Khalida Chowdhery, from Woodford Green in North East London, was left with a life-threatening condition after errors during the knee operation left her with a damaged artery.
Following the procedure, Mrs Chowdhery woke up in serious pain and reported that her foot felt cold. This continued for three days but, rather than examine the problem, staff at the Whipps Cross Hospital simply increased her pain medication.
At one point, the pain was so severe that the 66-year-old mother of three was pleading with staff to remove her leg.
It was not until four days after Mrs Chowdhery awoke from the operation that doctors discovered that the main artery had become damaged and that pressure inside her leg muscles was preventing the flow of blood to her leg.
She was transferred to the Royal London Hospital, where surgeons had no choice but to amputate her leg.
Whipps Cross has since apologised for the errors, offering its “deep and sincere” regrets that it failed in its duty of care. The family are now bringing a medical negligence claim against Barts Health NHS Trust.
Mark Bowman, a clinical negligence solicitor from Field Fisher Waterhouse, said: “What should have been a routine operation leading to real benefits for Mrs Chowdhery has instead left her and her family devastated.”
He added: “The circumstances of this case are quite extraordinary and the way in which Mrs Chowdhery was treated following her surgery was utterly appalling.”
