- In cadaveric studies, a trilaminar prepatellar bursa was found in 78-93% of people, and a bilaminar bursa was found in 7-22% cases
- 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).
