Metta World Peace said one of the reasons he has decided on a blood-spinning therapy known as platelet-rich-plasma Jan. 6 is because it was recommended by a handful of players, including Amar’e Stoudemire.

Stoudemire never has publicly revealed he had PRP on his knees, but World Peace said it’s true.

World Peace also said Kenyon Martin has had a similar procedure. World Peace won’t play on the Texas triangle trip and said he will sit out two weeks after the procedure. meaning he should be back around Jan. 20.

Kobe Bryant and Alex Rodriguez are the two most famous athletes to recently undergo the therapy, which can help with arthritis. World Peace, according to a source, has an arthritic left knee that needed to be drained Monday for the fourth time since the regular season began.

“I spoke to Kenyon and Amar’e about it, and they’re still playing,” World Peace said. “Ama’re played a good game in Toronto [Saturday] and everybody expected him to not have a good season. I think he’s playing well when he gets minutes. Who knows, maybe the PRP did work for him.”

According to a source, Stoudemire had the PRP two years ago and not in July, when he said in training camp he had a “minor procedure” on his knee but didn’t specify.

The PRP procedure, mostly done outside the U.S., is not considered standard practice. Experts say too little medical evidence exists. But World Peace sounded desperate after his knee swelled up again after playing just five minutes vs. Toronto on Friday because the club was shorthanded. He has missed four of the past five games.
