Earlier this month, King dismissed suggestions he may have to retire because of the injury.
He said: "It's just talk. I'm not retiring, let's put it that way. I honestly believe that when I do finally get it all right there won't be any more problems in the future."
In the same magazine interview, the former Spurs trainee revealed that he had been playing with an injured knee "for a few seasons". But King was optimistic about making a full recovery by August.
