The Pistons said the procedure Wednesday was successful and addressed the issue that caused soreness in the knee across the last two weeks of the regular season and the postseason. They said Griffin is expected to be fully recovered before the start of training camp in September.
The 30-year-old forward mostly avoided injury this season, playing in 72 games, but he missed four of the final six regular-season games and the first two of the Pistons' first-round playoff series against the Milwaukee Bucks because of the troublesome left knee injury.
He averaged a career-high 24.5 points per game, along with 7.5 rebounds and 5.4 assists. He also made a career-high 189 3-pointers, shooting 36 percent from beyond the arc. This is the most games he has played since he appeared in 80 in 2013-14 with the Los Angeles Clippers.
