Carr first announced his retirement in December 2008 at the age of 32 after failing to find a club following his release from Newcastle, but was persuaded to reconsider by Birmingham in February the following year.
"I am going on 37 and now is the time to bow out," Carr told Birmingham's official website. "I felt okay in pre-season but my knee just crumbled away.
"Three operations in 18 months basically told me it had had enough. It just wasn't meant to be in the end.
"The fans have been brilliant with me since I came in and I have had a great relationship with them.
"I will never forget that day lifting the cup. It was a big, big thing for me."
Carr made over 100 appearances for Blues, and as captain led the club to a ninth-placed finish in the Barclays Premier League in 2010 and Carling Cup glory a year later.
