text: Yo, check it out, I got a story to tell
  'Bout navigation in joint arthroplasty, it rings a bell
  They say it helps with component placement, no doubt
  But watch out for complications, that's what it's about
  
  Gross fractures and stress fractures, they can occur
  When navigation tracker pins ain't placed secure
  Three patients out of two-twenty had a stressful ride
  With stress fractures in the tibial shaft, they couldn't hide
  
  But don't worry, y'all, it all turned out fine
  After some time with protected weight, they did shine
  Now we play it safe, using smaller-diameter pins
  Self-tapping, self-drilling, that's where the solution begins
  
  No more pins in the diaphysis, that's the rule
  We insert 'em in different plains, ain't no fool
  When it comes to metaphysis, we know what to do
  Keepin' it smooth, keepin' it true
  
  So remember this tale, when you're doin' your thing
  In total knee arthroplasty, let the knowledge ring
  Navigation's a tool, but watch the pin placement
  Keep it on point, avoid any complications, no replacement
