    ObjectiveTo analyze the characteristics of children tibial intercondylar eminence fractures, and introduce arthroscopic minimally invasive techniques for the treatment of tibial intercondylar eminence fractures in children.MethodsFrom January 2004 to December 2008, 12 children with tibial intercondylar eminence fractures were treated with cross Kirschner wire fixation after arthroscopic reduction. According to Meyers-McKeever classification systems, there were 1 case of type I, 4 cases of type II, and 7 cases of type III. There were 10 fresh and 2 old fractures in all. Among the patients, 10 patients were boy and 2 patients were girl,ranging in age from 8 to 13 years, with an average of 10 years. All the patients underwent arthroscopic exploration, reduction and fixation. During follow-up ranging from 10 to 36 months, the union of fracture, range of motion and stabilization of the knee were assessed. One patient was combined with lesions of the menisci, 1 patient with femoral trochlea cartilage injury, and 5 patients with meniscal entrapment under the bone.ResultsThe heeling time averaged 5 weeks. No knee laxity or instability and no intercondylar notch impingement was detected in all cases at 3 months postoperatively. At same time, full range of motion of the affected knee returned, and the average Lysholm knee score was (92.7 +/- 2.5), the average Lysholm knee score was (96.4 +/- 1.7) at 6 months postoperatively. The Lachman test and ADT test was negative.ConclusionThe type II and type III tibial intercondylar eminence fractures occur frequently in children. Lesions of the menisci and cartilage occur seldom. The method of arthroscopic cross Kirschner wire fixation for the treatment of tibial intercondylar eminence fracture is easy to operate. Simultaneously, this technique is less invasive and allows early recovery. Also it coincidences with the characteristic rapid bone growth of children.
