Bipartite patella Bipartite patella Bipartite patella is a condition where the patella, or kneecap, is composed of two separate bones. Instead of fusing together as normally occurs in early childhood, the bones of the patella remain separated. The condition occurs in approximately 12% of the population and is nine times more likely to occur in males than females.

Saupe introduced a classification system for Bipartite Patella back in 1921. Type 1: Fragment is located at the bottom of the kneecap (5% of cases)
