Surgical Treatment for Painful Bipartite Patellae

Six cases (six knees) of the painful bipartite patellae were treated by surgical method because conservative treatment wasn't effective. The first case was treated by an excision of the accessory ossification center, but the knee pain remained. So we tried to get osteosynthesis of the bipartite patellae by peg bone autograft and all of them were treated well. As surgical treatment for painful bipartite patellae, we recommend osteosynthesis by peg bone autograft when there is no subluxation of the patella. And when there is suluxation, at first we should think of reduction of the patella for example by transposition of the tibial tuberosity.
