Dobriskey was hurt in the final of the 1500m at the British Championships, which serve as trials for the Worlds, in Birmingham at the weekend
"Sadly, the scan picked up a grade three tear so I have no choice but to end my season here," she tweeted.
The 29-year-old won silver in the 2009 World Championships in Berlin but suffered injury problems in 2012.
"It is incredibly unfortunate circumstances," UK Athletics performance director Neil Black said after she pulled up in the West Midlands. "I think Lisa was spiked and there was a collision."
At London 2012 she reached the final but finished 10th, having suffered a hip injury then blood clots on her lungs in the lead-up to the Games.
The Worlds in Russia will take place from August 10-18.
