Introduction:

Fourteen cases of sleeve fractures of the upper pole of the patella have been reported in the Japanese literature, but only one in the English literature (Bishay, 1991). We describe a 30 year old man with a sleeve fracture of the upper pole of the patella. Type 1 osteogenesis imperfecta according to Sillence's classification (Sillence and Rimoin, 1978) was diagnosed.

Case Report

A 30 year old man fell down while walking and felt a severe pain above the left patella.. He could not walk at all and was admitted to the emergency unit of our hospital. Two months before injury, he also fell down while walking and had severe knee joint pain on walking. He was diagnosed as having an internal derangement of the left knee. The pain had been relieved by conservative treatment, but knee flexion was restricted up to 90° at the time of the injury. His knee was thus forcefully flexed in the most recent injury.
