Adams, Olympic champion in 2008 and 2012, had shoulder and elbow surgery last year and decided not to defend her title at the world athletics championships in Beijing this month after a disappointing season.
She said earlier this month that she would need treatment on her right knee and on Tuesday the 30-year-old posted a picture of herself recovering from her latest surgery on social media.
Germany's Christina Schwanitz has dominated the women's shot this season having ended Adams' five-year, 56-competition unbeaten streak in Paris in July.
Adams, who had won the past four world championship titles, has a best throw of 18.79 metres in competition this season, well below her personal best of the 21.24 that she threw in Daegu, South Korea in 2011.
