Dayton To Undergo Mayo Procedure For Torn Hip

ST. PAUL (AP) - Gov. Mark Dayton is returning to Mayo Clinic in Rochester for a procedure meant to help heal a torn muscle in his left hip area.

Dayton's office released details Monday of the upcoming procedure. It's known as a "platelet rich plasma injection," or PRP, and involves the extraction of concentrated platelets from the patient's blood that are injected into injured muscle.

Dayton is scheduled to undergo the approximately hour-long procedure on Wednesday, under local anesthesia. His office says he will have limited mobility for two weeks following the procedure, and that he will refrain from public events and conduct business at the governor's residence during that time.

The 66-year-old governor tore a hip muscle in June. He was also sidelined for several weeks last winter after back surgery at Mayo.
