Dr Al Muderis is suing Nine for defamation in the Federal Court over a series of reports he claims ruined his reputation and set back the field of prosthetic limbs by 20 years.
The reports featured in The Sydney Morning Herald and The Age newspapers and aired on 60 Minutes in September 2022.
Nine defends the claims as true or otherwise protected as journalism in the public interest.
The company's barrister, Matthew Collins KC, resumed questioning of Dr Al Muderis on Tuesday, asking about the use of a "suction pump" on a patient, which the surgeon said was scientifically known as a "vacuum dressing".
The procedure was used to drain fluid, relieve swelling and close wounds.
Dr Collins said the patient reported being in agony, a claim Dr Al Muderis disputed.
"The vacuum dressing does not cause pain," he said, adding that he did not recall the patient telling him she was in agony.
Asked if she begged not to have the dressing applied, Dr Al Muderis called the question absurd.
"How would she know, a vacuum dressing or the type of dressing, it's a dressing that I choose based on the necessity of the closure, patients don't normally know about that," he said.
When asked if the patient said not to use it again because it hurt too much, Dr Al Muderis responded: "If she had said that to me, I would not have done it."
The patient, who wanted mobility to assist her husband as his health deteriorated, later wrote to Dr Al Muderis complaining that she felt their conversations were unsatisfactory and that her concerns were not being taken seriously.
Dr Al Muderis agreed that was what the letter said but contended it was wrong.
She underwent a successful surgery but unfortunately suffered from a recognised complication she was warned about, which he treated.
The surgeon said he attended to the patient in a timely fashion and managed her complaints and complications on a regular basis.
"If she decided to discontinue being treated by me, as much as it saddens me … I can't do anything about it," Dr Al Muderis said.
"I can't comment on people giving her other advices, I can't comment on her feelings, all I can do is to provide the patient with the best care to the best of my ability, which I believe that I have done."
The hearing continues.
