Polish-born Ola was left on crutches after damaging her knee while preparing for the Channel 4 winter sports show at the end of last year.
The injury left her unable to perform during Strictly Come Dancing's final few performances last season.
Today, the 32-year-old's dancer husband James Jordan, 36, tweeted a picture of Ola looking pensive as she lay on a hospital bed awaiting her procedure.
"Understandably Ola is looking a bit nervous as she is just about to go for surgery," said James.
While Ola was under the knife, former Celebrity Big Brother star James admitted to fans he'd felt "quite emotional" seeing his partner being wheeled away.
He'd earlier said: "I wish I could have it for her."
Ola, meanwhile, thanked fans for their messages of support ahead of her surgery – and shared the gift her nieces had brought her: fluffy pink slippers.
