title: Intra-articular recurrence of benign chondroblastoma with articular involvement at initial presentation--a case report.
abstract: We report a case of chondroblastoma involving the upper tibial epiphysis, which had an unusually aggressive course, with articular involvement at initial presentation. Intra-articular and soft tissue recurrence occurred after treatment consisting of curettage and bone grafting. Although the incidence of local intraosseous recurrence of chondroblastoma is relatively high, intra-articular and soft tissue implantation is rare and is usually due to intra-articular spillage during surgery. Spontaneous articular involvement is rarely seen.
