Abstract
The patella is a sesamoid bone that connects the quadriceps tendon and the patella ligament. Medially and laterally, the patella is supported by the retinacula. Biomechanically the patella shifts the lever arm anterior and increases the extension power of the quadriceps muscle up to 50 %. In downhill walking, the pressure on the femoropatellar joint increases from 3.3 to 7.6 times. Therefore, the demands on the osteosynthesis are very high.
