According to the Oklahoman, OKC Thunder center Kendrick Perkins underwent arthroscopic surgery on his right knee on Tuesday. This marks the second summer in a row that Perk has had surgery after saying he didn’t require it: “The scope, while considered routine for players with previous injuries, is not something Perkins envisioned needing this summer. He insisted at his exit interview in May that he didn’t require any type of surgery this offseason. Perkins also said last month that he was “excited” about the prospects of finally going through a summer surgery-free. ‘To be honest with you, I was excited about this summer, being able to work on my game,’ Perkins said during an appearance at a team-sponsored youth camp. ‘This is my first summer without having surgery, so I’m just excited about it. I definitely didn’t like how I finished the season this past season, or the postseason. I was kind of embarrassed about the way I played. So the only way to go about it is to go back to the drawing board, and I’m just treating this summer like I’m a rookie again.’ [...] Last July, Perkins had surgery to repair a partially torn right groin that plagued him throughout the 2012 postseason. He had previously said the injury wouldn’t require surgery. One week later, Perkins had surgery to repair a torn ligament in his left wrist.”
