Three cases of patellar fatigue fracture are reviewed. Two fractures presented with acute displacement and were initially thought to represent pathological fractures. Histological appearances in one case, and the clinical course in another, subsequently indicated that these were fatigue fractures. A third patient developed a chronic undisplaced fracture and followed the typical clinical course of fatigue fractures at other sites. The importance of recognizing patellar fatigue fractures and of differentiating spontaneously displaced fatigue fractures from pathological fractures is emphasized.
本文回顾了三例髌骨疲劳性骨折。两例骨折出现急性移位，最初被认为是病理性骨折。其中一例的组织学表现以及另一例的临床病程，随后表明这些是疲劳性骨折。第三位患者发生了慢性无移位骨折，并遵循了其他部位疲劳性骨折的典型临床病程。强调了认识髌骨疲劳性骨折以及区分自发性移位疲劳性骨折与病理性骨折的重要性。
