition and brought forward the need for surgery, while the defendant contested the extent of the injury.

The court found that the motor accident had indeed aggravated and accelerated the degenerative changes in the claimant's knee, leading to further tearing of a degenerate lateral meniscus. The panel accepted that the accident significantly increased the claimant's symptoms and brought forward the need for surgery, which was deemed appropriate and required by unanimous medical evidence. The court applied principles from AAI Ltd v Phillips and referenced Secretary, Department of Education v Johnson in reaching its decision. The original medical assessment was revoked in light of the new evidence and findings.

The court concluded that the motor accident was a non-minor injury as it materially contributed to the need for treatment. The claimant's surgery was deemed reasonable and necessary, and the decision recognised the significant impact of the accident on the claimant's pre-existing condition. The court ordered the defendant to cover the costs associated with the surgery and any related treatment, acknowledging the substantial worsening of the claimant's condition as a result of the motor accident.
