The 35-year-old is expected to make a full recovery and return to competition this fall. The procedure was described as "routine" by Johnson's agent, according to Golf Channel's Ryan Lavner.
He had a similar surgery on his right knee in 2011.
Johnson struggled in the second half of the 2018-19 season. After finishing runner-up to Brooks Koepka at the PGA Championship in May, The world's No. 3-ranked golfer failed to finish inside the top 20 in his final eight events. He capped his campaign by coming in last at the Tour Championship.
The events that Johnson is slated to play in the fall are unknown. However, he's featured in the previous four WGC-HSBC Champions tournaments, which take place in late October in China. He also qualified for the 2019 Presidents Cup team heading to Melbourne, Australia, in December.
