Vikings Peterson has successful surgery to repair knee

Running back Adrian Peterson's surgery to repair the lateral meniscus in his right knee was successful, the Vikings said in a news release Thursday morning.


Running back Adrian Peterson’s surgery to repair the lateral meniscus in his right knee was successful, the Vikings said in a news release Thursday morning.

Team physician Chris Larson performed the surgery at Twin Cities Orthopedics. He found no additional injuries or issues in or surrounding the knee joint during the procedure, the statement said.

Although the Vikings did not announce a timetable for his return, he is expected to be out until at least December.

“The rehabilitation process will begin immediately,” the team said.

Peterson was injured in the third quarter of Sunday night’s 17-14 victory over Green Bay at U.S. Bank Stadium. Jerick McKinnon will be the starting running back Sunday at Carolina.


Peterson told ESPN on Wednesday that he has a “bucket handle tear,” which is more severe than a typical meniscus tear.

The Pioneer Press spoke Wednesday with two doctors who have performed repair surgeries for torn meniscus injuries on pro athletes. One speculated that a repair for such an injury would keep Peterson out for three to four months; the other said the injury could sideline him for six months or more.

Had Peterson had surgery to trim out the torn meniscus, he might have been able to return in weeks. However, doctors say such a surgery would have resulted in the risk of having arthritis later in his life.

The Vikings, who conclude the regular season Jan. 1 against Chicago, have not put Peterson on injured reserve. They could place him on injured reserve and designate him to return later in the season. He then would have to miss at least eight weeks.

In previous seasons, a player put on injured reserve with a designation to return, had to be named immediately, but that rule was changed this year. Teams now can wait before designating a player to return, but only can put one player per season on that list.
