Summary

Aspiration of air after double-contrast knee arthrography significantly reduces immediate pain and discomfort. This procedure, known as knee arthrography, improves patient outcomes by minimizing short-term morbidity.

Area of Science:

  • Orthopedic Surgery
  • Radiology
  • Medical Imaging

Background:

  • Double-contrast knee arthrography is a diagnostic imaging technique.
  • Post-procedure pain and discomfort are common patient complaints.

Purpose of the Study:

  • To compare short-term pain and discomfort after knee arthrography.
  • To evaluate the effect of air aspiration on patient morbidity.

Main Methods:

  • Prospective study comparing two groups undergoing knee arthrography.
  • One group had air aspirated post-procedure; the other did not.
  • Pain and discomfort assessed immediately and 7 days post-procedure.

Main Results:

  • Immediately after the procedure, 48% of the aspirated group were asymptomatic versus 22% in the non-aspirated group.

  • By 7 days post-procedure, asymptomatic rates were similar (64% vs. 63%).
  • Air aspiration significantly reduced immediate post-arthrography morbidity.

    • Conclusions:

    • Air aspiration following double-contrast knee arthrography alleviates short-term pain.
    • This simple modification can improve patient comfort and reduce immediate morbidity.
    • Knee arthrography outcomes can be enhanced by routine air aspiration.
