Gov. Mark Dayton will have a medical procedure Wednesday at the Mayo Clinic in Rochester to help speed recovery of a torn hip muscle.

The governor’s office said the procedure, a Platelet Rich Plasma (PRP) Injection, will take one hour, after which he’ll return by car to the governor’s residence in St. Paul.

For the next two days, he’s not supposed to put any weight on the hip, and then he’ll have two weeks of  limited mobility. Dayton will  conduct some state business from the Governor’s Residence during the recovery period, but won’t hold  public events.

This is the second Mayo visit for the 66-yeasr-old Dayton in the past year. Last winter, during the holidays, he had back surgery to correct a constriction of the spine. He was sidelined for the first few weeks of January, conducting some business out of the governor’s residence on Summit Avenue.

Dayton tore a hip muscle in mid-June, causing much discomfort and some limitations on his schedule.

Wednesday’s procedure is designed to help promote healing of that torn muscle.

Bob Hume, the governor’s deputy chief of staff, described the procedure in an alert to the media:

Platelet rich plasma (PRP) is a non-toxic, non-immune substance that accelerates healing. PRP is produced from the person’s own blood using a process called platelet enrichment activation. This process allows the extraction of platelets from regular blood and their concentration to over 5 times normal.  These concentrated platelets are then injected into the injured muscle to promote healing.
