Tomić S, Lesić A, Bumbasirević M, Sopta J, Rakocević Z, Atkinson HD - J Orthop Surg Res (2010)

Bottom Line: At 13 years follow-up there are no signs of disease recurrence or failure at the fusion site.The patient is able to fully weight bear and stand independently on the operated leg.The case is discussed with reference to the literature.

ABSTRACT
This case report describes the management of a 15 year old male with a biologically aggressive chondroblastoma of the knee. Following CT, bone scan, angiography and an open biopsy, the diagnosis was confirmed histologically and immunohistochemically. The patient underwent a 13 cm en-bloc excision of the knee, and knee arthrodesis with simultaneous bone transport using an Ilizarov ring fixator. Following 136 days of bone transport, the patient achieved radiological and clinical bony union after a total frame time of 372 days. He then commenced 50% partial weight-bear in a protective knee brace and gradually worked up to full weight-bearing by 4 months. The patient developed superficial pin tract infections around the k-wires on 2 occasions; these settled with a cephalosporin antibiotic spray and local dressings. At 13 years follow-up there are no signs of disease recurrence or failure at the fusion site. The patient is able to fully weight bear and stand independently on the operated leg. Knee arthrodesis with simultaneous limb-lengthening is an effective treatment modality following en-bloc resection of an aggressive chondroblastoma. The case is discussed with reference to the literature.

Figure 2: CT scan demonstrating the lesion in the proximal tibia.

Mentions: In July 1995 a 15 year-old boy presented with a 6 month history of pain and swelling in the left knee. On examination he walked with an antalgic gait, there was a moderate left knee effusion, and the knee circumference was 5 cm greater than the right side. Range of movement was severely limited to 0 to 40 degrees of flexion. There was no local lymphadenopathy and he was constitutionally well. Plain radiographs (Figure 1) and CT scans (Figure 2) demonstrated an osteolytic process in the proximal left tibia, and a second lesion in the medial femoral condyle. Laboratory tests were within normal limits and a chest radiograph was normal. Angiography did not show any abnormal neovascularisation, and Technicum 99 bone scintigraphy showed a relative accumulation of radionucleotide in the proximal tibia.
