Research Review Summary

Prevalence of knee osteoarthritis features on magnetic resonance imaging in asymptomatic uninjured adults: a systematic review and meta-analysis

Key takeaways:
  • The prevalence of knee osteoarthritis features on MRI in otherwise healthy, asymptomatic, uninjured knees is high— up to 43%
  • Prevalence of knee findings on imaging almost always increases with age
  • It is inappropriate to use imaging findings as a sole determining factor in clinical care


Systematic Literature Review of Imaging Features of Spinal Degeneration in Asymptomatic Populations

Key takeaways:
  • Changing from “degenerative changes” to “normal aging changes” is a more accurate descriptor of imaging findings
  • Up to 37% of asymptomatic individuals in their 20s have disc degeneration
  • Prevalence of findings on imaging in asymptomatic population increases with age
