Recent COVID Diagnosis is Associated with Serious — Even Lethal — Risk After Elective Arthroplasty

The idea that COVID is associated with problems after surgery was well known, but the risk magnitudes here were shocking

Recent COVID Diagnosis is Associated with Serious — Even Lethal — Risk After Elective Arthroplasty
💡
Smart Practice: Postpone elective arthroplasty surgery for a month after a diagnosis of COVID.

What’s the Claim?

A large-database study using a national COVID-specific database found that patients who underwent elective THA or TKA despite a positive pre-op test for COVID within two weeks of surgery were at much higher risk for serious complications after arthroplasty, including:

  • Pneumonia (odds ratio [OR] 2.5 [95% CI 1.4 to 4.2])
  • Postoperative myocardial infarction (OR 2.9 [95% CI 1.3 to 6.2])
  • Sepsis within 90 days (OR 2.6 [95% CI 1.4 to 4.8])
  • 30-day mortality (OR 10.6 [95% CI 5.1 to 22]).

The risks fell away pretty quickly over time, with no COVID-associated risk increases identified in patients who waited more than a month after a positive COVID test to have elective joint replacement.
