Introduction: Chondroblastoma is a rare benign cartilaginous neoplasm arising in the epiphysis of long bones in young patients. It is an uncommon benign but locally aggressive tumor, mostly located in the secondary centers of ossification. These tumors arise near a joint or growth plate and surgical excision is always challenging.
Case Report: A 13-year-old boy presented with intermittent knee pain, swelling, and limitation of movements for 1 year. On examination, magnetic resonance imaging revealed a hyperintense lesion in distal femoral epiphysis with superior transphyseal extension and inferior thinning of cortex with cartilage breach. Histopathological examination confirmed the diagnosis of chondroblastoma of distal femur. We report a novel technique of approach in a case of distal femoral chondroblastoma in a skeletally immature individual.
Conclusion: The technique we incorporated had an adequate exposure to reach the lesion for a complete curettage and bone grafting. It also reduced further injury to cartilage and physeal plate.
Keywords: Chondroblastoma, cartilage breach, curettage, bone grafting.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
