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.[1] The condition occurs in approximately 1–2% of the population[2][3] and is no more likely to occur in males than females.[2][3] It is often asymptomatic and most commonly diagnosed as an incidental finding,[1][3][4] with about 2% of cases becoming symptomatic.[2][3]
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) Type 2: Fragment is located on the lateral side of the kneecap (20% of cases) Type 3: Fragment is located on the upper lateral border of the kneecap (75% of cases)[5]
