大多数青少年的骨软骨损伤通常被认为是骨软骨骨折。然而，我们报告了三例青少年纯膝关节软骨碎片。患者在体育活动中受伤，因此膝关节活动度急性受限。3例中仅1例可通过MRI确诊，其余2例需关节镜检查确诊。使用生物可吸收针重新固定骨折块。所有患者最终都能够恢复到以前的体育活动水平。术后2年，他们没有出现任何症状，MRI显示重新固定的碎片连续到床上，没有任何异常的介入信号区，表明成功愈合。此外，关节镜下重新固定的碎片与周围关节软骨之间的整合是可以接受的。活跃青少年的股骨外侧髁软骨碎片应被认为是一个明确的实体，可以通过重新固定成功治疗。(C)2012 Elsevier B.V.保留所有权利。
Most injuries to the osteochondral region in adolescents have generally been believed to occur as osteochondral fractures. However, we report three cases of pure chondral fragments of the knee in adolescents. The patients were injured during sports activities and as a result had acute limitation of ROM of the knee joint. Only one case out of three could be diagnosed by MRI, and arthroscopic examinations were needed to make a final diagnosis in the remaining two cases. Re-fixation of the fragments was performed using bio-absorbable pins. All the patients were eventually able to return to their previous level of sports activity. Two years after the operation they experienced no symptoms and MRI showed that the re-fixed fragments were continuous to the bed without any abnormal intervening signal area, suggesting successful healing. Moreover, the arthroscopic integration between the re-fixed fragment and the surrounding articular cartilage was acceptable. Chondral fragment of the lateral femoral trochlea in active adolescents should be recognized as a clear entity that can be successfully treated by re-fixation. (C) 2012 Elsevier B.V.
