摘　　要：To the Editor:Sleeve fracture of the patella is considered as a unique type of patellar injury to the pediatric population.It is a special type of avulsion fracture in which the avulsed fragment comprises of a small bony fragment from the patella,accompanied by a large portion of articular cartilage.[1]It makes up approximately half of patellar fracture in children.[2]However,the occurrence of this injury bilaterally is extremely rare and there has been only few reports regarding the treatment and prognosis to this injury during its chronic phase.Here we reported a case of chronic bilateral sleeve fracture of the patellae in a 13-year-old healthy boy,who got injured in a running competition.To the author’s best knowledge,this is the first case of chronic bilateral sleeve fracture of the patellae in current English literature.
