Hobbled for months by a hip injury, Gov. Mark Dayton will get an injection that should help him heal. 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.

From the governor's office:

"On Wednesday, October 23rd, Governor Mark Dayton will undergo a procedure at the Mayo Clinic that is designed to promote healing of the torn muscle in his left hip area. It is called a "Platelet Rich Plasma (PRP) Injection" (description below).

The procedure is expected to last approximately one hour, under local anesthesia. Afterward, he will return by car to the Governor's Residence. The general post-procedure instructions call for the PRP recipient to refrain from placing any weight on the hip for the first two days, followed by up to two weeks of very limited mobility. As such, Governor Dayton will conduct State business from the Residence during that time, and will not be holding public events.

Excerpted from Mayo's "Description of PRP and Predetermination of Benefits"

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."

Over summer, the governor popped out his hip, which he later learned was the result of an injury to his Sartorius muscle in his left hip.

Since then, the 66-year-old governor, who is running for re-election, has limited his physical activity but the hip has not healed.
