Review Articles with Critical Analysis Component

  • * Patellar fractures occur as a result of a direct blow to the knee and/or as a result of tension when the forces generated between the quadriceps tendon and patellar tendon overcome the strength of the bone.
  • * Patellar fractures that include a functional disruption to the extensor mechanism should be treated with stable open reduction and internal fixation.
  • * If necessary, partial (or, rarely, complete) excision of the patella can be performed to provide a stable extensor mechanism repair.
  • * Acute quadriceps and patellar tendon ruptures, if complete, require primary repair.
  • * Delayed intervention for any complete extensor mechanism disruption may result in the need for reconstruction, augmentation, or advanced techniques to facilitate early motion.
