A case of a young adult with a recurrent Giant Cell Tumor of Bone. Previously, the patient underwent an improper intralesional curettage. After one year, he noted a resurgence of pain. He sought a consult with another physician, and he was advised of possible wide resection and an application of tumor prosthesis. However, the patient refused and opted for another procedure knowing the risk of tumor recurrence. Magnetic Resonance Imaging of the lesion revealed a recurrent tumor surrounding the bone cement construct. The tumor extended into the Anterior Cruciate Ligament Tibial attachment. We proceeded then to an extended intralesional curettage, cauterization, and application of hydrogen peroxide. A reconstruction of the tibial plateau roof was done using a tricortical Iliac bone graft, supported by a buttress plate and screws. Below the graft was a Gel-foam and finally, a block of bone cement was used to fill in the gap. Final outcome remains to be seen after a series of follow up.
