The Duke of Edinburgh underwent surgery for a hip replacement Wednesday after he'd been admitted to the hospital the day before for the planned surgery. The palace later said that he was progressing satisfactorily after the surgery, but had to remain in the hospital for approximately two weeks.
He also missed the Easter Sunday service traditionally attended by the royal family at St George's Chapel in Windsor to the west of London, where his grandson Prince Harry is due to marry US actress Meghan Markle next month.
Philip stepped down from his public duties last summer, but on occasion attends events with the Queen. "That's more important than someone's chronological age".
The aging royal did not attend Easter services with the Queen over the weekend because he was having problems with his hip. In June 2017, the Duke was admitted to hospital for an infection stemming from a pre-existing condition but was back in working order for celebrations at Sandringham over the Christmas holiday.
His surgery comes ahead of a busy time for the royal family, with Kate Middleton, Duchess of Cambridge, due to give birth to her third child some time this month, and the wedding of his grandson, Prince Harry, with Meghan Markle on May 19. When it was announced past year that he would be retiring from official engagements, Buckingham Palace stressed that the decision was not health-related and that he had the full support of the Queen.
In May 2014, he had a "minor procedure" on his right hand, with the treatment carried out inside Buckingham Palace.
Details about which of the duke's hip joints was replaced have not been released by Buckingham Palace.
Generally, Prince Philip has spent his life in good health.
Figures for the United Kingdom, excluding Scotland, show 851 people over 90 had a hip replacement in 2016.
