The Duke of Edinburgh will undergo planned surgery on his hip at King Edward VII Hospital on Wednesday. He was hospitalized at King Edward VII Hospital in Marylebone.

The Duke of Edinburgh is "comfortable and in good spirits" after a successful hip replacement operation, Buckingham Palace has said.

It is expected that Buckingham Palace will provide updates where appropriate.

He has missed a series of engagements and events over the last month, including the recent Easter Sunday service at St. George's Chapel in Windsor.

Philip was an avid sportsman for many years and saw active duty in the Royal Navy during World War II. His retirement included retiring from attending events for his own charities and organization. At that time, he was supposed to attend the State opening of Parliament with Queen Elizabeth. At that time, he was seen having trouble standing and leaning against a wall.

The Queen and Prince Philip celebrated their 70th wedding anniversary last November.

In December 2011, the prince suffered from chest pain and had to have a minor surgery to open a blocked artery.

In June 2017, he spent two nights in hospital as a "precautionary measure" for the treatment of an undisclosed infection. When it was announced a year ago 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. It said the hospital admission and surgery were planned.

PRINCE Philip is in "good spirits" after undergoing a successful surgery on his hip, Buckingham Palace has said.

Most hip replacements are carried out on patients between the ages of 60 and 80 but overall fitness is a bigger factor than age in any decision to operate.
