Andrew Bynum for 2015?

The 7-foot Bynum may not be reuniting with Phil Jackson’s Knicks or any other team next season because he is seriously contemplating sitting out 2014-15 to undergo the Germany-based knee therapy called “The Regenokine Program’’ that would require an extra long rehab, according to his agent David Lee. But he could be in play for the following season.

Regenokine is a non-surgical program that promotes new cartilage growth through a series of injections. The FDA still hasn’t approved it in the United States. Bynum is considering doing the program with well-known doctor German doctor Peter Wehling, who worked with Kobe Bryant and Alex Rodriguez. It is similar but not identical to the PRP procedure.

Bynum has arthritic knees that have stalled a career that once flourished under Jackson in Los Angeles.

“If he’s healthy, Phil will be interested,’’ Lee told The Post. “Phil knew how to tap into Andrew. They got along famously.’’

Bynum, the Jersey product who was a young stud center for two of Jackson’s Lakers title teams, would undergo the procedure as a means to extend his career.

“He would be looking at in a longer-term situation,’’ Lee said. “He’s still a baby. If he went to college, he’d be coming off his rookie contract at age 26.’’

The Knicks pursued Bynum last February before Jackson came aboard, but he signed with the Pacers, though he couldn’t remain healthy. He played 26 games last season: 24 with Cleveland before being waived for disciplinary reasons and two with the Pacers.

The Knicks will be in need of centers in 2015. All of their big men are on expiring contracts: Samuel Dalembert, Amar’e Stoudemire, Andrea Bargnani and newly signed Jason Smith.
