Abstract
Thirty-five patients (28 children and seven adults) were reviewed six months to 22 years after sustaining the common childhood fracture of the intercondylar eminence of the tibia. The aim was to assess both short-term and long-term results and prognosis by clinical and radiological examination and to discover whether conservative treatment was adequate for those severe fractures where a fragment of the tibial crest had been totally displaced. All the less severe fractures and 14 of the 17 severe fractures were treated conservatively. Early improvement occurred in more patients when the knee was immobilised in extension rather than in flexion, but long-term results were similar. Seven patients had slight discomfort, two of whom had had operative treatment. Radiographs of all patients showed a projection at the fracture site but its size did not correlate with the extent of displacement of the fragment nor with the degree of discomfort suffered; in the severe group a smaller projection developed after open reduction and after immobilisation in extension than after immobilisation in flexion. There was no instability due to functional lengthening of the cruciate ligaments and no increased incidence of degenerative change.
