text: Total knee arthroplasty, TKA for short,
  Relieves the pain, restores function, that's the report.
  Osteoarthritis sufferers, listen up, I'll explain,
  When it's severe on both knees, it's a bilateral game.
  
  But hold up, there's a debate, no consensus in sight,
  When's the best time for a bilateral TKA, right?
  That's what this study's about, let's dive in deep,
  Comparing rates of revision and mortalities we'll keep.
  
  We got data from the Australian Orthopaedic Association,
  Their National Joint Replacement Registry's our foundation.
  Simultaneous and staged bilateral TKAs, the two methods we'll compare,
  To see which one's better, which one's more fair.
  
  We're talking revisions and causes, mortality in thirty days,
  Gotta analyze the stats, in so many ways.
  So, let's break it down, study the facts,
  And find the answer that the data attracts.
