Zoledronic Acid-loaded Bone Cement as a Local Adjuvant Therapy for Giant Cell Bone Tumor After Intralesional Curettage: a Prospective, Multicenter, Single Blinded, Randomized Control Trial.
The purpose of this study is to investigate whether zoledronic acid-loaded bone cement (4mg ZOL+ gentamicin PMMA ) as adjuvant method can decrease local recurrence in patients with giant cell bone tumor following intralesional curettage surgery. The hypothesis is that patients with local administration of zoledronic acid to the bone cement has lower relapse rate compared those with traditional bone cement(gentamicin PMMA ).

• lesion amenable to reconstruction (intralesional curettage) defined as having at least one intact column of bone after removal
• no previous systemic bisphosphonate or denosumab therapy
• with expected longer than 18 months of survival time
