King is no stranger to the medical room at Spurs and the injury-jinxed defender is hoping he won't need the operation.
"Ledley is improving and we are hoping he might be back soon," said Redknapp.
"We have got two options for Ledley - we have got a date for a lady to operate on him, she is available on the 23rd of this month so we have really got until then to make a decision.
"He is coming on well and if he feels okay we won't operate.
"But if it needs doing we will have to get him done before then."
