Chondral lesions are relatively common and they usually occur as a result of high energy trauma. Chondral fractures of the patella ordinarily occur during an acute dislocation of the patella. Patellar chondral fractures without either a dislocation or a patella fracture are extremely rare. We have treated a 25-year-old male who had a unicortical transverse osteochondral fracture of the patella without a dislocation which was produced by high energy trauma. Chondral fractures of the patella are often overlooked because they are difficult to detect on plain radiographs. A persistent cartilaginous irregularity from either a chondral or osteochondral fracture may lead to the development of secondary osteoarthrosis. In this case, restoration of the articular surface was achieved by elevation of the compressed osteochondral fragment. This case demonstrates that understanding the mechanism of injury can be helpful in the treatment of osteochondral lesions.
软骨损伤相对常见，通常是高能创伤的结果。髌骨软骨骨折通常发生在髌骨急性脱位期间。没有脱位或髌骨骨折的髌骨软骨骨折极为罕见。我们治疗了一名25岁男性，他因高能创伤导致髌骨单皮质横向骨软骨骨折但无脱位。髌骨软骨骨折常被忽视，因为在X线平片上很难检测到。软骨或骨软骨骨折导致的持续性软骨不规则可能会导致继发性骨关节炎的发展。在本病例中，通过抬高压缩的骨软骨碎片实现了关节面的恢复。该病例表明，了解损伤机制有助于治疗骨软骨损伤。
