Magnetic resonance (MR) imaging for knee injuries proves cost-effective. This advanced imaging technique significantly reduces the need for diagnostic arthroscopy, saving both time and money for patients.

Area of Science:

  • Orthopedics
  • Radiology
  • Health Economics

Background:

  • Diagnostic arthroscopy of the knee is an invasive procedure.
  • The cost-effectiveness and impact on the need for arthroscopy of MR imaging for knee injuries require evaluation.

Purpose of the Study:

  • To determine if magnetic resonance (MR) imaging is cost-effective for knee injuries.
  • To assess whether MR imaging can reduce the necessity for diagnostic knee arthroscopy.

Main Methods:

  • 103 consecutive patients with knee injuries underwent MR imaging.
  • MR images were interpreted by a consensus of three radiologists.
  • Outcomes were compared between patients who did and did not undergo arthroscopy after MR imaging.

Main Results:

  • 53 patients (51.4%) avoided potentially unnecessary diagnostic arthroscopy due to MR imaging findings.
  • The study resulted in a net savings of $103,700 for the 103 patients.
  • 89% of patients who avoided arthroscopy had successful outcomes, with 40 regaining normal function.

Conclusions:

  • MR imaging is a cost-effective tool for evaluating knee injuries.
  • Utilizing MR imaging can significantly decrease the requirement for diagnostic knee arthroscopy.
  • This approach leads to substantial cost savings and avoids unnecessary invasive procedures.
