Abstract
Introduction:Giant cell tumor(osteoclastoma) is benign, locally destructive tumor with low metastatic
potential, but it has tendency of recurrence after the treatment. The primary areas of involvement are the
ends of long bones, commonly the distal femur and proximal tibia. The most preferred treatment modality
of the giant cell tumor is surgery. Case report: A 54-year-old female presented with pain and slight
swelling localized over the proximal left tibia and limited range of motion in the left knee. After histological
confirmation of the diagnosis with open biopsy, en bloc resection of the lesion wasmade with reconstruction
of knee joint with semi-constrained knee endoprosthesis and trabecular metal. Conclusion: Selecting the
appropriate treatment method is very important for the recovery of the function of the affected joint and for
the whole extremity, as well. There is an advantage of en bloc resection and reconstruction with semi-
constrained knee endoprosthesis in combination with trabecular metal in cases with extensive destruction
of bone structure, recurrence, pathological fracture or difficulty in reconstruction after intralesional
curettage. Advantages in functional aspect of this treatment modality are retaining the stability of the knee
joint, substituting the bone defect and fast recovery of the function of the affected joint and limb.
