Ms McPhail was in such pain she often had to use crutches and was unable to walk the 800m to university from her room. The harm to her emotional wellbeing, social relationships and ability to study and support herself financially was becoming too great.
"My parents had to foot the bill for surgery because it got to the point where I was in so much pain I had to be rushed to the after-hours clinic to have a morphine injection."
Now she is faced with trying to recover the money from ACC. Her problems began in June 2010 at a university hostel when she twisted badly as she rose from a chair to go for lunch.
A highly active sportswoman and first-year student aged 18, she underwent scans and conservative treatment for several months before orthopaedic surgeon John Rietveld recommended keyhole surgery to repair a tear in the labrum, the ring of soft, elastic tissue around the rim of the hip socket which holds the ball in place.
ACC, which until then had covered her injury, withheld surgery funding, saying she had a congenital condition called joint hyper-mobility syndrome.
Cover can be refused if an injury is wholly or substantially caused by a non-work disease or gradual process. The courts have defined "substantially" as more than 80 per cent.
"I have never officially been diagnosed with [the] syndrome," said Ms McPhail.
Quoting Mr Rietveld's report, she said he had some concerns about the flexibility of her joints, but had stated it was not the cause of her hip problems.
During surgery, he found the damage was much worse than thought. But the operation succeeded and she feels as if her hip has been fixed. "Three weeks post-op and I can walk [1.3km] to university without any pain."
She said ACC took around six months to refuse surgery funding. Delays also occurred in the new assessment ordered by the reviewer. The day before her operation, ACC told her the surgeon it had arranged in Auckland had pulled out of doing the job.
A corporation spokeswoman said: "ACC accepts that the elapsed time to make a decision on funding Ms McPhail's surgery has been too long. ACC will contact Ms McPhail directly to resolve the situation as a matter of priority. ACC regrets the situation."
