Prepatellar Bursa

From WikiSM
Jump to: navigation, search


  • In cadaveric studies, a trilaminar prepatellar bursa was found in 78-93% of people, and a bilaminar bursa was found in 7-22% cases[1]
  • The prepatellar bursa does not communicate with the joint space
  • The prepatellar bursa is a flat, round, synovial-lined structure
  • This bursa is superficial, suggesting that it is undeveloped at birth.
  • Within the first few months to years of life, the bursa arises from direct pressure and friction.



  • Separate the Patella from the patellar tendon and skin.
  • Reduce friction between the skin and the patella and allows maximal range of motion (ROM).
