It turns out the incredible physical specimen that is Adrian Peterson was apparent to surgeons operating on the running back’s knee last year.
In an interview with NFL.com, Peterson’s parents recall a discussion with AP’s surgeon, Dr. James Andrews. Andrews told them their son has one of the most phenomenal knees he’s ever seen especially for someone who’s played so much football.
The surgeon compared the condition of Peterson’s knee to a “newborn baby,” with hardly any wear and tear.
